Food contains carbohydrates (bread, cereal, rice, pasta, potatoes), protein (meat, poultry, fish, dry beans, eggs, nuts, milk, cheese), lipids (fats, oils), vitamins, minerals and water. All six of these nutrient groups are found in foods in varying amounts.A healthy diet may supply all the essential nutrients and calories for typical growth and development during childhood. At least half of all calories consumed should come from carbohydrates. High carbohydrate food produces fuel and provide energy for the brain.
Carbohydrates can be stored in the muscles and released as needed for energy. Protein should be 10 to 15% of the total calories consumed. Protein provides amino acids which help with new tissue, hormones, enzymes, and antibodies. It also proceeds nitrogen, which helps to keep tissue healthy.Generally speaking, animal protein is higher in essential amino acids then plant protein. A lack of protein in the diet, especially during infancy, can lead to a reduction in growth rate and muscle depletion. Lipids (or fats) are another important source of energy.
They are also involved in the maintenance and well being of membranes, hormones and cellular signals. Fats produce energy, give food its taste, and make us feel full. Fats are also what generally cause us to gain weight, have cholesterol problems, and can cause blockage in the arteries. Infants require a higher percentage of fat calories then older children.
