Osteoarthritis in Traditional Chinese Medicine (TCM) is generally divided into two main categories. The first category is liver and kidney deficiency, commonly seen in older adults. For this condition, it is advocated to consume foods that nourish the liver and kidney. Black foods are considered to benefit the kidneys, such as black rice, black beans, black goat, and black pork. Other foods like He Shou Wu (Polygonum multiflorum), Rehmannia glutinosa, Coix seed, and Chinese yam also help nourish the liver and kidney and can be beneficial for the condition. The second category is Qi stagnation and blood stasis type, where it is recommended to eat foods that promote blood circulation and remove blood stasis. In Western medicine, there are no specific dietary recommendations for treating osteoarthritis, except for general advice for elderly women to consume calcium-rich foods to prevent bone-related issues. Foods recommended include milk, eggs, and lean meat, which are rich in protein and calcium, and it is encouraged to consume more of these.
