A large new study from Harvard University suggests that daily administration of small doses of olive oil may significantly reduce the risk of premature death. It raises questions among all food and plant-based eaters, as avoiding the addition of oil is the basis of the WFPB diet.
new studyPublished in January Journal of American College of Cardiology, We used data collected from more than 90,000 healthcare professionals over 28 years to determine olive oil consumption and mortality. There are 60,582 females in the nurse health survey and 31,801 males in the medical professional follow-up survey.

Participants answered the health assessment questionnaire every two years. They complete a detailed food frequency questionnaire every four years, asking how often they averaged certain foods in the previous year, such as the type and brand of fats and oils used in cooking and added to the table. I did. During the 28-year follow-up period, 36,856 participants died.
After adjusting for known risk factors and other dietary factors, researchers found that participants who consumed more than half a tablespoon of olive oil were 19% less likely to die of cardiovascular disease or any other cause. Did. They are 29% less likely to die of neurodegenerative diseases such as Alzheimer’s disease, 17% less likely to die of cancer, and respiratory illnesses compared to people who consume no or little olive oil. 18% less likely to die in.
“Our findings confirm current dietary recommendations for replacing animal fats with vegetable oils to prevent chronic illness and premature death,” said Malta, the lead author of the study. increase. Guasch-FerréSenior Research Scientist, Faculty of Nutrition, Harvard School of Public Health.
So is oil healthy now?
An important point for WFPB eaters is that a Harvard study analyzed mortality based on the different types of fat added to the diet. They did not explore the benefits of a diet with little or no oil.Neal Barnard, MD addressed the question in the January 20th episode Laboratory By the Medical Committee Podcast..
“Olive oil teeth Better than chicken fat, beef fat, cheese fat and dairy fat. It’s better than all of this, “said Bernard, chairman of the Medical Association for Responsible Medical Care. Laboratory Host Chuck Carroll. “Chicken fat is 30 percent saturated fat. Beef is 50 percent saturated fat. But for olive oil it is up to 14. [percent].. that’s good. ”
Then Bernard issued a big warning. “But what if you get a non-stick pot instead and don’t use any fat? Every gram of fat is 9 calories, no matter where it comes from, our study. It’s the best of all, as it generally shows that when people get away from these fats, they do their best above all else. So Olive Oil: Absolutely Better Than Animal Fats Slam dunk. But learning to really minimize oil, even olive oil, is probably the best way to go, “he said.
“Researchers have tried to claim that olive oil is magical, and like broccoli and sweet potatoes, it has a variety of botanical ingredients. But the big problem is that you’re already animal fat. I think I haven’t eaten, “Bernard added.
In fact, a new study found that replacing butter, mayonnaise, or milk fat with olive oil reduced the risk of overall mortality and causal mortality, but replacing olive oil with other vegetable oils. , No significant reduction in risk was seen.
The authors of the study also noted that participants with high olive oil intake tended to be more active and less likely to smoke than other participants. They also consumed more fruits and vegetables than people who ate little or no olive oil.
WFPB proceedings against oil
“There is no doubt that removing all other fats will reduce the harm of one unsaturated olive oil, but the main points are: What we are really striving for in cardiovascular disease is to eliminate it. If that is the case, there is no 18-19% risk reduction, “said Coldwell Ethelstin, a pioneer in lifestyle medicine. Prevention and reversal of heart disease..
“When did Harvard University conduct a petroleum study to see a patient with a serious heart disease and arrest and restore it? That’s what we were able to achieve, [Dr. Dean] Ornish and others who follow this kind of approach, “said Esselstyn.
and 2014 research Family practice journal, Esselstyn et al. Tested a plant-based diet for all foods in 198 volunteer patients with established cardiovascular disease. Of the 177 patients (89 percent) who responded to intensive counseling and continued their diet for an average of 3.7 years, only one had a major cardiovascular event: stroke. Meanwhile, 13 of the 21 patients who did not stick to their diet experienced adverse cardiac events.
2019, Esselstyn Editorial International Journal of Disease Reversal and Prevention Summary of a series of studies showing that oil consumption promotes vascular injury, including studies Published in 2000 We investigated the postprandial effect of olive oil on the endothelium, a membrane that covers the heart and blood vessels and helps control the relaxation and contraction of blood vessels. Studies have found that a diet cooked with olive oil reduces flow-mediated expansion. Measurement of arterial blood flow, 31 percent.
Another concern when adding oil is its calorie density and ability to promote binge eating and weight gain.
For 4,000 calories per pound, “oil follows essentially the same model as processed sugar squeezed from plants,” explains Alona Pulde, MD and Matthew Lederman, MD. Forks over knife plan.. “Think about what oil is. It’s fat, and nothing more than fat …. Any kind of oil has more calories per gram than any other food we know. And without fiber or water, the oil lacks the bulk to convey the number of calories you ate to your senses. This is the fact that your diet consumes more calories than you need. Guaranteed on. “
