Historically, diets rich in plant foods declined with prosperity in Western nations. Despite known health benefits, low fruit and vegetable intake persists, especially among poorer populations, with little prospect of improvement.

Area of Science:

  • Nutritional Science
  • Public Health
  • Epidemiology

Background:

  • Historically, Western diets were plant-based until the 19th century.
  • Urbanization and increased prosperity led to reduced intake of some plant foods and increased animal food consumption in Western populations.
  • Current dietary patterns in many developing nations resemble historical Western diets, with rural populations having restricted food choices.

Purpose of the Study:

  • To analyze trends in fruit and vegetable consumption across different populations.
  • To highlight the disparity in plant food intake between Western and Mediterranean countries, and within Southern Africa.
  • To underscore the public health implications of low fruit and vegetable consumption given their protective role against chronic diseases.

Main Methods:

  • Comparative analysis of historical and contemporary dietary patterns in Western and developing populations.
  • Examination of national food consumption data, including variations based on socioeconomic status and geographic region.
  • Review of dietary guidelines and their impact on fruit and vegetable intake.

Main Results:

  • Western populations show a significant decline in potato intake, with only modest increases in vegetable and fruit consumption.
  • Mediterranean countries exhibit substantially higher fruit and vegetable consumption compared to the UK and USA.
  • In Southern African cities, low fruit and vegetable intake is linked to cost, affecting both white and Black populations.

Conclusions:

  • Low consumption of fruits and vegetables, particularly among lower socioeconomic groups, is a significant public health concern.
  • The protective effects of fruits and vegetables against coronary heart disease and cancer are well-documented.
  • Despite recommendations, a rise in fruit and vegetable intake, especially for disadvantaged populations, appears unlikely in the near future.
