Golden Potato Chowder with Ham &amp; Mushrooms. Don’t Underestimate Spuds: Potatoes have been treated unfairly over the years, but the redskins in this recipe provide about half of this recipe’s vitamin C and potassium – you’ll meet nearly 30% and 33% of your DV of the two nutrients, respectively, in 1 hearty serving. While the well-known immunity vitamin is also necessary for the formation of collagen and the healing of wounds, the mineral potassium may help lower blood pressure.
