Raw flaxseeds have 27.3 g fiber and 42.2 g fat per 100 g. Ground flax releases nutrients that whole seeds cannot — whole flaxseeds pass through the gut largely undigested. A typical tablespoon (10 g) adds 53 kcal. Store ground flax refrigerated as the exposed oils oxidize quickly.
How should I track Flaxseeds?
Flaxseeds is high in fiber. Nuts like Flaxseeds are one of the easiest foods to overeat. Research on portion estimation (Almiron-Roig et al., Appetite 2013) found that people underestimate calorie-dense foods by 50–200% when eyeballing portions. A small handful can easily be 300+ calories. The best habit: pre-portion into 30 g bags or use a scale each time. Also check whether your nuts are raw, roasted, or roasted-in-oil — the roasted-in-oil versions add extra fat that is not in the raw nutrition values.
