1. Avoid eating foods with high purine content: animal viscera (liver, intestine, kidney and brain), seafood (abalone, crab, lobster, octopus, sardine, tuna, carp, perch, trout and cod), shellfish and meat (cattle, sheep, ducks, geese and pigeons).

2. Avoid eating foods with high cholesterol: animal viscera (liver, intestine, kidney and brain), fat meat, squid, fish and cuttlefish.

Avoid eating acidic foods, such as coffee, fried foods and high-fat foods. Acid-base imbalance will affect the body function and increase the burden of liver and kidney. Eat more vegetables and coarse grains.
