Ingredients

Ingredient Amount Grams
Popcorn, air-popped, unsalted 6 cups air-popped popcorn (about ¼ cup kernels) 48 g
Butter, unsalted 1 tbsp unsalted butter, melted 14 g
Sugar, granulated 2 tsp sugar 8.4 g
Cinnamon, ground ½ tsp ground cinnamon 1.3 g

Steps

  2. Mix the sugar and cinnamon.
  3. Drizzle the butter over the popcorn, toss, then sprinkle the cinnamon sugar and toss again.

Why it works for kidneys

  • Salted microwave popcorn has about 300 mg sodium in 3 cups; this has under 5 mg.
  • Popcorn is a whole grain, but it is lower in phosphorus than nuts or seeds: about 86 mg in 3 cups.

Make it fit you

  • Savoury: skip the sugar and use garlic powder and black pepper, or a salt-free herb blend without potassium chloride.
  • Less carbohydrate: use sucralose in place of the sugar.
