1. Role of Nutrients in Cancer Prevention

Certain nutrients can help protect cells from damage that may lead to cancer:

Antioxidants: Found in fruits and vegetables, antioxidants like vitamins C, E, and beta-carotene neutralize free radicals, which can damage DNA and trigger cancer development.

Fiber: High-fiber foods, such as whole grains, beans, fruits, and vegetables, support healthy digestion and may lower the risk of colorectal cancer.

Phytochemicals: Compounds like flavonoids, carotenoids, and polyphenols found in plant-based foods can inhibit cancer cell growth and reduce inflammation.

2. Foods Linked to Higher Cancer Risk

Some dietary choices have been associated with an increased risk of certain cancers:
