Fibre Intake Calculator
Your daily fibre target from the IOM's 14 g per 1,000 kcal rule, with food equivalents to make it concrete.
Most adults eat barely half their fibre target — the gap output shows yours against the ~17 g typical Western intake. Concrete equivalents: a bowl of dal ≈ 8 g, an apple with skin ≈ 4.5 g, 100 g of oats ≈ 10 g, two rotis ≈ 5 g. Increase gradually and drink water with it; jumping 20 g overnight earns you bloating, not health.
