Quick answer: Nutrition is the most important part of supporting detoxification. Eat organic produce when practical, healthy fats, clean protein, plenty of fiber and fermented foods, and limit processed foods, sugar, alcohol and, for some people, gluten and dairy. Your liver relies on B vitamins, antioxidants, minerals and amino acids, and foods like cruciferous vegetables, garlic, beets and leafy greens supply them.
Foods to include
- Organic fruits and vegetables when practical
- Healthy fats: avocado, nuts, seeds, olive oil
- Clean protein: grass-fed meat, wild-caught fish, pasture-raised poultry
- Fiber to support regular bowel movements
- Fermented foods such as sauerkraut, kimchi and kefir
Foods to limit
- Processed foods
- Sugar
- Alcohol
- Gluten and dairy if they bother you
Key nutrients for liver enzymes
- B vitamins (B2, B3, B5, B6, B12, folate)
- Antioxidants: vitamins C and E
- Minerals: zinc, copper, selenium
- Amino acids: methionine, cysteine, glycine
- Phytonutrients: flavonoids and sulfur compounds
Foods that support the liver
- Cruciferous vegetables (broccoli, kale, cauliflower) contain compounds that support phase 2 enzymes
- Garlic provides sulfur compounds
- Turmeric contains curcumin, an antioxidant
- Beets contain betaine
- Leafy greens are rich in nutrients and fiber
- Citrus provides vitamin C
- Liver (organ meat) is rich in vitamin A, B12, iron and copper; eat in moderation, especially if pregnant
