Avocado has a bad reputation since it's high in calories, but this creamy fruit is also high in oleic acid, a healthy fat that may help lower cholesterol. Avocados are also high in potassium, vitamin K, and fiber. Just like nuts, don't overdo and just slice up a quarter of one in your salad. It adds 80 calories, 244 mg of potassium, 3.4 grams of fiber, and one gram of protein.
