Phytate, the salt of phytic acid, is the primary storage
compound of phosphorus in seeds. Plant-based foods
such as unrefined cereals and legumes, including oil
seeds and nuts are the main sources of phytate in the
daily diet. Although some studies shown that phytate
may have beneficial roles as an antioxidant and anticarcinogen,
it is a well-known inhibitor of the absorption of
some essential trace elements and minerals, which may
lead to calcium, iron, magnesium and zinc deficiencies in
the body. Therefore, valid tools for measuring the phytate
intake are needed. Food frequency questionnaire (FFQ)
is commonly used as an effective, easily administered
and inexpensive dietary assessment tool. The aim of this
study was to develop a quantitative FFQ for estimating
intake of phytate in the urban Macedonian population.
Hence, the main objectives of the study were (a) to
generate an appropriate food list, portion size and food
frequency options and (b) to pretest the dietary tool
with the intent to explore its usability and to identify issues
and suggestion for its improvement. The FFQ was
developed using 3-day food intake record data from a
sample of 100 participants(of both genders, aged 15-
65 years and varying dietary patterns) living in Skopje.
From the obtained collective food data, 31 single foods
were selected and formed the basis for the food list.
For each food item, a standard serving was expressed
in commonly used portions. The frequency of intake
was assessed on an ascending eight-point scale: never,
once/month, 2 - 3 times/month, once/week, 2 - 3
times/week, 4 - 6 times/week, once/day, and twice
or more/day. Support questions on supplement use,
meal practices, demographics, anthropometrics, lifestyle,
and health status, were also included.
This study highlights the development of a quantitative
FFQ, as a dietary assessment tool for estimating
intake of phytate. The next step will involve the verification
of the FFQ reproducibility and validity.
Key words: Food frequency questionnaire, Dietary assessment tool, Phytate intake.
