You can safeguard the nutrients in your mashed potatoes by cooking them a little differently this year.
The trick? Boil them whole. The reason? Cubing your potatoes first will slash their potassium content by as much as 50 percent.
Potassium and More
Okay, boiling them whole does take a bit longer. But the payoff is that you get not only more potassium but more of other important minerals, too: magnesium, manganese, phosphorus, iron, and zinc. (Roasting, baking, or microwaving whole potatoes also preserves more potassium, by the way.) Here are some other cooking tricks that can help you max out your food’s nutrition.
