Why Does 1 Cup of Flaxseed (whole) Vary?
The weight of 1 cup depends on how you measure. USDA standard (spooned) = 149g.
Spooned & Leveled
Spoon the ingredient into the measuring cup, then level off with a straight edge. This is the standard method used by USDA FoodData Central.
Reference weightSifted
Sift the ingredient first, then spoon into the cup. Sifting aerates the ingredient, reducing weight by 10-20%.
~10-20% lighterScooped (packed)
Dip the cup directly into the bag and pack. This is the most inaccurate method — can be 20-30% heavier than spooned.
~20-30% heavierAbout Flaxseed (whole) Density
Whole flaxseeds: 1 cup = 149g. Ground flaxseed (flax meal) is lighter: ~130g/cup. Ground flax is more digestible and bioavailable than whole. 1 tablespoon ground flax + 3 tablespoons water = 1 egg substitute (flax egg). USDA FDC 169414.
Pro tip: For consistent baking results, use a kitchen scale. Weight measurements eliminate the variability of cup measurement entirely. USDA values shown are based on the spooned & leveled method.
