Neural Exosomes: Diagnosing Alzheimer’s Early

Neural Exosomes

References: Alzheimer’s DementScience Direct,

Neural Exosomes? Sound like Greek to you? Ever heard of them? You should have. Here’s the scoop. First, they aren’t rare. You have about some 1.2 billion of them per ml of blood. They are tiny little spheres of membrane that have budded off of neural cells. Much like the tiny vesicles that bud off a nerve cell to transmit nerve impulses between cells, exosomes are 2-3 times the size of those packages, and designed to travel further to other cells. Instead of neurotransmitters, they carry RNA instructions. Many come from the brain, but many come from other organs.

What makes them unique is the surface markers on them and the RNA in them, including messenger RNA, mircoRNAs, DNA and signaling proteins. They are not fully functional cells, they are tiny little spheres of membrane, lined/filled with all these unique markers. The range of function that is being proposed for them is that of signaling between cells, moving cellular components, like amyloid precursor protein or messenger RNA. What is known is that you can measure them in quantity and specificity way before you come down with disease. In particular, they show up as much as 10 years before your develop Alzheimer’s. Did you get that? They give you the markers of advance warning.
Now, it’s not just that advance warning they give you. Each exosome has within it a unique pattern of micro RNA and messenger RNA. What are those doing? Did you know that your own chromosomes are actually only 2% coded for your unique genes? That’s it. But did you know that the other 98% isn’t junk? It’s your instruction manual. Messenger RNA is how you send out genetic code about what to do when. This is how your body responds to development as you move from a single egg into a fantastically complicated human. Some of that code is good for you and builds you up. Some of it is like napalm, and attacks the enemy, tearing you down. And,…..here is the critical point. The messenger RNA is also how you send out instructions on how to respond to disease/threat/illness. All disease. Each condition merits different sets of instructions. That means Alzheimer’s will have different proteins in its exosomes than Lyme disease, or pancreatitis, or rheumatoid arthritis, or pneumonia. Another example function, we believe that exosomes are how we clear Amyloid Precursor Protein, APP. Lousy clearance results in accumulation of amyloid in your brain. We call that Alzheimer’s If we can learn how to interpret our Alzheimer’s exosome and how they are different, we can learn how to anticipate and react proactively. Learning how to read exosomes gives us the code to our “instruction manual”.
Now, what is coming is the next miracle. There are companies developing the software to interpret these tests who are just months away from commercial release. With that, we will be able to tell you just what you need to do next. Remember Star Trek’ Dr McCoy and the Magic Wand that would diagnose everything? Yup. That’s it. We are almost there. Maybe not a wand, but an exosome reader. It’s complicated. It is the epitome of “Big Data”.

A point of trivia: do you know how much DNA is in you? Here goes. One cell’s human DNA would stretch out about 2 meters. And considering that we have some 20 trillion cells, one human’s DNA would stretch from the sun, way beyond Jupiter. That’s a lot of DNA. Now, consider that over 99% of the DNA we carry around is actually in our gut in the bacteria of our colonic biome, now we are talking a lot of code that could be in exosomes.
WWW.What will work for me. I’ve finished Bredesen’s Certification Course this week and am just blown away by the possibilities of what we can do to reverse this wicked evil disease. It’s thrilling. And its sad. My 92 year mother with Alzheimer’s is too late to be helped. It makes this Mother’s Day bittersweet. I hope you are able to celebrate with your Mother. In a few months, we will be able to keep her safe from Alzheimer’s. In the meantime, I’m focusing on getting a good night’s sleep. You clear Amyloid much more effectively with good sleep. Maybe that’s why you feel so refreshed when you wake up.

Eat Spinach, It’s High Fat Food

Eat Spinach, it’s High Fat Food

References: WikipediaBMJHarvard HealthJ Clin GastroScience Based Medicine,

I’ve learned that sugar and white flour is bad for my brain, my weight and just about everything else. Everyone around me is on a Keto Kick trying to lose weight with the Ketogenic diet. And it doesn’t work for me. How can I eat a high fat diet? And what I’m most worried about is my brain. How can I prevent Alzheimer’s?
Well, step one and two of Bredesen’s RECODE program are to eat a low carb high fat diet, and to not eat each night for 12 hours. This is how you teach your brain to run on ketones.

The conundrum comes when I try to eat low carb by having steak, bacon, eggs and cheese. And then my weight doesn’t budge. What gives? Turns out that animal protein and fat are not so good for us. Animal protein turns on the mTOR gene, that makes me age faster. I don’t want to do that. In the last few years, two studies about eating more animal and heart disease have bothered me. A BMJ article from Sweden shows that men who eat animal protein have a 5% increase for heart disease for every 5 gram increase in animal protein. And the Harvard Professional Men’s Study showed that men in the top quartile of meat consumption had 70% more heart disease.

What’s a person to do? Well, eat more vegetables. Guess what happens to vegetables and resistant starches? Where are they digested? Turns out not in your stomach, and not in your small bowel but in your colon by the biome of bacteria in your colon. Resistant starches are carb rich foods prepared in a certain way or eaten before fully ripe. Green bananas, for example are quite resistant and get digested in your colon into short chain fatty acids. Ditto for Peruvian potatoes, cooked and then cooled. The amylose molecule changes its shape with heating, and then again with cooling, making it indigestible in your upper gut which delivers it to your colon, where the bacteria break it down to short chain fatty acids. Propionate and butyrate are amazing super foods. They are the short chain fatty acids that nourish you and your whole body. They are fats. Eating spinach makes for fat. Green beans, ditto. Asparagus, broccoli, cabbage– if it’s above ground, its probably going to go the same route.

Enter the Kitavans. A small island off New Guinea where 80% of folks smoke, but they eat no sugar or western food, and have 70% of their diet from resistant starch and coconut. They are all slender, have no vascular disease or AD. One could properly conclude that their diet is high fat: a combination of coconut and resistant starches from yams and taro.
Hence, a vegetable based diet can be ketogenic. Get it? Eating salads with lots of olive oil, is more fat based than you thought. Do you see the path forward?
www.What will work for me. I went to a Mexican restaurant last night. We had guacamole for hors-d’oerves and I had a shrimp and avacodo/lettuce salad. I felt quite smug navigating a typically high carb, high animal fat environment and escaping feeling good about my meal. This morning, a spinach omelet. I’ve finished 3 cycles of the Fast Mimicking Diet and I’m done another 4 pounds.

Fast Mimicking Diet 5: Cancer and the Magic Shield

Fast Mimicking Diet 5: Cancer and the Magic Shield

References: CellBMC CancerCancer CellPLOS Biology,

Last week we learned about reversing diabetes. This might be the Holy Grail of modern medicine. The prevention and treatment of cancer might be just as important. Cancer frequency increases with age, essentially equating aging with more disease. How to prevent it?
The first key concept is to understand how cancer comes about. It takes a key mutation, or probably several mutations or changes in the DNA sequence of a cell, for the cancer cell to develop “oncogenes”, cancer favoring genes. Cancer cells stop obeying orders, which in fact makes them weaker and more vulnerable to damage from external toxins. This is why Vitamin C, ozone, and many chemotherapy drugs have a deterring effect. It’s as though cancer cells are race cars with the accelerator stuck to the floor: they can’t slow down.

Longo recognized that key characteristic of cancer cells, and the essential response of healthy yeast/worms/mice to the fast mimicking diet. When you deprive healthy cells of key nutrients for a fixed period of time, they recognize that they are in trouble. The “get the memo” and respond by hunkering down. Longo called it the “magic shield”. Cancer cells can’t do that. The cancer cell tries to keep growing, even with no nutrients around.

In an experiment with mice, one of Longo’s graduate students gave mice chemotherapy and compared a group with normal daily diet versus some fed no food for two days prior to the chemo. The differences were striking. The fasting mice were dandy, the normally fed mice all got sick. In a week or two, 65% of the regular diet mice were dead. The same dramatic effects were found when micewith lung cancer were given chemo with or without fast mimicking: the fasting mice had 60-70% remission rates compared to much lower in the normally fed mice.
It appears there are two key dynamics going on with this cancer effect: the first is that the fasting weakens the cancer cells, making them more vulnerable. The second is that it renews and “revs” up the immune system, making it more aggressive against the cancer cells..

And the effects go beyond just making the immune system stronger. The use of potent steroids is a part of many chemo regimens with mixed blessings as the resulting elevation of glucose adds to toxicity. The FMD reduces glucosedramatically, suggesting that the use of steroids should be reconsidered.

Where are we with randomized clinical trials in cancer? Considering that there are several hundred types of cancer scattered all over, it takes a while to conduct studies on any one cancer with this strategy, so there are very few studies completed. The three or four that Longo refers to in his book make the strong argument for safety of the strategy, reduction of side effects, increased ability to complete chemo regimens. With that in hand, Longo suggest the following guidelines in his book. 1. If the oncologist agrees, the patient may fast or do the FMD for three days before chemo and 1-2 days after standard chemo drugs. 2. If fasting, make sure you don’t resume regular eating immediately following the chemo as the rebounding growth of liver cells at a time of lingering blood levels of chemo lead to liver toxicity. Weather it out with fasting at least 24 if not 48 hours after the chemo. And start slowly on vegan food, with lots of olive oil: rice, bread, pasta, vegetables and soups. Finally, try to return to normal body weight between cycles. If on any diabetes drug, please, please consult a knowledgeable physician first.

WWW. What will work for me. And just what do you want to do if you have high risk for cancer? Start by reading Longo’s book. If I had the BRCA gene, I would be doing this diet for the rest of my life. I do have diabetes genes in my genetic code, so I probably will be doing this the rest of my life, just like all of us should be. Your blood tests will tell you how often you should be doing it. In the meantime, I’ve now seen three people with dramatic success in just a few months with their diabetes getting better. Want to join that list?

Fast Mimicking Diet 4: Reversing Diabetes

Fast Mimicking Diet 4, Reversing Diabetes

References: Whitehall StudyCirculationAgingDiabetes CareCell,

This is a big deal. If you read no email this year but this one, you will be well served. The reversal of diabetes is so important, it is a game changer for all of medicine. Why? Two reasons.

The first is that it is so destructive, effecitively being the cornerstone for all our diseases of modern society. We have defined diabetes by committee and decided that it really wasn’t a disease until you got to a blood level of 124 or so, measured twice, or a Hemoglobin A1c of 6.2 or 6.4 (Remember: the A1c is the percent of hemoglobin molecules with a glucose stuck on them. Red cells live 100 days, about, which makes the A1c a nice surrogate marker for your average glucose over the last 100 days.. But that is looking at a disease you might think about treating. What would happen if you decided to consider what blood sugar results in optimal function? I would refer you to the Whitehall Study from England, It showed that for every point of glucose above 86, you have a 5% increased risk of heart disease. And there is wide acknowledgement now that we need to lower blood sugar, which modern medicine does by treating with drugs. That means an optimal blood sugar should be 86. Bredesen shows abundant evidence that a HgbA1c of 5.5 is what you want if you are anxious about Alzheimer’s.

The second is that everyone has it. There are all sorts of papers saying how many millions of people have it, but that is the DISEASE. If you want optimal function, the picture is much gloomier. The simplest explanation of how your body progresses to diabetes is as follows: your fat cells become insulin resistant in relationship to their size. As you get fatter, your fat cells get bigger. You don’t make ore. And your insulin receptors get further apart, So you become insulin resistant. You raise your insulin to keep that blood sugar in control, which you can only so for so long. After a while, you run out of the ability to keep raising your insulin level. It’s as though you were only given so much insulin in a lifetime. As long as you were only burning a tiny amount a day, you can live a very long time. But it has become pretty apparant that once we get overweight, we are burning up our insulin supply faster than we can maintain for a lifetime of 100 years. And that is what we see today in modern medicine. As we age, being a bit plump gradually turns into our blood sugar slowing rising, and your being put on one pill after another until you get to age 55 or so, and then you flunk out and get put on insulin. Your islets in your pancreas look shaggy with fewer healthier insulin producing cells. And then your kidneys fail and you get on dialysis, and then you flunk and get Alzheimer’s. Till now, the key to reversing diabetes has all been about losing weight, making fat cells smaller and getting the residual ability you have to make insulin in line with your reserve of insulin producing capacity. Imagine having an insulin level of 35 when you weight 190, but a level of 2 when you weight 132. That’s what we see clinically happening.

Here is where the Fast Mimicking Diet (FMD) comes in. What would you think if I told you that the FMD turns on the genes that literally wipe out old, dead, decaying tissue and starts rejuvenation of new insulin producing cells? Yes, produces new insulin cells. We have never seen anything quite like this before. This is like the holy grail of medicine, and it’s right there in front of our faces. The FMD turns on genes that support resiliency, getting rid of old garbage that’s in the way and turning on the growth of new stem cells. This is dieting for your genes sake. And all we are asking of you is 5 days a month until you have got yourself fixed.

WWW.What will work for me. I’ve been getting older and I have a family history of diabetes. To my alarm, this year my A1c ticked up from it’s usual 5.2-5.4. I’ve already done one cycle. I’m starting cycle number two. I just came back from a trip to see old friends I grew up with in India. I’m going to send them copies of Longo’s book. My advice to you is to not trust me, or your own doctor on this topic. Trust your own lab results. Watch your own response. The data is there. This diet will eventually become the “human diet”. We will all be on a variation of it. The good news, if you don’t have any risk factors, is that you only need to do it twice to three times a year, provided you exercise properly.

  1. Diabetes starts at a Hemoglobin A1c of 6.2. T or F                                         Answer: true, if you call it as the disease and use current medicine’s standards. Optimal is a whole different story. If you have worries about heart disease, Alzheimer’s. autoimmune disease.. or just want to age gracefully into your 90s, you want an optimal A1c: below 5.5
  2. You can lower your A1c by losing weight. How does that work?                    Answer: your fat cells get smaller and the residual insulin you have left become in line with the amount you need to control those fat cells.
  3. If I’m getting a little older and a little heftier, what is happening to my insulin producing cells in the islets in my pancreas?                                                                                 Answer: They are getting fewer and making less insulin.
  4. How many days do I have to do this diet thing?                                                Answer: 5. Four, as best we know, isn’t sufficient.
  5. What is an optimal blood sugar?                                                                         Answer: Your family doctor will tell you under 100 or so but won’t call you diabetic until you are 126, or if they are just checking your urine, you will be normal when you have a sugar below 180 because your kidneys can reabsorb anything below 180. (I kid you not, I talked to a person this week whose doctor was still checking urine for diabetes.)

 

Fast Mimicking Diet 2: The Human Method Simplified

Fast Mimicking Diet 2 The Human Method

References: Longo: The Longevity Diet, ScienceGut,

Last week we heard about yeast being used to explore what genes are needed to make the right environment for longevity. Valter Longo’s hypotheses was that those same genes exist in mammals, humans included. If he could make the same changes in longevity by diet and its effect on genes in mice that he made in yeast, he would have a huge scientific win. He started looking at mice and their genetic code. Mice live about two years and start getting cancer around a year and a half. That makes a useful model.
What did he find? The exact same thing. Two key ideas. Extra sugar activate the PKA gene. That causes trouble. Mice with lower PKA activity, live longer. That simple. And extra protein activates the growth hormone receptor and TOR-6SK and increases the level of insulin and insulin like growth factor. Certain amino acids appear to be more potent at activating the TOR-6SK complex, like leucine. which then accelerates aging. That’s it. The foundation of aging down to two simple key processes. Too much sugar, and too much protein. That duo is the foundation of what Longo called his “basic juvenology research”, one of his Five Pillars of Proof.
The story is all about the nuance of glucose and protein.

Our body runs on glucose. It is our preferred food for our brain, if present. The story is all about how it is delivered and what happens to our bodies if we get too much, too fast. When you get low glycemic carbs from vegetables, your blood sugar rises very slowly and you hardly get an insulin response. (For example, it takes 19 cups of asparagus to make 50 grams of glucose). If you have a diet of broccoli, spinach and green beans, you hardly get any insulin spike at all. A substantial portion of those vegetables make it to your colon where the biome in your colon changes those coarse fiber rich foods to short chain fatty acids, just like in gorillas (See this column from 2 weeks ago). Just like with gorillas, a high fiber diet actually results in substantial increase in fatty acids, or fat. Adhering to a Mediterranean Diet appears to make this possible, all due to the activity of the biome in your gut.
A high protein diet changes your gut biome and increases many markers of cardiovascular disease,TMAO (trimethylamine oxide). So we have seen these changes from other lines of research as well.

We are even beginning to understand the incredible complexity of our gut biome. Our colon is there to take high fiber foods and digest them for us, releasing short chain fatty acids, turning low glycemic vegetables into short chain fatty acids. Bacteroidetes are more abundant in the stool samples of those eating a mostly plant based diet, while Firmicutes were more abundant in those who eat a more animal products diet. From those major families, the specific bacteria Prevotella and Lachnospira were more common in vegetarians and vegans while Streptococcus is more common among the omnivores with higher meat intake.

Can we take this to humans with specific guidelines? Well yes. This is what Longo has come up with. Protein should be about 0.31-0.36 grams per pound per day, of which about 40 grams for women weighing 130 and 60 grams for men weighing 200. Once you hit age 65, you likely need a little more protein, but not that much. Just a little.

Your diet should be rich in healthy fats like olive oil, fish and coconut oil, walnuts and almonds. These fats essentially do the same process of helping you get more calories from fat, like the gorilla. Trans fats and saturated fats are to be avoided. And there should be plenty of Healthy Carbs – the type that make it to your colon and turn into fat. They generally have a glycemic index under 20, or 45 max which would include beans (if you aren’t lectin sensitive). The carbs that get digested in your small bowel and make sugar spikes look like ground flours of any kind, sugar in particular, high fructose corn syrup in double particular, fruit juices or too much modern fruit (modern apples are nowhere near the original Himalayan apple – ditto for pears, bananas, on and on that we have altered in the last 100 years to be much richer in sugar). Most grains are just too rich in carbs to be too good for you, unless you have changed them to be resistant, usually by cooking and then cooling. Same with potatoes. The original potato from Peru was a fine food with a GI of 40. Now it’s a glycemic index of 80-95, unless you boil it and cool it making it resistant. (Is this enough to confuse you a little?)
Finally, cut your meals down to 2 and a snack. Try to fit all your food into 11-12 hours of eating and not for 3 hours before bedtime. Breakfast is NOT the meal to skip as there is plenty of evidence that that habit correlates with many illnesses.

Ok? Next week, we will discuss how to FAST and do it right so that you kick start your genes into being supercharged. It’s cool, and it works.
WWW. What will work for me. This is evidence based and I get it. I’m so fascinated that I drew my own lab tests and started doing it full bore, as much as can be done living in a modern 8-5 work world. It’s the fasting part that has my attention. I’ve completed my first 5 day session and intend to do it again. It wasn’t so hard. More next week.

Lectin Lesson 5: Resistant Starch is a High Fat Diet – Ask the Gorillas!


References: Steven Gundry’s Plant Paradox, Journal NutritionJ. Internal MedNature,

Once upon a time our diet was very similar to gorillas. Say some 10 million years ago, and prior. We ate leaves, in Africa. Only 8 million years ago did we diverge from chimpanzees and only 2 million years ago did our brains start getting bigger in response to eating meat. We had learned to run long distance, which made us the most successful hunter in Africa. But our guts were still used to eating leaves, and designed to do so.

What happens on eating leaves? Leaves are very dense, high fiber foods. Gorillas eat about 16 pounds a day, in today’s gorilla. The gorilla can’t digest those leaves, but their gut biome can. The bacteria in their gut break down the leaves and convert the cell walls of those plants into tiny, short chain fatty acids. Net effect, the gorilla’s diet becomes 70% fat, ideal food for brain and nerve cells. What looks like a high fiber, low fat diet turns into a high fat diet when the gut biome is properly nourished and contributes like it was designed to.
Now, let’s make a pivot and see if we can find anyone on this planet who eats a high fiber, high fat diet. We end up with a unique society in remote New Guinea called the Kitavans. A Swedish Researcher, Lindeberg, did a studyon the Kitavans who eat virtually no western food, 70% carb, and 20% fat and have absolutely no obesity, no heart disease, no diabetes and live into their 90s, while smoking. Imagine that!
How do they do that? They eat a ton of resistant starches in the form of taro, coconut, fruit and fish. We find much the same from Tokolau, another remote Polynesian Island with no western food: just mostly coconuts and fish.

The key is that idea of resistant starches. These are “carbs” that don’t act like most carbs. They don’t get digested in the small bowel. In the process of cooking their molecular shape is changed.  They are passed on through to the lower gut where they are ideal foods for your gut bacteria. Your colonic biome goes nuts with happiness and digests them down into short chain fatty acids, turning what looks like carbs into fat. This is the same hat trickthe gorilla does in their gut. Not only that, with all that food, the bacteria make a thick coat of mucus in your gut and you make a much more effective barrier to absorbing those dangerous lectins and LPSs fats that turn on inflammation – so you make a better natural barrier. Resistant starches reverse the damage of red meat. Now, many resistant starch foods are high lectin foods: boiled and cooled potatoes, rice – cooked and cooled, beans and oats. Gundry acknowledges this and advises you eat green bananas. Not ripe ones where the carbs are sweet and absorbed, but green where they are still resistant.

Turn on the lens of resistant starches and suddenly long lived societies around the world come into focus. They all have the same features in common. Their diets show high fiber diets of resistant starches, which their colonic biome turns into short chain fatty acids. Their brains get high fat intake. On Okinawa, the fiber is in the form of yams. Sardinians and Cretans eat high fat in the form of olive oil. Seventh Day Adventists are vegetarian, but eat about 60% fat from olives and peanuts. The Mediterranean diet goes straight for the olive oil, making an approximate high fat diet. We know your brain does better eating fat. It has to be the right fat. And having your colon make it for you appears to be the right concept. Thank you, gorillas.

WWW.What will work for me. Gundry is turning our dietary concepts on its head. But data is data. The Kitavans make for a unique example. Ditto from Tokolau Island(70% of diet from coconut). There is rice being developed on Okinawa that is particularly resistant. I’m curious if I can find it. I’m not taking up smoking. But will I eat a bit of rice now? Yes, if it has been cooked and then cooled down. Raw banana, well, I’ll try one.

Lectin Lesson 4: What Elephants Having Heart Attacks Teaches Us About Cancer

References: Steven Gundry’s The Plant Paradox, CirculationScience Direct,Front Oncol., Glycobiology,

Ok, caught your attention? Elephants having heart attacks? Yes, it’s true. Now, when elephants live in their natural habitat that has sufficient tree and brush forage, they never get a heart attack. In the last couple of hundred years they have lost habitat and been driven to eating grasses. Elephants don’t eat grass when they have natural leaf habitat – they eat leaves. When they eat grass they develop coronary disease, just like us. Why does that happen?
We share an odd and uncommon sugar with elephants. It is called Neu5ac. I’ll call it N-A. It’s a member of the sialic acid family of sugars. We share it with shellfish, chickens and elephants. When we diverged from chimps 8 million years ago, we started making Neu5ac (N-A). Chimps make Neu5gc (N-G). As do every other mammal including the ones we eat like cows, goats, sheep, pigs. This sugar, N-A) is like a signal in our gut cells and our arteries. And grain based lectins bind avidly to it. WGA, the lectin in the wheat germ, binds avidly to it. Avidly. But grain lectins don’t bind to N-G.
Here’s where the link happens. When we eat red meat containing Neu5gc – N-G, your immune system recognizes it as foreign and makes antibodies to it. Those antibodies then turn around and attack your own Neu5ac (N-A) receptors. You get antibodies on your blood vessel walls. You call in white cells. Coronary artery disease is off and running. When elephants eat grasses, they get the same cross reactivity. Something about having grass (wheat) based lectins that attach to Neu5ac and eating the Neu5gc form of the sugars makes for that autoimmune attack.
Now, swing over to cancer. Human cancers have a lot of the Neu5gc protein in them. They put it on their surface as a means of hiding from our immune system. Wait a minute! We don’t make it. Human cells cannot make Neu5gc. Right, we don’t. Then how does the cancer get it? From our eating it in red meat. That may be the link between our eating excessive red meat, and having more cancer. The more red meat you eat, the more N-G you get to supply cancer cells with camouflage. Did you notice that chicken and shell fish don’t have N-G. They have N-A, just like humans and elephants. When you eat chicken and shell fish, you have less risk of heart disease and cancer.

The mechanism that is driving both of these phenomenon is the presence of these sialic acid sugars called Neu5ac versus Neu5gc. Their subtle name difference is the whole universe of immune recognition. That simple little alteration is all it takes for your immune system to go the wrong direction and start a process that leads to the slippery slope of coronary artery disease, or cancer.

WWW. What will work for me. This is a smoking gun. It tells us the clear mechanism by which this elegant, delicate signaling system shifts our immune reaction against either ourselves or against our own immune vessels. Or cancer. It’s simple. We get B12 from red meat. We have to have it. A tiny bit. I mean tiny bit. Seems like we need to start thinking about how we can change the balance of calories. If ketogenic eating is important for our brains, then it has to be with healthy fats, not meat. And it all comes down to those magnificent gentle animals, elephants.

Lectin Lesson #3: How Lectins Make you Fat

Reference: Gundry’s The Plant ParadoxAm Jr Physiology,

Did you know that humans lost height and brain case size in the 1000 year transition from hunter gatherer to wheat grower. Gundry quotes this in his book as what has been discovered at archeological sites from those time periods. Civilization had its costs? All so that we could have kings and cities and armies and compete with your neighbors more effectively. Hmm. And we started domesticating pigs and cows, sheep and goats….so we didn’t have to go hunting. Here is Grundry’s conjecture. Wheat and lentils are amazing grains. When you eat them, you gain weight faster and more efficiently to that you can make it through winter more efficiently. Civilization liked wheat, because by putting calories on into storage, those who ate it lasted longer.
Now, extend that to today and see if it’s any different. What do we feed cows before we slaughter them for market – corn and beans? Wild pigs are lean animals. Domesticated pigs have lots of fat (we call if bacon) when fed corn and beans. Those foods make animals fat too. So Gundry’s hypothesis is that humans didn’t choose wheat and lentils to grow because they could be stored, but because you put weight on the most effectively with them. That’s his Plant Paradox. The very plants (wheat and beans) that allowed our ancestors to develop civilization and store calories for the winter were the same plants that hastened our demise from metabolic diseases. Now, that was hidden for the last 9,000 years because we died of measles and tuberculosis and cholera by age 30 anyways, and didn’t see the degenerative effect of inflammation caused by these grains. Grains became the means to civilization not because they could be stored, but because they were the most efficient means to put on weight and make it through winter. They promote more calories into fat deposit than any other food. And then, isn’t it curious that milk from black cows, so called A-1 milk, has lectin qualities to it too in its BMC-7 fragment, and promotes weight gain.
Ok, I get the historical conjecture but is there a coherent biological explanation for how this works? Yes, indeed. It goes as follows. Two key processes are going on.

First, the disruptive effect of the lectin in wheat called WGA. Wheat germ agglutinin. It looks a lot like insulin. Acts like insulin. That’s what lectins are, proteins that mimic mammalian proteins and cause damage by disruption. WGA mimics insulin, badly. Insulin attaches to a cell for a tiny amount of time, then lets go. WGA doesn’t let go. On a fat cell, the message is to take up glucose, forever and ever. That fat cell gets fatter. On a muscle cell, however, the message is to block insulin effect so muscle are starved. Again, WGA doesn’t let go so the real hormone that should be on the receptor can’t dock on its receptor and tell the muscle cell to take up glucose and run with it. Same effect on nerve cells: WGA clamps on and doesn’t let go. Nerve cells are starving. But they send out the message to the organism: “Eat more.”
Even more disturbing isrecent evidence has emerged that lectins can climb up the vagus nerve from the gut to the brain, damaging the substantia nigra, the seat of Parkinson’s disease. Indeed, cut the vagus nerve and the risk of PD drops 40%.
The final argument to support Gundry’s hypothesis might be called the Common Soil Hypothesis – that the mechanisms of metabolism and inflammation are curiously linked. You got fat because your body is at war with itself. And it goes as follows. The lectins set off your “Tiny Little Radars”, your Toll Like Proteins, that reside in your blood vessels and fat cells. They set off cytokines (your body’s fire alarms) calling for white cells to respond to clean up the invading bacteria. Except there are no bacteria. It’s just lectins. But the white cells show up. And your body shifts into war mode. Energy goes to the troops, the white cells. The stay-at-home folks, (Gundry calls them civilians but you think of them as muscle and brain cells) go on war rations and get less. Hence, you become insulin and leptin resistant not because you are overweight, but because your body is inflamed from all the fake lectin signals setting off fire alarms about invading bacteria. Your body is at war, thinking you have been invaded by bacteria, and you are all pumped up and ready to defend. Except that there is nothing to defect. The home folks starve. Fat cells get bigger.

Get it? Stop the war, send the troops home. Weight loss follows automatically. Stop eating lectins. That includes A-1 milk and cheese, nightshade plants, wheat and beans and most of all, genetically modified foods with their genetically inserted extra lectins.

www.What will work for me. This is a paradigm shift type of thinking, but it makes perfect sense. I get it. I just have to figure out how to implement it. And wheat is lurking behind every food in America. And every meat product was raised on lectin foods: corn and soybeans so the lectins in those foods are still there for me to absorb. I have to live with this a while. But I can shift a little. Less beans, less wheat. One step at a time.

  1. You are leptin resistant and fat because you eat like a pig? T or F                      Answer: That’s backwards, unless you take eating like a pig to mean you are eating corn and beans, lectin foods. The proper answer is that leptin resistance and fatness comes from the natural shifts your body makes to counter the fake messages caused by eating lectin containing foods. You eat secondarily because your brain cells and muscles are starving, ironically.
  2. Lectins set off inflammation because they activate TLRs? What are TLRs?
    Answer: Toll Like Receptors or “Tiny Little Radars” in Gundry’s clever nomenclature – your natural bar code readers watching what’s in your blood to sort our friend from foe.
  3. You can make great bacon with wild boar? T or F                                                  Answer: Patently false. To make bacon on pigs, you have to feed them corn and beans.
  4. To make bacon on you, the best foods to do that with are?                             Answer: Same as with pigs. Corn, wheat and beans
  5. Ipso facto, to lose weight you need to ?                                                                Answer: create the environment whereby you “stop the war”, turn off inflammation, rid yourself of lectins, eat what nature intended you to eat.

 

 

Lectin Lesson 2: How Lectins Cause Damage with Inflammation

References: American Heart Sci Meetings,Jr, ImmunologyResearchgateWikipediaAthersclerosis,

Just what is going on with lectins? What’s the big deal? Do they really cause trouble?

To understand those questions, you have to understand the complement system in your body. This is not about saying a nice thing to you about your hair, or your necklace, this is about your basic lizard brain immune system, your innate immune system. Your innate immune system is the first to respond to threats with non-specific responses. If you think of a series of dominoes, each of which knocks over two more, the innate immune system is the means by which your body kicks back immediately against external threats and makes immediate reactions that happens quickly in response to “invasion”. A cascade of chemicals create tags to place on the invader to tell a white cell to eat that particular invader, (Opsonization is the fancy term) or punches a hole in the wall of the invader with donut shaped proteins so the invader leaks its guts out. You can imagine, this has to be carefully controlled as if it balloons out of control, you get the shaft and your own cells get damaged. The adaptive system, layer two of your immune response, takes longer to gear up and make specific antibodies shaped precisely to attack the invader, or specific white cells armed with bar code readers to find and destroy the invader. Doing all that takes time. In the short term, the complement system is it.
There are several pathways into the complement system. The classical pathway, the alternative pathway and the LECTIN PATHWAY. Did you get that? The lectin pathway is one of the ways you set off your innate immune system. To understand this pathway you have to be able to read the following sentences without pausing: This pathway is initiated by the binding of mannose-binding lectin (MBL), collectin 11 (CL-K1), and ficolins (Ficolin-1, Ficolin-2, and Ficolin-3) to microbial surface oligosaccharides and acetylated residues, respectively. Upon binding to target molecules, MBL, CL-K1, and ficolins form complexes with MBL-associated serine proteases 1 and 2 (MASP-1 and MASP-2), which cleave C4 and C2 forming the C3 convertase (C4b2a). If you drill down into that, it simplifies to the sugar mannose that is part of many plant lectins, and your complement system watching for that sugar signature to fire off a response. Ficolins are protein lectins that come in patterns of five at a time, and also set of the lectin pathway.
Here is the rub. There is now evidence that a low lectin diet will decrease endothelial dysfunction (code word for the first step in coronary artery disease).

What’s the final implied conclusion? This is a new way to look at heart disease. Lectins play a roll is setting off inflammation. That’s a given. Lectins in the human diet have increased dramatically in the last 200 years as our foods from all over the world have become part of a new diet that never had those foods before. And in the 21st century, we have added all sorts of chemicals to our environment that allow our gut to “leak”: NSAIDs like ibuprofen and naproxen, steroids, antibiotics, PPIs. And we have genetically modified many of our foods to create grains resistant to insects by intentionally inserting more lectins into the genome of plants that we then eat. We have tilted the playing field. The slope is in the wrong direction to maintain health.
WWW. What will work for me. I am eager to learn this stuff. I was at a small plate restaurant this weekend and intentionally chose a low lectin dinner: grilled Brussel’s sprouts and calamari. I slept better last night. Hmmm. Don’t know if that’s linked. One meal does not a heart attack prevent, but Gundry has shown that a low lectin diet will reduce damaged blood vessels “endothelial dysfunction” in just a few months. I’ve been off ibuprofen now for two weeks. Never again.

Copper, Another Cause of Alzheimer’s

References: Dr. WeilJ. Biological and Inorganic ChemistryFront Aging NeurosciJr Nutr Health AgingPro National Acad Sci., NeurologyEuro Biophy Jr,

We have established that iron is a problem in Alzheimer’s Disease (AD). That’s clear. But are there other links? What else has changed in Western Society? One example is clean water, delivered through sterile pipes made of………copper. That is new in the last 100 years.
Wast AD rare 100 years ago? Yes. In 1900 it wasn’t even mentioned in Osler’s compendium of medical diseases. That was at a time we had over 3 million folks over age 60, and at today’s rate of AD, there should have been 36,000 cases in the USA, enough to have been noticed and commented on by Osler. So, it’s new and it’s common.
Sparks and Schreurs published an article in 2003 looking at free inorganic copper added to rabbits drinking water at a concentration of 0.12 parts per million caused AD like pathology in their brains and damaged their memory. The EPA allows 1.3 ppm of free copper in our water. That’s allegedly safe. Singh confirmed the exact same results in a mouse model of AD in 2014.
The key here is the difference of “free” copper, loose in your blood and lightly bound to albumin and organic copper, tightly bound and regulated attached to a protein called ceruloplasmin. The free copper is a problem. Squitti showed that free copper is elevated in AD, but not in vascular dementia and its ratio of free copper to bound copper predicts the range of dysfunction. Free copper comes from copper pipes. Organic copper comes from food. Don’t confuse the two, they are different in their biological behavior. Organic copper is bound to proteins, carefully guarded and processed. Free copper is not bound and is not in the protection system of the body.

Where do we get “free” copper from. Our plumbing. 90% of American homes have copper pipes in them. The use of copper took off after WWII as did the incidence of AD. It should be noted, the Japanese were hesitant to use copper and didn’t use copper in internal plumbing. They have had MUCH less AD. When Japanese move to Hawaii, they lose that advantage and develop AD just like everyone else.
What does copper do in the brain? It appears to be part of the APP and APOe protein pathology. It certainly causes oxidative stress on brain cells. It may be simpler than that. The APOe 2 gene has 2 binding sites for copper, the APOe3 gene has 1, and the APOe 4 gene (the bad one) has no binding sites for copper.

Here is the proposed sequence for copper
1. You live in a home with copper pipings.
2. Your brain copper rises as you get too much in your water
3. Your copper removal system kicks into gear, the APP system works on copper like it does on iron.
4. You have an APOe 3 gene (lousy with only one binding site) or worse, an APOe4 with no binding sites – so you can’t get rid of it at all
5. Your brain churns and churns, trying to get rid of copper with the APP protein, and it just can’t do it because you have too much copper in relationship to your APOe risk.
6. You overwhelm your brain cells. They die. You slow down.

You can’t change your genes. You can change your water. Brewer studied several hundred American homes for copper levels. He found that about a third had copper levels above 0.1 (damages rabbits and mice), about a third had levels below 0.01 and a third were in-between.. Your pipes are killing your brain.

www.What Will Work for me. I’ve been startled by checking zinc and copper levels for the last year. I have had two or three couples whom I have seen who have normal zinc and copper ratios. To a person, they have all had normal zinc copper ratios. (Remember, zinc and copper work like a teeter-totter. As copper goes up, zinc goes down and vice versa.) Healthy brains have more zinc than copper. Everyone else has low zinc and very high copper. When I went to Burma last spring and asked about AD at a nursing home we visited, I was met with curiosity and confusion. They had never heard of it. Thirty residents over 70 should have had some dementia. Their water source: a single iron pipe, outside in the courtyard. Hmmm. For now, I’m taking zinc every day. I’m thinking about how to get my water checked.
