Avocados are known for their abundance of healthy nutrients and numerous health benefits. But what are these nutrients and benefits exactly? Avocados are full of heart-healthy monounsaturated fats that can help lower your cholesterol levels. Dr. Frank Hu and his team at Harvard studied the effects of avocados on the health of 110,000 adults over 30 years old. The research team found that people who ate at least 2 servings a week had a 21% lower risk of coronary heart disease. Avocados are great for your gut microbiome as they are high in fiber, which helps with weight control and healthy gut activity. It contains vitamin £, which can help keep the skin healthy, lutein, which aids vision, and potassium, which helps reduce high blood pressure. However, Dr. Martin Kohlmeier, a professor at the University of North Carolina, says, "Many reported effects are replacement effects."
