So much of the debate is framed on the basis of emotionally-laden buzzwords or terms that have no true descriptive value, that it makes me tend to believe it's about belief more than science. It's a religion, folks.
Natural versus artificial. What's natural, exactly? What's artificial? I hear terms like 'processed' and 'manufactured' to mean 'artificial', but truthfully, that doesn't mean much, or it means what you want it to mean. And the assumption is that 'natural' means good and 'artificial' means bad. I see some evidence of some positive effects from so-called natural foods, and some negative affects from so-called artificial foods, but not enough to make blanket condemnations or recommendations. Organic poisons are natural; I'm not going to eat them. Lab-grown meat, if it comes to commercial use (and it's starting to look possible) is most definitely artificial and I'll eat that with no problems.
Terms like 'big pharma'. Yes, I get it, big companies make drugs intended to fix specific problems, and they have a huge vested interest in getting them sold. There are also quite a few drugs sold that are made by 'big pharma' that simply save lives, and have no 'natural' counterpart. Sure, there are people who believe that 'big pharma' just wants to kill people, and there are 'natural' alternatives for every drug that are just as effective. They're wrong. That's religion, not science, and deep down, they know it. It's politics, it's religion, but it's not science. I get that you hate big pharma. I don't care. It's colored your logic, and that makes you dangerously wrong.
Drugs versus supplements. Drugs are bad. Supplements are good. What rubbish. The two terms seem to mean, in use, that if big pharma makes it, it's a drug. If a fly-by-night crap-merchant puts an 'all natural' label on it and sells it on late-night TV, it's a supplement. The Metformin I take for my diabetes? It's synthesized now, but it was a 'natural' cure originally, extracted from Lilac flowers. Ooh, big pharma using a natural cure. They're so evil. It's so bad for me. Now that it's synthesized instead of extracted from the actual flowers, it's no longer the same chemical, so it's bad bad bad. Uh, no. Wrong.
The very words used to frame the debate makes it clear to me that there isn't much science involved; just religion and politics.
Something being a drug doesn't make it bad. Being a supplement doesn't make it good. The reverse is also true, of course. But we can't get to that point, because the supplement-supporters won't subject their pet drugs, oops, I mean supplements to rigorous scientific testing by independent testing facilities. They claim efficacy they can't prove. Do they work? Maybe. I'm sure in some cases, they do. But frankly, I'm not shoving a bunch of pills down my throat because 'maybe' they work.
