Any wheat and any potatoes according to people like Gary Taubes. Sweet potatoes are probably better than regular spuds. Wheat and potatoes are mostly just carbohydrates which, as explained in the video we're discussing, should be reduced. There's no such thing as an 'essential carbohydrate' and all other vitamins and minerals in potatoes and wheat can also be found in more than sufficient quantities in 'good' foods like meat and leafy veggies.
This is where I find Dr. Ludwig's work interesting. My understanding is that you can't just look at nutrients individually. For example, a carbohydrate eaten in a highly processed form is digested, substantially different, at a chemical level, than carbohydrates eaten with fiber.
I don't doubt that carbohydrate consumption has gone up and with it, suspiciously, so too has obesity. But I can't help but think we should be looking at the package containing these newly consumed carbohydrates.
A mars bars contains 40g of carbohydrate...are people grouping that with 40g of carbohydrates yielded by potatoes and wheat?
