Explain about the Protein-Energy Ratio (NDP Cal%)?

Platt and his colleagues (1961) are largely responsible for the introduction of the ratio of protein energy to total energy (PE ratio) as a us.efu1 measure of dietary quality in human nutrition. To take into account both the quality and concentration of the protein, they introduced the concept of the net dietary protein calories as a percentage of total calories (NDP Cal%). The NDP Cal%, is the net dietary protein value expressed as percent of total calories. The NPU or the chemical score could be utilized in calculating the NDP Cal% as both of them are indicative of protein value. The formula used is as under:

For adults, diet with an NDP Cal% of 5% would be adequate to maintain health. In infants, children, adolescent and pregnant women, growth is supported only by a diet providing an NDP Cal% of 8% or above.
