Nutrition Principles
Purple Produce
Dark purple fruits and vegetables contain powerful antioxidants.
What
Purple produce (blueberries, blackberries, red cabbage, purple sweet potatoes) contains anthocyanins — potent antioxidants that reduce oxidative stress and inflammation.
Why
Anthocyanins scavenge free radicals, reduce inflammatory markers, and may support cellular health. In serious illness contexts, reducing oxidative stress is beneficial.
Evidence
Multiple studies show anthocyanin-rich foods reduce CRP, LDL oxidation, and improve endothelial function. The Mediterranean diet's emphasis on colorful produce is associated with better outcomes.
Implementation
2-3 servings daily of purple/dark colored fruits and vegetables.
Caution
No significant cautions. Start gradually if increasing fiber intake significantly.
