Recently I came to know that tea can help prevent diabetes. I normally substitute the quart packets of the sugar free instant lemonade and the sugar free instant Tang or any other orange drink that I sometimes buy from the supermarkets and make them minus the sugar. It only takes one tablespoon to make a great, refreshing cup of tea. But still I want to find new and interesting ways to make my tea more healthier. Can you tell me how do I make an Irish coffee recipe or tea mix apt for a diabetic, my friend is 36yr old male and is diabetic, I want him to have it but I am concerned about his health. Can you also tell me about more ways like the ones I have mentioned above that will help me prevent calories and diabetes?
