Getting your child to eat healthfully is a struggle for many parents, especially if you have a picky eater in your family. Picky eaters often bring back unopened lunch boxes or ignore the healthy foods you’ve packed and go straight for the dessert.
The AMDR is 45 to 65 percent of daily calories (203–293 grams for 1,800 daily calories) for carbohydrates. Adolescents require more grain servings than younger children and should eat whole grains, such as wheat, oats, barley, and brown rice. The Institute of Medicine recommends higher intakes of protein for growth in the adolescent population. The AMDR for protein is 10 to 30 percent of daily calories (45–135 grams for 1,800 daily calories), and lean proteins, such as meat, poultry, fish, beans, nuts, and seeds, are excellent ways to meet those nutritional needs.
Children need adequate caloric intake for growth, and it is important not to impose very restrictive diets. However, exceeding caloric requirements regularly can lead to childhood obesity, which has become a major problem in North America. Nearly one in three US children and adolescents are overweight or obese.
For ages nine to thirteen, girls should consume about 1,400 to 2,200 calories per day, and boys should consume 1,600 to 2,600 calories per day.
Adolescents have increased appetites due to increased nutritional requirements . Nutrient needs are greater in adolescence than at any other time in the life cycle, except during pregnancy. The energy requirements for ages fourteen to eighteen are 1,800 to 2,400 calories for girls and 2,000 to 3,200 calories for boys, depending on activity level. The extra energy required for physical development during the teenaged years should be obtained from foods that provide nutrients instead of “empty calories.” Also, teens who participate in sports must make sure to meet their increased energy needs.
Key vitamins needed during puberty include vitamins D, K, and B12. Adequate calcium intake is essential for building bone and preventing osteoporosis later in life. Young females need more iron at the onset of menstruation, while young males need additional iron to develop lean body mass. Almost all of these needs should be met with dietary choices, not supplements; however, iron is an exception, and supplementation my necessary as recommended by the doctor or dietitian.
Teens should be discouraged from eating fast food, which has a high fat and sugar content, or frequenting convenience stores and using vending machines, which typically offer poor nutritional selections. Other challenges that teens may face include obesity and eating disorders. At this life stage, young people still need guidance from parents and other caregivers about nutrition-related matters. It can help explain to young people how healthy eating habits can support activities they enjoy, such as athletics, skateboarding, or dancing.
The first phase involves height increases from 20 to 25 percent. Puberty is second to the prenatal period in terms of rapid growth as the long bones stretch to their final, adult size. Girls grow 2–8 inches taller, while boys grow 4–12 ...
