15 Health Benefits of Garlic

Garlic as super food

Garlic isn’t just a staple ingredient for your culinary delights; it’s a super food with a centuries-old reputation for its healing properties. With this blog, we’ll peel back the layers to reveal the powerful benefits of garlic to your health. From combating high cholesterol to boosting male health, garlic’s therapeutic capabilities are vast and well-documented.

Prepare to be amazed as we explore fifteen compelling reasons to increase your garlic intake and enhance your overall wellbeing.

1. Battles Bacteria and Viruses

Garlic has been celebrated for its antibacterial and antiviral properties. Allicin, the main active compound in garlic, is often responsible for these health benefits. Adding garlic to your diet might make you say goodbye to colds and infections more quickly.

2. Lowers High Blood Pressure

Studies have shown that garlic supplements can have a significant impact on reducing blood pressure in people with hypertension. This is excellent news if you want to maintain a healthy cardiovascular system naturally.

Garlic’s ability to lower blood pressure is primarily attributed to its rich content of organosulfur compounds, notably allicin, which can help relax blood vessels. When blood vessels relax, the blood flows more freely, reducing the pressure on the arterial walls. This process is similar to how some blood pressure medications work, making garlic a natural adjunct to traditional treatments. Regular consumption of garlic, especially in its raw form or as a supplement, can lead to significant improvements in blood pressure levels, particularly in individuals with known hypertension.

3. Reduces Cholesterol Levels

High cholesterol can lead to heart disease, but the good news is that the consumption of garlic has been linked to lower LDL (bad) cholesterol levels. More than just adding flavour to your food, garlic might help keep your arteries clear. The allicin in garlic has been found to inhibit enzymes that produce cholesterol, reducing LDL cholesterol levels.
Continuing the discussion on garlic’s ability to reduce cholesterol levels, it’s crucial to understand the extent of its impact.

Research indicates that garlic can lower LDL cholesterol by 10-15%. This effect is primarily due to garlic’s allicin content, which inhibits the enzymes responsible for cholesterol production and enhances the elimination of LDL cholesterol from the body.

Furthermore, garlic promotes the health of the arteries by preventing the oxidation of LDL cholesterol, a process that contributes to plaque formation and cardiovascular disease. Incorporating garlic into your diet through fresh cloves or dietary supplements can effectively manage cholesterol levels and support heart health.

4. Packed with Antioxidants

Garlic contains antioxidants that support the body’s protective mechanisms against oxidative damage. These antioxidants can lower the risk of Alzheimer’s disease and dementia, making garlic a brain-friendly food.

The prominent antioxidants found in garlic include allicin, alliin (a sulfoxide that is a natural constituent of fresh garlic), and selenium, each playing a pivotal role in combating oxidative stress in the body. Allicin, released when garlic is chopped or crushed, not only lends garlic its distinct aroma but also acts as a potent antioxidant. T

his compound helps neutralize free radicals in the body, thereby reducing oxidative stress, which can lead to premature ageing and an array of chronic diseases, including heart disease and cancer. Selenium, another antioxidant in garlic, supports the immune system and is crucial in maintaining thyroid function. Together, these antioxidants contribute to the protective effects of garlic against cellular damage, enhancing overall health and longevity.

5. Improves Bone Health

Research indicates that garlic can minimize bone loss by increasing estrogen levels in females, suggesting a role for garlic in maintaining bone health. Whether it’s osteoporosis you’re worried about or general bone upkeep, garlic is your friend.

Garlic’s benefits for bone health do not end with estrogen levels in women. It also holds promising implications for men, especially concerning the modulation of sex hormones that can influence bone density. Garlic supplementation may support healthier bones by impacting the overall balance of hormones and promoting the production of osteoblastic (bone-forming) cells.

In men, this could reduce the risk of osteoporosis and enhance bone strength. While more research is needed to fully understand garlic’s impact on male bone health, its rich nutritional profile—including vitamins and minerals essential for bone maintenance—suggests it can be valuable to anyone’s diet for improving and preserving bone health.

6. Supports Immune Function

Consuming garlic regularly can help fortify your immune system. It’s primarily known for its positive effects on improving immunological responses, allowing your body to fight those pesky illnesses more effectively.

Garlic’s impact on immune health extends beyond its general reputation as a disease-fighter. It specifically enhances the functioning of immune cells, like macrophages, lymphocytes, and natural killer cells, which are crucial for the body’s defence against pathogens. The sulfur-containing compounds in garlic, particularly allicin, play a pivotal role in this enhanced immune response.

These compounds are believed to stimulate these immune cells, bolstering their efficacy in combating infections and illnesses. Furthermore, garlic’s ability to improve antioxidant status reduces inflammation and oxidative stress, supporting a more robust immune system. This dual action of direct stimulation of immune cells and reduction in inflammatory and oxidative stress markers makes garlic a formidable ally in maintaining good health and preventing various diseases.

7. Potent Anti-Inflammatory

Garlic exhibits anti-inflammatory properties, which can be beneficial in managing inflammation-related conditions. For those suffering from arthritis or other inflammatory diseases, garlic may provide some relief.

The anti-inflammatory effects of garlic are attributed to its high sulphur content, which is responsible for most of its therapeutic attributes, including its ability to reduce inflammation. Among the sulphur-containing compounds, di allyl di sulfide (DADS) plays a significant role in inhibiting the pathways that lead to inflammation. By modulating specific inflammatory markers in the body, garlic can effectively decrease the severity of inflammation, particularly in conditions such as arthritis.

The benefits of garlic in inflammation extend to improved joint health and reduced pain and swelling for individuals suffering from chronic inflammatory conditions. Regular consumption of garlic, either in raw form, as an extract, or through supplements, has been correlated with a decrease in symptoms associated with inflammatory diseases, offering a natural and accessible means of managing pain and enhancing the quality of life.

As researchers continue to unravel the complexities of garlic’s anti-inflammatory properties, it stands as a promising adjunct therapy for those seeking to mitigate inflammation through dietary means.

8. Aids in Detoxification

Heavy metal toxicity can cause severe damage to major organs, but garlic has been shown to reduce these toxic effects. Its sulphur compounds have been proven to protect organ damage from heavy metal toxicity.

In studies involving industrial workers exposed to heavy metals, garlic supplementation significantly reduced levels of these toxic substances in the blood. Specifically, garlic has been demonstrated to enhance the body’s mechanisms for detoxification, helping to expel harmful metals like lead and cadmium.

The sulphur compounds in garlic, which include alliin and allicin, are believed to play a crucial role in this process. They help to activate liver enzymes responsible for expelling toxins from the body, providing a natural method to cleanse and protect the body from the detrimental effects of heavy metal accumulation. This detoxifying effect not only safeguards the organs from potential damage but also contributes to overall health and wellbeing by preventing the long-term adverse effects of heavy metal toxicity.

9. Enhances Athletic Performance

Ancient civilizations used garlic to reduce fatigue and enhance the work capacity of labourers. It may be helpful for athletes looking to sustain their performance and reduce exercise-induced fatigue.

10. May Lower the Risk of Heart Disease

By reducing factors like high blood pressure and cholesterol, garlic directly contributes to the wellbeing of your heart. It also helps produce hydrogen sulphide, which relaxes blood vessels and improves blood flow.

Garlic’s influence on heart health is profound and multidimensional. It lowers the levels of bad cholesterol (LDL) and significantly impacts reducing blood pressure, a significant risk factor for heart disease. The active compounds in garlic, particularly allicin, are thought to be responsible for these beneficial effects. They work by stimulating the production of nitric oxide in the blood vessels, which helps in the relaxation and dilation of these vessels, thereby improving blood flow and reducing blood pressure.

Additionally, garlic’s antioxidant properties are crucial in preventing oxidative damage to the heart and blood vessels, further fortifying the cardiovascular system against diseases. Regularly including garlic in the diet may serve as a simple yet powerful dietary strategy to protect against heart disease, highlighting its importance for culinary purposes and its therapeutic benefits in cardiovascular health maintenance.

11. Mitigates Hair Loss (Alopecia)

Garlic gel applied to the scalp has shown effectiveness in treating alopecia areata. If hair loss is a concern, consider speaking with a healthcare provider about whether a garlic-based treatment might suit you.

The application process is straight forward for those considering garlic for hair loss treatment, yet it requires consistency for the best results. Initially, one can opt for garlic-infused oil or a commercially available garlic gel specifically designed for hair application.

To use garlic-infused oil, crush a few cloves and mix them with a carrier oil such as coconut or olive oil. Let this mixture sit for a few days to allow the garlic’s beneficial properties to infuse into the oil.

Before applying to the scalp, perform a patch test to ensure no allergic reaction. Gently massage the garlic oil or gel into the scalp, focusing on areas with noticeable hair thinning. Leave it on for about 30 minutes or overnight, if comfortable, before washing it out with a mild shampoo. It’s recommended to repeat this treatment at least two to three times a week for visible improvements. Consistency and patience are essential, as natural remedies may take time to show results.

12. Helps with Weight Control

Garlic could assist in weight control thanks to its potential to regulate the formation of fat cells in our bodies. Including garlic in a balanced diet may prevent weight gain and promote healthier weight management.

Research suggests that garlic may impact weight control through its ability to inhibit the pre-adipocyte differentiation process, essentially preventing pre-fat cells from converting into fat cells. A study published in the Journal of Nutrition highlighted garlic’s role in fat reduction. This study demonstrated that mice fed a high-fat diet and a garlic supplement had reduced body weight and fat mass compared to those who did not receive garlic. Additionally, garlic’s ability to improve thermogenesis, which is the body’s burning of calories to produce heat, has also been proposed as a mechanism for weight-control benefits.

These findings suggest that incorporating garlic into one’s diet could be an effective strategy for managing weight, alongside regular exercise and a healthy diet. However, it’s important to note that garlic should complement these lifestyle practices rather than replace them. For individuals looking to maintain or achieve a healthy weight, turning to garlic as a natural supplement might provide an added advantage, contributing to the overall effectiveness of weight management strategies.

13. Boosts Digestive Health

The benefits of garlic extend to the digestive system as it helps to prevent and reduce various digestive ailments. From helping combat diarrhoea to promoting healthy gut flora, garlic is an excellent addition to your gut health regimen.

Garlic’s effectiveness in boosting digestive health can be maximized by incorporating it into your daily diet in various forms, such as raw, cooked, or as a supplement. To enhance digestive health, eating a clove of raw garlic with water on an empty stomach can kick-start the digestive process, aiding in reducing inflammation and promoting healthy gut flora. Alternatively, adding garlic to cooked dishes can also provide digestive benefits without the intense flavour of raw garlic.
