How Knowledge is Power in Nutrition | Dr. Wendy Pogozelski | TEDxSUNYGeneseo

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.

  1. Everyone is different in how many carbs to eat per meal.I was diagnosed with LADA, and right away I went to diabetic classes and they were geared more on type 2 diabetics so I cut my carbs a lot and lost a lot of weight. I am now eating about 45 carbs per meal on a insulin pump and my weight is great so everyone is different…I recommend a heart healthy diet.

  2. I’m curious about her overall health, though. Ok, her blood glucose is low, but what about her metabolic processes? Is she able to use enough glucose to ‘make energy’ and remain healthy?

  3. What light she provides in the darkness of a corrupt food and medical-advice providing supply chain. Why it is difficult to believe that people who cannot process carbohydrate should probably not eat carbohydrate is testament to the power of such a corrupt, self-centered, patient-hostile, pharm-biased health unprofessional industry. Some things are changing and this speaker is helping to lead the way. Highly recommended viewing.

  4. 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…

  5. I know it was probably just a simple slip up but I couldn’t keep watching after she incorrectly called the x-axis the y-axis

  6. I’d love to hear more from Dr. Wendy Pogozelski. The students at SUNY Geneseo are lucky to have her!

  7. haha vegan whole foods diet including all the fruit, whole grains has proved to reverse diabeties, cancer look at the chanel

  8. It’s the refined grains that are very bad, not the organic, unrefined grains. For instance, bagels should be considered hazardous bio-weapons and waste

  9. 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

  10. Cancer patients? Guess what, the same thing works to prevent cancer and and reduce tumor size – a low carb, non-glucose-inducing, non-insulinogenic diet. Most cancers will start shrinking. This works a whole lot better than chemo drugs. Yeah, the medical establishment doesn’t want you knowing that cancer, like diabetes, can be controlled with diet.

  11. thats why liver gives brain glucose from stored glycogen …..fruit fructose bypasses insulin like in RAW honey glucose/fruvtose
    Glut transporters!!

  12. Carbs can be natural or processed. Preparing carb meal is another issue for example French fries loaded with unhealthy salt and oils versus boiled potatoes will not have same effect. Raw Plant based Whole Foods are awesome and can heal diabetes. Check out Dr. John McDougall, Dr. Joel Furhman, Dr. Bernard

  13. Very interesting talk, particularly the connections between insulin, hemoglobin, oxygen delivery, and kidney function. My dad is a diabetic and liver-kidney transplant recipient, so these insights are helpful.

  14. Thank you. More info and less advice. The FDA sucks. They are not doing their job in protecting us. You did right Ms. Do your own study and take care of yourself because the FDA WON’T.

  15. she should investigate the benefits of the whole foods vegan diet, and you are really really wrong if you compare the spike in blood sugar from white rice and pasta to that of fruit:/

  16. Talking about carbs in such a general way is unlikely to enhance knowledge about nutrition. No gold star from me for that

  17. I watched 300 hours of you tube vids where drs. MacDougall, Fuhrman, Ornish, and a dozen others use a HIGH CARB, plant based plan to REVERSE diabetes. I could not see where your ADVICE had any basis in science.

  18. Processed and unprocessed carbs are two entirely different worlds. Disingenuous to say "all carbs" when it’s actually only processed carbs that have this kind of reaction.

  19. 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.

  20. Dr. Neal Bernard has laid out the benefits of a whole food vegan diet in reducing insulin intake on type 1 diabetics and totally eliminating insulin need for type 2 diabetes. might wanna look up some of his YouTube videos where he goes into some of the science behind this

  21. Five weeks is not long enough to draw a significant conclusion. Yourself study is bias as you new what diet you where on each time.

  22. +Dark-sheep13 you are 100% spot on and by far the most accurate comment on here.. can’t believe this BS is still crippling today’s perception of what true evidence-based nutrition really is. This quack should be put behind bars!

  23. I am surprised that Dr. Pogozelski didn’t mention Dr. Richard K. Bernstein who has been working to promote the low carb diet for type I and II diabetic patients for decades.

  24. 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.

  25. 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.

  26. Uy, this woman got me anxious in the first minute, maybe she has good information but I will skip this video…

  27. Yes, you can do this. It is close to or is the ketogenic diet. I don’t think it is ideal at all. Instead if you have trouble measuring your insulin I suggest eating the same thing every day at the same time and making it primarily based on starch like japonica rice.

  28. 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.
