ABSTRACT

Most of nutrient requirements can be met by increasing the consumption of fruits and vegetables to 5-13 servings/day. In addition to meeting nutrient intake levels, greater consumption of fruits and vegetables is associated with reduced risk of cardiovascular disease, stroke, and cancers of the mouth, pharynx, esophagus, lungs, stomach, and colon. The proximate composition and mineral constituents of Chlorophytum comocum root tubers were evaluated. The root tubers contained a ashes: 10.38%, crude protein: 4.54%, crude lipid: 2.00%, crude fiber: 17.24%, and carbohydrates: 65.84%. The leaves and stem also have high energy value (299.52kcal/100g) dry weight. Mineral ranges (mg/100g dry weight, DW) were: K (4.29), Na (3.95), Ca (13.14), Fe (1.89), and Zn (0.76). Comparing the root tubers mineral contents with recommended dietary allowances (RDA), the results indicated that Chlorophytum comocum root tubers could be a good supplement for some nutrients such as calcium, fibre and carbohydrates. The root tubers could be promoted as a carbohydrate supplement for cereal-based diets in poor rural communities. One discussed drawback to the use of vegetables in human nutrition is their high fibre content, which may cause intestinal irritation and a decrease of nutrient bioavailability.
