  1. Trans fatty acids in the Scottish diet : an assessment using a semi-quantitative food-frequency questionnaire.

    Article - En anglais

    Trans fatty acids produced during hardening of oils have been associated with higher cholesterol levels and increased risk of heart disease.

    The potential risk from trans fatty acids may be greater in populations with relatively low intakes of essential fatty acids such as the Scots, who also have a high prevalence of heart disease.

    Means and ranges of trans fatty acid intakes are reported here for a Scottish population.

    A semi-quantitative food-frequency questionnaire was used to survey the diet of 10359 Scottish men and women aged 40-59 years in 1984-6 as part of the baseline Scottish Heart Health Study.

    Trans fatty acid levels were calculated for each food item on the questionnaire and the total subdivided into that which is derived naturally (primarily by bacterial fermentation in ruminants) and that which is produced during industrial hydrogenation (hardening) of vegetable and fish oils.

    Means and ranges of intakes of each trans fatty acid variable were calculated by sex, age, smoking and social class groups.

    Mean total trans fatty acid intakes for men were 7.1 (SD 3.1) g/d, 2.7 (SD 2.9)% energy and for women were 6.4 (SD 2.9) g/d, 3.3 (SD 3.0)% energy.

    Industrially hydrogenated trans fatty acids made up nearly 58% of the total intake for men and 61% for women, with about 60% coming from cakes, biscuits and sweets, and 20% coming from the cheaper hard margarines.

    The main sources of the naturally derived trans fatty acids were red meat (27%), milk (20...
