The world has moved away from carbs over the past 40 years toward diets higher in animal-based foods, reports the United Nations Food and Agricultural Organization (FAO). FAO says the move toward consumption of more animal protein, vegetable oils and sugar, particularly in developing countries, is partly due to easier transfer of production and processing technologies, economic development and changing lifestyles.

“Robust economic growth in developing countries has resulted in real GDP [gross domestic product] gains of more than 3% annually over the past few decades,” FAO said.
