What components do leeks have?

Like onions and garlic, leeks are rich in sulfur compounds, especially allicin, which give them their antibacterial, circulatory and diuretic properties.

Leeks are a good natural antibiotic, very suitable for eliminating the microorganisms that cause many intestinal diseases.

Eating leeks in abundance will help improve bowel conditions and prevent abnormalities such as intestinal rottenness causing flatulence, diarrhea, etc.

On the other hand, its richness in selenium helps to strengthen the defenses, constituting one of the foods that most protect against the appearance of contagious diseases.

Leek is a vegetable that helps improve circulation

The sulfur compounds of the leek have fluidifying properties of the blood. Components as important as alliin and ajoene help the body to avoid the appearance of thrombi or clots. By improving blood circulation, the intake of leeks is suitable for those with a number of circulatory diseases related to poor circulation: obesity, diabetes, cholesterol, angina pectoris, myocardial infarctions, etc. (In these cases, it is also recommended to reduce foods with lots of salt and foods with a lot of saturated fat).

On the other hand, its richness in zinc can help contribute to the fight against the degeneration of the walls of the arteries, which, together with its ability to dilute the blood, makes it one of the most suitable foods in the prevention of diseases of the veins, such as varicose veins and hemorrhoids.

For all this, it is very interesting to eat leeks in abundance, but especially as we get older and our blood vessels suffer the excesses over the years and the results of inappropriate food and vital habits.

Eating leeks helps lower cholesterol and triglycerides

It has been proven that diets based on an abundance of vegetables such as leeks can help lower triglycerides and cholesterol levels, helping to keep the arteries in better condition and prevent vascular accidents related to high levels of bad cholesterol (LDL cholesterol) in the blood.

Leeks can help treat constipation

Its mucilage content gives it adequate properties for the treatment of constipation. Its fermentative fiber is susceptible to being fermented by the bacteria of the colon and helps to increase the microbiota or healthy bacterial fermentative flora, related to the prevention of colon cancer.

In this way, the leeks, for their already mentioned antibacterial properties, their fermentative property and their slight laxative effect, are positioned as one of the most suitable foods in the health of the intestines.

Leek is a good diuretic

For its principles with diuretic properties, leeks promote the elimination of body fluids. This property is widely used to help increase urine and elimination of substances in case of obesity, and fluid retention due to rheumatism, arthritis or gout. Its sulfur content gives it this characteristic of diuretic food to increase the elimination of metabolic waste.

An abundant urination will also help during the treatment of urinary diseases and for the prevention of kidney stones. It is also recommended for consumption in liver cleansing, depurative, slimming diets, etc.

Due to its high potassium content, leek is an excellent food to accompany meats, fish and foods rich in sodium, because it balances excess salt in the diet and facilitates its elimination. This food is recommended for people with hypertension.
