food

In my experience it goes bad days earlier.

The only things which taste better in my experience are heirloom varieties. Most of what's generally sold at grocers has been bred for shipping hardiness instead of flavour. Organic or conventional won't change the variety.

I do food research for a living and have worked in the restaurant industry. Sometimes it does, especially because the varieties that are bred for use with agrochemicals can be a bit "samey", so the combo for an heirloom varietal and organic is almost guaranteed to taste better than a regular alternative.

On the other hand, to me the biggest difference with produce is if it's seasonal. Supermarkets are made to always have the same products regardless of seasonality, so there's an incentive to have fruit and veg that "travels better", but tastes like nothing.

Look up a seasonality chart for your area and follow that for maximum flavor. Plus, seasonal produce is often cheaper because there's more of it.

sometimes

I never noticed much of a difference

I mean, the local produce sucks ass for the most part, so I can't really justify spending extra for no gain

No

A lot of the times the better tasting produce is organic, but its not better tasting because it's organic.

no but the shit you grow fresh yourself is a billion times better. particularly true with things that are better very fresh, typically stuff with somewhat high water content like cucumbers, watermelon, tomatoes, berries, etc.

For whatever reason, I've found bananas to be more pleasant.

hard to tell but yes imo. although sometimes I really miss that glyphosate tang
