Raw and cooked onions have certain benefits and have high nutritional value, so you can choose according to your personal preference, but for people with weak gastrointestinal function, you can try to avoid eating them raw to reduce gastrointestinal discomfort. In general, it is recommended that onions be eaten raw with other vegetables seasoned with condiments. Onions are a common vegetable with a pungent taste and contain more nutrients, including vitamins, fiber, and a variety of minerals such as zinc and selenium, so eating them raw is good for human health. However, for people with poor gastrointestinal function, it is recommended that onions be cooked as much as possible before consumption. Cooked onions are less pungent, which makes them easier to eat and reduces the stimulation of the gastrointestinal mucosa, which can cause bloating, abdominal pain and other discomforts. Cooking can also stimulate the special smell of onions, which can increase appetite, while dietary fiber can promote gastrointestinal peristalsis to improve digestive function. Onions contain more nutrients, so if you like onions, you can eat them raw or cooked with various vegetables in your daily life to ensure a comprehensive intake of nutrients.
