When Wendy Pogozelski began studying the primary literature in the field of nutrition, she was shocked to find enormous differences between the nutrition advice she’d found in the mainstream vs. the research and clinical results she was reading about. She connected with other researchers, doctors, biochemists and professors who had similar concerns and has become part of an international effort to help students, consumers and patients understand the science behind nutrition.
Dr. Wendy Pogozelski received her B.S. in Chemistry from Chatham University and her PhD from The John Hopkins University. She was an Office of Naval Research post-doctoral fellow at the Naval Research Lab in Washington, D.C. In 1996, she came to Geneseo where she now holds the rank of Distinguished Teaching Professor and serves as Chair of the Chemistry Department. In her laboratory work, Dr. Pogozelski and her students investigate the effects of radiation on mitochondria. Since developing an interest in the biochemistry of nutrition, Dr. Pogozelski has been working with an international group of scientists and clinicians who are trying to bridge the gulf between scientific research and nutrition education.

I've been fortunate to know Wendy in person as an undergrad. Years later and after completing a medical degree, I still find that her words hold true. A very smart and thoughtful talk like the lectures she would give to us lucky few biochem students years ago. Trust me, she researches into everything she speaks of and has great integrity in the world of research and education.

This was a very interesting talk and a good starting point! A couple of points though that would have increased the validity of her results. I would have liked a mention of the different types of Carbs. We know that not all carbs are the same. Low GI and High GI carbs are metabolized differently in the body and have different effects on blood glucose levels. Also, while positive results for maintaining steady BG levels were shown, we only saw a measurement of one type of effect (BG levels). But many effects should have been monitored. What about fatigue, light headedness during exercise etc. These are symptoms experienced by those on low carb diets and are important to know before we can make an informed decision. Even more importantly, what was eaten? Was it fish, legumes, vegetables? Were major changes made to other aspects of her diet as well? (ie giving up alchohol). How often did she eat during the day? How much exercise was done during the experiment (can a low carb diet sustain an active person)? What about fluids (juice or water??). These are all important variables that significantly change the results of this experiment. All in all, more study are needed but in the meantime we can follow after the speakers good example in listening to advice but also trying different things to find out what works best for you.

That's fine for you to do what works for you, but I just want to say, I've been type 1 diabetic for 24 years and I did the low carb thing in the past, but now I eat a fairly low fat and fairly low carb (basically, everything in the middle) whole foods vegan diet. I tend to avoid grains and white potatoes just because it saves me some insulin, but because I think they're bad or because my sugar will rise uncontrollably (it won't, if I give insulin, I'm fine). My a1c last check was 4.9 (I try to keep my sugars under 100), my good cholesterol was 67, my bad cholesterol was 42. So, yours is not the only way. It's one thing to have good sugars, but I also want to be healthy apart from my sugars. When I ate very low carb and high fat, my insulin resistance was so high that if I ate so much as a small apple, my sugar would shoot up and I'd need, like, 4 units of insulin to cover it. It meant I could NEVER eat carbs anymore, not even fruit. But now that I don't restrict carbs and an not eating so much fat, that same apple only takes 1 unit of insulin, and even if I failed to cover it, my sugar works only rise to about 140.

Type1Vegan Then you do get the point, right? NO one is taking your carbs away, chow down, but you are your OWN study of one….since you don't want this advice for yourself, then at least allow that ALL others may be different from you, and it MAY help them, which is not your issue..you are an outlier.

C. C. Visnesky "you are an outlier" Type1Vegan tried both diets (unlike the speaker) and said that it was the combination of high carb and high fat that reduced insulin sensitivity (given his experience, these effects do not make him an outlier) and that a healthy diet does not only help prevent hyperglycemia but improves overall health, reducing risks of other diseases, too. While he may be an 'outlier' in terms of more experience with exclusionary dieting, he is not an outlier in terms of the fact that both the high fat and low fiber/high carb items or processed carbs contribute to impaired insulin response. Dietary fat also impairs insulin response as it gums up insulin and INS receptors and causes the pancreas to work harder to produce more insulin as blood sugar is elevated. The speaker claims she adopted a low carb diet and then acquired type 1 diabetes. A raw, plant based diet did not cause type 1 diabetes and she is simply managing her condition in a way she has chosen but she did not specify the types of carbs she restricts. Was she limiting bread or blueberries? It turns out both based on her very low plant intake/glucose intake. There are other ways (perhaps more effective than the limited experiences of the speaker) to manage weight, regulate and even improve insulin sensitivity long-term through minimally processed, high fiber diets that are low in cholesterol, heme Fe, and fat and high in antioxidants. Such plant-based diets do not only improve insulin sensitivity but help prevent other diseases of affluence. Snell-Burgeon et al (2009) explain, "Adults with type 1 diabetes reported consuming higher than recommended fat and saturated fat. Fat intake was associated with increased CHD risk factors, worse glycaemic control, and CAC." Elks, Terrebonne, Ingram, and Stephens (2015) confirm blueberry intake reduces metabolic syndrome and improves glucose tolerance. References: Elks, C. M., Terrebonne, J. D., Ingram, D. K. and Stephens, J. M. (2015), Blueberries improve glucose tolerance without altering body composition in obese postmenopausal mice.

Interesting. My diet is about two thirds carbs though (rice crackers, smoothies, bananas, oatmeal etc.), but I do weightlifting 3 times a week. I'd like to see how we respond to highcarb meals, as we have more muscle mass that is more insuline sensitive (compared to our fatcells and compared to the average non-trained joe's insuline sensitivity). I predict this will significantly reduce both size and time of insuline/blood sugar spikes. Also, when you combine carbs with fats, protein and fiber, (basically a balanced meal), the glycemic index can be thrown out the window, as the carbs are absorbed much slower that way. Many studies on glycemic index are done on 1. fasted people (usually not realistic) 2. with the carbs in isolation (usually not realistic). I'm not pro-carb persé. I've done great on a moderate fat+moderate carb diet. Just saying we need to be really careful with going against high carb diets for healthy people. Usually the carbs themselves aren't the problem, it's the crapload of processed foods (that tend to be high -empty- carb) that don't satiate, yet make up a large part of the USA's average diet.

From my research, the best way to handle this is to eat whole food carbohydrates, especially those high in fiber, such as fruits and vegetables, and in excessive quantities. A diet of almost exclusively whole fruits and vegetables ideal. You would be surprised that the glucose release from these foods is slow, and the glucose spike is relatively minor.

+Jonathan Bubb The current belief is that Type 1 diabetes is due to destruction of the insulin producing cells in the pancreas. Most researchers think it is an autoimmune response triggered by virus. While there are people who think nitrites/nitrates in the luncheon meats we put in our kids' sandwiches can cause Type 1 diabetes, it is generally believed that diet is not a factor when someone gets Type 1 diabetes.

the answer for type 1 diabetics though is still eating the required amount of energy in the form of slow releasing carbohyrdates. To eat what is required of the body to function in a healthy way. You are going to take insulin either way. Eating carbohydrate rich foods that are bound to fibre don't cause excessive spikes in blood glucose and are much easier to manage. Eat whole vegetables, whole beans, and whole grains. We run into problems with all forms of processed carbohydrates because it strips away the fibre. Fibre is the key for controlling blood glucose release rate

I am skeptical of the x-axis on her graph at 13:35. If I were doing a Ted Talk I'd want someone to review my Powerpoint for mistakes like that. I also want to know why she's waiting 12 hours between main meals, as suggested by the higher-carb diet blood glucose graph, and not eating anything substantial for lunch. If anything is risky with that kind of diet it would be leaving long periods of time between meals like that. Plus, all the talk "knowledge is power" and "science is best" and then finishing off with one set of results for one person? Sample size, people! This is pre-GCSE level basics, more data makes the experiment more reliable! No, I don't trust this lady. She might be a highly skilled teacher of cell metabolism, and well done for making theoretical teaching practical to students through real-life context... But this doesn't make her an expert in diet, and it certainly doesn't make her a doctor. I'm going to leave my few pinches of salt here...

Dear Jennifer Mitchell, Yours is the only comment I have responded to so far. I detect some sincerity, openness and care even if a few of your comments did cause some pain. The printout from my glucose sensor had an error in one point on the time axis. You have good eyes, It's amazing that no one from the company had noticed it, but this was in the very early days of testing continuous glucose monitors so perhaps that explains it. I was chagrined when I saw it long after having given the talk. I'm not sure why you're saying that I was waiting 12 hours between main meals or not eating anything substantial for lunch. Neither is true. The graphs really don't say anything about what I ate - sometimes the insulin was sufficient to keep blood sugar down; sometimes it wasn't due to the unpredictability of the carbohydrate absorption and insulin absorption. As to your other criticisms, I'd be happy to elaborate. The maximum time for a TEDx talk is 18 minutes which is very limiting. Also, this talk was for an audience of undergraduates - non-scientists, non-clinicians, and non-diabetics, and had to be part of a "Beyond the Blackboard" theme. I kept it simple and oriented toward that audience and theme. If I were giving a talk to the public, or to CDEs or doctors or nutritionists, I'd be much deeper in the literature and yes, citing much bigger studies than N=1. But the idea was that I was to tell a personal story. Actually I had not been told I would be filmed at all and so I had no idea it would appear on youtube, ....to my horror. I might have made some different decisions in retrospect. But it is what it is. Bottom line: As a T1D, I get FAR better blood sugar control with a lower-carb diet than with a higher-carb one. I believe that my decision is supported by my understanding of what we know thus far about human biochemistry as well as many clinical studies in the literature and ultimately, I had to take my own training and experience over what the ADA and ADA-guided dietitian recommended.

There are other important factors in the meal planing, how does she quantify the grams of carbohydrate, what does she call "high carbohydrate"? Was it a high glycemic index diet? Low or moderate? It's not just the amounts od carbohydrates, she needs to be specific about the glycemic load... and, what type of insulin was she using? and the recommended 120 - 130 grams of charbohidrate per day is just a guideline and it has to be adapted to the persons weigh and high and their ideal weight. There are so many other factors and just base ones recommendation and personal experience in a young audience is too simplistic.

The fact that our bodies CONVERT fat and protein INTO glucose should tell you something about what our body prefers and uses most efficiently.

Concentrating on the one or two contributing chemical factors in nutrition without broader context seems very reductive. As much as isolating the 'causal' chemical elements in a given illness seems important, the effects of a range of accompanying ingredients and trace components in a given food, surely, is required to understand the body's reaction to food - particularly whole foods which, biochemically speaking, have a range of trace ingredients that act synergistically with the body's metabolic process. Our bodies are not labs or petri dishes where certain chemical reactions occur in isolation. This approach strikes me (on surface reading, here) as lacking broader contextual and longitudinal data, in vivo, to be appropriate to apply to the complex working environment of a human body over time. There is great work being done on nutrition and population studies out there and great meta analysis is coming out on this and many other modern, nutritional maladies, all the time (just go to www.pubmed.gov or www.nutritionfacts.org). No mention of or reference to any such research here - Why?
@Naniwayuri

+Live-Torsion-Paradox The speaker has done an n=1 experiment on her own body, and is showing us the data. I don't see why you bring up that the body is not a petri dish, or that whole foods confer a wide range of synergistic effects on the body. It seems unnecessary given the nature of the experiment. As to context, I don't see what more you expect from a TedX talk that's restricted to 15 minutes. The immediately relevant context is here: Type 1, insulin dependent diabetic, kept blood sugar low with diet, had it been high, lacking sufficient insulin, she would die. Administering exogenous insulin over a long period of time is not without ill effects, some of which are not fully understood yet. It's as you said, the body isn't a petri dish. It's also very expensive. It also treats a symptom: hyperglycemia. A result of insulin resistance (in type 2, which is 90% of diabetics). Insulin actually deteriorates pancreas beta cell function further. The conventional treatment for diabetes, barring metformin monotherapy, is contributing to its secondary cause. If you want longitudinal studies, they're out there, and you've already linked some good sources. If you want her studies, I'm sure you can find them. She does hold a PhD, after all. If you want youtube commenters to reference studies, well, good luck. Here's one: Conclusion: In people with T2DM, exogenous insulin therapy was associated with an increased risk of diabetes-related complications, cancer, and all-cause mortality. Differences in baseline characteristics between treatment groups should be considered when interpreting these results. - See more at: press.endocrine.org/doi/full/10.1210/jc.2012-3042#sthash.FhnrUhZw.dpuf

Joeri Pelgrims Thanks for the reply. I'm not sure we're on different pages here. My question is; if there are already, broadly evidenced studies, including longitudinal studies that show significant beneficial effects through simple diet change, why start with an exogenous insulin n=1 experiment? Given her PhD level of access, I would have thought it would makes sense to start by exploring the wealth of diet related data, especially considering the associated risks of exogenous insulin over a long period of time. The 'petri dish' comment was simply an acknowledgement of in vivo experiments (over in vitro observations), providing a more comprehensive picture of what is going on in it's proper context - I'm not sure how that might be deemed in anyway odd to point out. If you want to see what can be done in under 15 minutes by way of exposition and referencing for further reading etc. (without getting bogged down) try nutritionfacts.org. It's really very good.

+Live-Torsion-Paradox Yes, I had some difficulty ascertaining your exact meaning. I'm still not sure if I understand fully. Let me try to answer you again. I believe she chose to do this experiment and talk about *it* rather than the things you bring up, to corroborate her point during the talk, which is that your own knowledge is valuable and not to be thoughtlessly dismissed even when you face resistance from an authority. She rightfully qualified this by emphasizing her background in a relevant scientific field. I can only guess as to what she hopes to accomplish. What I hope this leads to: More people choosing to think critically about what they think they know, using the scientific method to do it. What I hope this doesn't lead to: Contrarianism unsupported by reason. I do think she reviewed much of the literature. It would make sense, given her position and interests. She mentions reading "thousands of studies" (but doesn't specify, and I'm sure she meant in her lifetime, not just for this project). I'm still not sure what you're suggesting she should do. Talk about her interpretation of the current literature? People do that all the time, and it isn't very valuable. There is no definitive answer here. When you lay out all of the facts, there are still contradictions, because of incomplete hypotheses. It would be her opinion. It would be interpreted by the public as advice. She ends the talk with a quote stating "When it comes to nutrition, we need more information, not more advice". I agree. To obtain information we need more studies, and better ones. Well funded, well controlled, and well thought out. Too much information in nutrition is still piggybacking on epidemiology. Beyond that, we need to become better, as people, at interpreting these scientific studies ourselves. Because authoritative bodies in nutrition are full of conflict of interest and have a very bad track record. It's become impossible for them to remain up to date on certain topics, because that would mean admitting to past mistakes. Almost like saying "Yeah we may have caused the obesity and diabetes epidemics, but we'll definitely get it right this time". It would harm their credibility, and they won't allow that. They can't be seen dispensing wishy washy advice. They have the information, they just won't do anything with it. They will probably try to backpedal out of the lipid hypothesis so slowly that they figure nobody will notice. Same with their "6 servings of healthy whole grains per day and a shot of insulin" food pyramid that should really be buried with the others.

+Joeri Pelgrims Yes, my point is epistemic. Population studies and in vivo experiments strike me as at least as important as lab work* (*necessary but also necessarily reductive in nature) when applying science to something as complex and subject to contingency as the human body. They seem to be absent from her mode of enquiry. In this way she parallels some of the rather reductive approaches to scientific method and evidence that certain conventional interest in nutrition and pharmacology use to say their products/advice are both safe an effective. Lab work is of great importance BUT not all science is in the lab. I think a broader attitude to scientific method/evidence is overdue, given the track record of an uncritical reliance on the rather isolationist and reductive approach we continue to default and defer to. A falsificationist approach might also be helpful here, if we are to genuinely advocate critical thinking from a position of intellectual honesty.

When information comes forward that does not support this, the inevitable response is that nutrition is very complicated. It's having it both ways, and plenty of us have had enough of the obfuscation and bull from those apparently trying to protect the current paradigm.

This was great right up til she started making recommendations based on a sample size of one with short term results. Low carb can cause depression for a starter - at least based on my sample size of one! The other thing that happens is you wind up getting a greater percentage of calories from fat and protein which can unbalance the body by requiring more bile for digestion. This in turn can alter your gut bacteria and cause other problems. I've messed with my diet enough to know that going for short term results can really screw you. A1c is not your life nor even equated with health.

It's also an open question just how concerned we should be about insulin spikes. Diabetes is much more than a single disease with a single cause and it is foolish to suppose it or treat it as such.

@@SWilkin676, I'm curious to see if you've changed your mind in the last couple of years? It's looking very much like A1c is your life if you care about health and avoiding the complications associated with high average glucose levels (too many glucose spikes). And, diabetes (let's call it insulin resistance) is very much the root of nearly all chronic disease. According to Ivor Cummins, a recent analysis of some 70 diseases found insulin implicated in 67. It is huge but willfully ignored.

I am in testing for Urea cycle disorder. That is likely the reason for my protein problems. My A1c was misleading. I have some sort of digestive problem where my pancreas doesn't make enzymes. If I don't take 3 CREON ($650 a month) a day I don't digest all my food. I didn't realize this and so my blood sugar would go high when I'm digesting food and lower responses to the same foods when I'm not digesting. So the A1c didn't look as bad as my diabetes is. I'm insulin dependant at the moment, will try to get the doctors to figure out what is wrong with pancreas some day. Not everyone has diabetes in the same way, autoimmune runs in my family. I tried to get my nurse practitioner to investigate but as long as my A1c was ok, she didn't see what the problem was.

Its interesting but, she only talk about the low glucose in blud on her low carb diet and completely forgot to check if the brain is afectet by this low carb diet, no study or numbers on this side ? In the book Thinking fast and slow by Daniel Kahneman, I remember a study showing that the brain is less lasy to do high effort thinking when people have eaten carbs. Here I find it : The nervous system consumes more glucose than most other parts of the body, and effortful mental activity appears to be especially expensive in the currency of glucose. When you are actively involved in difficult cognitive reasoning or engaged in a task that requires self-control, your blood glucose level drops. The effect is analogous to a runner who draws down glucose stored in her muscles during a sprint. The bold implication of this idea is that the effects of ego depletion could be undone by ingesting glucose, and Baumeister and his colleagues have confirmed this hypothesis in several experiments. Volunteers in one of their studies watched a short silent film of a woman being interviewed and were asked to interpret her body language. While they were performing the task, a series of words crossed the screen in slow succession. The participants were specifically instructed to ignore the words, and if they found their attention drawn away they had to refocus the concentration on the woman’s behavior. This act of self-control was known to cause ego depletion. All the volunteers drank some lemonade before participating in a second task. The lemonade was sweetened with glucose for half of them and with Splenda for the others. Then all participants were given a task in which they needed to overcome an intuitive response to get the correct answer. Intuitive errors are normally much more frequent among ego-depleted people, and the drinkers of Splenda showed the expected depletion effect. On the other hand, the glucose drinkers were not depleted. Restoring the level of available sugar in the brain had prevented the deterioration of performance. It will take some time and much further research to establish whether the tasks that cause glucose-depletion also cause the momentary arousal that is reflected in increases of pupil size and heart rate.”

Teedjay Gendron The brain can run on ketones which are elevated when diets are low in carbs (>50g/day) though there appears to be a period of adaption required to transition from a predominantly carb to fat as energy source. However, once this period is over, I don't think it would be an issue. Would make for an interesting research if anyone could find funding for it. As a N=1 experiment, in periods when I am VLC I seem to have much better mental clarity and less fluctuations in energy.

Dr Pogozelski approach to treating Diabetes is not new. In fact, ages ago it was recommended that the only treatment for Diabetes (both Type 1 and 2) is to complete omit all or majority carbohydrates from your diet. But Carbohydrates play a role in our diet. This is a area that the she does not tackle. On a very basic level, carbohydrates are your body’s main source of energy. They help fuel your brain, kidneys, heart, muscles and central nervous system. Eating foods high in CHO are part of a healthy meal. Imagine omitting or eating low amounts of CHO/ high fiber foods such as peas, yam and corn and even fruits. In addition to providing CHO these types of food provide other nutrients, that once limited in the diet can affect you in other ways... Perhaps she should have discussed any effects she would have had from this diet such as constipation. Food is to be enjoyed, and this approach is in line with this idea that we should deprive ourselves of food to be healthy. This is not so. Eating adequate amount of CHO, eating healthy, exercise and being on a individualized insulin regime can allow anyone to live a normal life without being on a 'low carb' diet.

I'm just saying, if she is promoting the ketogenic diet, doesn't this promote Diabetic Ketoacidosis? (probably also explains the limit given by the ADA on the 130g of carbohydrates)

+dannijonesXD Lets talk. There are nutrients and there are calories. Nutrient dense foods include meat, nuts, dark greens, and berries. All of these are embraced in low-carb diets (berries are a fruit comparably low in sugar). Carbohydrates such as wheat, rice, and starches are not as nutrient dense. Fats are not normally nutrient dense, if I recall. Caloric intake is manageable on either diet. Many people like low-carb because even if a person is not diabetic, the insulin rise after a carby meal will rush a good portion of what was just eaten into fat and simultaneously prevent the body from using fat as energy. Reducing the amount of carbs eaten will eliminate this effect. I am not sure if you meant calories when asking if more protein and fat is necessary. It is. Meals include more cheese, cream, and eggs. People who reduce their sugar consumption stop having cravings and their taste changes to not like sweet things as much. One lady who is raising her kids low carb says they will go for beets like other kids go for candy. Ketoacidosis is more than ten times the intensity of a dietary ketogenic diet. It is impossible to reach ketoacidosis through even the sloppiest keto diet unless there is a medical issue which would cause ketoacidosis, anyway. There is tons of info out there from serious people, if you want to know more. I recommend checking out wikipedia and www.reddit.com/r/keto look at the right side of the page for more links.

Patrick Kniesler I would argue that starches such a sweet potato are more nutrient dense than meat. They also offer more complete nutrition. Meat isn't all that nutrient dense after all. Cheese is among the most acid forming foods out there. I think Danni is right to question things when there's such a lack of evidence. I would recommend to not blindly believe anyone unless their sources are clear. Fad diets such as the keto diet and the paleo diets will offer little but a ticket on the hype train. If people are sensitive to authority figures more so than scientific evidence, I'd say listen to Einstein.

Siegfried Furtwängler Knappertsbusch did you just say sweet potatoes offer more complete nutrition than sweet potatoes? Are you taking into account proteins? Are you measuring this by ratio of nutrients to mass or calories - doesn't matter meat has it beat. You do know that it is possible to live on meat and water, alone, right? Many people on keto eventually try not eating cheese or cutting all dairy. Also I am not just parroting this. I feel better and am a better weight since I started incorporating low carb into my life. I read the studies and articles. Look around, you'll see articles in every major publication questioning the Standard American Diet.

So she's been a "biochemistry professor and had been teaching about biochemistry a long time" but didn't see anything wrong with her diet beforehand until she got diabetes? How can she be a professor and the title of this video be "How Knowledge is Power in Nutrition" if she didn't even know her diet was leading her to diabetes until she actually got the disease? If she truly had the knowledge previously, she wouldn't have made this video because she would have prevented herself from getting diabetes in the first place. At 8:36 she says: "In type 2 diabetes, insulin is present, but the downstream reactions are affected in some way". So basically she has no idea what causes insulin resistance. She's a professor and the video is titled "How Knowledge is Power..." and yet no new information is given- just a general video on how low carb normalized her blood glucose (she didn't say if she was cured of diabetes or not). I wish people would stop putting out more of the same simplified information we already know. Some high carb vegan gurus would argue that dietary fat is what "gums" up the receptor at the cell site which leads to insulin not working properly. I want to know if THAT theory has any validity. We need real answers, not more people making videos who don't really have extensive knowledge on the topic.

+Joshua Erny So sad that people like you are allowed to post on the internet. She has Type 1 diabetes. That means she suffers from an auto-immune disorder. The beta cells in her pancreas have been destroyed by her own immune system. It takes approximately 1 minute to learn this from googling. That means her diet had nothing to do with her situation. And she's again, absolutely correct about type 2 diabetes. With type 2, your body produces plenty of insulin, but your receptors for insulin don't function properly. Maybe we should listened to qualified people like Dr. Pogozelski and not random vegans on the internet. Yes, we all know you're a vegan and your attempt to imitate a normal person has failed completely. Unfortunately, like all vegans, your incredible ignorance when it comes to physiology and biochemistry gave you away. Nobody but vegans pretend to be experts while being so incredibly ill-informed.

+Joshua Erny She has Type 1 diabetes which is some kind of inflammation/immune process that killed the beta cells on the pancreas. Diet has nothing to do with it. Experts frequently dumb things down for lay people. That doesn't mean they don't know the stuff they gloss over. People are not cured of diabetes whether they are low carb or high carb. They may or may not need medication to maintain normal blood sugar but they have impaired response to glucose. They are told to keep blood sugar as even as possible and the question becomes which lifestyle does that the best. Ask any guru to put up what she did - an hourly chart of blood glucose. If your goal is to pick the diet/lifestyle that gives you the steadiest glucose, you'll see which is best. Or you can do as she did and test it on yourself. That is what n=1 means. This is why she said, this works for me, after displaying her chart.

My Thoughts, Here's why vegans have to take B12 in supplement form: B12 is actually found in soil. This is where animals get it from. Early humans use to get B12 from vegetables that had soil on them and from free flowing water. Today we wash our vegetables and treat our water, so the B12 is lost during that process. Considering all the benefits that are associated with a vegan diet (lower incidences of heart disease, and cancer, reducing animal suffering and reducing contribution to global warming), taking a b12 supplement is not a big deal at all. As for Omega 3s, there is a minority of people whose bodies aren't good at absorbing/converting plant based omega 3, so that is the reason why Dr. Greger recommends taking a Omega 3 supplement. It's only for people who want to be on the ultra safe side just in case they have the body type which is not good at converting ALA to DHA. What I want to point out to you though is that countless doctors also recommend Omega 3 supplements to meat eaters! The reason is because it helps prevent brain degenerative diseases and most meat eaters are not getting enough. Meat eaters would have to eat a lot of fish every week to reach optimal DHA levels, fish which is coming from our highly polluted oceans. Heavy metals in the water get absorbed by the flesh of the fish that people are eating, so whether you are a vegan or meat eater, it appears that we should all be getting our omega 3/DHA in supplement form.

Nick TT Vegans are so funny, they always repeat the lies their high-priests tell them. No society has ever been vegan, so the idea that humans got b12 from plants is a silly post-hoc conclusion made from faulty vegan logic. The logic goes like this: "A vegan diet is the best diet in the world. The best diet in the world would include b12. We know that b12 that humans can use is only found in animals. Therefore, at some time in recent past, humans did something that stopped them from getting b12 from plants." A normal person sees the mental gymnastics going on there and says "Wow, that takes some mighty strong faith to convince yourself of something that's obviously wrong." It's like saying "I know the sun revolves around the Earth. Modern scientists say the earth revolves around the sun. Therefore, something changed recently and now the earth revolves around the sun and it used to revolve around the earth." As for a vegan diet saving the planet and improving one's health, both take a huge amount of faith not backed by facts. Vegans tend to exercise, don't smoke, don't drink, don't eat processed food (sugar, flour, etc), see the doctor regularly, make a host of health conscious decisions, and don't eat animal products. They then compare themselves to the standard American who smokes, drinks, doesn't exercise, eats ice-cream and cake all day, does nothing to promote their health, and eat animal products. Lo and behold, the vegans are healthier. However, when you compare people on a vegan diet with people who eat animal products, yet exercise, don't smoke, don't drink, don't eat junk food/processed foods, and make health conscious decisions, they are as healthy or healthier than vegans. This is why vegans don't like clinical studies. When all variables are taken into account, animal products are found to be healthy and cause no disease. As for the environment, a lot of animals died for you to eat that kale. Lots of fossil fuels were needed to fertilize, grow, protect, and transport those veggies. When you're eating blue berries grown 1,000 miles away, and broccoli grown 2,000 miles away, you aren't helping the planet. The idea that raising live-stock is worse for the environment has never been shown by people who aren't biased in favor of a vegan life-style. If you are vegan because you believe meat is murder, then keep it up. If you are vegan for health or environmental reasons, then you have been conned. There is no benefit to going vegan. There are lots of benefits from eating animal products combined with veggies. So if it's not about morality, then you've been lied to.
