Healthy Eating Statistics

GITNUXREPORT 2026

Healthy Eating Statistics

Nearly 1.3 billion adults worldwide are insufficiently active, and 42% of adults carry excess body weight, two pressure points that make diet feel more than a personal choice. Pair that with the fact that 23.4% of global deaths in 2017 were tied to low fruit and vegetable intake and you get a stark contrast between what people want to eat and what systems and access make possible.

Healthy eating is not just a personal choice, it is shaped by global pressures that show up in the numbers. About 1.3 billion adults worldwide are insufficiently active, and diet gaps like low fruit and vegetable intake contribute to 23.4% of global deaths. When you line up risks like obesity, food waste, and malnutrition against the efforts to make healthier foods easier to buy, the pattern gets surprisingly clear.
