New ad banner saying never eat bananas? unhealthy much

That's a stupid ad to have on a healthy eating website when doctors tell you to eat a banana as a good source of potassium and slow burn cals etc so why it there suddenly all these ads around the edges telling me not to eat them and 'drop 3 dress sizes learn the shocking truth'. Shouldn't MFP choose what ads they allow? I know it's for profit to keep it going but surely there should be only healthy ads or ads with nothing to do with dieting or food?
