Scientists have refuted the widespread belief that fresh vegetables and fruits are much healthier and more nutritious than canned and frozen.
As shown by studies of Chester University,the percentage of nutrients sometimes in these products than in fresh, writes the Daily Mail.
The researchers compared the level of vitamin C in raspberries, pineapples, sweet corn, carrots and peas and found little difference between fresh or frozen raspberries.
In some cases, frozen varieties do contain a lot more vitamins.
From all the studied samples the highest level of vitamin C contained frozen raspberries and peas, and a minimum of fresh raspberries.
There was no noticeable difference between the frozen and fresh pineapple, however, the level of zinc and magnesium was higher than canned. The same can be said about carrots.
As for corn, the most vitamins, it was fresh, for it is canned and frozen.
As explained by the researchers, often fresh products are transported over large distances and long time lie in warehouses and supermarket shelves.
In some cases, fresh apples and potatoes are harvested, and then about a year nizkokalorina stored in the refrigerator to slow the ripening process and damage.
Nutrients contained in fresh fruits and vegetables are gradually destroyed with time. But if such products are quickly frozen or canned, these useful vitamins and minerals can be stored for a longer period.
“Frozen and canned products also contains a decent set of nutrients,” says nutritionist Charlotte Stirling-reed.
