When we hear the word "malnutrition," most of us think about starving people or nutrient deficiencies caused by extreme poverty. But there’s another side to this: malnutrition doesn’t just mean not eating enough—it also means eating the wrong things in excess. In fact, over 1.9 billion adults worldwide are overweight or obese—more than four times the number of undernourished people!

In today’s world, especially in high-income countries (and increasingly in middle- and low-income countries too), we’re eating ourselves into diseases like heart disease and type 2 diabetes. That’s the other side of malnutrition—eating poor-quality food that leads to illness and early death.

When we talk about what kills us, diseases like heart disease, cancer, and stroke often top the list. But here's the kicker—many of these deaths are directly linked to poor nutrition. Look at the stats:

What’s shocking is that up to 90% of heart disease and 50% of strokes could be prevented with better nutrition. Malnutrition, in the form of excess and poor-quality food, is quietly the #1 cause of death in the U.S. The worst part? It’s not even labeled that way.

Even deaths that seem unrelated to food, like drug overdoses or suicides, are connected. Our physical and mental health are tightly intertwined, and the despair caused by illness, financial stress, and ineffective treatments can push people to extremes. Poor nutrition plays a huge role in this cycle of decline.
