Health wellness and nutrition are getting quantified like never before, and the latest figures make the stakes hard to ignore. Among adults, 1.9 billion are overweight and 650 million are obese, while 11.7% of adults have diabetes and 30% are physically inactive, all alongside a growing wellness economy that ranges from functional food ingredients to virtual care. But the same dataset also captures surprising gaps and behavioral shifts, from who is using health apps to how many people still lack safe drinking water, and that contrast is exactly where this industry’s real direction becomes visible.
