A recent study has revealed data that flies in the face of decades of conventional wisdom. For years full fat dairy has been under attack because of the belief that saturated fats lead to increases in heart disease and strokes.
The first solution that was offered was to switch from butter to margarine and corn oils. People were later told that they should not use margarine because of the dangers of trans-fats. The solution was to switch to low fat products.
Nutritionists and dietitians embraced this advice, and have been passing that advice along to anyone who will listen. Government agencies like FDA and USDA have also touted the benefits of low fat dairy.
The industry boomed as consumers flocked to low fat and skim milk, low fat and fat-free cheese, sour cream, yogurt, and much more.
However, a meta-analysis released by the American Journal of Clinical Nutrition concluded that consuming saturated fat "was not associated with an increased risk of coronary heart disease, stroke, or cardiovascular disease."
This meta-analysis looked at the results of 21 separate studies, examining 347,747 men and women of various ages and concluded that age or gender did not matter. The results were the same for both men and women, regardless of their ages.
Once again "conventional wisdom" has proven to be based on faulty research. Incomplete data was used to influence the mindset of a generation of nutrition experts. As more complete research is completed, those decades old conventions are falling.
