healthy fat: avocados

Long before we knew of "healthy fats," all fats were condemned. In a paper published in the Journal of the History of Medicine and Allied Sciences in 2008, researcher Ann F. La Berge traced the convoluted history of dietary fat and how the United States became swept up in an "ideology of low fat" beginning in the 1960s. For decades, Americans shunned fat, "even though there was no clear evidence that [a low-fat diet] prevented heart disease or promoted weight loss."

Beginning in the early aughts, views on fat began to change, and most health professionals now believe fat is a critical part of the diet. Along with carbohydrates and protein, fat is one of three macronutrients that your body needs to survive and thrive. But just how much fat should you be eating each day? According to the 2015–2020 Dietary Guidelines for Americans, between 20 percent and 35 percent of our daily calories should come from fat. For someone eating 2,000 calories a day, that translates to 44 to 77 grams of fat.

However, not all fats are created equal when it comes to their healthiness. So which fats are good for you and what exactly do they do for the body? This is everything you need to know.
