Don't eat fats!
In the 1950s this was the message that resounded in our homes and offices. Ancel Keyes, a physiologist, informed the world that dietary fat was responsible for clogging arteries. His landmark study found that people who ate a diet low in saturated fat had a lower incidence of heart disease than those in western countries who ate a fat heavy diet.
Keyes stated that Americans must reduce the fat calories in their diets by a third if they wanted to avoid heart disease. Reducing fat calories also seemed to make sense for weight control since fat contains more calories per gram than protein or carbohydrates. It seemed to make sense that if you reduced the fat calories in your diet you would not only lose weight but would also minimize the possibility of developing heart disease.
Even though his research and conclusions were flawed, his message went mainstream and became imbedded in modern medicine and nutrition. Almost all of us drank less whole milk. eat less beef. fewer eggs and replaced butter with margarine.
How has this changed? That will be discussed in future blogs.
