Garlic: Does It Prevent Cancer and Lower Cholesterol

Am Fam Physician. 2005 Jul 1 72:103-106.

Garlic has long been used medicinally, most recently for its cardiovascular, antineoplastic, and antimicrobial properties. Sulfur compounds, including allicin, appear to be the active components in the root bulb of the garlic plant. Studies show significant but modest lipid-lowering effects and antiplatelet activity. Significant blood pressure reduction is not consistently noted. There is some evidence for antineoplastic activity and insufficient evidence for clinical antimicrobial activity. Side effects generally are mild and uncommon. Garlic appears to have no effect on drug metabolism, but patients taking anticoagulants should be cautious. It seems prudent to stop taking high dosages of garlic seven to 10 days before surgery because garlic can prolong bleeding time.

Garlic has been used for thousands of years for medicinal purposes. Sanskrit records show its medicinal used about 5,000 years ago, and it has been used for at least 3,000 years in Chinese medicine. The Egyptians, Babylonians, Greeks, and Romans used garlic for healing purposes.1 In 1858, Pasteur noted garlics antibacterial activity, and it was used as an antiseptic to prevent gangrene during World War I and World War II.2

The Biting Fighting Garlic

A 2016 review of studies on garlic determined that garlic has the potential to reduce total cholesterol up to 30 milligrams per deciliter .

Try simmering whole cloves of garlic in olive oil until theyre soft, and use them as a spread on foods you find bland. Garlic tastes better than butter, and its a whole lot healthier particularly for lowering cholesterol.

Journal of Nutrition found that regular intake of shiitake mushrooms in rodents appears to have cholesterol-lowering affects. This confirms earlier studies with similar results.

Although shiitake mushrooms have been the subject of much of the research, many other varieties available in the supermarket or at your local farmers market are also thought to be helpful for lowering cholesterol.

Salsa Pico De Gallo And More

Garlic Doesn’t Help High Cholesterol

Garlic doesnt do much for the breath and it stinks for lowering cholesterol. Thats the conclusion of the most rigorous, head-to-head study of raw garlic and popular garlic supplements, despite promoters claims to the contrary.

Whether it was eaten raw in heart-healthy sandwiches, or in pills made of powdered or aged garlic, the strong-smelling herb had no effect on cholesterol in people whose levels were already elevated, the government-funded study found.

If garlic was going to have a chance to work, it would have worked in this study, said researcher Christopher Gardner. But it didnt.

Garlic is a longtime folk remedy for a variety of ills, including heart disease, cancer, infections and even mosquito bites. Scientific research on its purported benefits has had conflicting results. Some previous studies suggested garlic might help lower risks for digestive and prostate cancers, or might reduce blood pressure and cholesterol levels others found no benefit.

Health benefits have been thought to come from a sulfur-containing substance called allicin that is released when raw garlic is chopped or crushed. In lab tests, it can be applied directly to cells and has been shown to prevent cholesterol production.

But any direct benefits to the body from allicin may be diluted when garlic is eaten, said Gardner, an assistant professor of medicine at Stanford University.

The study appears in Mondays Archives of Internal Medicine.

Can Bring Down Total Cholesterol Ldl Cholesterol And Triglyceride Levels

  • Aged garlic extract supplementation was seen to help bring down total cholesterol by as much as 7 percent in one study. When men with hypercholesterolemia took this extract, their low-density lipoprotein cholesterol came down by 10 percent.2
  • Another study revealed that taking garlic in the form of 2 daily doses of garlic powder tablets for 6 weeks helped bring down total cholesterol by 12 percent and LDL cholesterol by 17 percent in subjects with a cholesterol problem. Triglyceride levels also reduced by 6 percent.3
  • Taking half a clove or a clove of garlic, or the equivalent of this in other forms, has been seen to bring down total cholesterol levels by as much as 9 percent in people whose cholesterol levels were greater than 5.17 mmol/L in another study.4
  • An animal study found that giving test subjects raw aqueous extract of garlic reduced not just their total and LDL cholesterol, but also brought down their triglyceride levels.5
  • That said, there are also studies which peg the results at a much lower figure, saying you should expect a total cholesterol-lowering effect of 4 to 6 percent, and not twice that amount as some studies have shown.6

Why Dont We Consider Cholesterol As An Enemy Of Health

We have already told you in the article that cholesterol is not bad for our health, in fact, it now seems to be the real enemy, although it has been severely criticized . Because of the wide variety), is that cholesterol is essential for our body.

It is a lipid that is very actively involved in various important functions of our body. For example, it is part of the plasma membrane, a precursor of sex hormones , a precursor of adrenocorticotropic hormones , a precursor of vitamin D and a component of bile salts, thus helping to digest fats.

Therefore, cholesterol is essential and only becomes a problem when blood cholesterol levels are high. In other words, it becomes a problem when total cholesterol levels exceed 200 mg/dL or low-density lipoprotein levels exceed 130 mg/dL.

On the other hand, your cardiovascular health risk is particularly high if your high-density lipoprotein level is below 35 mg/dL. 40 mg/dL for men women.

Together, they have more power to improve blood chemistry,” explains Rifkin.

Top 10 Cholesterol Lowering Foods

Cholesterol is a steroid lipid present in the blood, necessary for the proper functioning of cell membranes and the production of vitamin D and certain hormones.

High cholesterol levels are a risk factor for heart disease and stroke. Cholesterol-lowering foods are therefore a great addition to anyones diet for optimal health and as a preventative measure.

Cholesterol-lowering foods include oat bran, flax seeds, garlic, almonds, walnuts, whole barley, and green tea. Below is a detailed list of foods which lower bad LDL cholesterol, while leaving the good HDL cholesterol largely unaffected.

The Verdict: Garlic Helps But Wont Do It Alone

Can Garlic Help to Lower Cholesterol?

Some researchers say that taking garlic as a supplement with a view to lowering lipid levels cannot be widely recommended as the evidence isnât strong enough.14 They warn that you shouldnât expect to see a miraculous change in your cholesterol numbers. It might help, but may not be good enough to warrant going off any of your medication.

Incidentally, there has been a lot of debate around whether high cholesterol levels do have an adverse effect on your heart health and longevity. While the cholesterolâheart disease conundrum is yet to be resolved, what is emerging is that you need to keep an eye on chronic inflammation that your body is subjected to, be it through processed and refined foods, stress, or a sedentary lifestyle. One hypothesis considers chronic inflammation the trigger for increased cholesterol production. High cholesterol or hypercholesterolemia is, in turn, also linked to increased inflammation.15 It may also affect your liver and kidney and increase the risk of obesity and diabetes. Fortunately, garlic may have a positive impact here thanks to its anti-inflammatory properties, helping counter the inflammation.16

The bottom line? Donât expect garlic to be a miracle cure or a free pass to ignore your cardiovascular health. That said, it is a good addition to your diet as part of a holistic plan to improve your cholesterol levels, alongside lifestyle changes and other dietary interventions.

What About Garlic And Cholesterol

While some studies have shown that garlic can benefit cholesterol levels, more research is needed. In particular, scientists are looking to learn more about its long-term effect on cholesterol and the heart.

Cholesterol is a waxy substance that circulates in your blood. There are two types of cholesterol: “bad” cholesterol, or LDL cholesterol, and “good” cholesterol, or HDL cholesterol. Having too much LDL cholesterol and low levels of HDL cholesterol in your blood can raise your risk for severe health problems.

A 2016 study published in the International Journal of Preventive Medicine concluded that a garlic-lemon juice mixture may benefit cholesterol. The small study, which involved 112 people ages 30-60, showed that garlic and lemon juice helped decrease total cholesterol and lower blood pressure. However, researchers recorded the results after only eight weeks.

An analysis of studies done between 1955-2013 also showed that garlic “moderately to significantly” lowers total cholesterol and LDL cholesterol levels. When taken for more than two months, the garlic helped reduce total cholesterol by 8%.
