Nutrition-related concerns for adolescents include the over-consumption of sugar-sweetened beverages, such as fruit drinks, sport drinks, low-calorie drinks, and other beverages that contain added sugars.
Among adolescents, iron-deficiency anemia, which occurs when your body doesn't have enough iron, is one of the most common diet-related deficiency diseases. This is due to their increased blood volume and muscle mass during growth and development, such as the large increase of lean body mass in adolescent boys, increased body weight, and the beginning of menstruation for girls. All these factors should be taken into account when assessing iron needs in teens.
Inadequate calcium intake is another nutrition-related concern for adolescents. Your skeleton accounts for at least 99% of your body's calcium stores and the gain in skeletal weight is most rapid during the adolescent growth spurt. Almost 50% of adult skeletal mass is formed during early adolescence, between 10 and 14 years in girls and 12 and 16 years in boys. All the calcium for the growth of the skeleton must come from the food that teens eat. So, it is important that their diet supplies a sufficient amount of calcium to help build the strongest bones possible, which is crucial for reducing the risk of osteoporosis later on in life.
Unsafe weight-loss methods and eating disorders are also nutrition-related concerns for adolescents. Being overweight or obese is a major concern for children and teens, and it is generally caused by poor eating habits and a lack of physical activity, or a combination of the two.
Dietary Recommendations for Adolescents
Nutrient requirements for both males and females increase significantly during adolescence. Prior to puberty, nutrient needs are somewhat similar for boys and girls. It is during puberty that physical and biological changes occur that affect gender-specific nutrient needs. Teens' dietary needs are based on gender, age, and activity level. Generally, teenage girls need anywhere from 1,600 to 2,400 calories per day, while teenage boys range from 1,800 to 3,200 calories per day.
Adolescents need the same nutrients as younger children and adults. They should consume 50 to 60% carbohydrates, 45 to 60 grams of protein, and no more than 30% of dietary fat each day. In addition, a balanced diet consisting of foods from the five food groups should supply all the vitamins and minerals teens need.
Daily Dietary Recommendations for Adolescents:
- Vegetables - three cups
- Fruits - two cups
- Grains - six ounces
- Meats & beans - five to six ounces
- Dairy - three cups
- Oils - five to six teaspoons
- Fats & sweets - limit as much as possible
Calcium intake, on average, is about 200mg/day for girls and 300 mg/day for boys. Consuming several servings of dairy products, such as milk, yogurt, and cheese, will help ensure that the recommended calcium intake can be reached. A diet composed of iron-rich foods, like meats and fish, as well as beans, dark green vegetables, nuts, grains, and iron-fortified cereals, will ensure that teens are getting enough iron in their daily diet.
Lesson Summary
In summary, nutrient needs are greater during adolescence than any other time in the lifecycle. Teens will experience several growth spurts, so failure to consume an adequate diet at this time can result in delayed physical, hormonal, intellectual, and emotional development and growth. Nutrition is also important during this time to help prevent adult diet-related chronic diseases, such as cardiovascular disease, cancer, diabetes, and osteoporosis. Some nutrition-related concerns for adolescents include over-consumption of sugar-sweetened beverages, iron-deficiency anemia, inadequate calcium intake, unsafe weight-loss methods, and being overweight or obese.
