Avocados are a staple food for increasing testosterone. Yet, they are hated by people who still cling to the ineffective and testosterone lowering low-fat diets. This is because 77% of the calories in an Avocado comes from fat. What is even better is that Avocados are rich in the testosterone-boosting types of fat-saturated fats (SFAs) and monounsaturated fats (MUFAs), while they are low in the testosterone-lowering polyunsaturated (PUFAs) fat. The fatty-acid ratio in Avocados is 16% SFA, 71% MUFA and 13% PUFA.
