Gout patients can eat onions. Onions are a low-purine food that does not affect the uric acid level in gout patients or worsen their condition. Additionally, onions contain various nutrients and have benefits such as improving eyesight, reducing inflammation, and killing bacteria. Therefore, gout patients can safely consume foods like onions.

However, gout patients should avoid eating animal livers, kidneys, hearts, and lungs, as these foods are rich in purines and can easily increase uric acid levels or worsen gout symptoms. It is also crucial for them to strictly abstain from alcohol and reduce the intake of sugary drinks.

Instead, gout patients should focus on eating low-purine, alkaline, and high-potassium foods. They should also increase their intake of B vitamins and vitamin C.

Here are some specific dietary recommendations:

1. Consume more low-purine foods: Gout patients should prioritize eating low-purine foods such as cereals, eggs, dairy products, fruits, and vegetables.
2. Increase alkaline food intake: Alkaline foods are beneficial for uric acid excretion. It is recommended to consume at least 500 grams of vegetables daily, including green vegetables, carrots, cucumbers, tomatoes, and cabbage.
3. Boost B vitamin and vitamin C intake: Increasing the intake of B vitamins and vitamin C can help dissolve uric acid deposits in the body. Eating more vegetables and fewer carbohydrate-rich foods can help reduce purine intake while increasing vitamin C and fiber intake. Eating less carbohydrate-rich foods can also help control calorie intake, maintain weight, and promote weight loss and fat reduction.
4. Consume high-potassium foods: Foods like bananas, broccoli, and celery are rich in potassium, which can help reduce uric acid deposition and promote its excretion from the body. Additionally, it is recommended to consume plenty of alkaline foods such as seaweed, cabbage, celery, cucumbers, apples, and tomatoes.
