Although our bodies require glucose for energy, we do not need to consume simple sugars in order to obtain it. Complex carbohydrates, such as breads and cereals, fruits and vegetables provide vitamins, minerals and fibre in addition to plenty of glucose for energy. Eating too many of these empty calorie foods could decrease your appetite for more nutrtious foods and result in health problems down the road. However, sugar can be incorporated into a well-balanced diet in moderation. So, the fact remains that we cannot obtain a healthy, balanced diet on sugar alone.
Some people believe that sugar alone causes cavities.
Tooth decay can be caused by any carbohydrate-containing food, not just sugar. Sticky foods such as raisins or bread can be the worst culprits. Eating a variety of healthy snacks and brushing teeth daily with a fluoride toothpaste are your best defenses against tooth decay. Although this theory was suggested in the 1970's, research has failed to prove it. No behavioural differences have been noted between children who have eaten large amounts of sugar and those who have not.
