Technically a fruit, avocados are in their own unique category when it comes to their nutritional properties. These fruits are a great source of dietary fiber, folate, vitamin B6, potassium, iron, niacin, vitamin E, and monounsaturated fats. Yet, it is true that they are high in fat – one medium avocado contains 30 grams of fat. Fortunately, it’s healthy fat rich in omega-9 fatty acids, or monounsaturated fats, which appear to have neutral if not protective effects against cancer. Nonetheless, given that you’re likely consuming other fats in the diet, consider keeping your portion to 1/4-1/2 avocado at a sitting.
