Processed food is problematic because it is high in sugar and low in fiber, whereas a low sugar, high fiber diet, termed 'real food', is beneficial.

“what you want is a low sugar high fiber diet that's called real food”

“processed food has several things wrong with it sugar being one of them but lack of fiber being another and I think that that is equally important”

“every diet that works is real food and every diet that doesn't is because it's processed food”

“What we say is processed food is the problem because processed food is high sugar, low fiber. What you want is a low sugar, high fiber diet. That's called real food.”
