Can patients with high blood sugar eat onions?

Generally speaking, patients with high blood sugar can eat onions, but should avoid consuming excessive amounts. Detailed analysis is as follows:

Onions contain abundant sulfides, vitamin C, dietary fiber, and trace elements. Moreover, quercetin and sulfides in onions may help control blood sugar by enhancing insulin sensitivity and inhibiting glycogen breakdown. If patients with high blood sugar have well-controlled blood glucose levels and experience no fluctuations or adverse reactions after consuming onions, moderate onion consumption is acceptable.

However, onions have a pungent flavor that may irritate the gastric mucosa and cause gastrointestinal discomfort. Particularly for patients with stomach conditions such as gastric ulcers, excessive onion consumption may worsen their condition. Additionally, components in onions may cause gastrointestinal gas accumulation, leading to discomfort such as abdominal distension and pain. Therefore, it is recommended to consume onions in moderation daily and choose appropriate cooking methods, such as stir-frying before consumption.

Patients with high blood sugar should choose appropriate methods and quantities of onion consumption based on their individual health status and blood glucose control. At the same time, they should regularly monitor blood glucose levels and adjust their dietary structure accordingly.
