Diet and Nutrition in the Child

Dietary Considerations

Caloric Requirements

doubleangle 666 5pxblock lrExperts recommend that from birth to at least age 1, an infant's diet consist of breast milk. Non-formula cow's milk is not recommended especially prior to 1 year of age. This is due to its ability to cause allergies, gastrointestinal tract bleeding, and because it lacks sufficient vitamins and essential fatty acids vital for infant development. If formula must be used, limit it to 1/3 of the day's total caloric intake.

Caloric requirements are:

  1. Infants: 80-140 kcal/kg/day
  2. Children: 40-90 kcal/kg/day
  3. Adolescents: 30-50 kcal/kg/day

Are Children Getting Enough Fruits and Vegetables

doubleangle 666 5pxblock lrA recent study shows that US children are not eating enough fruits and vegetables. In a week long study, eating habits of 168 preschoolers (group aged 2 and 5 years) were recorded. None of the children met the 5 daily servings of fruits and vegetables recommended. According to researchers, most children consumed just 2 servings of fruit and less than 1/2 of a serving of vegetables per day. Also, 1/2 of the total fruit servings generally were in the form of juice, which experts say, in excess can cause diarrhea, growth failure, failure to thrive, and obesity in some children. Researchers wrote, "Low intakes of fruits and vegetables were associated with inadequate intakes of vitamin A, vitamin C, and dietary fiber, in addition to high intakes of total fat and saturated fat." High consumption of fruits and vegetables has been shown to significantly lower the risk of many types of cancers. The researchers urge parents to provide their children with a wide variety and abundance of fruits and vegetables and be role models for their children by also eating moderate amounts of fresh fruits and vegetables.

The Truth Regarding Fruit Juices and Other Drinks

doubleangle 666 5pxblock lrAs stated in the "Are Children Getting Enough Fruits & Vegetables" above, fruit juices as well as other drinks can be harmful in the growing child. Fruit and non-fruit juices are high in simple sugars and deficient in complex carbohydrates, protein, fat and fiber. They also tend to be low in vital vitamins and minerals. This can result in the following:

  • diarrhea and intestinal bloating (due to difficulty digesting fructose and sorbitol)
  • caloric deficiencies (fill up on juice and not calorie dense food)
  • nutritional deficiencies (fill up on "nutritionally empty" juice products)
  • dietary imbalances (fill up on juice and do not eat adequate foods containing protein, complex carbs, fat)

Experts recommend adding small amounts of juice (2-3 tablespoons) to water if juice must be given to children. It should be noted that juice prior to bed contributes to the development of dental caries.

Food Allergies and Intolerances

doubleangle 666 5pxblock lrFood allergies and intolerances are common in infants and children. Foods that cause the most problems include:

  • dairy products (i.e. cow's milk and eggs)
  • pork and fish
  • citrus fruits
  • wheat and yeast
  • nuts
  • soy products
  • many food additives

Symptoms include diarrhea, vomiting, failure to thrive, runny nose, sneezing, asthma inducement, wheezing, and skin problems such as hives. As identifying foods causing the problems can be very difficult experts recommend slowly introducing infants and children to foods one at a time. This way problematic foods can be identified early on and with little question as to the food culprit.

Most commonly, cow's milk is the cause and should be avoided, especially in those under 1 year of age. Soy or rice milk can be substituted for those allergic to cow's milk.

Childhood Obesity

doubleangle 666 5pxblock lrThe rate of childhood obesity has been rising significantly over the last 30 years. Studies have shown that obesity in childhood dramatically increases the odds of obesity in adulthood, a condition which compromises health and overall well being. Obesity is a difficult condition to treat as it requires a very high level of self-discipline in order to overcome. It is thus especially important to prevent obesity from occurring during childhood or seeking immediate and effective treatment if it does exist. Obesity is defined as weighing more than 20% of your ideal body weight.

If obesity is present or is becoming increasingly evident, nutritional and fitness counseling should be sought immediately. In addition, parents should be role models for their children - eating healthy and engaging in regular physical activity.

Nutritional Supplementation


doubleangle 666 5pxblock lrAccording to the American Academy of Pediatrics, women should breast feed until at least the age of 1 year and should not feed infants under 1 year cow's milk. Doing this can lead to deficiencies of iron. Generally speaking, iron supplementation is not recommended for infants; excess iron can cause retardation of growth, increased bacterial replication in infections, and can also compete for uptake with other essential minerals in the gut.

Vitamin A

doubleangle 666 5pxblock lrVitamin A (retinol) is available in liquid form and is also added to most baby formulas. Occasional supplementation in infants and children is recommended if deficiency is suspected. Research has shown a single dose of 100,000 IU (International Units) in children under 12 months of age and 200,000 IU in children over 12 months of age can reduce the risk of death from measles and, according to a study on Brazilian children, can help treat severe diarrhea.

Vitamin B's

doubleangle 666 5pxblock lrVitamin B is passed to the fetus and to the baby (via breast milk) by the mother. Thus, if the mother is deficient so to can the baby become deficient. In the case of mothers with vitamin B deficiencies (more common in vegetarians and vegans), supplementation may be necessary for mother and child.

Vitamin D

doubleangle 666 5pxblock lrVitamin D is another vitamin in which there may be a deficiency. Generally, a deficiency is most common when the mother is a vegetarian and/or lacks adequate sun exposure. In both cases, supplementation of the mother and infant is recommended. Like vitamin K, vitamin D is usually given to infants at the time of birth.

Vitamin K

doubleangle 666 5pxblock lrIn some infants and neonates, including those with certain malabsorption disorders, vitamin K deficiency may occur. This can cause unexpected hemorrhagic disease (bleeding). Almost always, babies are given intramuscular vitamin K shots at birth to prevent this condition.

doubleangle 666 5pxblock lrZinc deficiencies can occur in infants whose mothers are deficient in zinc or if there exists a problem with zinc uptake from the mammary glands in the mother's breasts. Zinc deficiencies are also common in premature infants and children with malabsorption syndromes. Zinc deficiencies are generally not found in infants who breast feed, assuming the mother is not deficient. Signs of deficiency include:

  • skin lesions (appear as diaper rash or candida)
  • diarrhea
  • growth failure
  • alopecia (baldness)
  • irritability
  • anorexia
