Avocados may be high in fat, but it’s a good fat, the heart-healthy monounsaturated kind.  They also contain beta-siterol, which is a plant sterol that may actually help lower cholesterol.  Avocados are one of the world’s most perfect foods because they are rich in nutrients like vitamin C, potassium, folic acid, lutein (good for eye health), and fiber.  It’s easy to incorporate avocados into your diet: Instead of mayo, spread a little avocado on your sandwich!  Add a few chunks of avocado to your salad.  Use avocado slices as a garnish on soup.  Make a yummy guacamole with mashed avocado, a little green onion and garlic and some diced tomatoes – add cilantro to taste.  Or make a veggie pizza with fresh avocado on top!  There are many varieties of avocado, but generally, an avocado is ripe when it yields to gentle but firm pressure.  Don’t refrigerate avocados until they are completely ripe.  If you’re eating half an avocado and saving the rest for later, keep the seed with the saved half, and spread a little lemon juice over the exposed part before wrapping to prevent the iron content from turning the avocado brown.
