Can people with diabetes drink lemon water?
People with diabetes can generally drink lemon water, but only in moderation—not excessively.
Lemons are rich in vitamin C, vitamin B1, and other nutrients, and have a relatively low sugar content. When prepared as lemon water, it is suitable for people with diabetes. Moreover, lemon water contains eriocitrin, which helps reduce levels of oxidized lipids in the kidneys, liver, and bloodstream of diabetic patients, thereby helping to prevent or mitigate diabetic complications. Additionally, drinking lemon water may help protect diabetic patients against cardiovascular diseases such as hypertension and myocardial infarction. Thus, lemon water is generally safe—and even beneficial—for people with diabetes, provided it is consumed in appropriate amounts. Excessive intake, however, may stimulate excessive gastric acid secretion, leading to symptoms like nausea and vomiting; in severe cases, it may damage the gastric mucosa, potentially causing gastritis or gastric ulcers.
When preparing lemon water, do not add sugar, as this may elevate blood glucose levels and trigger adverse symptoms.
