Research has shown that pleasure affects nutrient absorption. In a 1970s study of Swedish and Thai women, it was found that when the Thai women were eating their own (preferred) cuisine, they absorbed about 50% more iron from the meal than they did from eating the unfamiliar Swedish food. And the same was true in the reverse for the Swedish women. When both groups were split internally and one group given a paste made from the exact same meal and the other was given the meal itself, those eating the paste absorbed 70% less iron than those eating the food in its normal state.
