Eggs are rich in protein, nutritional powerhouses and considered superfood. While relatively high in cholesterol (about 212 mg in a hard-boiled egg), in moderation, they won't do any harm. In fact, research has shown that eating up to seven eggs in a week doesn't increase your risk for heart disease.

A hard-boiled egg is a convenient and energy-boosting snack. But how many calories are in a hard-boiled egg?

A hard-boiled egg has around 70 calories. Cut on top of a salad or just enjoyed on its own, a hard-boiled egg is a healthful addition to any diet. With 6 grams of highly-digestible protein and a healthy dose of vitamins and minerals, eggs add good nutrition to your day. What's more, more than half of the 5 grams of fat in an egg are unsaturated.

Make some hard-boiled eggs and store them in your fridge (shells on) for convenient and nutritious snacks.
