April 19 was National Garlic Day and we just had to share with everyone the important benefits of this vegetable.

Garlic (Allium sativum) is widely used around the world for its pungent flavor as a seasoning or condiment. From history, it is known that garlic has been used for more than 7,000 years by humans. Originally the plant was native to central Asia, but it has long been used for consumption (raw or cooked) as seasoning in many other parts of the world such as the Mediterranean region, Africa, and Europe.

The composition of the bulbs is approximately 84.09% water, 13.38% organic matter, and 1.53% inorganic matter, while the leaves are 87.14% water, 11.27% organic matter, and 1.59% inorganic matter. The organic matter is mostly carbohydrates while the inorganic matter is compounds such as Sulphur and iron. The large number of sulfur compounds contributes to the smell and taste of garlic. Allicin has been found to be the compound most responsible for the “hot” sensation of raw garlic.

Let’s now go on to talk about nutritional value and health benefits of garlic

A. Nutritional Value

In the typical serving size of 1–3 cloves (3–9 g), garlic provides no significant nutritional value with the content of all essential nutrients below 10% of the Daily Value (DV), but when expressed per 100 grams, garlic contains several nutrients in rich amounts (> 20% DV), including vitamins B6 and C, and the dietary minerals, manganese and phosphorus.

Per 100 gram serving, garlic is also a good source (10–19% DV) of certain B vitamins including thiamine (Vitamin B1), and pantothenic acid (Vitamin B5), as well as certain dietary minerals including calcium, iron, and zinc.

B. Health Benefits

We all know garlic is commonly used to add flavor to many food dishes, but it has some impressive health benefits too. The key medicinal compound in garlic which is ALLICIN has antibacterial, antiviral, antifungal and antioxidant properties.

In addition, garlic is packed with vitamins and nutrients. Some of these include vitamins B1, B6, C, as well as manganese calcium, copper, selenium and many others.

A little garlic every day can go a long way in helping you to protect, as well as boost, your health. To reap the most health benefits from garlic, eat it in its raw state. Cooked garlic loses a significant amount of its medicinal qualities.

7. Aids Digestion

However, garlic should not be taken in excess though, as it may irritate the digestive tract and cause heartburn.
