Carbohydrates are hydrolyzed in the body to yield glucose which can be utilized immediately, or stored as glycogen in the muscles and liver. Proteins are important in the body for the production of hormones, enzymes and blood plasma. They are immune boosters and can help in cell division well as growth
(Okeke et al., 2008).
Fats are secondary plant products that yield more energy per gram than carbohydrates. Dietary fats are important not only because of their high energy value but the fat-soluble vitamins and essential fatty acids of natural foods. Fats and oils help to regulate blood by pressure and play useful role in the synthesis and repair of vital cell parts
(Ilodibia et al., 2015).
