Nope - it's a great reason to not even start spreading more bullshit into the info-sphere.
(The same can be said for almost everything related to nutritional "science".)
If we don't have a good mechanism for knowing something is true or not, we should acknowledge that and approach the problem philosophically / aesthetically.
We need to know what we know so that we can use knowledge as our building blocks, not fake information.
You can't magic science into existence and then use it to make decisions.
