People with insulin resistance can eat grapes in moderation or in small quantities when their blood sugar is under stable control, and should avoid eating too much to prevent a sudden rise in blood sugar. Insulin resistance refers to the reduced sensitivity to insulin of the organs that utilize insulin (such as liver, muscle, fat and other tissues), which prevents blood glucose from stabilizing within the normal range. Grapes have a glycemic index of 43, which is a low glycemic index fruit. For insulin-resistant people with stable blood glucose control, they can be eaten in moderation or in small quantities, but excessive consumption should be avoided, which is not conducive to blood glucose control and is detrimental to the body. If people with insulin resistance have abnormal blood glucose or feel unwell, they should consult a doctor in time and seek professional help.
