Listen: Over processed foods add 500 calories to your diet every day
"Their new diet studies out this week and they add more evidence that when it comes to staying healthy. It may not be enough to just count. Those calories what you choose to eat really does matter in pairs Rb reports on what researchers learned when they tracked the diets and health of thousands of women over two decades when the women's health initiative study began back in the nineteen nineties about twenty thousand women were put on a diet. They were told to cut back on fatty foods such as red meat and full fat, dairy, and they were told to add in more plant based foods, here study, author Rowena Boesky of the Los Angeles biomedical research institute at harbor UCLA medical center, but we ask them women to eat more fruits vegetables, and grains, but also to reduce their total. Fat intake, two decades later, what he and his colleagues have found is that women who were put on this diet at twenty one percent lower risk of death from breast cancer. Compared to women who didn't change their diets. This is significant because this is the first intervention study at anytime targeting breast cancer, where reduction in deaths from breast cancer has been seeing this study adds to the evidence that what you eat can be an important driver of health, but it also raises new questions about exactly which changes the women in the study made that may have been most beneficial. Here's Jennifer Liga belt a medical oncologist at Dana Farber Cancer Institute, there's been a walk that we've learned in the time since the study started about healthy fat, and unhealthy fat at a time when we're told to eat, plenty of healthy fats sources such as KADO 's and olive oil. Was it really an overall reduction in fat during the study that worked in the women's favor? Or was it due to other factors such as all of the good, nutrients and fiber that come from eating more fruits, vegetables, and whole, grains, Schabowski says it's just not clear. We can't really separate out at the present time. Which component was important. But we have blood on all forty eight thousand women, and now we will be a number of analyses to see if we can dissect out which were the important components. So there's much more to learn now. One interesting point, the women in the study were not told to count calories or reduce calories, but overall, they did lose weight. We didn't target caloric intake reduction, but the women did reduce their weight by about three percents. I think it's a message of dietary moderation the signings fit with another new study out this week that evaluated the effects of an ultra process diet compared to minimally processed diet it to finds that an overall healthy diet containing plenty of fruits vegetables, and whole grains can help prevent weight gain Darya schmo, Zafar, Ian is dean of the Friedman school of nutrition at Tufts University. The effects are really consistent with a lot of research coming out, over the last decade that you can't judge a food by its calorie count. And when it comes to eating healthy the quality. And range of foods, you choose matter"
