Most people believe that the nutritional content of eggs is mainly in the yolk. When coaxing children to eat, most adults will say: Even if you don’t eat egg whites, you should eat egg yolks. Egg yolks have higher nutritional value; while middle-aged and elderly people hear about egg yolk cholesterol High content, generally do not eat egg yolk, only eat egg whites, or dare not eat eggs.
Let’s talk to you today, what is the difference between the nutritional value of egg yolk and protein? Can the elderly eat egg yolks?
eggs have a ratio of amino acids very close to the human body's needs, so the protein in eggs is very easy to be absorbed, and it is also one of the most important nutrients in eggs.
From the perspective of protein, the proportion of protein in the yolk is indeed higher. The protein contains about 11% protein, and the egg yolk contains about 17.5% protein.
However, this does not mean that egg yolk is more nutritious than egg white, because the quality of egg yolk and egg white are not the same. An egg has less egg yolk but more egg white. The overall weight of egg white is a little more than twice that of egg yolk. There is more protein in the yolk than in the egg yolk.
Therefore, in terms of protein content, the protein content of egg white and egg yolk is roughly the same, and both egg white and egg yolk contain eight kinds of essential amino acids, both of which are high-quality protein. Just eating the egg yolk will lose the protein content. nutrition.
In addition to protein, there are other nutrients in eggs, such as fat and cholesterol. An egg contains about 5g of fat, and basically 98% of the fat may be on the yolk, while the cholesterol in an egg is about 200 mg, all on the yolk.
Hearing this, everyone may think that it is better to eat protein. In fact, fat and cholesterol are also nutrients that our body needs. For normal people, the cholesterol that is eaten has no effect on the cholesterol content in the body, even for patients with three highs. In other words, eating one egg a day is not a problem at all.
and the egg yolk also contains phosphorus, calcium, iron and other minerals, fat-soluble vitamins, such as vitamins A, D, E, K and most of the B vitamins, as well as some lutein and zeaxanthin which are beneficial to eyesight. Lecithin and betaine for the prevention of chronic diseases. Wouldn't it be a waste of these nutrients if you only eat protein?
In short, the nutrient content in egg yolk and albumen is very rich, the most important nutrient ingredient-protein content is similar, and cholesterol and fat are concentrated in the egg yolk, but it is not harmful to the human body, middle-aged and elderly people can also eat , Eating eggs or eating all can get more comprehensive nutrients.
