Avocados are a favorite of the produce section. they're turning up in everything from salads and wraps to smoothies and even brownies. 

Avocados have a lot of calories. The recommended serving size is smaller than you'd expect: 1/3 of a medium avocado (50 grams or 1.7 ounces). One ounce has 50 calories.Avocados are high in fat. But it's monounsaturated fat, which is "good" fat that helps lower bad cholesterol as long as you eat them in moderation.
Avocados are low in sugar. And they contain fiber, which helps you feel full longer. In one study, people who added a fresh avocado half to their lunch were less interested in eating during the next 3 hours than those who didn't have the fruit.
