Sugar and Sweets

Many people are born with a “sweet tooth.” Soon after birth, babies show a preference for sweet solutions (such as breast milk). Most adults also naturally seek and enjoy sweets. Many parents worry about their kids eating sugar, candy, and desserts. A common misconception is that eating sugar is harmful or shows a lack of self-control. As long as they are eaten in moderation, sweets are not bad. The body and brain needs sugar to function.

Sugar is naturally present in most foods except meat. Lactose is the type of sugar found in milk, fructose is the sugar in fruits, and maltose is the sugar in grain products. Sucrose, the sugar refined from sugar cane and sugar beets, has no greater adverse effect on body function than any of the other sugars. Any food where sucrose, fructose, glucose, corn syrup, honey, or other sugars are listed as the first ingredient on the packaging can be defined as sweets.

Side Effects of Sugar

The main risk associated with eating sweets is increased tooth decay. This risk can be greatly reduced if your child drinks fluoridated water and brushes his teeth properly after eating foods that contain sugar. Foods that cause the most dental cavities are those that stick to the teeth (for example, raisins and caramels).

Your child is at greatest risk of tooth decay if he falls asleep or walks around with a bottle of sugary liquid in his mouth (such as fruit juice, Kool-Aid, or milk). Constant access to a sippy cup filled with a sugary drink can also cause tooth decay.

If your child eats a lot of sugar all at once, he may have a temporary fall in his blood sugar level about 2 hours after eating the sweets. This fall in blood sugar may cause sweating, hunger, dizziness, tiredness, or sleepiness. This reaction is brief and harmless and is relieved by the passage of time and by eating a food containing some sugar, such as fruit juice. These symptoms do not occur after eating a normal amount of sweets; nor do they occur in everyone.

Myths About Sugar

Eating sweets in moderation is basically not harmful. Candy does not cause cancer, heart disease, or diabetes. The following are some common issues many parents are concerned about.

  • Obesity

    Obesity is caused by overeating in general and is not specifically related to eating sweets. In fact, fatty foods have twice the calories of sugary foods per given amount. However, because of the availability of sweets in our society (especially sweet drinks) and the pleasure associated with eating them, sugary foods eaten in excess are a major factor in our obesity epidemic.

  • Hyperactivity

    Extensive research has shown that sugar and chocolate do not cause or worsen hyperactivity. In fact, consuming a lot of sugar such as a 12-ounce soft drink (containing 10 teaspoons of refined sugar) may cause a temporary relaxed state or even drowsiness.

  • Junk food

    The term “junk food” has led to considerable confusion in our country. Some people consider any kind of sweet or dessert to be junk food. They claim that these foods lack nutritional value. While that is true for some sweets (candy), it is not true for others (such as peach pie). Eating sweets in moderation is not harmful.


Note: These guidelines do not apply to children who have diabetes.

  • Allow sugar in moderation.

    In general, eating any food in moderation is healthy. Eating too much of any one kind of food is unhealthy.

    It is probably a good idea to avoid giving your child sweets before he is 1 year old. If sweets are included in your child’s diet too early, they may interfere with the child’s willingness to sample new foods that are unsweetened.

  • Don’t forbid sugar completely.

    Some parents forbid sweets in hopes of preventing a preference for them. However, because this preference is present at birth, we have little influence over it. Forbidding sweets completely may increase a child’s fascination with them and cause candy binges. With candy and other sweets so readily available in stores and vending machines, sugar consumption can’t always be monitored. A taboo against sugar becomes unenforceable as a child grows older. If a parent makes an issue of it, it becomes an unnecessary battle.

  • Limit the amount of sweets you buy.

    The more sweets there are available at home, the more your child will eat. Try to purchase breakfast cereals and cookies in which sugar is not the main ingredient.

  • Limit the amount of sweets your child eats.

    While one candy bar is fine, eating an entire bag of candy is unacceptable. Try to eliminate binging on candy and sweets. You can best do this by setting a good example. Make exceptions and allow extra candy on Halloween and other holidays, birthdays, and at parties. The worst that could happen is your child could become extra sleepy.

  • Allow sweets for desserts.

    Sweets can cause physical symptoms only if they are eaten in excess. As long as they are eaten after a well-balanced meal, they cause no symptoms. An acceptable dessert can be just about anything, including cookies, cake, or even a candy bar.

  • Discourage sweets for snacks.

    Candy, soft drinks, and other sweets are not good choices for snacks. Keep plenty of nutritious snacks and drinks (such as fruits juices, yogurt, graham crackers, oatmeal cookies, and popcorn) on hand, and set a good example yourself. Most cookies are OK for snacks if the main ingredient is flour.

  • Insist that the teeth are brushed properly after eating sweets.

    Unless you encourage this good habit, a “sweet tooth” can become a decayed tooth.

Special Benefits of Sugar

Some children will take bitter medicine more easily when it is mixed with something sweet, such as chocolate pudding or pancake syrup.

Call Your Child’s Healthcare Provider During Office Hours If:

  • Your child frequently binges on sweets.
  • You find yourself repeatedly nagging your child about sweets.
  • You think your child has a problem with sugar.
  • You have other questions or concerns.
