Yes, anything. You can eat anything and live a healthy, fit life.
Humans all over the globe (ie, nations with highest longevity) live long, non-disease ridden, healthy lives eating a wide variety of foods which even include: noodles, rice, sweet potatoes, potatoes, cheese, bread and legumes.
Bwwwaaat?! Bread and rice?!!!
As fast as you can, ditch a hyper-focus on consulting diets for “what should I eat?”…other than providing a label, those diets create an illusion, a superstition, and distract from the real, powerful variables in play.
Obviously, really, eat anything (as long as it’s real food in close to real form, in really small quantities, from really local sources, prepared by real humans)…so that’s done…off the table.
Then, it’s highly more likely and more worth our mental energy to consider the important variables from high-longevity, healthy cultures; things we can learn:
Eat foods that have not been modified or exposed to chemicals.
Drink clean water.
Breathe clean air.
Spend time outside .
Minimize exposure to toxins, endocrine disruptors, etc.
Minimize exposure to stress (esp. stressing over what to eat!)
Make movement a normal part of daily experience.
Engage in meaningful social relationships.
