Question

Rock Solid
I can not get the meaning of ''Rock Solid '' in this sentence:
''Consumers will start seeing these claims on packages soon, thought some nutritionists and scientists  are worried  that the findings aren't rock solid!''

All I know ''Rock Solid ''  means 'not likely to move or break'

Answer

It's a way of saying 'reliable' in this context.
''Consumers will start seeing these claims on packages soon, ALTHOUGH some nutritionists and scientists are worried that the findings aren't completely reliable or trustworthy".

Answer

Rock solid in this case means that the findings/source are not trustworthy and should not be trusted. Because it may be inaccurate!
