While no single food can guarantee cancer prevention, decades of research show that a diet rich in certain vegetables significantly lowers the risk of several cancers—including colorectal, breast, lung, and prostate. These four stand out for their powerful anti-cancer compounds, backed by science:
1. Broccoli (and Cruciferous Vegetables)
Key Compound: Sulforaphane
Found in broccoli, Brussels sprouts, cauliflower, kale, and cabbage.
How it helps:
Activates enzymes that detoxify carcinogens
Reduces inflammation and inhibits tumor growth
May slow progression of prostate and breast cancers (Journal of Nutritional Biochemistry, 2020)

2. Carrots
Key Compound: Beta-carotene (a precursor to vitamin A) + Polyacetylenes

How it helps:
High intake linked to lower risk of stomach, lung, and prostate cancers
Antioxidants neutralize free radicals that damage DNA
Polyacetylenes (like falcarinol) show anti-tumor effects in lab studies
