A study conducted at the National Institute for Health Research Bristol Nutrition found that men who ate more than ten servings of tomatoes or tomato products per week had an 18% lower risk of prostate cancer than men who ate fewer than ten servings.
Tomatoes contain a particularly high concentration of the powerful antioxidant lycopene, which effectively fights prostate cancer and reduces tumour growth in men with prostate cancer. Lycopene also contributes to the prevention of heart disease. Tomatoes are a good source of vitamins A, C and E, all enemies of cancer-promoting free radicals. So add some cherry tomatoes to your green salad with some feta and cucumbers and top your sandwiches with tomato slices, avocados and mozzarella. You can also mix them into a soup.
Both grapes and grape juice are rich in resveratrol, a phytochemical whose anti-cancer effects have been well studied and which is found in large amounts in the skin of grapes. Resveratrol is present in red, purple and green grapes, with the amount depending on the growing conditions rather than the colour or variety of the grapes.
Some researchers pointed to resveratrol’s ability to slow the growth of cancer cells and inhibit tumour formation in lymph, liver, stomach and breast cells. Resveratrol has also induced the death of leukaemia and colon cancer tumours.
