New research.

Thanks to the scientists and researchers who continue to find new horizons of different subjects. The researchers reviewed the existing studies about garlic to find how garlic affects on human health. They centralized their attention how garlic consumption effects on human cholesterol , blood glucose and triglyceride  levels.

A research based in China , collected data from 29 trials to find how garlic affects on cholesterol, blood glucose, hemoglobin A1c (HbA1c) and triglyceride. The study appears in the journal Nutrients. 

According to previous studies, it was known that garlic has a compound known as Allicin. This compound has some properties like antibacterial  , antifungal and antiviral. To find out if garlic has any effects to improve blood glucose and lipid metabolism, the researchers conducted 22 study  meetings . There were 29 trials to focus on the subject. The 1,567 participants were from different countries and age groups  18 and alders . The participants needed eat/drink garlic for more than 2 weeks and report their HbA1c, fasting blood sugar, total cholesterol, high-density lipoprotein ( HDL) , low- density lipoprotein cholesterol ( LDL) and triglyceride.

The participants were given garlic in different form during trial like:

  • Garlic powder.
  • Garlic oil.
  • Old garlic extract.
  • Garlic powder pill or tablets.
  • Garlic extract capsule.
  • Raw garlic.

Some participants consumed 300 to 22,400 mg of garlic in one day. While other consumed 800 to 4,200 mg per day.

The researcher used all these data to find out if garlic consumption could improve metabolic markers. The found that:

  • Garlic supplements lowered fasting blood glucose levels.
  • Garlic lowered HbA1c levels.
  • Garlic reduced total cholesterol levels.
  • Garlic lowered LDL, also known as ” bad cholesterol ” .
  • Garlic increased HDL levels ,   known as ” good cholesterol.
  • The researchers did NOT find any impact on TRIGLYCERIDE levels.
  • Researcher also found that garlic consumption may have the potential for use in preventing or managing some cardiovascular and metabolic disorders.

Dr. Cheng-Han Chen, MD,  a board-certified interventional cardiologist and medical director of the Structural Heart Program at Memorial Care Saddleback Medical Center in Laguna Hills, CA said in his own words as under;

“This meta-analysis included  many different trials that studied the effects of garlic. However , these studies varied quite a bit in their designs, and thus do not allow us to pinpoint the exact active compounds that could be responsible for garlic’s beneficial effects. Experts believe garlic has beneficial effects on blood sugar control and cholesterol levels through its sulfur-based compounds, such as allicin, alliin and diallyl disulfide , but that more research is necessary to learn exactly how it works. This study is unlikely to change our specific dietary recommendations, but it should be noted that garlic would be considered a nutritious and healthy addition to any diet “.
