It is believed that vegetables and fruits, berries and greens can provide the body with all the necessary nutrients.
To maintain health, they are recommended to be consumed fresh. But there are exceptions.
Scientists have listed products that retain their benefits even after canning and freezing.
According to researchers from the British National Centre for Health, there are four such products.
First of all, these are tomatoes.
This is the main source of lycopene, as well as calcium and iron. But canned and heat-treated tomatoes contain significantly more of these substances than fresh ones.
Secondly, it's blueberries.
For long-term storage, it is recommended to freeze the berry. In this form, it retains the maximum amount of vitamin C and polyphenols.
The berry remains no less useful than fresh due to the fact that freezing slows down the loss of useful elements.
Thirdly, it is peas.
People are used to eating it fresh or canned, but freezing makes peas healthier.
It contains more B vitamins and vitamin E than fresh peas.
Fourth, spinach
Fresh spinach is healthy, but after freezing it retains vitamin E and iron, and at the same time spinach is easily absorbed by the body.
