Global Trends

• In 1990, roughly 8.2% of the global population had NAFLD (about 391 million people).

• By 2017, prevalence rose to 10.9%, affecting 882 million people globally - more than double the case count over three decades

Western Trends

• In the United States, NAFLD prevalence increased from approximately 20% in the late 1980s–early 1990s to around 38% today - a nearly 50% rise in just 30 years .

Broader Global Perspective

• More recent reports estimate roughly 24–30% prevalence worldwide, with parallel rises observed in Asia .

• Working-age populations saw a substantial 112% increase in NAFLD cases from 1990 to 2019 - from ~14,478 to ~19,838 per 100,000 population

🔬 What This Means for You

• Fat accumulation in the liver - traditionally rare - has now become a leading metabolic health concern globally.

• The rise reflects escalating obesity, insulin resistance, and consumption of refined sugars (including fructose) - dietary factors closely tied to the topic of our sugar article.

• Addressing sugar intake, blood sugar balance, and stress is not just about waistline - it’s essential for long-term liver and metabolic resilience.
