Water: Water's calorie-free status is hard to disagree with. Hydration is also vital for blood sugar regulation.
Coffee: Coffee's phytochemicals may protect liver and pancreatic cells against fatty liver and sustain insulin activity.
Black Tea: Tea components reduce inflammation, oxidative stress, and insulin resistance. Tea components may be used to make diabetes-management solutions.
Green Tea: Catechins in tea may lower blood sugar through blocking carbohydrate absorption, improving glucose metabolism, and reducing oxidative stress.
Milk: Slow digestion and insulin response enhance blood sugar levels with casein and whey proteins.
Tomato Juice: Tomato juice 30 minutes before eating a carbohydrate-rich breakfast had lower blood sugar results than those who drank water.
