Is Saturated Fat Good, Bad, or Neutral?

by Jackie Wicks

Maybe It’s Not Saturated Fat, but Saturated Fat Still Doesn’t Help

If you have heart disease or are at risk of it, then optimizing your diet to lower that risk is important, and regardless of the role saturated fat ultimately plays we know already that it’s at most neutral. Optimizing your diet doesn’t just mean getting rid of the bad foods, it also means moderating the foods that don’t have any substantial benefit. Fruits, veggies, legumes, and whole grains all have substantial benefits (fruits and veggies especially), but most types of meat really don’t. Sure, we can maintain the same intake of high-saturated fat foods (like meat) and potentially no suffer any further downsides, but we also miss out on the upsides of a healthier diet.

[quote align=”center” color=”#999999″]Some of the diets recommended by those who don’t believe in the saturated fat/heart disease link have been shown to increase risk. Even if saturated fat isn’t a problem, their recommendations can still be harmful.[/quote]

The health professionals telling heart disease patients that saturated fat isn’t a risk are missing the point. It’s not just about saturated fat, it’s about diet in general. Unless you eat too little, you can’t add foods without either taking other foods out or eating more than you already were. The diets they recommend, typically low-carb and high-protein/fat, are relatively unstudied for heart disease risk and the studies which have been done don’t paint a pretty picture (at least not when they’re based on animal protein, the only type of high-protein food which is also high in saturated fat).12,13

Don’t gamble with your health. The recommended diet for heart disease isn’t sexy, and it’s not the type of diet that attracts devotees. What it is is a diet that will decrease your risk of developing or dying or heart disease. Considering that it’s a diet designed solely for the prevention and treatment of heart disease, I’d say it does its job well!
