What kind of cheese is the healthiest? Distinguish natural cheese from processed cheese.

Faced with a wide variety of cheese, how to choose? Cheese, also known as cheese, can be divided into soft, semi-hard, hard or super-hard cheese according to its water content; According to processing technology, it can be divided into natural cheese and processed cheese. Natural cheese is directly processed from milk, while processed cheese is made from cheese with water, butter and other raw materials through heating, stirring and emulsification. From the packaging point of view, there are generally only four kinds of raw materials on the ingredient list of natural cheese: pasteurized milk, lactic acid bacteria (specific strains depend on the product), rennet and edible salt. In addition to cheese, processed cheese also contains butter, sugar and other ingredients. Therefore, consumers should first choose natural cheese because it has high calcium content and few additives. However, most of the cheese on the market now belongs to processed cheese, and consumers should look at the nutrient composition table when choosing. Protein and those with high calcium content and low fat and sodium content are healthier. It is worth reminding that not all products with the word "cheese" contain cheese ingredients. You should make sure that there is the word "cheese" in the product ingredient list, and the higher the position, the better, and it is best to rank first.
