Or stop worrying about labels by only eating things without labels.

Probably because I'm not American or a native English speaker, I don't get what you mean by labels in this context.

At least in US grocery stores, there is an inverse relationship between the prettiness of the packaging, and the healthfulness of the product. Fresh produce and such aren't packaged at all.

I think he might be referring to the existence of labels on food products. Some countries might not have labels listing ingredients on processed food products.

In the US, all packaged foods required labels with nutritional info. OP describes how those labels are purposefully misleading. I'm suggesting eating fresh produce and never worrying about labels again.
