"Severe food insecurity is one extreme of the scale, but even moderate food insecurity is worrisome. For those who are moderately food insecure, access to food is uncertain. They might have to sacrifice other basic needs, just to be able to eat. When they do eat, it might be whatever is most readily available or cheapest, which might not be the most nutritious food. The rise in obesity and other forms of malnutrition is partly a result of this phenomenon. Highly processed foods that are energy-dense, high in saturated fats, sugars and salt are often cheaper and easier to come by than fresh fruits and vegetables. Eating those foods may mean your daily requirement of calories is met, but you are missing essential nutrients to keep your body healthy and functioning well. In addition, the stress of living with uncertain access to food and going periods without food can lead to physiological changes that can contribute to overweight and obesity. Children facing hunger, food insecurity and undernutrition today may have a higher risk of overweight, obesity and chronic diseases like diabetes later in life. In many countries, undernutrition and obesity coexist and both can be consequences of food insecurity."
