Are buckwheat noodles healthier than wheat noodles?

For most people wheat grain is fine but some people are allergic or react badly to the gluten content of wheat grain foods. For such people, buckwheat is very useful. It is not really a grain but a pseudo-cereal crop; a fruit seed that is related to rhubarb and sorrel. Therefore it does not have the gluten content that is anathema for some people.
