Why you should not be afraid of animal fats, or How nutritionists justified them

Animal fat is usually blamed for many troubles, whether it’s overweight or health problems. In our minds, the conviction of its harm is firmly seated. Moreover, for the last 50 years it was believed that such fats harm the heart and blood vessels. As it turned out, all this is a big misconception.

Background of the issue

In 1961, Dr. Ansel Keys published his research, according to which in countries where the consumption of animal fats is high, people are more likely to face the problem of heart attacks and strokes. The study became a real sensation, the idea of “harmful fats” and dangerous cholesterol was immediately picked up by the media. On this basis, a whole industry of fat free or “cholesterol-free” products has grown. For decades, animal fat was cursed, and “fatty” was encouraged only in the form of vegetable oils. People refused butter in favor of “healthy”, in their opinion, margarine. Omelets for breakfast also fell out of favor, which were replaced by sweet flakes with juice. Although, as it turned out later, it was not only useless, but even harmful. If the composition of the oil is always clear – cow cream, then in margarine they are replaced by several lines of questionable and harmful components. Ready-made flakes also did not pass the benefit test, as they contain simple carbohydrates that quickly increase blood sugar levels.

Dr. Atkins was the first to challenge Kees’ theory of “harmful fats”. In 1972, his book “Revolutions in the Diet” was published, which states that limiting carbohydrates plays a crucial role in weight control, and fats can not be limited. Despite the success of the weight loss technique, Atkins and his protein diet were rightly criticized by doctors and then no one seriously listened to him.

In the 1980s, the trend continued. And only in the 1990s, but most actively in the 2000s, serious clinical studies began to be conducted, which confirmed that the theory of “dangerous fat” — . In the end, scientists and doctors came to the conclusion that Kees simply falsified the facts. Because there are many countries – Holland, Sweden, Norway – where high consumption of animal fat does not correlate in any way with overweight and heart diseases of citizens.

A real revolution in the minds of millions of people was the cover of Time magazine (2014) with the words “Eat butter. Scientists have declared fat the enemy. Why they made a mistake.” In the text of the article, it was told for several turns that the real enemies of our health are simple carbohydrates (including sugar). They cause spikes in blood sugar, due to which a momentary feeling of satiety is replaced by a sharp feeling of hunger, and we begin to overeat, accumulating excess weight as a result.

The benefits of fats

Fats are of vegetable and animal origin. The latter can be found in butter and various dairy products, meat and animal fat. Despite the great nutritional and energy value of fats, they should enter our body in a very large amount, amounting to 30% of the total calories consumed.

“If we talk about milk fat, which, according to statistics, is most often preferred to be excluded from the diet, choosing dairy products with a low fat content or fat free at all, then you should not be afraid of it at all. It is easily and almost completely absorbed by the body. This happens, firstly, due to the fact that it melts at a temperature of 25-30 degrees Celsius (below human body temperature), so that it enters the intestine in a liquid state. Secondly, this fat is found in milk in the form of tiny particles of several microns in size, each particle is completely enveloped by food juices in the stomach, and this also facilitates assimilation.  Milk fat contains more than 140 types of known acids, in addition, it is rich in phosphatide – lecithin, which prevents vascular sclerosis, promotes proper fat metabolism and prevents them from being deposited in the liver.

And finally, fats of any kind in a certain amount are necessary for the body for the well-coordinated work of organs. For example, the gallbladder produces bile specifically to digest fat. If he has nothing to process, the bile stagnates, stones appear,” says Svetlana Vitkovskaya, a representative of the Cheburashkin Brothers company. Family farm”.

Animal fat gives a feeling of satiety for many hours, it makes the taste of food complete, sending positive reinforcement to the brain “nutritious food has been received, you can not eat anymore.” It has a positive effect on the gray matter of the brain, and contains carotene and lecithin, vitamins A, E, D, necessary for the normal functioning of the body.
