Rumors: There are many news about Pork on the Internet: “The oldest old man in Jiangsu is 115 years old. Its secret of longevity is to eat braised pork for three meals a day.†A Diet and Habits for 40 Hundreds of Old People in Beijing The survey found that 30 people are particularly fond of red meat and eat almost every day. However, these elderly people have low levels of triglycerides and cholesterol and have not been found to have high blood lipids, atherosclerosis, coronary heart disease, or diabetes. Longevity elderly people love to eat Pork, eat braised meat really live it?
Saturated fatty acids in stewed pork are significantly reduced
Pork is a traditional Chinese dish that is loved by everyone. Pork is generally pork-based material, ingredients are soy sauce, soy sauce, sugar, rice wine, etc., but because of different tastes, Pork Pork practice, ingredient composition and proportion are also different.
Gu Weigang et al. of Zhejiang University discovered that braised pork has changed some components of pork during cooking. Studies have shown that raw pork fat has the highest content of saturated fatty acids (42%), followed by monounsaturated fatty acids (29.8%) and polyunsaturated fatty acids (28.2%); oleic acid, linoleic acid, palmitic acid and stearic acid are The main fatty acids in the raw meat account for 84.74% of all fatty acids. The ratio of monounsaturated fatty acids was significantly increased after the raw meat had been steamed and boiled, and monounsaturated fatty acids became the main fatty acid (48.08%) after stewing for two hours, while the saturated fatty acids in the raw meat were significantly reduced.
19 types of fat related to family longevity
When we searched for information on diet and longevity-related topics on the medical website, the research that jumped us out was no stranger to us. For example, Japan's Okinawa has a large number of elderly people with a longevity of 100 years old. Their dietary structure mainly comes from the dietary habits of ancient China and combines the characteristics of local resources. Pork, fish, kelp, and tofu are almost common foods on the table. In 2005, Italian researcher Solfrizzi V reported a prospective cohort study with a median of 6.5 years, and 704 elderly people aged 65-84 years were studied. Under the premise of a typical Mediterranean diet, the intake of higher monounsaturated fatty acids in the diet prolongs survival, and the increase in the ratio of unsaturated fatty acids to saturated fatty acids slightly increases total mortality.
An 18-year study by the Harvard School of Public and Health published in the journal “Circulation†in 2008 showed that vegetables, fruits, whole grains, and pork are defined as relatively strict and stressful eating behavior. The former had a lower incidence of cardiovascular disease and lower overall mortality. The results of a study published by researchers in the Netherlands in 2013 are also quite interesting. After 90 days of longevity, the fat metabolism of their offspring is also more special than that of normal controls. The 19 types of fat are associated with familial longevity, and the proportion of monounsaturated fatty acids and polyunsaturated fatty acids in the blood of the progeny of longevity women is relatively high. Therefore, it is less likely to cause oxidative stress.
Eating pork and longevity may not be directly related
The previously considered red meat is a superposition of simple sugars and saturated fatty acids. Now it seems to be completely different from the scientific verification. For the dish with red meat, close to 50% of the monounsaturated fatty acids are unchanged under different cooking conditions and different raw materials. Even if the content of monounsaturated fatty acids in braised pork is enough to affect a person's lifespan, I think it may not necessarily happen. As stated in the scientific search, dietary structure, family longevity, genetic superiority, and living habits have direct and indirect effects on longevity. If you want to draw a definitive conclusion, you need to exclude large numbers of people from other groups. After the interference of various conditions, scientific and objective research methods can be used to draw a conclusion that pork is directly related to longevity.

Patients with chronic diseases should not eat red meat
Pork is an indispensable animal food on the table of most families. It is rich in high-quality protein and essential fatty acids, and provides nutrients such as iron and calcium that are beneficial to the body's absorption. Chinese medicine believes that pork is flat and sweet, and it has the effects of gastrointestinal, fluid, kidney and antipyretic drugs. However, due to the high content of saturated fat and cholesterol in pork, especially pork, and the need to add a certain amount of sugar when cooking braised pork, dietitians usually do not recommend regular consumption of people with diabetes, obesity, and high blood lipids.
