Other sources of unsaturated fats include olive oil, nuts and oily fish. A meta-analysis in 2015 examined 10 studies on avocado and cholesterol. It found that when participants replaced animal fats with avocado, their LDL cholesterol and triglyceride levels decreased. High triglycerides, along with high LDL or low LDL levels, can increase the risk of heart attack or strokes. However, avocados didn’t significantly affect LDL cholesterol levels. While some argue that avocados don’t lower cholesterol directly, but rather through replacing animal fats, avocados contain phytosterol, which can lower LDL cholesterol. However, the amount in one avocado is insufficient compared to the recommended intake for cholesterol reduction. Yet, avocados can still benefit cholesterol. A 2018 study noted that while they didn’t lower LDL cholesterol or fat levels, they did raise HDL cholesterol levels. Thus, including avocados in a balanced diet with less animal fat may positively impact HDL cholesterol levels. In essence, no single food determines a diet’s healthiness.
