I had heard this on the news back in March, but didn't follow up
and read it until now. A new meta-study found no evidence of an association between saturated fat intake and CHD and stroke. They did find an association of CHD, diabetes, with the intake of refined carbs though....... http://www.scientificamerican.com/ar...cardio/?page=1 http://well.blogs.nytimes.com/2014/0...ype=blogs&_r=0 There is speculation whether the USDA will now change their dietary guidelines. Sadly, I doubt it. It also doesn't seem to have had any impact on the American Heart Association: http://blog.heart.org/study-raises-q...-and-bad-fats/ "The American Heart Association is concerned that the study's conclusion could be deceptive for some people as they decide what to put on their plates.. "You might think, 'I guess I don't need to worry about saturated fat,' and that's not true," said Linda Van Horn, a registered dietitian and professor of preventive medicine at Northwestern University's Feinberg School of Medicine." "This research simply means that we lack the data from controlled clinical trials that truly test this question of how much saturated fat is acceptable, so we must rely on existing science that suggests that saturated fat is atherogenic, meaning it tends to promote the formation of fatty plaques in the arteries," said Van Horn, who is also a volunteer for the American Heart Association." The AHA and ADA have screwed folks for years with their campaigns against fat, which flooded us with products that were low fat, but full of refined carbs. You can see the results in the obesity and diabetes epidemic. And both are still at it. Another recent study compared obese people with diabetes on the ADA recommended low fat, high carb diet versus those on a low carb, high fat diet: http://healthimpactnews.com/2014/stu...nic-diet-wins/ A new study published recently (April 2014) compared two diets with overweight diabetic people. One group ate the standard recommended diet by the American Diabetes Association, which was a low-fat, high carbohydrate, restricted calorie diet, as per the USDA dietary guidelines for a "healthy" diet. This group was assigned a "registered dietician with several years of diabetes education experience." The group was encouraged to eat a diet that was 45-50% carbohydrates, while restricting calories and fats. As per the study: "the diet includes high-fiber foods (such as vegetables, fruits, whole grains, and legumes), low-fat dairy products, fresh fish, and foods low in saturated fat." The other group, almost in direct contrast to the ADA diet, was encouraged to eat a a very low carbohydrate, high fat, non calorie-restricted ketogenic diet. Their goal was to reach a state of "ketosis," defined as a blood beta-hydroxybutyrate level between 0.5 and 3 mM, as measured twice a week at home using blood ketone test strips. The ADA diet group, despite eating far fewer calories per day than the ketogenic diet group, did not lose as much weight as the ketogenic diet group. The ADA group lost an average of 5.7 lbs., while the ketogenic diet group lost an average of 12.1 lbs. In terms of diabetic medication, the results were also quite different. 7 out of 11 ketogenic dieters (64%) were able to reduce their anti-diabetic medications, whereas only 2 out of 13 ADA dieters did (15%). |
