I have yet to view the video, but it is very true that most Americans eat way too many processed carbohydrates, including sugars, and it has led to our obesity epidemic and and upsurge in chronic diseases. I rarely eat bread or crackers, but when I do, it must have whole grains and nuts in it. Russet potatoes have a very high glycemic index and are often eaten with a lot of fat, especially in the form of french fries. I only eat fingerling potatoes with the peel since most nutrients lie just below the peel, along with the very important fiber. Fiber is one of the most important, but overlooked, nutrients. It feeds our gut microbes and when our gut microbes get out of balance, it can contribute to obesity and other chronic diseases.
