This is what being experienced in India in recent years consistent with the Bennet’s Law which suggests that as incomes increase, the proportion of starchy staples in the food basket declines relative to the share of more expensive sources of calories.

Data on expenditure pattern in both rural and urban areas suggest that the shares of expenditure on protein food in total expenditure have increased.
