For thousands of years, garlic has been used in many cultures because of its potent flavor and numerous health benefits. The prominent use of garlic was documented by several major civilizations, such as the Greeks, Romans, Chinese, and Egyptians . Modern science is now confirming these beneficial health effects.
What is Garlic?
Garlic is primarily used as a spice, but botanically speaking, garlic (Allium sativum) is considered a vegetable. Garlic belongs to the onion family, along with leeks, chives, and shallots .
Garlic is typically consumed in smaller amounts due to its strong taste. You can cook garlic crushed, whole, or peeled. Most commonly, garlic is boiled, sauteed, or roasted.
You can use garlic on your keto diet in sauces and dishes like pasta, stir-fries, and baked vegetables. Try some of these delicious dishes featuring garlic:
Here are five reasons to eat garlic for your health:
1. Contains Medicinal Compounds
Scientists now associate most of the health benefits with the sulfur compounds formed when you chop, crush, or chew a garlic clove. Some of these advantageous compounds include s-allyl cysteine and diallyl disulfide. The sulfur compounds go from your digestive tract to the rest of your body, where they exert potent biological effects .
2. Might Boost Immune Function
Garlic supplements might boost the function of your immune system according to some research. For example, in one large 12-week study, a daily garlic supplement reduced the number of colds by 63% compared to a placebo .
Some studies show that in high doses, the sulfur compounds present in garlic can protect against organ damage caused by heavy metal toxicity. Heavy metal toxicity like high lead levels in the body can lead to headaches, high blood pressure, and other symptoms .
3. High in Nutrition and Low in Calories
Garlic gives you plenty of bang for your buck in the way of nutrition. One clove of raw garlic contains nutrients like vitamin C, B6, selenium, and manganese. Garlic also has fiber and hardly any carbs! 
4. Good Source of Antioxidants
Garlic provides antioxidants that support your body’s protective mechanisms against oxidative damage. According to promising research, high doses of garlic supplements might increase humans’ antioxidant enzymes and reduce oxidative stress in those with high blood pressure .
High blood pressure (hypertension) is an important driver of cardiovascular disease. Impressive human studies on those with high blood pressure reveal how garlic supplements can significantly reduce blood pressure. The supplement doses must be fairly high to achieve the desired effects. The amount needed is about the same as four garlic cloves per day .
