Introduction

Nutrition is an essential component of a healthy and productive life. Across the world, nearly a billion people experience undernutrition, one form of malnutrition. This means they do not consume a sufficient amount of calories, protein, and nutrients to meet their bodies’ basic needs. This can impact physical growth and brain development, as well as the immune system’s ability to fight off disease.

At the same time, more than a billion people in the world consume excess calories that their bodies don’t need. This increases people’s risk of becoming overweight or obese, and developing chronic diseases like diabetes and heart disease. While this problem once primarily affected developed countries like the U.S, it is becoming a growing concern in the developing world as well.
