Avocados are a great source of vitamins C, E, K, and B-6, as well as riboflavin, niacin, folate, pantothenic acid, magnesium, and potassium. They also provide lutein, beta-carotene, and omega-3 fatty acids. Eating an avocado a day is good for your health. Avocados are a fun food to eat, they’re nutritious, and they’re a good source of monounsaturated fat, which can reduce your risk of heart disease. Ripe avocados should yield to gentle pressure when squeezed.
