Proven Health Benefits of Garlic
Do you know that there are proven health benefits of garlic and that you should take advantage of them? I am sure you’ve heard about them. But if you haven’t, I will give you some of them here in this blog post.
Garlic is a plant in the allium onion family.
It is closely related to onions, shallots, and leeks. Each segment of a garlic bulb is called a clove. There are about 10 to 20 cloves in a single bulb, give or take.
Garlic grows in many parts of the world and is a popular ingredient in cooking due to its strong smell and delicious taste.
However, throughout ancient history, the main use of garlic was for its health and medicinal properties.
Scientists now know that most of its health benefits are caused by sulfur compounds formed when a garlic clove is chopped, crushed or chewed.
Perhaps the most famous of those is known as allicin. However, allicin is an unstable compound that is only briefly present in fresh garlic after it’s been cut or crushed
Other compounds that may play a role in garlic’s health benefits include diallyl disulfide and s-allyl cysteine
A 1-ounce (28-gram) serving of garlic contains
- Manganese: 23% of the RDA
- Vitamin B6: 17% of the RDA
- Vitamin C: 15% of the RDA
- Selenium: 6% of the RDA
- Fiber: 0.6 grams
- Decent amounts of calcium, copper, potassium, phosphorus, iron and vitamin B1
Garlic also contains trace amounts of various other nutrients. In fact, it contains a little bit of almost everything you need.
This comes with 42 calories, 1.8 grams of protein and 9 grams of carbs.
Garlic supplements are known to boost the function of the immune system.
One large, 12-week study found that a daily garlic supplement reduced the number of colds by 63% compared to a placebo (6).
The average length of cold symptoms was also reduced by 70%, from 5 days in the placebo group to just 1.5 days in the garlic group.
Another study found that a high dose of aged garlic extract (2.56 grams per day) reduced the number of days sick with cold or flu by 61%.
Cardiovascular diseases like heart attacks and strokes are the world’s biggest killers.
High blood pressure, or hypertension, is one of the most important drivers of these diseases.
Human studies have found garlic supplements to have a significant impact on reducing blood pressure in people with high blood pressure.
In one study, 600–1,500 mg of aged garlic extract was just as effective as the drug Atenolol at reducing blood pressure over a 24-week period.
Garlic can lower total and LDL cholesterol.
For those with high cholesterol, garlic supplements appear to reduce total and/or LDL cholesterol by about 10–15%.
Looking at LDL (the “bad”) and HDL (the “good”) cholesterol specifically, garlic appears to lower LDL but has no reliable effect on HD.
Garlic was one of the earliest “performance enhancing” substances.
It was traditionally used in ancient cultures to reduce fatigue and enhance the work capacity of laborers.
Most notably, it was given to Olympic athletes in ancient Greece.
Rodent studies have shown that garlic helps with exercise performance, but very few human studies have been done.
People with heart disease who took garlic oil for 6 weeks had a 12% reduction in peak heart rate and better exercise capacity.
However, a study on nine competitive cyclists found no performance benefits.
