4. Garlic
Garlic has a long history of use as a medicinal plant, with roots tracing all the way back to ancient China and Egypt.
The main active compound in garlic is allicin, a plant compound that is largely responsible for garlic’s variety of health benefits.
Several studies have shown that garlic can regulate blood sugar as well as promote heart health.
In one animal study, diabetic rats were given either garlic oil or diallyl trisulfide, a component of garlic. Both garlic compounds caused a decrease in blood sugar and improved insulin sensitivity.
Another study fed garlic to participants both with and without heart disease. Results showed that garlic was able to decrease total blood cholesterol, triglycerides and LDL cholesterol while increasing HDL cholesterol in both groups.
Garlic may be useful in the prevention of cancer as well. One test-tube study demonstrated that allicin induced cell death in human liver cancer cells.
However, further research is needed to better understand the potential anti-cancer effects of garlic.
Summary
Studies show that garlic may help lower blood triglyceride levels. Some studies have also found that it could decrease blood sugar levels and may have an anti-cancer effect, although more research is needed.
