US nutrition and energy bar retail sales

America has spent eighteen years simultaneously deciding that both its people and its dogs deserve better snacks. As protein bars multiplied in flavors, formats, and dubious health claims, the dog treat aisle expanded to match — freeze-dried liver, grain-free jerky, dental chews with more ingredient transparency than most human foods. The correlation of 0.9721 is perhaps the most logical one on this entire website.

Both markets are expressions of the same 'humanization' trend in consumer spending. From 2005 onward, wellness spending expanded dramatically across both human and pet categories, driven by rising disposable income, health consciousness, and the growing tendency to treat pets as family members deserving premium nutrition. The same demographic — urban, millennial, health-conscious — drives both markets.

The most honest thing this correlation reveals is not a statistical quirk but a cultural portrait: a generation that extended its anxious relationship with food to every creature in its household.
