So, it turns out that a low-fat diet (you know the kind where you justify eating no fat Oreos or Entenmann’s chocolate chip cookies) isn’t going to help you lose weight or more importantly, prevent cancer. This is the kind of “we moms knew that already” stuff I love! A team of Harvard researchers followed 49,000 women for eight years and tracked their health as they ate a low fat diet. The women lowered their fat intake from 38% of their daily calories to 20%. After eight years, the researchers looked at how many (and what percentage) of women in each group had developed breast cancer or colorectal cancer. They tallied up heart attacks, strokes, and other forms of heart disease. They also looked at things like weight gain or loss, cholesterol levels, and other measures of health. The low fat diet showed no difference.
