6 Health Benefits of Garlic

healthbenefitsofgarlic

You likely know garlic well, as it is a popular ingredient in almost every culture’s cuisine around the world. Considered a potent sulfurous vegetable (yes, it’s considered a vegetable—it’s part of the onion family), garlic can be imbibed in a variety of ways from raw to fermented and sautéed to capsuled as dietary supplements.

Garlic’s nutritional qualities make it a highly medicinal food that has positive effects on overall health. The health benefits of garlic are confirmed by research, which shows it as an integral ingredient to fight degenerative disease, build a strong and healthy defense system, and so much more.

Learn some of the most powerful ways that garlic can help to improve and support your health, while also enhancing the flavors of your food.

1. Boosts Immune System

From nibbling on a piece of raw garlic to taking dietary supplements of an organosulfur obtained from garlic, garlic has been shown to have supportive immune-boosting properties. Garlic is a triple-threat—antimicrobial, antifungal, and antibacterial.

Garlic is also known for its high antioxidant levels, especially rich in four main chemical classes: alliin, allyl cysteine, allyl disulfide, and allicin. These antioxidant levels help protect your cells keeping you healthy and strong.

Although you have likely heard that garlic aids in the prevention of the common cold, studies showing its benefits against cold and flu viruses remain limited.

One study in 2011, however, examined a group of 146 participants receiving either a garlic supplement (allicin) or a placebo daily over 12 weeks. The participants were assessed for various cold and flu symptoms. The results showed a resounding benefit with taking garlic for immunity. The frequency, duration, and intensity of cold symptoms were each positively impacted by a regular dose of garlic.

2. Lowers Blood Pressure

Known as hypertension, chronically elevated blood pressure, aka high blood pressure, is a common condition. According to the CDC (Centers for Disease Control and Prevention), nearly one in every three adults in the U.S. are affected by high blood pressure.

One popular remedy, tracing back to ancient texts as far as 1500 BC, is consuming garlic. Garlic is known to support healthy blood pressure through stimulating nitic oxide, causing a vasodilating response in the circulatory system.

One study based on a meta-analysis looked at 20 trials with a total of 970 participants. When participants were using garlic, there was a mean decrease in both systolic and diastolic blood pressure compared with the placebo.

There is consistent evidence that garlic is a reliable and effective method in treating hypertension. Garlic is a safe and tolerable alternative or complementary treatment to include in any high blood pressure protocol.

3. Helps Prevent Cancer

The strong aroma of garlic cooking on the stovetop goes beyond its delicious scent. The sulfur compounds that give garlic its robust flavor and smell are the same components that provide many cancer-fighting properties. Many of the phytonutrients found in a clove of garlic have been associated with cancer prevention.

Eating more garlic has been shown to enhance cancer-fighting properties in a variety of cancers.

One study looked at a group of 345 participants diagnosed with primary breast carcinoma. According to the study, breast cancer risk decreased with increased consumption of garlic (combined with onion and cereal fiber).

A 2018 study examined the molecular and cellular activity of various cancer cells with garlic extract. The results showed inhibited growth of these various cancer cells in vitro and vivo (in a test tube and a living organism). The potency of the garlic extract was also shown to diminish with heat and processing suggesting that garlic is somewhat volatile.

Garlic is a promising ingredient to include in your diet for cancer prevention and inhibition.

4. Detoxifies and Supports Liver

Detoxication is a natural function of the human body when it is in a healthy state. Your liver is considered the primary detoxification organ. Ensuring you are detoxifying efficiently simply leads to greater wellness and health.

There are two primary phases of liver detoxification:

  • In phase one, the liver supports the first line of defense against toxicity. In this phase, the liver breaks down toxins through oxidation.
  • In phase two, the liver toxins that have been altered in phase one can now be conjugated (or linked to a molecule that will allow its excretion). This process is reliant on adequate nutrients, phytonutrients, antioxidants, and protein.

Research shows that garlic contains some of the specific amino acids and antioxidants that may be helpful in the phase two detoxification process, making garlic a great addition to your diet for optimal detoxification and cleansing.

5. Includes Anti-inflammatory Properties

Inflammation is a condition associated with almost every disease in the body. While inflammation can be acute or chronic, the treatment or management of inflammation in the body is imperative for health and vitality.

According to Harvard Medical School, food can be inflammatory or anti-inflammatory. Processed foods high in sugar, additives, preservatives, and artificial ingredients lead to more inflammation, while whole foods—low in sugars and high in antioxidants and phytonutrients—are more anti-inflammatory.

Garlic is one of these anti-inflammatory foods. One study looked at the inflammation response with regards to arthritis. The results showed a clear decrease in inflammation and arthritis symptoms. With high levels of sulfur compounds, specifically thiacremonone, garlic helps regulate the inflammatory response in the cells.

Garlic could be a useful addition to any anti-inflammatory regimen.

6. Helps Prevent Alzheimer’s Disease

Alzheimer’s disease is a form of dementia that acts on various functions of the brain and everyday living. Memory, cognitive function, and mental clarity are some of the aspects of brain function that are directly and negatively impacted by Alzheimer’s disease.

Garlic has been shown to contain some of the necessary antioxidants and phytonutrients that protect the brain from the specific type of oxidative stress that can lead to worsening symptoms of Alzheimer’s disease.

While garlic is roasting, melt butter in a large pot and add sliced onions. Sauté over medium heat, stirring constantly until onions are translucent. Add the herbs, salt, and pepper and sauté for 2 minutes.

Let garlic cloves cool slightly, then carefully pick up the shell of the garlic heads. Add peeled garlic cloves to the onion mixture in the pot.
