Garlic is a member of the lily or Allium family. It is rich in a variety of sulfur-containing compounds- thiosulfinates, sulfoxides, and dithiins. Despite being the source of garlic’s pungent odor, they are also the source of its health-promoting contributions in the community. Aside from sulfur that is important in our health, garlic also contains manganese, selenium, Vitamin B6 and Vitamin C.

Cardiovascular Benefits

Garlic is able to moderately decrease blood triglycerides and cholesterol. Despite this test running on garlic oil, garlic powder or garlic extracts instead of the actual food form, we can’t disregard the fact of this benefit.

Oxidative stress is also two major causes of cardiovascular problems which can increase risks of heart attacks and atherosclerosis. Inflammation on the other hand can cause clogging in the blood vessels and plaque formations. Garlic’s sulfur-containing compounds helps protect us from oxidative stress and inflammation. Ajoene is the particular disulfide responsible for keeping platelets in check, thus, preventing it from becoming too sticky. This lowers the risk of the platelets clumping together forming a clot .

Allicin from aliin in garlic blocks angiotensin II activities by preventing it from the contractions of blood vessels and lowering our blood pressure in the process.

Selenium and manganese found in garlic serves as a cofactor as antioxidant enzymes of the body.

Anti-inflammatory Benefits

In animal studies, aged garlic extracts have shown characteristics to reduce and help moderate and improve inflammation from certain body parts. Anti-arthritic compounds are foundindiallyl sulfide (DAS) and thiacremonone.

Body’s fat cells (adipocytes) which are related to inflammation cannot develop fully if they cannot progress from the preliminary stage called pre-adipocytes. 1,2, -vinyldithiin, or 1,2-DT is a sulfur compound found in garlic that lessens the conversion of pre-adipocytes to its final developed form of adipocytes.

Antibacterial and Antiviral Benefits

Fresh garlic extracts and powdered garlics undergone researches that promotes garlic’s medical standpoint. Bacteria and viruses can be controlledby the presence of garlic. And not only that, but also infection from yeasts or fungi and even worms.

Crushed garlic even helps prevent infection caused by the bacterium Pseudomonas aeruginosa from burn patients. For bacterias that have become resistant and tolerant of antibiotics, garlic is also able to treat bacterial infections from such. Garlic also helps regulate the body’s response to infection caused by the bacterium Helicobacter pylori that is a factor for ulcer.

Cancer Prevention Benefits

Cancer is one of the most deadly diseases from a lot of countries. And surprisingly, our kitchen ingredient garlic has anti-cancer components.

Daily intake of garlic lowers risks of all cancer types except for prostate cancer and breast cancer. Several intakes per week on the other hand lowers risks of colorectal and renal cancer. Garlic has a consistent record of anti-cancer benefits.

One of the key components found in garlic that plays a major impact in its anti-cancer benefits is the allyl sulfides. These compounds can activate nuclear erythroid factor (Nrf2), a molecule found in the main cells. When Nrf2 transfers to the cell nucleus, it triggers several metabolic activities. This event prepares the cells for engagement for strong survival response, such as in oxidative stress, or in some cases, programmed cell death or apoptosis. Nrf2 suggests that garlic helps cell respond to prevent develop cancerous cells from the body.

Iron Metabolism

Ferroportin is a protein that helps iron return to circulation. It runs across cell membranes and assists the stored iron to leave the cell. Garlic is able to increase the body’s production of ferroportin that makes the circulation of iron easier for the body as needed.

One done, placing the garlic ‘cheeks’ side down and applying pressure with the flat side of a knife can ‘loosen’ up the skin, abling you to easily remove it with your fingers or small knife.
  • Chopping garlic enables its enzymatic process that creates allicin. The compound where most of garlic’s health benefits come from. For maximum production of this compound, it’s best to let it sit for a few minutes before cooking or adding acidic ingredients like lemon juice
  • Since chopping garlic activates the enzymatic process of garlic, it is recommended to crush or chop it first before microwaving or cooking as whole cloves can deactivate its enzymes through heating.
