A compound found in everyday foods can slow the development of cancerous tumors.  A 2005 study conducted by scientists at the University College of London's Sackler Institute (United Kingdom) found that inositol pentakisphosphate, present in beans, nuts, and cereals, can inhibit an enzyme that is necessary for tumors to grow.

Each day, try to eat foods rich in inositol pentakisphosphate: 1 cup (226 gm) of beans (such as lentils and peas), 1⁄2 cup (113 gm) of nuts (almonds, and hazelnuts [filberts] are also good sources of Vitamin E - see Tip 31) and 6 ounces (170 gm) of whole-wheat cereals (for the wheat bran).

In the US, cancer has surpassed heart disease as the leading cause of death for those 85 years of age and under. ~ US National Center for Health Statistics
