Garlic (formally called Allium sativum) is a member of the Allium family, and is closely related to the onion, leek, chive, and similar vegetables. Garlic and its relatives are distinguished by the bulbs that grow on them.

Garlic has been used for thousands of years for food and as a traditional approach for medicine and healing. Garlic is native to Asia and India, with close to 85 percent of the world’s garlic production coming from China (about 80%) and India (5%).

Garlic plants can grow to over three feet in height. A garlic clove can be planted in the ground to grow into a new bulb, which normally yields about 5-10 new garlic cloves. Garlic plants are relatively easy to plant and cultivate in mild climates, where they can grow year-round.

Garlic is one of the most highly nutritious foods a person can consume. One clove of raw garlic provides a significant amount of the daily recommended values for Vitamin B-6, Vitamin C, Vitamin K, calcium, protein, manganese, selenium, fiber, copper, potassium, phosphorus, iron, and other healthy nutrients.

These sulfur compounds, mostly derivatives of allyl (a chemical structure that gets its name from the word “garlic”) make their way from the intestines during digestion and into the bloodstream, bringing with them many health benefits.

Some of the most productive and useful of the garlic compounds are Allicin and Allyl:

  • Allicin: Allicin in created whenever a garlic clove is crushed or chopped. This compound is garlic’s natural defense against danger from pests. Allicin has been shown to help in fighting colds. Allicin is thought to be the most useful chemical compound that exists in garlic.
  • Diallyl disulphide: This compound is found in the distilled garlic oil. It helps to detoxify cells and prevent inflammation. Diallyl disulphide also inhibits mold and bacteria growth in the cells.
  • S-allyl cysteine: This compound has been found to lower cholesterol levels.
  • Diallyl trisulfide: Diallyl trisulfide has some anti-cancer effects in the prostate and breast. It has also been shown to reduce blood pressure and cholesterol levels.

Garlic’s Use in Promoting General Health and Vitality

In addition to being used as a natural remedy for diseases and sickness, garlic is often used to promote general health, especially by providing energy to cells and to the body, to increase blood flow, and to provide the nutrition required by the body’s systems in their normal operation.

Two specific areas in which garlic has proven to be a legitimate contributor is in athletic performance and aging.

Athletic Performance

Garlic has been shown to increase the ability of athletes to perform at higher levels. This athletic performance benefit comes from the ability of garlic administration to increase the maximum oxygen consumption and endurance performance time of athletes as described in a study of college athletes in Turkey.

Other studies have revealed similar findings, that athletes’ bodies are able to take in more oxygen and therefore perform better when there is garlic in their systems. For this reason, garlic is often referred to as possibly the earliest “performance enhancer.” Understanding its value, the ancient Greeks used garlic to help the original Olympians perform their best.

Aging

In line with the benefits provided by garlic for the body that help with athletic performance and disease prevention and treatment, garlic is also helpful as an anti aging protocol. It is well understood that aging and the diseases and debilitation that accompany the aging process are due to the proliferation of free radicals (unpaired electrons moving through the body that damage cells, protein, and DNA) that are introduced throughout the body as time passes.

Garlic Antioxidants Help with Aging, Fight Free Radicals

Garlic contains antioxidants that reduce the free radical population and thereby slow the effects of aging. There is evidence that garlic supplements can help with preventing Alzheimer’s Disease and dementia.

Garlic and the Mediterranean Diet

If you’ve ever heard of the Mediterranean diet, you might know that following that diet has been correlated with being healthier. Studies done in the mid- to late-1900s showed that people in countries bordering the Mediterranean Sea, especially Italy and Greece, were much healthier than Americans. The health difference was traced to what has since been popularly referenced as the Mediterranean diet.

Garlic is one of the significant components of the Mediterranean diet. Garlic is used in the majority of meals that comprise the Mediterranean diet along with fresh vegetables, fruits, nuts, whole grains, yogurt, olive oil, fish, seafood, and other herbs and spices. Many consider garlic to be the most critical element of the diet.

How to Use and Consume Garlic

It’s one thing to know and understand that garlic can provide lots of health benefits. It’s another to figure out how to get all that goodness into your body, especially without having to chomp down garlic cloves and without dealing with garlic breath all day, every day.

There are several different ways to consume garlic, including everything from eating raw garlic cloves to drinking garlic oil to taking garlic supplements, which are sometimes combined with other nutritious elements for specific health purposes.

Raw Garlic

Eating Garlic Cloves

Some people find it not too far a stretch to simply peel out garlic cloves and chomp them down. Eating garlic cloves is obviously the most basic way to consume garlic, and it’s not an option for most people.

Minced Garlic

Chopped or minced garlic is a much more popular mechanism for consuming garlic. Minced garlic is typically found in homemade salsa as well as in guacamole recipes and on toast with butter. Less frequently, minced garlic is added to salad dressings and added to mashed potatoes.

Garlic Powder

Most people’s spice racks have garlic powder in them. I use garlic powder all the time in my cooking habits, including in stir fries, when seasoning beef or chicken and in most recipes that aren’t intended to be strictly sweet.

Garlic powder is made by drying out garlic cloves and then grinding them into fine particles.

Raw Garlic Juice

Raw garlic cloves are often turned into juice using a garlic press or blender. This form of garlic intake is more convenient for your body to absorb the compounds that make garlic so useful.

Cooked Garlic

Garlic is a popular ingredient in many cooked dishes, including in forms that include chopped garlic, minced garlic, and garlic powder. Garlic can be cooked into lots of different dishes to create a unique flavor. When garlic is cooked, its flavor turns from being pungent to one that is much sweeter and mellow.

Garlic Oil

Garlic oil is most often actually garlic-infused olive oil. Sometimes other types of oils are used, but olive oil is by far the most popular. Often, salt or some other seasoning is used to change the flavor of the oil.

Garlic Supplements

Thousands of different garlic supplements are available for those who want to be deliberate about their intake of garlic without what is often seen as an inconvenience with integrating garlic in some of its other forms into their daily diets.

Supplement companies have developed lots of different processes for creating variations of garlic intended to highlight particular benefits of the chemical compounds found in garlic.

Health Studies Involving Garlic

For those who want to consume all the scientific nitty gritty about garlic, there are hundreds of studies published on PubMed and other academic and scientific study databases. Here are some that I found most compelling regarding what garlic does for improved health and to fight disease.

I hope that you’ve been able to see how beneficial it is for you to include garlic into your diet in whichever way it fits with your lifestyle and preferences. Making small adjustments to what you eat to include garlic, or purchasing supplements that provide you with those benefits will improve your health and likely extend and improve your overall life experience.
