Fresh veggies & fruits, a little quality meat (but not too much and not every day), no industrial bread (I live in Paris, we still have access to a few real artisanal bakeries where they make their own bread, but here too they’re getting replaced by industrial ones, so we’ve planned on learning to make our own bread soon), no industrial sweets/treats and no soda.

My spouse and I also learned to cook, instead of going out to a restaurant multiple times a week like we used. Saves us money and it’s a fine moment we spend together too ;)

As for the time it takes to cook fresh food: either we will make very simple meal, which takes minutes (plus we often have fun while cooking) or we will cook a meal that we will last us 2 or 3 days. So it’s really not that much of an issue. And since eating better helps us feeling a lot less tired too, well… we think it’s really worth it. The real effort is to be willing to change one’s own habits, at least if I can relate to my own experience.

Edit: maybe I should make it clear that the key change, and the very first step anyone should do is to stop eating those ready-made, over-processed and over-packaged shit food that we’ve learned to consider normal food. Sorry I this sound rude, even more so in the USA I would imagine, but this what I think they’re worth (with all their sugar and salt, and conservatives and colorants) and how good I think they’re for our health: barely a few weeks after I quite eating that I started getting better. To me, it’s the same shit as the cigarettes and if we don’t self-destroy in a nuclear holocaust (or ins ome ecological major crisis) before that I have little doubt this industrial food will end being an even worse scandal than tobacco ever was.
