Cancer cells can be adversely affected by compounds in chilli and peppers and show promise for treatment according to new research at the University of Pittsburgh. Researchers there have discovered that capsaicin (the compound that gives chilli peppers their heat) caused pancreatic cancer cells to die through a process called apoptosis. Another US study conducted at the University of California, found that capsaicin stopped the spread of prostate cancer cells. We know that many spices such as ginger, are beneficial in fighting infection and stimulating the immune system, so for good preventive care put chilli on the menu and spice up your diet, and your health.
