¶ … Nutrition Food and dietary habits vary from region to region; mostly guided by cultural preferences, access to resources and income levels. It has often found that western countries rarely ever complain of malnutrition problem, while it persists in third world countries. The reason for this is grounded in income levels and access to resources. Most developing countries heavily rely on pulses and beans for calories while most western-nations exhibit a greater taste for meat and poultry. This demonstrates on the one hand, cultural tastes while on the other it also says a great deal about income and poverty. In a report and survey revealed in 1980s, it was found that there existed noticeable differences in per capital supply of calories and protein in different regions of the world (see Table 1). It was observed that developing countries had calories intake 9% lower than the world average. The developed countries on the other hand had 27% higher calorie intake than the world average. The countries that lied below the world average in calorie intake existed in the four regions of Africa, Far Easter, Middle Easter, and Latin America.

However some significant changes have been noticed in food consumption and dietary habits in the last few decades which indicate that with changes in income levels in some developing countries, nutrition levels are also increasing. People with more disposable income in third world countries are spending more on food of their choice thus altering their dietary preferences.
Before the industrial revolution, most world regions exhibited similar food consumption patterns. There were broad similarities in what people ate and the consumption levels were more or less uniform around the globe. Total calorie supply was relatively low since most countries could consume between 1800 and 2300 calories per capita per day (Grigg, 1995). People relied heavily on cereals and potatoes which were seen as good sources of energy supply. Meat was also consumed and it contributed more than 15% of total calorie intake. The dietary patterns in western world were similar to that of the rest of the world. Even developing countries were consuming the same food that European nations were. The reason for this was poverty and cereals and pulses were seen as the cheapest and thus most affordable source of energy.

However these similarities vanished to a large extent in 19th century due to industrial revolution. Agricultural productivity increased because of technological changes and price of food came down resulting in higher consumption of agricultural goods. At the same time, income levels went up and there was a marked improvement in transport that made it possible to transfer goods from one location to another.

These changes led to a dramatic change in food choices in Europe till 1950s. Total calorie intake increased by 50%. Initially European countries increased their intake…
