Change the fat for vegetable oil
Found a way to avoid premature death
Researchers from Harvard University have found that the consumption of large amounts of unsaturated fats, which are contained in vegetable oils, is associated with a low probability of early death. At the same time, a diet containing a large amount of animal fats, on the contrary, contributes to the deterioration of health. Article by Wang et al. Association of Specific Dietary Fats With Total and Cause-Specific Mortality is published in JAMA Internal Medicine.
According to scientists, their work is currently the most complete and thorough verification of how fats in food affect the state of the body. Nutritionists have found out that if you replace the saturated fats contained in butter, lard and red meat with unsaturated olive, rapeseed and soy oils, you can avoid serious health problems.
Nutritionists studied the data of 126 thousand people who took part in two long-term studies: Nurses' Health Study and Health Professionals Follow-Up Study. Volunteers for 32 years periodically, every two to four years, filled out questionnaires, answering questions about diet, diet, lifestyle and health. For the entire time of the study, 33 thousand people died. Scientists have tested whether there is a link between nutrition and deaths resulting from cardiovascular diseases, cancer, neurodegenerative disorders and lesions of the respiratory system.
It turned out that different types of fats had different effects on the state of the body. Trans fats (found in meat and dairy products) were the most harmful: if you increase their consumption by two percent, the risk of premature death will increase by 16 percent. A five percent increase in saturated fat intake is associated with an additional eight percent of deaths. But unsaturated fats have the opposite effect. The diet enriched with them reduced the probability of death by 11-19 percent. Replacing saturated fats with carbohydrates only marginally improves health.
Unsaturated fats contain omega-6 and omega-3 unsaturated fatty acids. The first is in most vegetable oils, and the second is in fish, as well as in soybean and rapeseed oils.
