- I'm Euell Gibbons. I've spent years learning about natural foods. Did you know, goldenrod makes an excellent tea. Natural ingredients are important to me. That's why Post Grape Nuts is part of my breakfast. This wholesome cereal is made from wheat and barley. - These natural ingredients are baked into crunchy nuggets and fortified with vitamins. - It's naturally sweet taste reminds me of wild Hickory nuts. - I call it Grape Nuts my back-to-nature cereal.
