If you're down with eating disgusting things and only interested in nutritional value why bother with insects and not skip directly down to algae/bacteria - my guess is since these are simple organisms they can be genetically engineered for mass production with low maintenance and "tweaked" for desired nutritional values. Risks of disease sound much lower too.
