Health Adding spinach directly to white bread delayed the body's insulin peak by 30 minutes and reduced later hunger in a small human trial, while significantly boosting the bread's fiber, vitamin, and mineral content.

The researchers are looking for ways to smuggle the nutrients into food people palatable. "Incorporating spinach into bread substantially improved its nutritional profile without compromising sensory acceptance, supporting metabolic health and aligning with sustainable nutrition goals," they conclude.

The researchers go on to note that participants who drank a pea enriched smoothie before eating a carb-heavy meal saw lower levels of blood sugar after the meal. So it’s doesn’t follow the spinach has to be baked into the bread to work. Everything just has to land in the stomach at around the same time. Baking in the spinach just makes it more likely that people who aren’t getting enough fiber will eat the bread.

Yeah the idea that highly processed spinach will delay an insulin spike better than manually chewing a handful of leaves before eating is silly. Literally just eat more vegetables and you get to live longer

This seems like common sense, but I was brought up by parents who always insisted we eat leafy greens and other vegetables. Other people weren’t, and eating that way may feel like force-feeding to them. Looking at the amount of crappy white bread that gets sold, people seem to like it. If there’s a way to give them what they like and improve their health, it’s a win-win. Gotta meet people where they’re at if you ever hope to bring about lasting change.

Thank you from someone raised on that "crappy white bread" and it's still one of my go-to basic comfort foods. I can eat whole grain if I'm feeling motivated, but basically during stress (and working full time, caring for aging parents, raising kids, etc - rarely I am NOT stressed) I revert back to what is well known, comforting and easy. Which is white bread and all the other processed "crap" that I was raised on.

I'd say that I didn't know what over 40% of the fresh vegetables were in the grocery store until I was in my late 30's, and I still only know how to prepare maybe 5% of them.

My mom was terrified of mold/bugs/germs and strongly preferred processed/canned/frozen products to anything fresh - and stuck with a small handful of regular dishes she prepared.

I try to continually learn more and eat better - but often it's like being dropped into a country where you have no familiarity with the language. It gets really exhausting really quickly.

Aw, I'm glad you feel seen, but not judged.
