The liver is an organ for detoxifying and filtering, and the feed that pigs eat in the feeding process will contain some toxic substances, and these toxic substances may also reside in the pig liver. Therefore, the pork liver you bought now must not be washed casually before you start eating. You must first clean it with clear water, then put it in water and soak it for half an hour before you can start cooking. Avoid eating too much at one time

Although the nutritional value of pig liver is high, the visceral parts of animals contain quite high cholesterol content, which may lead to an increase in cholesterol if eaten in excess at one time. Especially for patients with "three highs", we should try our best to reduce consumption, otherwise it may aggravate physical illness.

Avoid short cooking time.

The eggs of bacteria and parasites are hidden in pig liver. In the cooking process, they must be heated for enough time before they can be killed. However, many people pursue it. Avoid eating with vitamin C.

Among the nutritional components of pig liver, the content of copper is very high. However, once copper meets vitamin C, vitamin C will be rapidly oxidized and lose its function. Therefore, it is forbidden to eat vitamin C together for some time before and after eating pig liver. Even if you eat it, vitamin C can't play its role.
