Answer 1

1.FIBRE-(D)BULK FORMING.
2.PROTEIN-(C)BODY BUILDING.
3.VITAMINS AND MINERALS-(A)MICRO NUTRIENTS.
4.CARBOHYDRATES-(B)ENERGY GIVING.
Reasons:
1.Dietary fiber, also known as roughage or bulk, includes the parts of plant foods your body can't digest or absorb. Unlike other food components, such as fats, proteins or carbohydrates — which your body breaks down and absorbs — fiber isn't digested by your body. Instead, it passes relatively intact through your stomach, small intestine and colon and out of your body.
2.Whey protein has become a staple supplement for most bodybuilders and other athletes because it's a great protein. Whey has more recently caught on with the anti aging/longevity minded groups also for its effects on immunity.
3.Micronutrients are those nutrients we require in relatively small quantities. They are vitamins and minerals, and our good health requires them in milligram and microgram amounts.
4.Carbohydrates are the body’s chief source of energy for all metabolic functions and anaerobic muscular exertions.  Additionally, carbohydrates are necessary for the digestion and absorption of the other macronutrients.
