Why is consuming fats so important from birth?

Currently due to different investigations and access to them through the Internet has led the population to adopt various diets with an emphasis on different foods that provide different nutrients and consequences. Since we are born, fat consumption is essential, but over the years we have erroneously distanced ourselves from its important function.

A study by the International Journal of Research on Vitamins and Nutrition explains that the composition of human milk is the result of the evolution of mammals over millions of years. Among the most important components of milk are fatty acids.

"Approximately 85% are saturated and monounsaturated fatty acids; the rest are polyunsaturated. Their function is to provide energy and immunity and serve as building blocks, as well as aiding the hormonal system".

The structural differences between fatty acids determine their biodiversity and give them a particular physiological importance. The proper development of the nervous system, the retina, and other structures depend on an adequate supply of these fatty acids during intrauterine development and in the newborn and infant stages. The fats present in milk form milk fat globules, structures that do not appear in the milk formula prepared with vegetable oils.

Milk's unique composition and extraordinary complex structure, made up of macromolecules and particles, is the result of 150 million years of mammalian evolution. Over time, this has produced a healthy food that provides nutrition and immune protection.

One of the most important substances in milk is fatty acids, which ensure the correct development of the child in the prenatal, postnatal and infant stages. Proper supply of these at intrauterine, postnatal, and infant stages of development ensures adequate development of the nervous system, retina, and other structures. The fat in human milk provides almost 50% of the energy intake for young babies".

If we are adapted millions of years ago to process fat as energy and nutrient, it is natural to conclude that our adult diet should consist mainly of meat and fish. However, since the 1960 Ancel Keys study that indicated that fats produced heart attacks, many countries have drastically reduced their intake by replacing it with carbohydrates (bread, rice, pasta, etc.). But the Keys study had a bias, only published 7 of the 22 countries that confirmed the theory that fat produced high rates of heart attacks, leaving out the other countries that also had high fat consumption and low attack rate. cardiac, according to the later investigation of Jacob Yerushalmy that looked for to confirm the one of Keys.

Currently developed countries have spread the study that the consumption of sugar and carbohydrates should be reduced to a minimum since once consumed they are converted to glucose. The free fatty acids that we have been used to consuming since we were born millions of years ago need a molecule of gricerol (sugar or carbohydrates) to transform into body fat. Animal fat is not the same as body fat.

If we don't overeat carbohydrates, acids cannot be converted to triglycerides - that is, they cannot be converted to body fat, say doctors and scientists promoting low-carbohydrate diets around the world.

Undoubtedly fatty acids have been essential in human life and its genetic load. The result of millions of years of evolution in mammals, during which milk composed primarily of fatty acids, became the only natural source of nutrition for offspring in the first weeks of a child's life. And, for millions of years man used the energy of animal fat to reach the contemporary days, influencing even the development and size of the brain of the modern human.
