As someone who buys organic for 99% of all the stuff in our house, it's totally worth it in terms of taste and health. Don't confuse health with healthy. Organic food is not healthier in the sense that it has less calories, less sugar, more nutrition..it's healthier in the sense you don't have a fuck ton of chemicals that you don't need in your body. I'm not an expert, but my gut tells me a lot of the illnesses experienced nowadays stem greatly from all that shit you're fed. At least in certain nations.
Everything you eat has "a fuck ton of chemicals that you don't need in your body." It's called waste. If food didn't have those fuck ton of chemicals, you'd never have to take a shit.
On topic: It's not a scam because the product itself isn't being misrepresented (i.e. something claiming to be grown organically but actually was treated with DDT), and the prices, while higher, reflect increased costs to the producer to user lower-yield techniques.
The study in question shows that the benefits of organic food are a lot narrower than the people selling organic products want you to believe (SHOCKING NEWS: advertisers lie), but that's different from having zero benefit.
So, at that point it's a simple cost-benefit analysis. If the benefits are worth it, buy it. If they're not, don't. Too easy.
TL;DR: Not a scam, but possibly not worth the money.
