Mr. Age is AgeGen's editorial character. Facts come from the protocol above.

Ingredients (1 serving)

  • Steel-cut oats, dry — 40 g
  • Milk, 2% — 240 ml
  • Apple, diced — 1 medium (180 g)
  • Walnuts, chopped — 20 g
  • Ground cinnamon — 1 tsp

Macros per serving

  • Calories: 520 kcal
  • Protein: 16 g
  • Fat: 21 g
  • Carbs: 67 g
  • Fiber: 10 g

Key micronutrients

  • Fiber — ~10 g
  • Magnesium — ~110 mg
  • Calcium — ~300 mg

Why it earns a spot in the rotation

  • Steel-cut oats are a whole grain eaten largely intact, which is the form the Harvard T.H. Chan nutrition source points to for the fibre and metabolic benefits of whole grains.
  • 10 g of fibre from two whole-food sources — the oats and the apple — rather than an added fibre ingredient.
  • ~110 mg of magnesium and ~300 mg of calcium from the milk and walnuts, both minerals many adults fall short on.
  • A hot, slow-simmered breakfast that holds its texture better than instant oats, with no added sugar needed beyond the fruit and cinnamon.
