Garlic’s Impact on Blood Sugar and Cholesterol Levels Revealed in New Study

In a recent study published in the journal Nutrients, researchers in China conducted a systematic review and meta-analysis to explore the effects of garlic on blood lipid and glucose levels in humans.


Chronic diseases like cardiovascular diseases, cancers, and diabetes cause millions of deaths yearly. Dysregulation of glucose and lipids can lead to serious health issues. Garlic, containing compounds like allicin, shows promise in regulating glucose and lipids. Further research is needed to fully understand the benefits of garlic.

About the Study

The study searched four databases for relevant trials related to garlic, glucose, and lipid metabolism. Inclusion criteria involved randomized clinical trials with specific outcomes and involved adults over 18 years old with a placebo control group. Data analysis was conducted, and significant results were found in terms of garlic’s impact on blood glucose and lipid levels.

Study Results

A total of 1,567 participants from various countries were included in the analysis. The study showed that garlic had a positive effect on fasting blood glucose, Hemoglobin A1c, total cholesterol, LDL cholesterol, and HDL cholesterol levels. However, there was no significant impact on triglyceride levels. The study confirmed the benefits of garlic on blood sugar and lipid profiles.


In summary, garlic was found to improve various aspects of blood sugar and cholesterol levels. Despite some limitations, the study highlighted the positive effects of garlic on overall health.
