The Classic Breakfast Food You May be Overlooking

We're talking about: Eggs
Why you should eat more of them: The "bioavailability of the nutrients" in your food probably isn't something you think about much (or at all, or even know what it means). The easy explanation: It refers to the proportion of a given nutrient that your body actually absorbs from a food and puts to use. Eggs score a perfect 100 on the bioavailability index for protein, higher than any other food.
Keep this in mind too: The yolk contains healthy fats, antioxidants and vitamins, including choline, which helps your brain and nervous system function properly, says Sowa. Women, especially those who are pregnant, may be too low on the essential nutrient, according to a review from the University of North Carolina at Chapel Hill. Worried about cholesterol? Don't be. One 2015 American Heart Journal study found that eating 3 eggs a day didn't raise cholesterol levels—even in people with coronary artery disease.
