In hypoglycemia, blood sugar levels fall below normal. Symptoms such as shakiness and headaches may occur. Sugars do not unusually affect blood sugar levels in healthy persons. Low blood sugar levels occur most often in people with diabetes who take too much insulin. The treatment in this case is to eat sugars such as those found in fruit juice, sugar cubes, hard candy or soft drinks.
Tooth decay is the result of many factors, including heredity and the make-up and flow of saliva.
Sugars and other carbohydrates such as starchy foods also play a part. The acids then break down the tooth to form a cavity. Frequent snacks of foods that contain carbo-hydrates, especially those that stick to the teeth, may increase chances of decay. The use of fluoride and better dental care has led to a decline of tooth decay in recent years. Experts also advise a balanced diet and brushing teeth after meals and snacks.
