Not sure about the "subconsciously learn" part but you may be concerned to learn that the same "sweet" detectors you have on your tongue are also in your gut, and sign to the pancreas that some glucose is on the way so get cranking.

So I don't drink them out of concern for hyperinsulinemia, insulin resistance in the cells (DMT2) and related endocrine issues.

Please note that there are NO STUDIES of this as far as I know: my choice not to drink them is entirely based on first principles and the easy fact that it's not hard to avoid them. I am not a fan of crazy health fads ("Hey kids, let's wash out those ol' bags of toxins with a juice cleanse") but like I said there's basically no downside to avoiding those drinks anyway.
