Did fat intake in the United States really decline between 1989-1991 and 1994-1996?

The objectives of this study were to determine changes in fat and energy intakes in the United States between 1989-1991 and 1994-1996, and to examine the implications of expressing fat intake in grams vs as a percent of total energy intake. The source of data was the Continuing Survey of Food Intake by Individuals. The results suggest that intake of energy rose between the 2 time periods, primarily due to higher carbohydrate intake.

Differential modulation of Toll-like receptors by fatty acids: preferential inhibition by n-3 polyunsaturated fatty acids.

Human subjects consuming fish oil showed a significant suppression of cyclooxygenase-2 (COX-2) expression in blood monocytes when stimulated in vitro with lipopolysaccharide (LPS), an agonist for Toll-like receptor 4 (TLR4). Results with a murine monocytic cell line (RAW 264.7) stably transfected with COX-2 promoter reporter gene also demonstrated that LPS-induced COX-2 expression was preferentially inhibited by docosahexaenoic acid (DHA, C22:6n-3) and eicosapentaenoic acid (EPA, C20:5n-3), the major n-3 polyunsaturated fatty acids (PUFAs) present in fish oil.
