Sweet and sour leeks
The leek can be defined as a close relative of onions and garlic, both for the content of useful nutrients and for the absolutely unmistakable flavor and is part of the same family: the alliaceae.
Like garlic and onion and shallot, the substance that gives the typical smell and above all the incredible beneficial properties for our health is the same: allyl sulphide.
Leek is referred to as an anticancer feed. It was also traditionally used in the kitchen as a diuretic and purifying food.
Thanks to these properties, it is used for healing in cases of obesity, kidney inflammation, gout and to combat dyslipidemias (high cholesterol).
Now its beneficial properties for our body have been re-evaluated.
It is considered an instant anti-cancer food like onions and garlic. The presence of allyl, the active ingredient in leeks, together with the flavonoids present in the plant also have a beneficial action on blood circulation that can reduce the risk of cardiovascular disease.
Recent studies have also verified its usefulness in the prevention of hip osteoarthritis.
Other nutritional properties of leek: vitamins and fibers useful for intestinal regularity.
Leek is an excellent dietary source of vitamin C, folic acid and beta-carotene. It is also rich in dietary fiber useful for constipation. In this regard, we specify that the most useful fibers for regulating the intestine and fighting constipation are those contained in the white part. The fibers contained in the green part are heavier to metabolize and it is for this reason that the bulb and only the white part of the leek is used.
Like onion and garlic, leek has an antibacterial and antiseptic action.
