New research from Harvard’s School of Public Health offers a fresh perspective on eating fats and suggests replacing dietary fats, such as butter and oil, with more carbohydrates isn’t the heart-healthiest choice.
In the 1970s, certain fats were portrayed as dietary bad guys as mounting research suggested they were linked to cholesterol, a risk factor for heart disease, New York City internist Dr. Alexandra Sowa told CBS News.
“So we started doing everything low-fat. Now we realize that there are two different types of fats, saturated fats that come from animal products — dairy,meats — and when we eat them in excess, they can be linked to cholesterol,” said Sowa, who was not involved with the study. “There is another sort of fat, unsaturated fat, that we find in avocados, nuts, and certain oils that can actually be cardio-protective and good for your brain.”
