Oxalates occur as end products of metabolism in a number of plant tissues; some leafy plants and some root crops contain markedly high levels of soluble and insoluble oxalates. When consumed these oxalates can bind calcium and other minerals. Measurement of oxalate content in vegetables commonly con

โฆ Synopsis
The fatty acid composition and trans fatty acid content of samples of New Zealand foods representing certain food groups have been determined by a combined gas chromatography/ infrared spectroscopy method. The mean levels of trans fatty acids in the fat portion of these foods are (g/100 g fatty acids) margarine, 16.4; table spreads, 15.7; butter/margarine blends, 9.6; butter, 6.4; pastry, 6.2; potato chips (deep fried in beef dripping), 5.6; cakes, 5.3, crackers, 2.0; sweet biscuits, 1.9; potato crisps, 0.5. Expressed as a proportion of dry weight of food the mean trans fatty acid content values are (g/100 g dry weight) margarine, 14.9; table spreads, 14.4; butter/margarine blends, 8.1; butter, 6.0; potato chips (deep fried in beef dripping), 1.6; pastry, 1.2; cakes, 0.9, crackers, 0.3; sweet biscuits, 0.2; potato crisps, 0.2. In contrast to North America, hydrogenated plant oils with high levels of trans fatty acids do not appear to be present in the New Zealand food supply.

## Abstract As a preliminary for recommended __trans__ fatty acid (TFA) consumption levels as regards health, it was essential to estimate the TFA intake level. Recent results of TFA content of foods were collected, and the total TFA, 18:1 TFA, 18:2 TFA and total conjugated linoleic acid (CLA) comp
