Raisin Bran Cereal
Raisin bran contains high levels of sugar and processed carbs. 1 cup of raisin bran contains more than 40 grams of carbs and 18 grams of sugar. Taking it regularly can result in blood sugar spikes. Studies show that there’s more grams of carbs in a half-ounce of raisins vs chocolate chips. Raisins are known to increase blood sugar levels so fast that they can be used to treat hypoglycemia (low glucose levels). Raisins are considered a wholesome source of carb by comparison. However, they are still known to increase your blood sugar levels.

When encountering new foods or activities, be vigilant about checking your blood glucose levels before and after to see how your body responds. Talk to your healthcare provider immediately if you notice any signs of hyperglycemia (high blood glucose levels).
