GRAPES -- FOODS THAT FIGHT CANCER


OTHER FOODS THAT FIGHT CANCER


NOTE: No single food or food substances can protect you against cancer. But scientists believe that the right combination of foods in a predominantly plant-based diet may. Evidence is mounting that the minerals, vitamins and phytochemicals in plant foods interact to provide extra cancer protection. This concept is called synergy. In addition, vegetables, fruits, whole grains and beans are low-energy-dense, low calorie foods and probably protect against weight gain. According to the Second Expert Report, experts believe that weight gain particularly obesity and overweight are implicated in the development of cancer. Eating a predominantly plant based diet can help prevent weight gain and therefore protect against those cancers whose risk is convincingly increased by higher body fat (namely cancers of the colorectum, esophagus, endometrium, pancreas, kidney, and breast in postmenopausal women). That is why AICR recommends that at least 2/3 of your plate should be filled with vegetables, fruit, whole grains and beans.

Grapes and Grape Juice

Both grapes and grape juice are rich sources of resveratrol, a specific type of natural plant chemical that belongs to a much larger group of plant chemicals called polyphenols.

The skin of the grape contains the most resveratrol, and red and purple grapes contain significantly more resveratrol than green grapes. Grape jam and raisins contain much smaller amounts of this phytochemical. Wine also contains resveratrol. However, with AICR’s second expert report noting convincing evidence that alcohol is associated with increased risk for cancers of the mouth, pharynx and larynx, esophagus, breast (pre- and postmenopausal) and colon and rectum (in men), wine is not a recommended source of resveratrol.

Scientists believe that polyphenols in general and resveratrol, in particular, possess potent antioxidant and anti-inflammatory properties. In laboratory studies, resveratrol has been able to prevent the kind of damage known to trigger the cancer process in cell, tissue and animal models.

Other laboratory research points to resveratrol’s ability to slow the growth of cancer cells and inhibit the formation of tumors in lymph, liver, stomach and breast cells. Resveratrol has also triggered the death of leukemic and colon cancer tumors.

In one series of studies, resveratrol blocked the development of skin, breast and leukemia cancers at all three stages of the disease (initiation, promotion and progression).

The Research

AICR has funded research on the following topics relating to grapes and the cancer-fighting components they contain. Click each topic to search for relevant AICR-funded research studies performed to date.
