For a long time, many people always associate eating fat with hypertension, coronary heart disease and obesity. It seems that eating fat is the chief culprit of these diseases. Even some elderly friends with hyperlipidemia don't even eat a little fatter meat. In fact, this is a misunderstanding of fat meat. When we say fat meat, we mainly refer to pig fat meat, such as pork belly and elbow meat. Nutritionally speaking, eating these fats properly is not only harmless to the body, but also beneficial to human health. Especially the elderly often eat cooked fat (stew for about an hour), which can also reduce blood fat, blood pressure and cholesterol, eliminate diseases and prolong life, and improve intelligence and beauty. A survey of the eating habits of dozens of centenarians in Japan shows that besides work, activity and optimism, most of the longevity elders like to eat stewed fat pork. Moreover, these elderly people have no hypertension, coronary heart disease, obesity or arteriosclerosis. Later, experts pointed out through experiments that the content of saturated fatty acids in pork decreased greatly with the increase of stewing time of fat meat, and the fat meat stewing for more than one hour could decrease by 46.5% to the lowest point. Monounsaturated fatty acids and polyunsaturated fatty acids are added continuously with the increase of cooking time, reaching the highest value in a short time. This is equivalent to transforming the unfavorable elements (saturated fatty acids and cholesterol) in fat meat into powerful elements (monounsaturated fatty acids and polyunsaturated fatty acids). At the same time, the stewed fat meat retains the original nutritional components of pork (rich in vitamin B 1, protein and essential fatty acids), and the gelatinous part is more easily digested and absorbed by human body. Therefore, it is especially suitable for the elderly. When buying pork in the market, residents should choose pork with bright color and bright red, which feels fine and dense, and is called slightly dry or slightly wet and not sticky. After gravure printing, it can recover quickly and smell pork without fishy smell. When cooking this kind of slightly fat pork for the elderly at home, it is best to stew it in a sealed pressure cooker to make it more cooked and rotten. In practice, fat pork can be made into various dishes, such as white meat, white meat with sauerkraut, braised pork belly, braised pork, white meat with garlic paste and so on. More, more
