The egg is a food rich in proteins of high biological value and very complete nutritionally. Let’s know all the health benefits

The egg provides us with proteins of high biological value . In fact, the balance between the amino acids it provides is perfect and it is used as a reference standard against the rest of protein products. Its caloric content is not high and the ratio between the content of monounsaturated, polyunsaturated and saturated fatty acids is more than acceptable. It also provides us with vitamins such as A, D, E, B2 and B12 … and minerals such as phosphorus, selenium, iodine, iron and zinc … The egg white is an aqueous solution with a considerable protein content while the yolk is an emulsion of fat in water where almost all the fats and cholesterol it contains are found.

Questions and answers about the egg

  • Are brown eggs better than white ones?

The color of the egg shell is due to the type of hen and there are no nutritional differences between the two.

  • Are more intensely colored yolks more nutritious?

The intensity of color of the egg yolks varies depending on the hen’s diet, but we should not take it as a sign of greater nutritional capacity.

  • Should eggs be washed before eating?

The answer is no, not only do we not manage to eliminate the risk of foodborne infections by washing them, but we also increase it since the shell is porous and we favor the entry of microorganisms.

  • How many eggs can be eaten a week?

In general, the recommendation for the consumption of eggs is 3 to 4 a week. In physically very active people or in periods of growth, 7 eggs a week could be consumed. What is not advised is the consumption of more than one yolk a day.

How to take them

The egg is a fantastic ingredient that confers texture, cohesion, acts as an emulsifier, has the ability to coagulate, to form foams, etc. It is found in many pastry recipes and is a fundamental ingredient in many sauces such as mayonnaise, hollandaise sauce, tartar, aioli, etc. In addition, it can be consumed cooked, soaked, scrambled, blanched, fried or fried … and, of course, in an omelette.

How to know if an egg is fresh?

There are tricks to detect the degree of freshness of the eggs. If we submerge it in water and it floats, it means that the air chamber inside it has grown substantially, so the egg is not fresh. Once opened, if the white spreads on the plate and the yolk is displaced, it is also a not very fresh product, on the other hand, if the white is compact and puffy and the yolk is more or less centered on it, we are facing an egg cool.

Who are they suitable for and who are not?

The egg weighs is a food that can be part of a balanced diet . It is advised in:

  • Growth stage . The protein content of high biological value and its large amount of vitamins and minerals make it a very interesting food for stages of development with high nutritional needs.
  • Pregnant and lactating . Due to its nutritional content and especially for its contribution of choline, which intervenes in the formation of structures of the nervous system, it is an interesting food for these stages.
  • Elderly . It is a food that is easy to chew and digest, although the latter depends on the type of cooking. It is a complete and suitable food for older people who, with a light intake, should take well-nutritious foods. Its cholesterol content should not be a reason for limitation in elderly people, since in this case moderate hypercholesterolemia does not seem to have sufficient clinical relevance.

It is not convenient in:

  • Egg allergy . It is one of the foods that causes allergies more or less frequently. If there is a diagnosis of egg allergy, its presence should be eliminated in the diet, both in eggs and in products that contain it.

Buying and conservation advice

Commercially available eggs are at room temperature as they are well preserved if the temperature and humidity are not too high, and thus temperature fluctuations are avoided. If we can, at home it is preferable to keep them in the refrigerator to extend their useful life. When we buy eggs we must make sure that we do not acquire broken specimens or with cracks in the shell . In addition, we will check that they are within the preferential consumption period and we will check their size and the way the laying hens are raised. Regarding the size we can find small eggs of less than 53 g; medium, 53 to 63 g; large, 63 to 73 g; and super large, 73 g or more.

Preparations made with eggs must be consumed at the moment and if not, they must be refrigerated and consumed within a maximum of 24 hours. In summer we must take extreme precautions. In any case, it is advisable to cook egg products so that they reach 70 ºC to increase the guarantees of safety.
