Florent Lefortier answered Yes, bread does contain potassium – it’s found in the flour. There’s around 100mg of potassium per 100g of white bread, and 248mg per 100g of wholemeal bread. Although bread contains potassium, it isn’t the best thing to eat if you’re looking to increase your intake. If you want high-potassium food, try some of the following:Bananas – 358mg of potassium per 100gPotatoes – 421mg per 100gSeafood –Up to 636mg per 100gCocoa powder – Up to 1.5g per 100gDried apricots – 1.9g of potassium per 100gPumpkin seeds – 919mg potassium per 100gSoy products – 445mg per 100g of soy protein All these foods are great sources of other nutrients, too, and they’re much better for you than bread. Bread's still nice to have occasionally, though! It's a good source of carbohydrate, a great comfort food, and it’s been a staple food in most cultures for centuries.
