I like this idea because it turns an overwhelming task into a gradual learning process. Instead of trying to understand every label while shopping, you build your knowledge a little at a time.

One important nuance: I'd avoid treating foods as inherently good or bad. A product can be high in sugar but perfectly fine in moderation, while another can look healthy on the packaging but contain surprisingly little fibre or protein. Context and portion sizes matter.

The most useful version of this newsletter would explain why a product is a better everyday choice, compare its ingredients and nutritional values with an alternative, and teach readers one practical thing to look for next time they shop.

Over time, the goal isn't to memorise hundreds of products. It's to become confident enough to evaluate unfamiliar ones yourself.
