About this food

How should I track Flaxseed, ground?

Flaxseed, ground is high in magnesium. Nuts like Flaxseed, ground 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.
