Restrictions on advertising of food and drinks that are high in fat, sugar and salt to children will take effect from January next year, to curb childhood obesity.

And to protect youth, a ban on shops from displaying cigarettes will be in place by the end of next year, said Parliamentary Secretary for Health Muhammad Faishal Ibrahim on Wednesday.

His ministry later said nutrient criteria are being developed to decide which food and beverage products can be advertised to children.

The guidelines will be incorporated into the Singapore Code of Advertising Practice.

As for the ban on displaying cigarettes, retailers will get 12 months' grace after the law is gazetted.
