is it the calcium that probably grasshoppers have plenty of? or is it maybe omega 3s, that I've no idea whether grasshoppers would have!
If we go by calcium then, practically we can get them from numerous sources like bone which has it in abundance.
If we go by the Omega 3s, then we will really require the quantitative animal testing analysis to actually back it up. This for sure are into consideration in further research.
Like your style of thoughts. Always apt with much to think about.
