You have a point. These businessman may not understand they need to recommend a proper nutrition. Nobody tells doctors this fact either (which is changing though).
But as I previously stated, only quantity can be argued. Actions speak for companies. And there are many actions, which compel me to belive, some of them are evil. If it means 10% or 30% of the big ones doesn't matter. For small companies, the percent will be lower.
...
By actions I mean just for example denying of correlation of diet and acne, ignoring the trend of natural medicine, which is mainly by food and probably an attempt for making supplements on-prescription, although they are completely safe.
This ignoring may be due to not-knowing or never trying too, but I doubt nobody knows any facts. Progress is too slow.

We need more open-minded people to speed up progress by making science a common knowledge :)
As long as scientific evidence is being utilized to progress, we will be working a maximum efficiency. We are, unfortunately, afflicted with pleas to faith as a society that cause people to reject science for something else they really, truly believe in, which suddenly negates hard facts in front of their face.
Blaming the system by which people are most efficiently able to ensure people who contribute may pursue their own happiness does not progress our global society. Free markets, with their upholding of a non-alienation principle, can be argued as the "moral" economic system.
I very much appreciate your thoughful replies; this depth of exchange with global community members is what I was seeking with my participation on the platform. I have followed and would enjoy discussing more topics with you.
