1. Stabilizes Blood Pressure
Mature garlic extract contains a bioactive sulfur compound, S-allylcysteine, which has been found to effectively lower blood pressure by 10 mmHg (systolic pressure) and 8 mmHg (diastolic pressure). Sulfur deficiency is one of the reasons for high blood pressure and therefore supplementing the body with organosulfur compounds can help stabilize blood pressure (7). Heat treatment tends to destroy allicin.
2. Lowering LDL cholesterol
American scientists found that aged garlic extract supplement can help lower LDL cholesterol by 10% in hypercholesterolemic male human participants. In rats, garlic inhibited the synthesis of cholesterol in liver cells. The researchers further experimented with water soluble and lipid soluble compounds of garlic and found that water soluble compounds in garlic inhibited cholesterol synthesis by 20-60% .
3. Prevents Cardiovascular Diseases
Scientists have evidence that garlic can help prevent lmost all cardiovascular diseases. It helps to prevent cardiovascular diseases by lowering bad cholesterol, lipid, and serum triglyceride increase antioxidant activities, and decrease platelet aggregation. Garlic was also found to be effective against atherosclerosis.
4. Improve Bone Health
Age and unhealthy lifestyle can make your bones weak, which means that fractures and osteoporosis will set in much earlier. Garlic has been found to be effective against osteoporosis and arthritis. In a study, scientists supplemented lab rats with garlic oil and found that garlic oil was able to suppress ovariectomy-induced bone resorption (11). Another group of researchers concluded that the diallyl disulfide helps to suppress the matrix degrading enzymes and therefore prevents damage to the bones.
5. Relieves Intestinal Ailments
An upset stomach or a broken digestive system can hamper your daily life. So, if you are suffering from intestinal problems, you might want to consume garlic. Garlic tends to differentiate between the good and bad gut bacteria in the intestine and has an antibacterial effect on harmful enterobacteria (13). Scientists have also found that garlic is effective against H. pylori infections.
6. Regulates Blood Sugar
High blood sugar can make you prone to developing diabetes, blood pressure, obesity etc. If you are suffering from high blood sugar, you must include garlic in your diet. Scientists from Kuwait conducted an experiment with raw and boiled garlic and found that raw garlic significantly reduced blood glucose levels in lab animal models (15). Therefore, consume raw garlic instead of the cooked bulb to help lower the blood sugar levels.
7. Prevents Thromboembolism
Clotting of blood to prevent excess blood loss is good but not when the blood clots detach and are carried by the bloodstream to other vital organs such as brain, lungs, kidney etc. Indian scientists experimented with garlic. The participants were asked to consume 10 mg raw garlic every day before breakfast for two months. The study concluded that garlic could be used to prevent thromboembolism.
8. Helps Fight Cancer
Garlic contains diallylsulfide that helps inhibit oxidative stress, selenium present in garlic is known to have cancer-fighting properties, prevents DNA mutation and uncontrolled cell proliferation, and metastasis (17). A clinical trial conducted by Chinese scientists on cancer patients found that garlic lowered the chances of tumor formation by 33% and reduced stomach cancer by 52% (18). So, if you want to lower the risk of cancer, consume garlic along with leading a healthy lifestyle.
9. Strengthens Immune System
Garlic contains phytonutrients that are antioxidant in nature. Antioxidants flush out toxins and reduce oxidative stress in the body, which prevents you from falling sick or being prone to DNA mutations and disrupted cell functions. Researchers have also found that supplementing with garlic helped increase different types of immune cells in the body.
10. Relieves Oxidative stress
As I mentioned earlier, garlic can help relieve oxidative stress. The water soluble organosulfur compounds found in garlic can help prevent DNA damage, reduce inflammation and atherosclerosis risk due to oxidative stress. In fact, garlic can also help prevent heart diseases by nullifying harmful free oxygen radicals.
