Fatty acid content and composition of infant formulas and cereals
1981
Hanson, Julie M. | Kinsella, John E.
Fat provided 39-47% of total calories in 6 standard infant formulas and 6 milk allergy infant formulas, as compared with human milk in which fat supplies an average of 55% of total calories. The level of C16:0 fatty acids in the formulas was lower than that in milk, although C18:0 fatty acid levels were similar. These fatty acid components appear to resemble milk in their effects on calcium absorption. High levels of C18:2 were observed in many formulas. Medium-chain fatty acids in most formulas came from the lauric fats of coconut or palm oil sources used to improve fat digestibility. Infant formulas contained sufficient linoleic acid levels to ensure the synthesis of long-chain polyunsaturated fatty acids needed by the developing infant for brain lipids and prostaglandins. Analysis of the fatty acid content and composition of 8 dry infant cereals indicated that oatmeal cereals contained the most fat, with fat supplying 4.5-17.2% of total calories. Trans isomers of fatty acids in these infant foods were at low levels in all samples.
