THE DOWNSIDE

What to keep in mind

  • Contains 45.1 g carbohydrate but only 2.97 g protein per 100 g, giving it a different macronutrient profile from most nuts.
  • USDA does not report total sugar, fibre, vitamin E, vitamin K or selenium for this record; database zeroes in those fields are technical fallbacks, not measured zero values.
  • Roasting reduces water relative to boiling, so direct per-100-g comparisons can exaggerate differences unless preparation is matched.
  • Chestnut allergy can occur, including in people with latex-related cross-reactivity; seek individual medical advice after a suspected reaction.
  • Whole roasted chestnuts and large pieces can be choking hazards for young children; use an age-appropriate texture.
  • Commercial roasted chestnuts may contain added salt, sugar or flavouring not represented by this plain USDA profile; check the package label.
