It takes approxinately 44 olives to make 1 Tablespoon of olive oil. So in this study, the olive oil eaters would have consumed the equivalent of 160 whole olives. No one would consume that many olives in a day. Just eat a few whole olives, not olive oil.
-
It's really important to note that the participants in this study were OBESE (average BMI of 32) and more than half of them were on statins and blood pressure meds. Both of the vegan diets were quite high in fat, and the EVOO group were consuming 400 calories MORE per day than the no-oil group. Also the "good" HDL dropped dramatically in the no oil group. Nothing in this study suggests there is any reason to reduce intake of EVOO in people who are not overweight and do not have high cholesterol.

I follow a lot of podcasts and they are hit or miss. Sometimes I listen, other times I miss them. With Chuck and Dr Barnard I am always going to listen - I learn a lot, respect them entirely and find them so very easy and pleasant. Vegan for about 15 years now and always tweaking with new studies and data which are presented so well. Would love to hear more about diets and changes needed for those of us in their 70s and beyond. Nutritional needs change.

Doctor Barnard, Chuck, and the PCRM are a treasure. So few Doctors and organizations trying to actually help the health of people. Most healthcare providers don't know how and don't care to learn how. Whole Food Plant Based Vegan of 7 years. So thankful for all the vegans who suffer attacks to get the word out. It cured my diabetes, heart disease, and obesity.
-
I think Dr Barnard underestimates how many nuts I can stuff myself with 😅
-
Could we focus a bit on weight gain too? If nuts are mostly bad because of weight gain, I want them, but concern for people who want to gain weight seems lacking here.
-
Dr Esselstein said oil is oil no matter what don’t eat it! He was a renowned cardiovascular surgeon in Cleveland clinic and specialty in heart surgery. He live in a farm with his parents growing up eating american diet and he do not recommend milk to eat from a cow farming family till he becomes a surgeon and conduct biggest research in asia for people eating meat and consuming oil. To whom you would listens?? Back up by research and surgery expert.
-
The seed oil folk are waging a bit of a war on olive oil. I strongly advise watching Zoe's recent in depth video on olive oil. It's more believable.
-
Dr. Gundry is going to be pissed!
-
The EPIC-OXFORD STUDY, part of the European Prospective Investigation into Cancer and Nutrition, examined the diets and health outcomes of over 65,000 participants. It found that vegetarians had a significantly lower risk of coronary heart disease compared to meat-eaters.
-
Google the EPIC study. In Spain the participants who ate only pure EVOO (which is not mixed with seed oils) showed decreased risk of coronary heart disease as well as all cause cardiovascular mortality. They also did the study on a group of Italians post MI.

these livestream videos are always fun! I always look forward to them in the morning when they appear - they really brighten my day - the interactions, the flurry of the live chat. It's just fun to watch the video and engage in the comments section at the same time - so much for my brain to participate in - I love it!
-
IF saturated fat is so bad for us, please explain how those promoting the carnivore diet, mainly Dr Ken Berry (PHD), Dr Philip Ovadia (cardio surgeon) and Dr Jordan Peterson, among others, are having great blood work results, reversing chronic conditions like diabetes, and maintaining healthy outcomes??
-
Circa minute 32:00, the obvious solution is to avoid SALTED or SWEETENED or ROASTED nuts and seeds (and any other such foods generally). If you eat raw nuts and seeds and chew well, you will find that you become satiated quickly. You have to chew thoroughly to get the most nutritional value from real whole foods. The longer that you spend chewing, the faster you become satisfied with less. Double win!
-
The good doctor never once mentioned the effect of blood cholesterol on life expectancy or even rates of heart disease or stroke.
-
You've emphasized the importance of limiting fats, present in highly caloric oils as well as in nuts, in dairy, etc. You've mentioned that oils and fats affect heart health, by increasing cholesterol and BP. All that having been said, please address the role of fats vis-a-vis brain health and tell us the healthiest fats and diet for the brain. Thank you.
-
Thank you Chuck, Dr Barnard & PCRM. I appreciate your analysis re: diets. Love your fashion sense Chuck!

I"m 75, vegan for over a year, no oil of any type. My only vice is peanut butter....I eat 3 tbsp daily. If I didn't spread it on my snack of Ezekiel bread slice or Wasa cracker I would blow away: I don't need to lose another ounce of weight. I eat 1 1/2 cups black beans daily, two half cup servings of oatmeal daily with walnuts and flaxseeds, the higher density plant foods. Don't know how else to add enough calories from plant food to maintain weight.
-
Thats strange because I went keto and then to carnivore with lots of sat fat and my cholesterol actually went down. When I tried the vegan diet for 9 months my body was inflammation and I felt like shit. So much that i quit after 9 months. I had a steak that same day and it felt like I was reborn. As for your comment about mother nature, she didnt make any of the fruit or vegetables that we all eat today. Man created nearly all of it. Not to mention its seasonal.

I have been doing the 0 fat diet for 2 months now, I'm 54 years old and I feel and look amazing. I started on the starch solution way of eating which changed my life
