Avocados have earned their reputation as a “superfood” — packed with heart-healthy fats, fiber, potassium, and antioxidants that boost brain function and promote radiant skin.

But even nutrient-rich foods can lose their benefits if consumed the wrong way. The way you prepare and eat avocados can make all the difference between helping your health and unintentionally harming it. Here are three common mistakes to watch out for.

1. Eating Too Much at Once

Though avocados contain good fats, overindulging can backfire. A single medium avocado provides about 240 calories and 22 grams of fat. Eating one or two per day can quickly push your calorie intake over the limit, especially for those trying to manage weight.

Nutrition experts recommend sticking to half an avocado per serving to keep things balanced. Overeating can also cause bloating or mild digestive issues because of the fruit’s high fiber content.

2. Pairing Avocado With the Wrong Foods

Many people enjoy avocado with white bread, bacon, or heavy mayo, assuming they’re making a nutritious meal. In reality, combining avocado with refined carbs or processed fats negates many of its heart-healthy benefits.
