7 Health Benefits of Garlic

Some “immunity shots” incorporate garlic, and for good reason. Historically, garlic has been used to ward off illnesses, fight infections, and treat wounds. In fact, research lends credibility to garlic’s immune-bolstering capabilities. In one study, https://www.ncbi.nlm.nih.gov/pubmed/11697022 146 volunteers were assigned to receive either a placebo or a garlic supplement daily for 12 weeks throughout the winter. The garlic group experienced significantly fewer colds compared to the placebo group, and they recovered faster if they did get infected.

Newer research confirms that aged garlic extract may enhance immune cell function. In the study, healthy adults between 21 and 50 received either a placebo or aged garlic extract for 90 days. While there was no difference in the number of illnesses between the groups, those who received garlic had reduced cold and flu severity, fewer symptoms, and a smaller number of missed days of work or school.

It can boost heart health

In a recent review of previously published studies, scientists summarized the many ways garlic protects heart health. These include lowering blood pressure and cholesterol, as well as reducing artery stiffness and blood markers for inflammation. Other research shows that compared to a placebo, aged garlic extract can help slow the rate of progression of coronary artery calcification, a risk factor for cardiac events, including heart attack and stroke. In people with high cholesterol, garlic has been shown to reduce both total cholesterol and “bad” LDL, while slightly improving protective ”good” HDL. Researchers say the 8% reduction in total cholesterol seen in studies is associated with a 38% reduced risk of coronary events by age 50.

Around the world, about 25% of adults have high blood pressure, and the condition is linked to seven million deaths each year. In one meta-analysis, garlic supplements were found to be more effective at curbing blood pressure compared to a placebo, especially in people diagnosed with hypertension. Another study found that garlic supplements have the potential to reduce blood pressure in people with hypertension, while simultaneously lowering cholesterol and stimulating the immune system.

Garlic and other vegetables in the allium family, including onions and leeks, have been linked to a reduced risk of several types of cancer, including of the stomach, throat, prostate, and colon. Natural compounds in garlic are known to help selectively kill off cancer cells, and prevent cancer from growing and spreading.

In addition to supporting learning and memory, aged garlic extract may also help prevent cognitive decline by protecting brain neurons. The veg also helps fight against the brain changes known to be a precursor to neurodegenerative conditions, including Alzheimer’s.

Garlic functions as a prebiotic, food for beneficial bacteria in the gut tied to immunity and positive mood. Research has also shown that aged garlic extract positively improves the diversity of microbes in the gut, including an increase in the number of beneficial and immune-stimulating bacteria.

A high consumption of allium vegetables, including garlic, is associated with protection against hip osteoarthritis, the most common disabling joint condition affecting older adults. Scientists believe the plant’s natural compounds help fend off the breakdown of joint cartilage and bone.
