According to the “China Consumer Daily†report, “live and eat†seems to be fashionable nowadays. Many people think that this will make nutrition more delicious and taste more delicious. The Japanese used sashimi as a delicacy, and some people even raised live snakes, live frogs, and live birds. In fact, everything cannot be absolute, and “raw food†cannot be promoted as a dietary habit.
Live fish eat fresh fish is not fresh enough to absorb nutrients
In the eyes of the average person, live fish is delicious, and then "live fish live" is regarded as the best way to eat. However, some nutritionists believe that cooking fresh fish or fresh fish is not the best choice, regardless of nutritional value or taste. Experts point out that fish, like other animals, continue to undergo stiff, autolytic, and rancid Biochemical reactions after death. After the fish died, the muscles became stiff. In the rigid stage of the fish, the protein in the muscle tissue has not yet been broken down into amino acids. At this time, the fish burned are harder and less tender and the nutrients are not easily absorbed by the body. After a high degree of rigidity, the fish body begins to soften. This is the autolysis phase. At this stage, the protease in the fish body gradually decomposes the protein into a variety of amino acids easily absorbed by the human body. At this time, the fish is soft and easy to digest and absorb after eating. The taste is also the most delicious.
The time from the hardening of the fish to the self-dissolving process depends on the ambient temperature. The higher the outside temperature, the shorter the time. In general, 2 to 3 hours in the summer and 4 to 5 hours in the winter, you can cook and eat.
Raw shrimps and crab parasites invade the body and cause lesions
Now people seem to have tired of cooked chicken, duck, fish, and relatives and friends always like to eat some drunk shrimp, crabs and other food. However, when you eat raw food such as fish, crabs and shellfish, parasitic parasites parasitizing on fish and shrimps will stink into your tissues and organs.
Some people think that as long as fish and shrimp before eating, add some wine, salt, soy sauce, vinegar and other condiments, you can kill the parasite capsule, not to mention after eating, but also after the digestion of acidic gastric juice, raw food anyway. However, after several experiments by scientists, the method described above cannot completely kill the capsular sacrum, and nearly half of the capsular worms still survive.
The common parasitic disease is liver flukes, which means that people eat freshwater fish and shrimp and get infected with liver flukes. Once a person takes a capsule, it can develop into an adult in the human body, invading tissues and organs, causing lesions and various symptoms. In order to prevent raw fish and shrimp from damaging their health, people must change the eating habits of eating raw fish, live shrimp or half-cooked aquatic animals. Fish and shrimp must be cooked before cooking.
Mutton is too tender to infect parasites and even cause meningitis
To eat mutton, many people like to only mature until July 8th, which is very easy to be infected with trichinosis. In the small intestine of the sheep, the adult of T. spiralis is often parasitized, and the larvae of T. spiralis are often parasitized in the diaphragm, tongue muscle and muscle. If you eat too much mutton meat, the live larvae of Trichinella spiralis enter the body. These larvae enter the bloodstream, travel around the body, and finally settle in muscles, causing nausea, vomiting, diarrhea, high fever, headache, muscle pain, and severe pain in the abdomen and stomach. Restricted movement, etc.; larvae can also cause symptoms of meningitis if they enter the brain and spinal cord.
Raw eggs destroy the body's digestion and absorption

In fact, raw eggs contain "avidin" and "anti-trypsin," the former can affect the body's absorption and utilization of protein, which can destroy the body's digestive function, so eggs should be cooked to eat.
