Where is vitamin A?

The next 15-20 minutes will be devoted to the conversation about the firstopen vitamin scientists - it's vitamin A. It's no coincidence that he got his name from the first letter of the alphabet. We will discuss what forms of this vitamin exist, where vitamin A is contained, how to keep it in products and increase the probability of assimilation.

Vitamin A and its forms

And the forms are distinguished by two:

  1. Retinol is actually vitamin A in its original form;
  2. Carotene is a provitamin A, which is not a vitamin in nature, but it transforms into it as soon as it enters the human body.

Vitamin A refers to fat-soluble vitamins,which means the need for a certain (adequate) amount of fat, as well as other minerals (beta-carotene, for example) for its successful assimilation. Fat solubility means that this vitamin does not dissolve in water. Then you will see that vitamin A is found in animal and plant foods. If the animal food already has a sufficient amount of fat, then the vegetable is poor. What does it mean? To assimilate vitamin A from plant products (in particular, from fruits and vegetables) it is necessary to consume them with a certain amount of fat (with vegetable oil, sour cream, yogurt).

A certain part of vitamin A is destroyed whenwatering products with boiling water, while cooking and preserving. If vitamin A is preserved during heat treatment, it can further collapse, being in prolonged contact with oxygen.
