I. Reasons for Suitable Consumption
Dark teas such as Pu’er tea and Liupao tea have a relatively low glycemic index due to their unique processing techniques. The tea polysaccharides they contain help regulate glucose metabolism, making them beneficial for diabetic patients. During fermentation, dark teas also produce many substances good for the cardiovascular system, offering double benefits for diabetics with cardiovascular problems.
White tea, with its minimal fermentation, retains rich tea polyphenols and amino acids, providing strong antioxidant effects that may help improve insulin sensitivity. In addition, white tea has a lower caffeine content compared with other teas, so it is milder to the nervous system and suitable for patients who need stable blood glucose.
II. Precautions
When enjoying the benefits of dark tea and white tea, diabetic patients should keep these key points in mind:
Never add sugar, honey, or drink sweetened tea drinks (such as bottled green tea or fruit tea), as they can cause a sharp rise in blood glucose.
Control the amount and timing of tea drinking.
The recommended daily total volume is no more than 500 ml, consumed in separate portions (e.g., 200 ml each time).
Avoid drinking on an empty stomach.
It is advisable to drink tea 1–2 hours after meals to reduce stimulation to the gastrointestinal tract and blood glucose.Strong tea contains caffeine that may interfere with blood glucose stability, and tannic acid may reduce the absorption rate of some hypoglycemic medications.At least 1 hour should separate taking medicine and drinking tea.
III. Advice for Special Groups
For patients with concurrent diseases (such as gastric ulcer or heart disease), the type and amount of tea should be adjusted according to medical advice.For patients prone to hypoglycemia, white tea is preferred because of its lower caffeine content, which helps reduce the risk of discomfort.
