How Garlic Keeps Your Blood Sugar and Cholesterol Low
Adding some garlic to your diet has been found to lower blood sugar and
cholesterol levels. A new meta-analysis, a research approach that
combines data from many studies, revealed favorable findings on garlic
intake.
Researchers from Southeast University and Xizang Minzu University in
China examined 22 previous studies, which included 29 randomized
controlled trials. Their findings suggest that frequent garlic
consumption may be linked to lower blood sugar levels and lower amounts
of certain cholesterol types.
Blood sugar and blood lipids, primarily glucose and cholesterol, are
essential elements for human health. Glucose is the body's major source
of energy, whereas lipids are the building blocks for cell membranes and
hormones. However, modern dietary habits can contribute to an imbalance
in these essential components, leading to an increased risk of various
health issues. Furthermore, lifestyle choices other than diet can
significantly affect blood sugar and cholesterol levels, such as alcohol
consumption and exercise patterns.
Glucose and lipid metabolisms are meticulously controlled in healthy
individuals, as noted by the researchers in their published paper.
"Disorders of glucose and lipid metabolism can lead to a number of
chronic diseases, including atherosclerosis, diabetes and fatty liver
disease," they add.
Garlic has a long history of being associated with good health. Previous research, albeit conducted in isolation, suggested that it may have a role in regulating blood lipids and glucose levels. This new study builds upon this existing body of evidence.
Analysis of the cumulative studies validated the benefits of garlic
consumption. Individuals who incorporated garlic into their diet had
significantly lower blood glucose levels, indicating better long-term
control. They also saw an increase in HDL (good) cholesterol, a drop in
LDL (dangerous) cholesterol, and a reduction in total cholesterol
levels.
Interestingly, triglyceride levels did not appear to be considerably
affected. However, it is important to acknowledge that the current
evidence cannot conclusively prove a cause-and-effect connection. In
other words, we can't say for certain that eating more garlic lowers the
risk of heart disease.
However, the association strongly suggests that including garlic in our
diets might be a delicious way to manage glucose and cholesterol levels.
Further research with more focused studies is needed to explain the
precise mechanisms at play. The studies included in the meta-analysis
used various types of garlic, such as fresh cloves, aged extracts, and
powdered pills, with durations ranging from three weeks to a year.
Garlic also contains alliin, an antioxidant molecule associated with
blood glucose, blood lipids, and the gut flora. The combined impact of
these processes is likely responsible for the favorable results seen in
the study.
The importance of diet in influencing health outcomes, both positive and negative, is undeniable. This new study provides further reasons to incorporate garlic into our diets.
“[The study] provides new ideas for the development of natural products
against diseases related to glycolipid metabolism,” write the
researchers.
