Which dairy products are the most useful – a scientific review of 14 types

Dairy products are spread all over the globe and have been part of the human diet for more than 5,000 years.

They contain a lot of valuable amino acids, vitamins, micro- and macroelements that improve the course of digestive processes, strengthen the immune system, prevent the appearance of endocrine and cardiovascular diseases.

However, these products have contraindications that are extremely common among the population (allergic reactions, lactose intolerance, etc.).

In this article, we will look at the proven beneficial properties of various types of dairy products. At the end of the article, we will try to conclude which of them is more useful and preferable for use.

Types of dairy products

The following groups are distinguished:

  1. Drinking milk.
  2. Milk separation products (cream, butter, whey).
  3. Fermented milk products . They are produced by fermenting milk by microorganisms. The type of fermentation is lactic acid. This group includes: sour cream, cheese, cottage cheese, ayran.
  4. Mixed fermentation products. They are obtained during the simultaneous course of alcoholic and lactic acid fermentation, and contain a small amount of ethanol. The most striking example is kefir.
  5. Cheeses.
  6. Canned milk (condensed milk with sugar, dry dairy products). This group of substances has practically no value and can be harmful to the human body.
  7. Ice cream.

All dairy products have many useful properties: they help strengthen skeletal tissues, restore impaired digestive functions, maintain immunity, and prevent a number of oncological and cardiological diseases.

Milk-based products can also have a negative effect on the body. The mechanisms are caused by various reasons: from individual hypersensitivity or ethnicity to production technology.

However, there are differences between different types of products, which we will discuss below.

Overview of the properties of 14 specific products

Below we will look at a list of the 14 most common dairy and fermented milk products, describe their medicinal properties and possible side effects.
