(a) Calcium is mineral needed in the body to make bones and teeth stronger.
(b) There are two broad types of nutrients; they are micronutrients and macronutrients. Micronutrents are those nutrients that the body needs in little amount/quantity (examples are vitamins and minerals) while macronutrients are nutrients that the body requires in large quantity (examples are carbohydrates, proteins, and lipids)
(c) Iron is a mineral that assists in blood production in the body.
(d) Oil and butter are good sources of lipids in the body.
(e) More water/glucose is required for people who do a lot of physical work. Water helps transport nutrients around the body which helps to produce energy (that is needed after an exercise); an individual exercising loses water through sweat and will need to gain this water back by drinking. While glucose break-down leads to the production of energy. This is the reason water or glucose is needed more by an individual who do a lot more physical work.
