Nutritionists used to warn against eating eggs for health reasons. Today, the opposite is true. Eggs are a good source of protein, with less than 100 calories. A large hard-boiled egg contains about 71 calories, with more than 6 grams of protein and 5 grams of fat.
Here’s how the different parts compare:
Boiled egg whites:
Hard-boiled Egg Yolk:
“Eggs are considered the purest source of protein and the best bang for your buck,” says Emily Tilles, MS, RDN, CDN, a registered dietitian nutritionist in Rochester, New York. “They have a broad mix of fat-soluble and water-soluble vitamins.”
Eggs contain several essential vitamins as well as some minerals including calcium and iron. They are one of the few food sources of vitamin D, one of those fat-soluble vitamins. Fat is needed to absorb vitamin D, which egg yolks provide. Egg protein also contains all the essential amino acids.
Caution? Cholesterol in yolks. Although experts now believe that dietary cholesterol has little effect on blood cholesterol, one hard-boiled egg contains 186 milligrams, or 71 percent of what the FDA recommends per day.
Science shows that otherwise healthy people can enjoy a few eggs per day while the American Heart Association recommends one egg (or two egg whites) per day.
