Can red dates and onions be eaten together?
Generally speaking, red dates and onions can be consumed together, but excessive consumption should be avoided. The specific analysis is as follows:

Both red dates and onions are nutritious ingredients. Red dates are rich in vitamin C, iron, and dietary fiber, which help nourish the blood and improve complexion. Onions contain sulfides and various vitamins, offering antioxidant and lipid-lowering effects. When consumed together, they typically do not cause adverse reactions; rather, they can provide diversified nutrients and enhance immunity.
However, both red dates and onions contain a certain amount of dietary fiber, and onions are irritating. For patients with gastrointestinal diseases such as gastritis and gastric ulcers, excessive consumption of these two foods may increase the gastrointestinal burden, leading to discomfort symptoms such as abdominal distension and pain. Therefore, individuals in this category should control their intake or adjust their dietary structure according to a physician's advice.
In daily diets, balanced intake of various foods and attention to food pairing can better meet the body's nutritional needs and promote health.
