yes, well you're wrong. There is both a science degree and an arts degree obtainable on business administration/management. The difference is a few prerequisites. The application of such, as well as the depth of study, has an impact on whether they are a researcher or a technician. But neither can be logically argued to be scientists.
Even a degree in a pure science doesn't make someone a scientist. There are a multitude of degrees with the "science" label, but that does not make scientists out of the obtainers of such degrees, it only provides them an educational background that is clearly higher than yours, ya njub.
My very close friend has a masters degree in library science and works as a research analyst. If you were to call him a scientist, he would laugh you out the door. I have a relative who is a registered nurse. She has comparable education to the nutritionist in contention, but she would also laugh you out the door if you were to call her a scientist.
Give it up. You are raging on about this person allegedly being a scientist, but what really matters, and what you are constantly attempting to avoid, is the fact the article you presented is not a peer-reviewed study and is, instead, an op-ed (an opinion piece posed in a Men's Health magazine). It is devoid of attribution and dismissive of existing peer-reviewed studies. Even ignoring all the glaring "wrongness," I already indicated the author's schill status for being a paid sponsor to dairy products (whey protein, casein, etc). That cuts right into his credibility.
Geez Jakkals, you seem to have gone out of your way to completely ignore the peer-reviewed studies previously provided, and are instead jumping up and down about this opinion article as if it were gospel. Don't you see how ludicrous that looks?
