How this is worked out

  1. USDA measures every nutrient per 100 g of edible portion. That row is published here unchanged — nothing is rounded up, smoothed or "adjusted".
  2. The energy figure is USDA's own, derived with food-specific factors. This site never computes the calorie count it publishes.
  3. The Atwater shorthand 4 · 4 · 9 is applied to the protein, carbohydrate and fat grams only to split that energy into shares — and where the shorthand disagrees with the published figure, the gap is printed rather than hidden.
  4. A serving is a straight proportional conversion of the per-100 g row, using USDA's own household measures for the grams.
  5. The walking figure uses MET 4.0 at 70 kg, the same equation the sister site publishes.
per serving   = per 100 g × serving grams ÷ 100
energy shares = 4·P + 4·C + 9·F      (P, C, F in grams)
walk minutes  = kcal ÷ (4.0 × 3.5 × 70 ÷ 200)
