For years, the egg has been considered a food of dubious quality for health. However, the latest studies show the exact opposite. In fact, egg consumption has been shown to have no effect on blood cholesterol. One wonders if even egg proteins are unable to decrease blood pressure.
Years ago, it was thought that the amount of eggs that could be eaten per week was limited. Today, experts do not limit their consumption. It is clear that it is advisable not to overdo it and to follow a varied diet rich in fruits, vegetables and fresh foods. But the recognized benefits of eggs are many.
Egg proteins and blood pressure
The presence of a peptide in egg white proteins that has an impact on blood pressure was investigated . Apparently, it would be a peptide that inhibits the angiotensin converting enzyme and thus blocks the increase in blood pressure.
However, heat-treated egg proteins are thought to produce a greater antihypertensive effect. Therefore, the consumption of eggs could be considered a complementary treatment to the use of drugs to reduce the level of blood pressure. This is because egg is a natural source of protein.
However, further studies are needed to verify the efficacy of this peptide and subject it to different conditions. At the moment, however, it can be said that regular egg consumption can be similar to administering a low dose of captopril, but without developing side effects.
All the articles published talk about experimentation on animals; therefore, human studies are also needed to extrapolate these data.
The egg: a complete food
Aside from studies on the relationship between egg protein and blood pressure, egg possesses many nutrients that are beneficial to health. First, it is a food rich in vitamin D, a nutrient that tends to be deficient in many people.
This vitamin is closely related to bone health, the immune system and the prevention of complex diseases. Furthermore, it is a micro nutrient that the body can synthesize thanks to exposure to the sun, but in the absence of it it must be included in the diet.
In addition, it contains a good amount of fatty acids. The vast majority are of the saturated type, but despite popular belief, these fats are necessary for the proper functioning of the body.
Easy to prepare
Another advantage of the egg is that it can be prepared in many different ways. Whether in a pan, as an omelette or scrambled, eggs are always good. The preparation methods are generally simple and quick and goes well with various types of foods.
It is only necessary to moderate the consumption of fried eggs, due to the fact that the frying can contain unhealthy products, such as acrylamide for example.
It does not raise cholesterol
Diet has very little influence on blood cholesterol levels. Few foods can raise this level and they do so in very small ranges of values.
Likewise, there are a few ways to lower cholesterol through diet, in addition to the regular consumption of fish and nuts. As a warning, beware of fatty acids, which appear to be the most dangerous for cardiovascular health.
Some studies on egg consumption and lipid profile ensure that consuming 4 eggs per week increases cholesterol in the same way as consuming 16 eggs.
Therefore, there is a small initial increase, nothing to worry about, which is maintained as the intake of this food increases. Furthermore, nowadays there are also doubts about the influence of cholesterol on the risk of cardiovascular disease, so these are parameters that are by no means definitive.
Conclusions on egg proteins
Egg is a very interesting food that must be present in the diet on a regular basis. It is an excellent source of muscle protein and a source of vitamin D. Furthermore, there are indications that it could have an interesting antihypertensive effect in humans, along with the use of drugs.
Finally, it is worth refuting the fact that the egg affects cholesterol levels and that the number of these weeklies must be limited. However, the most appropriate thing is to seek advice from a nutritionist to establish an appropriate meal plan for your specific needs.
