It is generally known that among doctors and nutritionists is no consensus when it comes to the representation of certain foods in the human diet, as is the case with pork fat. In fact, for several decades, it is believed that it is very unhealthy because it is rich in saturated fat, which supposedly clog blood vessels and cause auto various diseases. Some doctors and medical organizations such as the American Heart Association and the Center for Disease Control and Prevention, today recommended the maximum reduction in fat intake of animal origin, while, on the other hand, the results of the latest research seriously call into question the legitimacy of the decades-long demonization of these foods.
(Un)justified the bad reputation
Saturated fatty acids, for which he pilloried, make up only about 40% of the total amount of fat in the composition of pork fat. Since the rest belongs to the so-called. Healthy, unsaturated fats, this food is actually richer than their olive oil – which contains 45% monounsaturated fatty acids – or fats and other plant and animal origin. Lard is also resistant to high temperatures than vegetable oils, which in the long-term cooking changes the chemical structure, which can be very harmful effect on health. In addition, it is, as opposed to vegetable oils, without fear can be used repeatedly. This food is also one of the best natural sources of vitamin D, a nutrient suffers from whose lack of even 50% of the world population, but it goes without saying that the lard in its natural form does not contain the notorious trans fats, which are rich in industrially processed vegetable oils and margarine. Does all this in mind, it is clear why her numerous health experts, and gastronomes, give priority over all other types of fat.
It has long been believed that saturated fatty acids in foods of animal origin increase the risk of cardiovascular disease, although they are still almost two decades ago, scientists discovered that this is not so. The results of a six-year research published nearly 20 years ago in one American study – indicate a weak association of saturated fat with increased risk of heart disease, as well as the much larger influence of other factors, such as total calorie intake and dietary fiber. Scientists from the University of Georgetown also consider the health of the most important lifestyle and a balanced diet – one that includes all foods in the right proportion, considering their nutritional and energy value. One of them – the professor Tomas Serman – points out that lard itself is neither healthy nor unhealthy, if in limited quantities represented in diverse diet, a poor carbohydrate and white sugar. On the other hand, recent studies say that saturated fatty acids, in no way affect the development of cardiovascular diseases – they raise the levels of good cholesterol in the blood if they are an integral part of the diet with reduced intake of carbohydrates.
Better and worse variants
There are better and worse variants of lard, they also need to pay attention. In fact, studies have shown that fat originating from animals that are bred and feed on pastures, richer in unsaturated fat and healthier than animal fats commonly fed corn and concentrate. In addition, the fat which is sometimes sold in stores as a natural lard can be subjected hydrogenation, chemical – technological process in which trans fats are formed, it is definitely advisable to carefully read the declaration.
