Direct Answer:
Besides water, diabetics can enjoy unsweetened tea, coffee, sparkling water, infused water, and low-calorie beverages like herbal tea or diet drinks in moderation. These provide variety without raising blood sugar.
Why This Matters:
Drinks are a major source of hidden sugar. Choosing the right beverages helps prevent unintentional glucose spikes and supports hydration—key for kidney and metabolic health.
Evidence-Based Explanation:
A Diabetes Care review found that sugary beverages contribute significantly to A1C increases, while unsweetened coffee and tea are linked to improved insulin sensitivity. Small amounts of low-calorie sweeteners (like stevia or sucralose) are considered safe in moderation.
Practical Drink Ideas:
- Sparkling water with lemon, cucumber, or mint
- Iced green tea or black tea with no sugar
- Black coffee or coffee with unsweetened almond milk
- Electrolyte water with no added sugar
Drinks to Limit or Avoid:
- Fruit juice and soda
- Sweetened iced tea or energy drinks
- High-sugar smoothies
