Discover the Magical Health Benefits of Garlic

Introducing Garlic: A wonder spice


Garlic is scientifically known as Allium sativum and is used both as food, typically as a spice, and medicine. It is a natural cure for many infections, cardiovascular problems and diabetes. The use of garlic can be dated back to the time of Egyptian pyramids. Recent research has also shown the potent action of garlic in deadly disease like cancer. It is rich in antioxidants and its regular consumption, in moderate quantities, reduces the risk of cancer.

Nutritional Value of Garlic

  • Consumption of garlic adds to less number of calories and it is rich in some vital vitamins and minerals like pyridoxine (vitamin B6), vitamin C, vitamin B1, copper, manganese, selenium, calcium and phosphorus.
  • A daily consumption of 100 gm of garlic fulfills the dietary requirement of all major nutrients within our body.
  • Garlic is rich in sulfur-containing compounds like thiosulfinates, sulfoxides and dithiins. These compounds are responsible for the number of health benefits associated with garlic.

How does garlic help the body fight against cancer?

  • The anti-carcinogenic property of garlic is largely related to the presence of organosulfur compounds like - Diallyl sulfide. The strong taste and odor of garlic is due to Diallyl sulfide which has the potency to both inhibit and induce the P-450 enzymes selectively. Flavonoids present in garlic stimulate the antioxidant properties. Its consumption has shown most effective results in case of renal cell and colorectal cancers. In fact, it shows beneficiary effect in almost all kinds of cancers, except prostate and breast cancers [1].
  • Allicin derived from garlic stimulates the process of apoptosis and hence anti-tumoral activity in Lymphoma-bearing mice. The process of apoptosis was stimulated by the increased caspase-3 activity [2].
  • Nitrobenzene is an organic chemical which is considered to be carcinogenic to human beings. It is used in pesticides, dyes, rubber etc. This chemical has the potential to damage DNA. Garlic squeeze can control this chemical-induced cancer [3].
  • A regular consumption of allium vegetables including garlic, onions and leeks reduces the risk of gastric cancer [4].

Some More Health Benefits of Garlic

  • Garlic stimulates hypoglycemic effects in Type II diabetes patients.
  • When administered along with anti-diabetic medicines like Metformin, it decreases the levels of blood sugar and bad cholesterol (LDL and triglycerides). In addition, the levels of HDL (good cholesterol) are increased significantly [5]. This makes garlic the best dietary substance for diabetics and cardiovascular patients.
  • The reactive oxygen species and free radicals generated within our body damage the inner lining of the blood vessels. Allyl polysulfides present in garlic control this damage caused by the oxidative stress.
  • High levels of vitamin B6 reduce the levels of homocysteine which damage the blood vessels. The anti-inflammatory properties of garlic also help the respiratory and musculoskeletal system. Its consumption is advised to patients suffering from arthritis and asthma.
  • The antibacterial properties of garlic are noticed by its potent action against Helicobacter pylori, which causes ulcers in the stomach [6].

The Best Way to Include Garlic in Our Diet


It is recommended to include at least one serving of allium vegetables in our diet daily. It is good to consume garlic in the raw form, either chopped or pressed, to get the optimum health benefits. The process of chopping favors the enzymatic conversion of alliin into allicin. People who eat rice as a staple food can leave 1or 2 cloves of chopped garlic on the cooked rice for few minutes and later consume them. If one cannot tolerate the strong odor of garlic, they can add them to curries at the end of cooking so that the nutritive value is preserved. It is always advisable to take garlic cloves in the chopped form rather than consuming them as a whole. Moreover, it is good to leave the chopped garlic cloves for a span of 10 minutes before subjecting to boiling or cooking. This enhances the beneficial properties of alliinase enzyme.
