Vitamins, minerals and other nutrients are essential for good health and can help us to combat cancer and other diseases—but don’t plan on getting them in pill form. The research conducted to date has shown little to no cancer-fighting benefits from taking mineral, vitamin and other dietary supplements.
A few trials have shown a slight benefit of certain nutritional combinations in helping to prevent prostate cancer. But until further research proves otherwise, there is not enough evidence to justify spending money on supplements. In fact, there is evidence that dietary supplements can do more harm than good—as in the case of beta carotene, which has been shown to increase the risk of lung cancer in some people.
Instead, reduce your risk of cancer by focusing on evidence-based nutrition strategies: Eating at least five servings/2.5 cups of fruit and vegetables a day, getting adequate fibre, and limiting red and processed meats.
