I don't think anyone has ever really, seriously believed that white bread was healthy, have they? Or sweet potatoes, just listen to the name of that. Just go back 70 years and you'll find everyone eating plain potatoes and much less sugary cereals than wheat, simply because they were cheaper. Cereals such as Rye and Oat. Don't blame the doctors. No one ever recommended sweet potatoes over real potatoes. People made that choice against the recommendations of their grand parents and figured 'they would be alright'.
