Food Facts (10)
Every month a new interesting food fact will be listed for your health and convenience. There will be nutriental information, facts and health benefits about each special food. This issue we have Garlic.
Garlic
Garlic has been used as both food and medicine in many cultures for thousands of years, dating back to when the Egyptian pyramids were built. In early 18th -century France, gravediggers drank a concoction of crushed garlic in wine they believed would protect them from the plague that killed many people in Europe. More recently, during both World Wars I and II, soldiers were given garlic to prevent gangrene. Today garlic is used to help prevent heart disease, including atherosclerosis (plaque buildup in the arteries that can block the flow of blood and possibly lead to heart attack or stroke), high cholesterol, high blood pressure, and to improve the immune system. Garlic may also protect against cancer.
While the science is not conclusive, research shows promise for garlic in the areas of cancer protection and heart-related risk factors for patients.
Garlic is rich in antioxidants, which help destroy free radicals -- particles that can damage cell membranes, interact with genetic material, and possibly contribute to the aging process as well as the development of a number of conditions, including heart disease and cancer. Free radicals occur naturally in the body, but environmental toxins (including ultraviolet light, radiation, cigarette smoke, and air pollution) can also increase the number of these damaging particles. Antioxidants neutralize free radicals and may reduce or even help prevent some of the damage they cause over time.

Cardiovascular disease
Studies report that garlic consumption may decrease the progression of cardiovascular disease. Cardiovascular disease is associated with several factors, including raised serum total cholesterol, raised low density lipoprotein (LDL), and increased LDL oxidation (free radical damage), increased platelet aggregation (clumping), hypertension, and smoking. Garlic may help decrease LDL and total cholesterol levels while raising good cholesterols (high density lipoprotein, or HDL), decreasing platelet aggregation (helps the blood flow more easily), and decreasing blood pressure. Recently, garlic was also found to decrease two other markers of cardiovascular disease, homocysteine and C-reactive protein.
Garlic may also reduce blood pressure. Numerous studies have reported that oral garlic is associated with reduced systolic and diastolic blood pressure.
Common cold
A well-designed study of nearly 150 people found that garlic helps prevent and treat the common cold. In this study, people received either garlic supplements or placebo for 12 weeks during "cold season" (between the months of November and February). Those who received garlic had significantly fewer colds than those who received placebo. Plus, when faced with a cold, the symptoms dissipated more quickly among those receiving garlic compared to those receiving placebo.
Cancer
Garlic may strengthen the immune system, helping the body fight diseases such as cancer. Laboratory studies suggest that garlic may have anti-cancer activity. Studies that follow groups of people over time suggest that people who have more raw or cooked garlic in their diet are less likely to develop certain types of cancer, particularly colon and stomach cancers. In fact, a review of 7 studies researchers found a 30% reduction in risk of colorectal cancer among people who had a high intake of raw or cooked garlic. Dietary garlic may also protect against the development of breast, prostate, and laryngeal (throat) cancers.
• A large-scale study, called the Iowa Women's Health Study, looked at the garlic, fruit, and vegetable consumption in 41,000 middle-aged women. Results showed that women who regularly consumed garlic, fruits, and vegetables had a 35% lower risk of developing colon cancer.
• Garlic may help the immune system function more effectively during times of need such as in cancer. In a study of 50 patients with inoperable colorectal, liver, or pancreatic cancer, immune activity improved after they were given aged garlic extract for 6 months.
• Studies also suggest that aged garlic supplementation may reduce the side effects of chemotherapy, including fatigue and anorexia (lack of appetite). Further, results found that aged garlic decreased heart and intestinal damage commonly seen with certain chemotherapy agents.
While these results are promising, more research is needed to better understand whether dietary intake of garlic and other plants in the same family (such as onions, leeks, scallions, chives, and shallots) truly help protect against cancer.
Other uses
• Laboratory studies suggest that large quantities of fresh, raw garlic may have antiparasitic properties against the roundworm, Ascaris lumbricoides, which is the most common type of intestinal parasite. Garlic for this purpose, however, has not been tested in people.
• Fresh garlic contains allicin, which is reported to have antibacterial, antiviral, and antifungal properties. Some studies have reported that garlic consumption may kill bacteria known to cause ulcers, but there are also studies that report no effect on this bacteria. Several studies report that topical application of garlic may help treat fungal skin conditions, such as Tinea cruris and Tinea corporis.
• Preliminary studies show that garlic may help combat fatigue. More research is needed.
