The study investigated the effect of small amounts of pork on nonheme-iron absorption from a meal presumed to have low iron bioavailability. In the study iron absorption was measured in 45 women, average age 24 years, who consumed four different meals.
The meals consisted of:
(i) The basic meal: rice, tomato sauce, pea purée, and a wheat roll. (phytate-rich meal low in vitamin C).
(ii) The basic meal + 25 grams of pork.
(iii) The basic meal + 50 grams of pork.
(iv) The basic meal + 75 grams of pork.
The study found:
(a) The meal with 25 grams of pork increased absorption of nonheme-iron by 20% compared to the basic meal.
(b) The meal with 50 grams of pork increased absorption of nonheme-iron by 44% compared to the basic meal.
(c) The meal with 75 grams of pork increased absorption of nonheme-iron by 57% compared to the basic meal.
The findings of the study reveal that small amounts of pork (over 50 grams) significantly increase nonheme-iron absorption from a phytate-rich meal low in vitamin C.
