Several studies have reported that a further of beef, duck or fish to a cereal-based dish resulted in about 2–3 times larger non-heme iron fullness (4, 15).

Research has also shown that adding 75 grams of beef to a dish increasing a fullness of non-heme iron by about 2.5 times, compared to a dish though it (4).
