Essential Fatty Acids and Human Nutrition

II. Serum Level for Unsaturated Fatty Acids in Poorly-Nourished Infants and Children¹

One Figure

Department of Pediatrics, University of Texas Medical Branch, Galveston

The blood serum levels for the total fatty acids, dienoic, trienoic, tetraenoic and hexaenoic acids, were determined on 57 poorly-nourished infants and children.

There were no significant differences in the amount of the total fatty acids in serum of children in fair and poor nutritional states as compared with well-nourished children.

Dienoic, tetraenoic and hexaenoic acid levels in the serum of inadequately nourished children were significantly lower than in healthy children.

The trienoic acid level in the serum of inadequately nourished children was significantly higher than in healthy children.

Absorption data indicate the presence of a small amount of pentaenoic acid in the serum of all children. E^1%_{1 cm} values at 3,475A due to pentaenoic acid alone did not vary with nutritional status.
