Table 1 shows estimated nutrient intake of subjects and the percentage difference between the baseline values and the values in the presence of fruits and vegetables. Reduction was noticed in intake of energy, sodium, fats and related compounds while increased was observed in all other nutrients.

Table 2 shows Body mass index (BMI) and lipid profiles of the subjects. Significant differences (P < 0.05) were noticed between the baseline values and the eighth-week values for all the parameters except the BMI and HDL cholesterol. Also significant differences (P < 0.05) was noticed between the eighth week values and the tenth week values in Triacylgleride total serum cholesterol, however, no significance difference (P > 0.05) was noticed in BMI and HDL cholesterol.
