Eggs: What You Should Know About Nutrition, Cholesterol and Safe Consumption
Adrian Mercer
Small in size, eggs contain many nutrients the body needs. They provide high-quality protein, energy, fat, vitamins and minerals. Because they are easy to buy, cook and eat, eggs are part of many families’ diets. But it is not accurate to treat eggs as a cure-all or as a food everyone must eat every day. Their benefits depend on a person’s health, overall diet and how the eggs are prepared.
A medium-sized egg weighing about 50 grams provides roughly 6 grams of protein, 70 calories and 5 grams of fat. Its protein contains all nine essential amino acids the body needs, which is why eggs are considered a source of complete protein. The white contains mainly protein, while the yolk provides protein along with fat, vitamins and other micronutrients.
The yolk contains nutrients such as choline, selenium, phosphorus, vitamin B12 and riboflavin. Choline is needed for cell structure, the nervous system and various biological processes in the body. Eggs also contain pigments such as lutein and zeaxanthin, which play a role in normal eye function. However, it would be misleading to claim that eating eggs cures disease or certainly prevents vision loss.
Eggs in children’s diets
Children need sufficient energy, protein and various micronutrients for growth and development. Eggs can provide some of these nutrients and be a useful food. But eggs alone cannot solve malnutrition. A varied diet that includes grains, lentils, vegetables, fruit and other sources of protein is needed, according to children’s ages and nutritional needs.
When deciding whether to include eggs in school meals, nutrition should be considered alongside cost, availability, storage and safe preparation. Eggs can be a convenient source of protein, but they should not replace other nutritious foods. Families and schools can prepare varied meals by combining eggs with locally available foods.
The misconception that the yolk should be discarded
Some people believe the yolk should be discarded and only the white eaten because the yolk contains cholesterol. But doing so can also mean missing choline, vitamins and minerals found in the yolk. One large egg may contain about 185 to 200 milligrams of dietary cholesterol. The amount can vary with diet and egg size.
Dietary cholesterol and cholesterol measured in the blood are not the same thing. The body also produces the cholesterol it needs, and the effect of dietary cholesterol on blood levels varies from person to person. Recent heart-health guidance places emphasis on the overall diet rather than blaming a single food. Eggs are often eaten with ghee, butter, a lot of oil, processed meat or salty foods. In such cases, the other foods and the method of preparation also affect the quality of the diet.
According to American Heart Association guidance, most healthy people can include up to one whole egg a day as part of a heart-healthy, balanced diet. This is not a required amount for everyone or an individualized medical recommendation. People with high cholesterol, diabetes, heart disease or other chronic conditions should consult a doctor or nutritionist based on their health, medications and overall diet.
Safe cooking and storage
Although eggs are nutritious, raw or undercooked eggs can carry a risk of foodborne infections from bacteria such as Salmonella. It is safer to cook eggs until both the white and yolk are firm. Hands, utensils and work surfaces should be cleaned after handling raw eggs. Eggs should be stored at a safe temperature, and cracked or visibly contaminated eggs should not be used. For dishes that call for raw or undercooked eggs, pasteurized eggs are a safer choice.
Egg prices and availability vary by location, so they cannot always be described as an affordable option for everyone. In many cases, however, eggs are easy to prepare and can be used in a variety of dishes. They can be boiled, poached or cooked with a small amount of oil. Pairing them with vegetables and grains, instead of regularly cooking them with excessive salt, ghee or processed meat, can be a more balanced choice.
Eggs should not be completely avoided out of unnecessary fear, nor should their nutritional value be exaggerated as a solution to every health problem. Portion size, preparation and their place in the overall diet all matter. Including eggs in a varied, balanced diet in a way that suits one’s health is a practical approach.
