Generally speaking, patients with fatty liver disease can eat onions, but they should be consumed in moderation. The detailed explanation is as follows:
Onions are a common vegetable rich in various nutrients, such as vitamin C, vitamin B6, folic acid, potassium, and sulfides. These components are beneficial to human health and will not adversely affect patients with fatty liver disease when consumed in moderation. On the contrary, the nutrients in onions help maintain normal physiological functions and provide necessary nutritional support to the body.
The sulfides in onions have antioxidant and anti-inflammatory properties, which can help reduce oxidative stress and inflammatory responses in the liver—this is beneficial for patients with fatty liver disease. The livers of patients with fatty liver disease are often in a state of chronic inflammation and oxidative stress; these components in onions may help alleviate this condition, thereby offering some protective effects to the liver. Additionally, the dietary fiber in onions can promote intestinal motility, aid digestion and excretion, and help reduce the metabolic burden on the liver.
Although onions are beneficial for patients with fatty liver disease, moderation is still important when consuming them. Excessive consumption may cause gastrointestinal discomfort, such as bloating and abdominal pain, especially for patients with fatty liver disease who have weaker gastrointestinal function. Moreover, the diet of patients with fatty liver disease should primarily be light and easily digestible, avoiding excessive intake of high-fat and high-sugar foods. When consuming onions, one can choose healthier cooking methods such as stir-frying with little oil or making cold salads, avoiding frying or adding excessive oil and seasonings.
