Avalrable data suggestthat people tend to select protein intakes that contrlbute I-0 to 12 per cent oftotal dietary energy, so that in general, if calorie intake falls belo!, therequlrement level, a person will also be Busceptible to protein ateficlency.Therefore lt is likely that the figures of table 42 corregpond fairly closely tothe numbers of those rrho are also protein malnourlshed, although there arecerlainry instances of protein deficiency among people t{ith average carorie lntakeabove the critical lirnit of 1.2 B!4R. 258.

analysis: The text discusses the issue of undernourishment and its projections for the year 2000. It highlights the percentage of people with calorie intake below the critical minimum limit and the estimated numbers of undernourished people in different country groups. The text also mentions the importance of agricultural growth and its impact on reducing the number of undernourished people.
