Yes, that and their Ginger. It's like drinking lemonade with chicory juice squeezed in. That's not "natural tasting", that's just gruesome. I appreciate preferring more natural drinks (especially devoid of that poison HFCS), but my god what were they thinking? Every single person that's come over here has tasted it and they all thought it was something I mixed up as a joke, it's that horrendous.
And yeah, the biggest problem with HFCS is that it's 1) way cheaper to produce and 2) much more addictive. Without resorting to tin foil hattery, it's no secret that the food and drinks industry (especially in the US, where the FDA is in the pocket of all the big f&d producers) purposely manufactures things to keep you addicted. And sugar, and especially HFCS, are extremely so. That's why all fast food has a shitload of sugar mixed in too. It's gross, but I do think that if you know and keep in mind what's going on, you can indulge in some occasional fast food without falling into the trap of becoming addicted.
