Question

a) It is observed that constipation is common among people in western countries who eat more meat and processed food than us. What can be the reason for this?
b) Incidence of goiter among the people living in the Himalayan region was quite high. Why

Answer 1

a) The reason is meat and processed food contain very little roughage or fibre and lack of it leads to constipation. As people in western countries mostly depend on processed foods and bread etc they experience constipation

b) The incidence of goitre among the people living in the Himalayan region was quite high. A lot of snow is experienced in Himalayas which leads to the leaching of iodine from the soil. The crops grown in a soil which is iodine deficient will lead to people consuming food with low dietary intake of iodine.
