To Eat or not to Eat Carbs or Fat: That is the Question

Dr. Walter Willett, of the Harvard School of Public Health, has composed a new food pyramid–and it does not match the one that we all learned about in school. For over 30 years we have been told to cut fat and increase our intake of carbohydrates. The result is an epidemic in obesity, heart disease and Type II diabetes.

Now, increasing evidence shows that effectively reversing the two bottom layers of the traditional pyramid may result in weight loss, reduced cancer risk, and many other health benefits. Basically, we are healthiest when we major on eating fruits, vegetables, and unprocessed grains.

Scientific knowledge changed. It seems that the “experts” were wrong, not as a result of dishonesty, but just as a consequence of the fact that science does not have all the answers. Science is said to be self-correcting, which means that it is sometimes wrong. Therefore, we should remember this simple example the next time we are tempted to abdicate our very important responsibility to think and weigh the evidence to the “experts”.
