Eggs are controversial. Some people say eggs are superfood as they are rich sources of protein and vitamins, while others say they contribute to diseases as egg yolks are high in cholesterol.

According to a study in 2018, healthy people could eat one egg a day. According to a study in 2019 published in JAMA (the Journal of the American Medical Association), however, one egg a day could raise the risk for cardiovascular disease and early death.
So how should people eat eggs?
1. Eating fewer than three eggs a week
The study published in JAMA found no increased risk from eating eggs if people took fewer than three eggs a week.

2. Using Parmesan instead of other cheeses
Many people tend to add a lot of cheeses when making egg dishes. Egg yolk itself has only 70 calories, but cheeses you add may bring you hundreds of calories and saturated fat.
Next time try to use Parmesan instead of other cheeses. Parmesan is lactose-free and low in fat. Besides, Parmesan tastes better than many other cheeses.

3. Adding fresh vegetables
Vegetables can add more nutrients to your recipes. Let me tell you, there is nothing better than a plate of steaming veggie-filled eggs. And it is very easy to make.
