text: It may help if you clarify your question... Here are some ideas, hope they help:\n1) Balanced diets: The human body requires food for nutrients, which provide energy and replace molecules used in bodily processes in order to function properly. Good health requires moderation and a balanced diet consisting of nutrients taken from all of the six main food groups - carbohydrates, lipids, proteins, vitamins, minerals and water. Suggest possible sources of these e.g. carbohydrates are from cereals, lipids and proteins can be obtained from nuts etc. The amount of component required depends on one's age, gender, weight, occupation and amount of physical activity --- elaborate.\n\n2) Digestion is needed to break down large insoluble polymers into smaller, soluble monomers so that they can be absorbed. They also need to be broken down into a suitable form so that they can be assimilated (become a part of the tissues of the body). Digestion therefore releases nutrients, which can provide energy, especially carbohydrates (main energy source), lipids (most concentrated energy source), and proteins (to some extent, from deamination).\n\nGood luck!
