Surprising Findings
Solid added sugars showed no link to NAFLD — and may even trend slightly protective (HR 0.96).
Common wisdom says all added sugar is bad, but this study found zero risk from solid sources like desserts or yogurt, contradicting broad anti-sugar messaging.
Practical Takeaways
Swap one sugary drink per day for water, tea, or sparkling water.

Eating ultra-processed foods like sugary snacks and fast food can lead to fat building up in your liver because they're easy to overeat and your body absorbs them too quickly.
If Chinese adults eat a lot of added sugar, they’re more likely to develop fatty liver disease — especially if they’re in the top group of sugar eaters, who have an 18% higher risk than those who eat the least.
Drinking more sugary drinks like soda might raise your risk of fatty liver disease by 20% if you're a Chinese adult, but eating sugar in solid foods doesn't seem to have the same effect — so how sugary stuff is delivered could matter for your liver.
Even if Chinese adults don’t eat a lot of added sugar, the more they consume, the higher their chances of developing fatty liver disease — so even moderate amounts might not be safe for this group.
If Chinese adults eat just 5 more grams of added sugar every day — like a little extra in their drinks or snacks — they may have a slightly higher chance of getting fatty liver disease over time.
