Estimate of dietary ganglioside intake in a group of healthy Edmontonians based on selected foods

The daily ganglioside intake of 19 healthy individuals was estimated based on consumption of specific foods from food records. The ganglioside content of 6 specific foods commonly consumed by healthy individuals living in the Edmonton, Alberta, Canada area was 0.51 ± 0.08 μg NANA/g (1% milk), 0.73 ± 0.09 μg NANA/g (yogurt), 0.72 ± 0.05 μg NANA/g (cheddar cheese), 1.73 ± 0.59 μg NANA/g (egg yolk), 1.70 ± 0.17 μg NANA/g (cooked ground beef), and 0.83 ± 0.32 μg NANA/g (canned tuna). The highest ganglioside content from foods analyzed, gram for gram, was found in egg yolk and cooked ground beef. The mean ganglioside intake from this group of healthy individuals was determined (i.e. <100 μg N-acetylneuraminic acid/4187 kJ daily). The findings of this study may be useful for studies investigating ganglioside concentrations of foods or usual ganglioside intake in a healthy population.
