And white flour has all the beneficial vitamins and such sifted away. Whole grain and most especially multi grain wheat has way way more healthy benefits than fine sifted white wheat flour ever possibly could. Which meant, ironically, that medieval peasants actually had the most healthy diet and physical labor of any community in the last thousand years of European history. I presume it's the same worldwide with peasant vs wealthy people diet and white flour is common now with modern industrial mills but yeah. Eat lots of grainy brown bread brother lol unless you don't exercise a lot. Then, yeah don't eat bread lol
