Final answer:
Dietary protein requires sufficient c) kcalories, particularly from carbohydrates, for efficient use and to support growth. Vegans need diverse plant-based proteins to ensure intake of all essential amino acids. Essential fatty acids and fats in the diet aid in vitamin absorption and hormone production.
Step-by-step explanation:
Dietary protein will not be used efficiently and will not support growth if kcalories (especially from carbohydrates) are lacking in the diet. It's important to consume carbohydrates because they are the primary source of energy for the body. They supply the energy necessary for daily activities and are essential especially when dietary protein is to be used effectively for growth and repair. In the absence of sufficient carbohydrates, proteins are utilized for energy, which doesn't allow them to perform their primary roles such as repairing tissues and supporting growth. Vegans need to pay special attention to the protein they eat because it is more difficult to obtain all essential amino acids from single plant sources. Essential amino acids are those that the body cannot produce on its own and must be obtained through diet. Plant proteins often lack one or more of these essential amino acids, making it important for vegans to consume a variety of plant-based proteins to ensure they get all the necessary amino acids. For fat-soluble vitamins and hormone production, essential fatty acids and fats are necessary components of a healthy diet. They help in the absorption of vitamins and contribute to satiety, thereby preventing overeating and promoting weight management.
