For thousands of years, people throughout the world have turned to garlic for its many medicinal and culinary properties. In modern naturopathy, practitioners widely recommend garlic for its purported ability to prevent and treat medical conditions. Limited scientific investigations have supported, but not conclusively proven, many of the health benefits traditionally attributed to this pungent rhizome. Garlic is generally regarded as safe when it is consumed as part of a balanced diet. However, it is best to consult your primary health care provider before eating large amounts of garlic on an ongoing basis.
Cardiovascular Health
The American Heart Association, or AHA, acknowledges garlic's potential as a treatment or preventative remedy for several conditions affecting the heart. According to the AHA, "promising, modest, short-term" trials demonstrate that garlic can reduce cholesterol levels, prevent blood clots and decrease blood pressure. As a result, garlic may help prevent serious cardiovascular episodes such as heart attack and stroke. However, the AHA notes that findings are inconsistent; garlic's benefits may vary depending on the type of garlic, its potency and its preparation.
Antioxidant Protection
The University of Maryland Medical Center, or UMMC, regards garlic as a potent antioxidant. Antioxidants help defend healthy cells against the damages associated with free radicals, which are highly reactive molecules associated with aging, heart disease, cancer and sudden death. According to the UMMC, garlic may help neutralize free radicals produced by sunlight, environmental toxins, cigarette smoke and radiation. By eating garlic every day, you can minimize cellular damage associated with these compounds.
Cancer Prevention
Because of its powerful antioxidant protection, garlic may help defend against several types of cancer. According to the UMMC, people who eat garlic every day appear to be less likely to develop cancers of the breast, colon, stomach, prostate or throat. The UMMC also suggests that garlic may help reduce the side effects of chemotherapy, particularly appetite loss. Although UMMC regards these findings as "promising," the organization notes that there is insufficient evidence to conclusively demonstrate garlic's cancer-preventing properties.
Immune Support
As part of a healthy diet, garlic may help support immune function. The National Institutes of Health reports that garlic may defend against meningitis, upper-respiratory infections and fungal infections. The NIH also regards garlic as a theoretical treatment for HIV, urinary tract infections, ear infections and pneumonia. Naturopathic practitioners widely regard garlic as a safe, holistic alternative to conventional antibiotics, but there is not enough evidence to prove its effectiveness for this. Consider eating larger amounts of garlic to boost your immune response during times of stress or illness.
