Commonly fat and sugar intake are looked at first but going over the RDI for salt is very easy. The USA government recommends a maximum of 6g of salt per day for adults, 5g a day for children aged 7-10 and 3g for children aged 4-6. The amount of salt consumed in one fast food meal is more than twice the daily limit for an adult and four times the daily limit of a six year old.
A family meal from KFC - consisting of eight mini breast fillets, two regular popcorn chicken portions, four regular fries, a large portion of BBQ beans, a large coleslaw and a 1.5 litre Pepsi shared equally between four - could contain 5.2g of salt per person.

Of meal combinations aimed specifically at children, the salt content varied from 4.3g of salt in a Pizza Hut chicken wrap and a soft drink to 0.6g in a McDonald’s Happy Meal of chicken nuggets and a fruit bag.
According to the Cash survey, a family of four sharing a Pizza Hut meal deal - consisting of one Cheesy Bites Meat Feast, one medium Super Supreme, a portion of garlic bread, a portion of potato wedges, chicken wings, and a cheesecake dessert - could eat 12.3g of salt each.
