Health Benefits of Raw and Cooked Garlic

Garlic is used in cooking for both its flavor and diverse range of health benefits. We'll look at some health benefits of raw garlic, and make some suggestions for recipe ideas.

Garlic is a bulbous flowering plant in the onion (Allium) family. It is a common ingredient in many dishes, and is often used as a base for many recipes. Garlic is commonly cooked by being sautéed, roasted, or baked in the oven. Roasted garlic tastes great as a hearty snack, in a spread, or as a vegan pizza topping for some extra heat.

Though much less common, garlic can also be consumed raw. Raw garlic has a much stronger flavor than cooked garlic, but it can be consumed safely. It is often added to sauces such as pesto and aioli, as well as other condiments or dressings. Recipe ideas for raw garlic include homemade pesto, or making garlic and ginger tea. Garlic has been used in cooking for centuries, and was commonly used a medical treatment in ancient cultures.

1. Boosts Immune System

Garlic offers an immune system boost to help prevent colds and flus. Whole garlic is especially good at fighting colds as it contains a compound called alliin. When garlic cloves are crushed or chewed, this compound turns into allicin, which is the main active ingredient in garlic. This active ingredient has been found to boost the disease fighting response of some types of white blood cells in the body when they encounter viruses. Garlic also has antimicrobial and antibiotic properties, which means it could help your body fight off the growth of viruses and bacteria to prevent colds and flu.

2. May Reduce Cancer Risk

Another health benefit of garlic is that it has potential anticancer properties. Garlic is a good source of phytochemicals, which provide the body with protection from cell damage, and this may reduce your risk of getting certain cancers. Research shows that eating garlic as a way to consume phytochemicals can have anti-carcinogenic effects and can lower the risk for stomach and colorectal cancers in particular. Garlic is also packed full of antioxidants, which soak up the damaging free radicals in the body that can lead to diseases like cancer.

3. May Improve Heart Health

Garlic is also thought to improve heart health. A 2019 study has found that garlic can lower blood pressure and decrease arterial stiffness for people with a condition called hypertension, if two capsules of garlic extract are consumed everyday day for two months. Another study shows the positive effects that garlic has on heart health, including preventing cell damage and lowering blood pressure. 

4. Might Reduce Inflammation

According to a 2020 study published in Phytotherapy Research, garlic is also known to reduce inflammation in the body. In a study of 70 women with the inflammatory autoimmune disease rheumatoid arthritis, the group of women who took 1,000 milligrams of garlic supplements per day for eight weeks had lower inflammation, less pain and fatigue, and fewer tender joints compared with the placebo group. Chronic inflammation in the body is linked to various chronic health conditions such as cancer, diabetes, and heart disease. 

5. Reduce Blood Clotting

Garlic could also protect your arteries too, with studies showing that consumption of one clove of garlic a day could be beneficial in preventing thrombosis, a serious health condition associated with blood clotting.

Garlic is also known to promote healthy brain function. A 2020 study has found that an aged extract of garlic may be effective at reducing the risk of developing Alzheimer’s disease. A study referenced therein has found that garlic can protect against cognitive and learning memory deficits. The study also showed how garlic’s antioxidant, anti-inflammatory, and modulatory properties can positively affect neurotransmitter function in the brain regions that are associated with the development of Alzheimer’s disease. 

10. Clears Up Acne

Garlic can also help to clear up skin conditions such as acne by killing acne causing bacteria. The antibacterial, antifungal, antiviral, and antiseptic properties from allicin can help to clear up acne, as well as reduce swelling and inflammation of the skin. A 2011 study shows that garlic can also be an effective treatment for various other skin conditions including aging, fungal infections, as well as for wound healing.

• Manganese: 0.75mg (2% of the RDA) Manganese is essential for bone health and development.

12. Improves Digestion

Garlic is also beneficial for improving digestive function. According to a 2013 study published in the Food Science & Human Wellness Journal, one of the major components in garlic, fructan, is known to act as a prebiotic in the gut. This means that it helps to promote the production of ‘good’ gut bacteria and overall aids digestive health. 

Drawbacks of Garlic

For most people, the most prominent drawback of eating garlic is the strong and distinctive odor that lingers on your body, and in your mouth – otherwise known as garlic breath.
