Uncertain science should no longer guide our nutrition policy. Indeed, cutting fat and cholesterol, as Americans have conscientiously done, may have even worsened our health. In clearing our plates of meat, eggs and cheese (fat and protein), we ate more grains, pasta and starchy vegetables (carbohydrates). Over the past 50 years, we cut fat intake by 25 percent and increased carbohydrates by more than 30 percent, according to a new analysis of government data. Yet recent science has increasingly shown that a high-carb diet rich in sugar and refined grains increases the risk of obesity, diabetes and heart disease — much more so than a diet high in fat and cholesterol.
It’s not that health authorities weren’t warned. “They are not acting on the basis of scientific evidence, but on the basis of a plausible but untested idea,” Dr. Edward H. Ahrens Jr., a top specialist at Rockefeller University and prominent critic of the growing doctrine on dietary fats and cholesterol, cautioned back in the ’80s. In the face of urgent pressure to offer a solution to the rising tide of heart disease, however, he turned out to be the Cassandra of his day.
