Opinions on eggs are increasingly mixed: some consider them the most nutritious food in the world, others fear them because of their high cholesterol content. Both opinions are correct, but the universal importance of this food in the human diet cannot be denied. What problems arise if you eliminate eggs from the diet? Chicken eggs, that is to say the most commonly consumed, are in fact highly nutritious: they provide complete proteins in large quantities, and above all of high quality, and therefore provide all the essential amino acids that the organism is not able to produce by itself. .
They also provide significant amounts of vitamins and minerals, including vitamin A, BV, B12, riboflavin, folic acid, choline, iron, calcium, phosphorus, and potassium. Eggs are therefore a good source with a very high protein and nutritional value, but at a very low cost. We must not forget either the lipid component and it is represented only at 65% by triglycerides (compared to 98% of other foods), and by the abundant presence of lecithins (contained in the yolk) and in general of phospholipids (30%) that they confer healthy and functional properties, including the emulsifying power which allows the preparation of certain foods, such as mayonnaise, or even more the presence of fats which, although of animal origin, are mainly monounsaturated and polyunsaturated.
On the other hand, however, there is a large amount of cholesterol (5%, about 200 mg/egg), so consuming even two eggs far exceeds our estimated daily requirement of 300 milligrams. However, it must be said that the presence of lecithins promotes, on the one hand, the reverse transport of cholesterol from the arteries to the liver and, on the other hand, it improves brain performance and the different digestive processes of food. Two boiled eggs, for example, are eliminated from the stomach in about two hours, compared to the three needed for one serving of meat.
Digestion times are proportional to the amount of fat used and increase considerably if the condiments are brought to high temperature, as happens for example in the case of fried eggs. Therefore, sabayon and omelettes are absolutely not recommended for people with liver stones, since the large amount of lipids stimulates the contraction of the gallbladder, sometimes causing painful colic. But there is also other great news: recent studies have confirmed that moderate egg consumption is not at all associated with an increased risk of cardiovascular disease, except for diabetics. This does not mean that in the presence of this disease, eggs should be completely excluded from the diet, but only eaten more moderately and without overdoing it.
