Discretionary Calories is not a food group on the USDA Food Pyramid because it refers to the extra calories that can be consumed after meeting all the nutrient needs from the recommended food groups. It includes added sugars, solid fats, and alcohol, which are not considered essential for a healthy diet. The USDA Food Pyramid focuses on promoting the consumption of fruits, vegetables, grains, and other nutrient-rich foods to maintain a balanced diet.

The correct answer is carbohydrates, proteins, fats, minerals, vitamins, and water. These are the essential nutrients that our body needs in order to function properly. Carbohydrates provide energy, proteins are important for growth and repair of tissues, fats are necessary for insulation and protection of organs, minerals are required for various bodily functions, vitamins play a crucial role in metabolism and overall health, and water is essential for hydration and proper functioning of all body systems.

It is important to keep food at safe temperatures because microorganisms can multiply very quickly if food is stored at room temperature. This can lead to foodborne illnesses and spoilage. By keeping food at safe temperatures, such as refrigerating perishable items and cooking food to the appropriate temperature, the growth of harmful bacteria and other microorganisms can be prevented, ensuring the safety and quality of the food.

The correct answer is "All of the above" because the question asks for possible barriers to being physically active, and all three options provided (being too busy, too tired after school or work, and feeling embarrassed to exercise with others) are valid barriers that can prevent someone from engaging in physical activity.

The explanation for the given correct answer is that the Percent Daily Value listed on the Nutrition Fact Label represents the recommended daily value for a nutrient in one serving of food. If a food has more than 20% of the daily value for a certain nutrient, it is considered an excellent or good source of that nutrient. Therefore, the statement is true.

Anorexia Nervosa is a well-known eating disorder characterized by an intense fear of gaining weight and a distorted body image. Individuals with this illness have an extreme desire to be thin, often resulting in severe weight loss and other physical and psychological health issues. Anemia Extremity and Bulbapedia are unrelated terms and do not describe an illness involving a strong desire to be thin.

Dietary fat serves multiple functions in the body. It provides long-lasting energy, helps in feeling full after eating, aids in hormone production, forms part of the brain and nervous system, and is essential for cell membrane formation in every cell of the body. Additionally, it carries vitamins throughout the body, helps regulate body temperature, and provides two essential fatty acids (linoleic acid and linolenic acid) that the body cannot produce on its own. Therefore, the correct answer is "All of the above."

Body Mass Index (BMI) is a number calculated from a child's weight and height. BMI is a reliable indicator of body fatness for most children and teens. BMI does not measure body fat directly, but research has shown that BMI correlates to direct measures of body fat, such as underwater weighing and dual energy x-ray absorptiometry (DXA).1 BMI can be considered an alternative for direct measures of body fat.

Many adolescents need more than 2000 calories as they grow in height, build bones, build muscles and stay active. The 2000-calorie diet is just an estimate and is used to help calculate the Percent (%) Daily Value listed on the food label.

Consuming more water, fruits, vegetables, grains, and calcium-rich foods in balance with proteins provides various benefits. It helps to have energy throughout the day, as these foods provide essential nutrients and hydration. Additionally, it ensures that the body gets the necessary vitamins and minerals for optimal functioning. This balanced diet also helps in staying strong for physical activities like sports, promotes proper growth and development, and helps in maintaining a healthy weight. Moreover, it prevents unhealthy eating habits like skipping meals and feeling excessively hungry, as well as reduces the risk of chronic diseases such as diabetes.

Trans fat is formed when liquid oils are made into solid fats. Trans fats are artificially produced by food manufacturers. They were originally thought to be the healthier option to replace saturated fats. However, research shows that trans fats are not healthier. Trans fats increase LDL ("bad") cholesterol and decrease HDL ("healthy") cholesterol and should be avoided.

Diets RICH in dietary fiber have been shown to have a number of beneficial effects including decreased risk of coronary artery disease.
