Why Fruit Matters
What nutrients in fruit fight cancer cells?
Fruits are natures multivitamin. Theyre loaded with:
- Antioxidants vitaminsC &E, flavonoids, anthocyanins that neutralize free radicals.
- Polyphenols plant compounds shown to slow tumor growth in lab studies.
- Fiber keeps digestion moving, which is vital when treatment causes constipation.
- Water helps stay hydrated, especially during chemotherapyinduced nausea.
All of these work together to protect DNA, reduce inflammation, and support healthy cell turnover. For a deeper dive, see .
How do these nutrients act on cancer cells?
Think of antioxidants as tiny bodyguards, patenting the doors to your cells so harmful free radicals cant break in. Polyphenols, on the other hand, act like traffic cops, slowing down the signals that tell cancer cells to multiply. Fiber feeds good gut bacteria, which in turn produces shortchain fatty acids that have antiinflammatory effects.
