Medium Purine Foods – Eat in Moderation
Fresh and saltwater fish, shellfish, eel, meat, poultry, meat soups and broth, asparagus , mushrooms, cauliflower, spinach, legumes, oatmeal, bran, wheat germ, whole-grain breads and cereals, eggs.
Low Purine Foods – No Restriction
Breads and cereals (low-fiber, white flour, or refined grain types), nuts, peanut butter. Vegetables not high in purines, soups – cream style or vegetable without meat extract, coffee, tea, fruit juices, soft drinks, gelatin, sugar, low fat cheeses.
Gout Diet – Foods That May Help
Some people have found cherry juice or strawberries helpful. Some chemicals contained in dark berries may help reduce the inflammation and lower the uric acid.
Oily fish like salmon, or fatty acids in flax seed or olive oil or nuts may reduce inflammation too.
It has been suggested that using tofu (from soybeans) instead of meat could also be helpful.
Some have found relief with OPC3 antioxidant supplement.
