if you have digestive issues than some of that article may apply, but for people with a healthy gut it's mostly hooey. people have been eating stir-fries, soups and stews for many, many thousands of years. nobody worried about not eating tubers or rice at the same time as the meat.
continue to work on your gut health and maybe seek out bread not made from wheat if you must have toast.
btw, any article talking about "live enzymes" in your food? red flag for woo. once harvested your vegetables and fruits are no longer "alive".
As I ate the oysters with their strong taste of the sea and their faint metallic taste that the cold white wine washed away, leaving only the sea taste and the succulent texture, and as I drank their cold liquid from each shell and washed it down with the crisp taste of the wine, I lost the empty feeling and began to be happy and to make plans.
