A new simplified dietary history method for measuring intake of energy and macronutrients

Article Abstract:

A study was done to evaluate the efficiency of the dietary history method in determining individual intakes of energy and macronutrients. The method involves grouping of several food items into codes which facilitates interview and nutrient calculation. Results of the evaluation show that this dietary history method can be used in assessing relative individual intake of energy and macronutrients but values obtained may be crude for other experiments due to its use of aggregated data.

The relation of the accumulation of cadmium in human placenta to the intake of high-fibre grains and maternal iron status

Article Abstract:

Thirty-nine pregnant women participated in a study to investigate the extent intake of grain fiber and maternal iron status affect cadmium accumulation during pregnancy. Results show that women who ate less grain fiber and maintained better iron status during pregnancy had lower cadmium accumulation in the placenta. Furthermore, it was shown that low iron status during the third trimester of pregnancy can cause as much as a four-fold increase in placental absorption of cadmium.

Repeated 24-h recalls with young schoolchildren. A feasible alternative to dietary history from parents?

Article Abstract:

Interviews with children rather than with parents can be a better method of dietary survey. Children of at least eight years can easily recollect their activities including dietary intake over a period of 24 hours without the help of parents, but children below this age are unable to do so. Interviewing children alone rather than including parents in the survey can reduce time and expense, though care should be taken not to fatigue the children.
