Introduction
Onions are rich in sulfides, vitamin C, and dietary fiber, while broad beans contain plant protein, minerals, and carbohydrates. The components of these two foods do not conflict, and consuming them together in moderation can provide essential nutrients and promote gastrointestinal motility for the general population. Generally, no adverse reactions occur if they are thoroughly cooked. Combining these ingredients not only enhances flavor but also supplies various nutrients necessary for the human body.

Generally speaking, onions and broad beans can be eaten together. The specific details are as follows:

Onions and broad beans are both common vegetables with rich nutritional value. Onions contain abundant vitamin C, vitamin B6, potassium, dietary fiber, and other nutrients, while broad beans are rich in protein, vitamin A, vitamin C, iron, and calcium. When consumed together, they not only taste delicious but also provide various nutrients essential for the human body, helping to enhance immunity and promote digestion.

For individuals with sensitive digestive systems or gastrointestinal diseases, consuming large amounts of onions and broad beans simultaneously may increase the burden on the gastrointestinal tract, triggering or worsening symptoms such as indigestion, bloating, and diarrhea. For patients with favism (G6PD deficiency), eating broad beans may lead to severe symptoms such as hemolytic anemia. Additionally, spicy and irritating foods like onions may exacerbate the condition of patients with favism, so they are not recommended to be consumed together in such cases.

In daily life, before trying new food combinations, it is advisable to assess whether they are suitable for your own constitution and health status to avoid adverse reactions.
