Bravo @Rainer - you are an inspiration.
Only a few years ago I had an “aha! moment” while browsing in the supermarket (or maybe it was more of an OMG! moment). It was like the scene in The Matrix when Neo can finally see it. All saw in the supermarket was sugar & highly processed foods in most of the aisles. When you take all those products away you are left with very little in a supermarket. It is amazing how obvious the revelation was but we do not see it.
I live in Spain, the Mediterranean diet is almost becoming mythical these days. I’m also taking the same approach as yourself - avoid highly processed foods & cook more at home with fresh ingredients.
More people should try and grow foods at home but it is difficult if you live in a city in a flat. But as the saying goes - baby steps.
How do you feel after a month reducing your sugar intake?
