Your liver performs 500+ functions: detoxification, protein synthesis, bile production, nutrient storage. Fatty liver affects 25% of adults — reversible with diet. Key liver-supporting nutrients: choline, betaine, glutathione precursors, selenium, milk thistle (silymarin).
Top Foods
| Food | Why | Do | Don't |
|---|---|---|---|
| coffee | 3+ cups/day reduces liver fibrosis 25-70%. Chlorogenic acid reduces hepatic fat and inflammation. Most studied liver-protective food. | 3-4 cups black per day | Don't add sugar/creamer — negates liver benefits |
| beetroot | Betaine (trimethylglycine) — methyl donor for liver detoxification phase 2. Reduces hepatic steatosis. Also nitrates → NO vasodilation. | Raw or cooked, 100g 3-4x/week | Beeturia (red urine) is harmless — don't be alarmed |
| broccoli | Sulforaphane activates Nrf2 pathway → upregulates detoxification enzymes (glutathione S-transferase). Reduces liver fat and inflammation. | Lightly steamed (3-4 min) — preserves myrosinase enzyme | Don't overcook — destroys sulforaphane-forming enzyme |
| egg | Choline (147mg/egg) — prevents hepatic fat accumulation via VLDL export. Choline deficiency directly causes fatty liver in humans. 2 eggs = 54% daily choline. | 2-3 whole eggs/day (yolk has choline) | Don't skip yolks — choline is in the yolk |
| walnuts | Omega-3 ALA + glutathione precursors (cysteine) + arginine. 30g/day improved liver enzymes (ALT, AST) in NAFLD patients in 12 weeks. | 30g/day (small handful) | Don't exceed 50g — calorie-dense |
