Prevent Cancer

A study suggests that regular consumption of French beans may reduce the chances of cancer. French beans get their green colour from a molecule called chlorophyll. Chlorophyll molecules have anti-cancerous properties. They can help block carcinogens in our bodies, which may cause cancer. Chlorophyll can bind to the carcinogen and prevent its absorption in the body. Instead, they get eliminated as toxic waste products. Therefore, French bean consumption may lower your risk of cancer.

Serotonin, dopamine and norepinephrine levels are essential for good brain health. However, sometimes their levels may reduce in the brain, leading to mental health disorders like depression.
