Reasons for increasing food consumption

Food consumption has been rising globally for over 50 years. (HICs) consume the most calories, but (LICs) are experiencing the biggest increase in calorie intake. There are two main reasons for increasing food consumption:

  1. Economic development. As countries become wealthier, people can afford to eat more food. People in Chad and Somalia eat less than 2,850 calories a day, whereas those in the USA and Italy consume more than 3,440 calories a day. Many HICs have high levels of because people buy more food than they need. Fast food and food advertising also increase food consumption in wealthier places.
  2. Rising population. World population continues to grow and is likely to exceed 8.5 billion people by 2030. This means there are more mouths to feed. The most rapid growth is taking place in LICs and some (NEEs), like China and India.

Measuring hunger

The (GHI) is calculated by the International Food Policy Research Institute (IFPRI). It measures world hunger. Each country is given a score between 0, which is no hunger, to 100, which is when everyone is hungry. Three things are used to calculate this score:

  • - the percentage of people consuming too few calories
  • number of children underweight - the number of children below the age of five who are underweight
  • - the death rate of children below the age of five

The Global Hunger Index is used to target initiatives.

The areas where the greatest percentage of the population are undernourished (greater than 25%) are concentrated in Africa and Asia.
