1. Choose healthy pig liver.
When selecting pig livers, you should choose pig livers that have passed quarantine inspection, and livestock livers that have died or died of unknown causes are inedible. Healthy pig liver is reddish brown, smooth and shiny, soft and tender. Fingers can be inserted into the incision with a little force, and it tastes fresh when cooked.
2. Wash pig liver thoroughly
Pig liver is the largest organ for transferring and detoxifying poisons in pigs, so it should be thoroughly cleaned before eating it. Rinse the pig liver in tap water for a few minutes, then soak it in cold water for 30 minutes, and finally take it out and clean it in clean water. If you need to eat it immediately, you can cut the pig liver into small pieces, gently wash it with your hands in clean water, and then rinse it under tap water.
3. Master reasonable cooking time.
The cooking time should not be too short, and the pork liver should be cooked before eating. Don't "fry quickly and thoroughly" when cooking, and don't "cook" for freshness. Be sure to cook and fry the pig liver thoroughly, so that the pig liver is completely grayish brown and can't see bleeding silk, so as to ensure food safety.
4. pig liver is not eaten with vitamin C.
Pig liver is rich in trace elements such as zinc, manganese and copper. If it is eaten together with vitamin C tablets or foods with high vitamin content, a chemical reaction will occur, and vitamin C will be oxidized into dehydroascorbic acid and lose its normal efficacy, resulting in the reduction of nutrients in food, which is not conducive to the absorption and utilization of vitamins by the human body.
5. Eat less foods containing fatty acids.
When eating pig liver, you should eat less other foods with high saturated fatty acids, such as animal oil, fat, cream, butter, whole milk and so on. In order to prevent saturated fatty acids in these foods from promoting the absorption of cholesterol in pig liver and reducing the harm of cholesterol in pig liver to health.
6. Soybeans are healthier
While eating pig liver, you can eat some soybeans and bean products properly. Because the structure of stigmasterol contained in soybeans is similar to cholesterol, it can compete with cholesterol in the intestine, which will reduce the absorption of cholesterol in pig liver, so it is healthier to eat together.
7. Control the consumption of pig liver
A person's daily intake of cholesterol from food should not exceed 300 mg, and the cholesterol in every 100 g of fresh pig liver can reach more than 400 mg. Therefore, patients with hypertension and coronary heart disease had better not eat pig liver. Healthy adults eat 50 ~100g twice a week, which can not only meet the body's demand for iron and vitamin A, but also lead to excessive cholesterol intake.
8. Warm reminder
Pig liver and spinach can complement each other. The liver is the detoxification organ in the body, which inevitably stores some toxic components. Spinach contains a lot of vitamins and cellulose, which can just solve the residual toxicity of liver. In addition, pork liver with spinach fully embodies the characteristics of "meat and vegetable collocation" in China's diet.
