Avocados are filling, nutritious, and delicious. They have monounsaturated fat (the good kind) that actually helps lower cholesterol. And they also contain beta-sitosterol, a natural substance shown to significantly lower blood cholesterol levels. I like to slice avocado and eat with eggs, mash them into a scrumptious guacamole, chop some into my salad, whir some into my smoothies, or simply slice them and place on a plate with a squeeze of lemon juice and a sprinkle of sea salt.
