The consumption of a low-fat diet is advocated as beneficial in the pr
evention of cardiovascular disease. Because of still existing controve
rsy the hypothesis whether low fat intake less than or equal to 30% of
total calories can maintain optimal growth and supply the desirable q
uantity of micronutrients was tested in a cohort of 500 children in pr
eschool age. The children, apparently in good health and without any s
pecial dietary regimen, were stratified according to fat intake in thr
ee groups: <30, 30-40 and greater than or equal to 40% of calories pro
vided by fat. Our findings indicate that children with low fat intake
were at a quite important risk of unsatisfactory intakes of fat-solubl
e vitamins, and also the nutritional density of consumed food was lowe
r. The proportions of saturated (SFA), polyunsaturated and monounsatur
ated fatty acids were rather similar in all three groups, but choleste
rol and SFA intakes decreased significantly in those with low fat inta
ke. Serum cholesterol and triglyceride levels were however not signifi
cantly influenced.
