The whiter the pork skin, the more nutritious?

Many women think that pig skin, also known as pig skin, is white and clean and safe. Can you please advise on how to choose the right skin? (Xuan, 29 years old, Hanoi ).

Pork skin is a popular dish, rich in protein, vitamins, and minerals for the body, but you should not eat too much. The skin contains a lot of cholesterol, which is not good for people who are overweight, obese, or have high blood fat. People with gout or kidney failure should also limit it.

Normally, clean leather is pinkish white, while other pure white leather can be contaminated with chemicals during the cleaning and washing process.

Currently, many establishments use chemicals to bleach the skin, giving it a beautiful color. These detergents only whiten the skin but cannot kill all bacteria, larvae, and pathogens. During the collection and transportation process, pig skin is also susceptible to spoilage and rot, and after being bleached with chemicals, it is difficult to distinguish with the naked eye. If eaten regularly, there is a risk of accumulating aflatoxin in the body, causing poisoning. Mild cases cause diarrhea, abdominal pain, nausea; more severe cases can cause gastrointestinal diseases and even cancer.

To ensure safety, you should choose pigs with clear origin and source to avoid bacterial contamination or dangerous pathogens. Do not choose skin that is too bright white. Clean pig skin is usually crispier and tougher, without a foul smell.
