For the last 60 years, we have been told by the powers that be — including the Academy of Nutrition and Dietetics, the American Heart Association, the American Diabetes Association, and the U.S. Department of Agriculture — that we had to lower our fat intake.

We were promised that lowering fat intake, particularly animal fat, would lower our risks for obesity, heart disease, and cancer, and that this low-fat diet would make us healthier.

As a society, we have significantly lowered our fat intake in the last six decades.

Furthermore, we replaced saturated fat with plant sources of polyunsaturated fats such as margarine and soy, corn, and canola oil.

What have been the consequences of making these changes? We are now the most obese people to ever roam the face of the earth.

At present, two-thirds of Americans are overweight, and one-third are obese.

In addition, we have more cases of diabetes than ever before, cancer rates are rising to epidemic levels, and heart disease is our number one killer.

Clearly, the dietary changes we made have not helped our overall health.
