Anti-Cancer Foods: What to Eat to Lower Your
Cancer Risk
Introduction
Cancer remains one of the most significant public health
challenges of our time. Although genetic factors contribute to cancer
development, studies show that diet plays a major role in up to 30–40% of
cancer cases. This means that the foods you choose every day can either
increase or decrease your cancer risk.
Fortunately, certain foods are rich in nutrients,
antioxidants, phytochemicals, and fibers that help your body fight
inflammation, neutralize harmful molecules, repair DNA damage, and strengthen
immune defenses. Researchers call them anti-cancer foods, and they can
play a powerful role in long-term disease prevention.
In this comprehensive guide, we explore the most effective
anti-cancer foods, how they work, and how to easily integrate them into your
daily meals. Whether you're just starting a healthier lifestyle or looking to
enhance your current habits, this article provides all the information you
need.
