As salt is one of the main culprits of this terrible illness, Unimed – Brazil’s largest health insurance company – realised the need to warn people about its use.

On April 26th, more than a thousand people were reached in the engaged restaurants and throughout the day 15,000 others shared videos and photos on social networks.
