Salt Warnings on Menus Reduce Consumer Salt Intake, Study Finds
Imagine your food has a warning sign if it's too salty, like a red triangle.
A study in the UK found that these warnings on restaurant menus and food labels help people eat less salt.
When people saw the warnings, they chose foods with less salt.
Different shapes of warnings worked, but the red octagon was most effective.
The World Health Organization says we should eat very little salt because too much can make us sick.
They suggest using less salt and maybe special salt that has less sodium.
UK study showed salt warning labels effectively reduced salt intake.
Four different warning labels tested; all resulted in less salty food choices.
Red octagon labels led to the fewest selections of items with warnings.
Average reduction in salt consumption was 7.4% per restaurant meal.
WHO recommends less than 2g sodium daily; excess linked to health risks.
