Transcript for New study suggests plant-based diets reduce risk of heart disease
We turn to the new study on plant proteins and long-term health benefits. Could uping your intake of bean, nuts and more help prevent heart disease? Dr. Ashton will join us with more on that. Tell us about the study. So, robin, here it is. It was just out in the journal of the American heart association, pretty big study, over 100,000 postmenopausal women were followed then for 18 years and the findings of this study pretty interesting. They found that the women who ate more protein from plant-based sources had an associated lower risk of dementia, lower risk of heart disease and lower risk of something we call all cause mortality means death from all causes, in comparison to people who ate more red meat, dairy, eggs and powellry. Animal protein. So do researchers know why that is? There's some working theories that have been reported in the medical and nutritional science literature. One has to do with inflammatory metabolites so these are by-products of animal protein that can then affect the heart and the brain and our blood vessels, another one has to do with the gut mfrment icrobome. Those are the two main working theories at this point. Jen, word on the street you're three weeks into a plant-based style of eating. How is it going? I am, robin. This was my little experiment during my last covid quarantine and I'm about three weeks in, just curious whether or not I could do it. Whether I would notice any difference. I've been completely plant-based pretty much for the last three weeks. I checked my bad cholesterol. It dropped after just ten days of eating this way from 111 to 85. I measured my body composition, I lost 2% body fat. My weight stayed the same and I lost one point off that dangerous internal visceral fat so even someone doing this just one or two days a week could potentially have some health benefits. What is your advice to -- if I want to give this a try. Dip your toe in the water. It doesn't have to be all or you could start with just one day of plant-based eating then maybe that will lead to two but, listen, if I can do it, anyone can do it. Okay, I'm going to go with a meatless Monday. Meatless Monday but Tuesday, Wednesday, Thursday, Friday -- she said just a start.
