If you're a fan of apple juice, the apple cider variety is the best apple juice for diabetics. It is a safe bet for diabetics. The glycemic index (GI) value for apples is 36, and 41 for filtered apple juice, which is quite low. So, apple cider juice may not cause rapid blood sugar spikes (9). Apple cider, which is unfiltered and has some extra pulp, has extra health benefits, such as polyphenols, which may have some antioxidant properties (104). Since it’s fruit juice, diabetics should just enjoy it once in a while.
