A survey by the Food Commission says processed food is saltier than ever before.
Crisps have double the amount of salt than in 1978.
And foods like Dairylea Lunchables and Burger King kids' meals have more salt in one serving than a six-year-old should have in a whole day.
And David Beckham, Michael Owen and Gary Lineker have all been criticised for their ads for snacks and fizzy drinks.
The Food Commission report says they shouldn't advertise unhealthy food because children look up to sports stars.
