My father has prediabetes. Can he drink fresh coconut water empty stomach thrice a week? He is not taking any kind of added sugar including honey. He eats 2-3 apples a day , 1 banana ,1 pear as a natural sugar a day. He is avoiding white rice too. He is trying his best to reverse his prediabetes. What other things he can do to reverse this prediabetes? PS- Our family don't have any history of diabetes . Not even our close family member has diabetes. From last many years he is doing proper exercises. He walks a lot. I am surprised how he got prediabetes.
