Public health guidelines, such as the
Dietary Guidelines for Americans, have long emphasized reducing dietary fat intake, but nutritionists and other health scientists now have more recent evidence that not all fats have adverse effects. Dietary fats differ with regard to their effects on health and risk for chronic diseases, particularly in regard to effects on risk for heart disease.
Indeed,
some nutrition experts now believe that certain types of dietary fat may even reduce cardiovascular risk. Some dietary fats may lower fats in the blood called
triglycerides. They may also increase levels of HDL, or what is known as the "good" cholesterol, and
reduce LDL-cholesterol, or the less healthy type of cholesterol, thus improving the HDL to
total cholesterol ratio.
Also, many diet plans that do not strictly limit the total amount of dietary fat a person consumes have been associated with
better diet satisfaction, weight loss, and preservation of muscle mass.
Comment: What's not stated in the article is that these kinds of false hopes are sold to the public as part of an ongoing narrative meant to convince us of the awesome power of human science to overcome all our problems. The cure for [insert chronic disease here] is perpetually "just around the corner". The fact is, the human race, but particularly pharmaceutical companies, actually know very little about these chronic diseases, but few are willing to admit this.
