A two-season diet assessment was done on 1957 urban and 758 rural subjects as part of air pollution, health survey. Only 46% rural and 48-55% urban subjects showed adequate calorie intake daily. Protein intake was low (below 30 gm. daily) in 46% rural and 11-19% urban subjects. Rural diets were quantitatively and qualitatively poorer. A major factor in poor nutrition was family income. In children of 0-4 age group, 57% rural and 21-37% urban subjects had inadequate calorie intake. The proportions in older subjects were lower. Detailed food consumption values from Bombay and villages around have been reported. Particularly poor intake of vegetables and pulses were revealed. There was significantly in higher prevalence of all respiratory complaints with lower caloric nutrition in residents from highly polluted area (P<0.05). This relation was also evident in the residents of 'low' area for multiple lower respiratory symptoms (P<0.05). Nutrition and income may have significant role in enhancing respiratory morbidity in relation pollution.
