They need to read the labels. Don't just look for products that do not have sugar in them. Look for products with a lower carbohydrate content. That is the key to sustaining normal blood sugar levels. I firmly believe diabetes can be controlled through diet and exercise.
Many diabetics eat wrong.
They are still eating sugar, drinking alcohol, and making poor nutritional choices. Some of them offset their increased sugar levels with more insulin. This is only worsening their condition. Hypoglycemics need foods which will raise their blood sugar level. Many people with low blood sugar problems will not eat breakfast and wait long periods of time between meals.
