Which is healthier, black pork or white pork?

The main difference between black pork and white pork is that they live in different species. White pork is our domestic pig, and it is also the main source of pork for people to eat.

White pork is high in fat and is often used in cooking a variety of meats.

Generally speaking, the color of black pork is bright red, and the amino acid content of black pork is much higher than that of white pork, among which threonine and alanine are very high. Therefore, black pork tastes better and keeps longer.

In terms of meat quality and nutrition, black pigs are obviously better. Black pork has strong elasticity and rich and mellow cooked meat flavor. Feed-fed white pork has poor elasticity and poor taste.

But when you buy it in the market, the price of black pork is three times that of white pork, and many people can easily buy fake black pork and spend money in vain.

Although eating black pork is rich in nutrition, if you only eat it once in a while, there is not much difference in nutrition.
