SummaryFactor VII coagulant activity (FVIIc) is associated with an increased risk of fatal ischaemic heart disease (IHD). Several reports have suggested that dietary fat intake or hypertriglyceridaemia are associated with elevated levels of FVII. This study demonstrates that an intake of long-chain fatty acids sufficient to induce postprandial lipaemia in healthy subjects leads to a substantial elevation in both FVIIc and the concentration of FVII circulating in the activated form. Such an increase in FVIIc could not be induced by medium-chain triglycerides. These results suggest that the consumption of a sufficient amount of long-chain triglycerides to induce postprandial lipaemia induces the activation of FVII.

Recent evidence has highlighted that fat accumulation, particularly abdominal fat distribution, is strongly associated with metabolic disturbance. It is also well-recognized that the metabolic responses to variations in macronutrients intake can affect body composition. Previous studies suggest that the quality of dietary fats can be considered as the main determinant of body-fat deposition, fat distribution, and body composition without altering the total body weight; however, the effects of dietary fats on body composition have controversial results. There is substantial evidence to suggest that saturated fatty acids are more obesogen than unsaturated fatty acids, and with the exception of some isomers like conjugate linoleic acid, most dietary trans fatty acids are adiposity enhancers, but there is no consensus on it yet. On the other hand, there is little evidence to indicate that higher intake of the n-3 and the n-6 polyunsaturated fatty acids can be beneficial in attenuating adiposity, and the effect of monounsaturated fatty acids on body composition is contradictory. Accordingly, the content of this review summarizes the current body of knowledge on the potential effects of the different types of dietary fatty acids on body composition and adiposity. It also refers to the putative mechanisms underlying this association and reflects on the controversy of this topic.

Abstract Objectives The objectives of this study were to determine the effect of 2’fucosyllactose (2’FL) and fat blends on growth, body composition and fatty acid profile of the liver and brain using the neonatal pig as a model for the human infant. Methods Pigs (3 d old) were randomly assigned to either: 1. control, 2. Palm Olein (PO) fat blend – Low 2'-FL, 3. PO – High 2'-FL, 4. High oleic acid (HO) – Low 2'-FL, 5. HO FB – High 2'-FL, 6. PO FB – GLA, or 7. kept with their sows. Pigs in groups 1 to 6 received 250 ml·kg−1·d−1 of formula in 5 equal meals for 15 d. On day 14 of the study, groups 1–6 received intraperitoneal E. coli LPS challenge at 100 µg·kg−1 weight. Results Body weight was greater for piglets fed by sows than those in the other groups (P < 0.001). In addition, % fat and bone mineral content were higher in the sow-fed group while lean % was less sow-fed piglets (group 7) compared with those in the other groups (P < 0.05). Only longissimus weight expressed as a % of body weight, was greater for group 7 compared with all other groups (P < 0.001). Soleus, semitendinosus, brain, heart and spleen weights as a % of body weight were similar across all groups. However, liver weight as a % of body weight was greater in groups 1–6 (3.7%) compared with group 7 (2.8%; P < 0.001). The proportion of brain 16:1 fatty acid was less (0.83%) for groups 1–6 than for group 7 pigs (1.08%; P < 0.0001). The proportion of 20:3 N6 was greatest (0.66%) for group 3 compared with groups 1 and 4 (0.55%; P < 0.05). In addition, the proportion of 20:5 N3 was greatest (0.12%) for group 3 compared with groups 1 and 7 (0.07%; P < 0.05). The proportion of liver 16:1, 18:0, and 18:1 cis-11 fatty acids were greater for group 7 (2.3, 23, 2.2%) than groups 1–6 (0.2, 20, 1.2%; P < 0.0001). Conversely, the contribution of 14:0, 18:1 cis-9, 18:3 N6 cis-6,9,12, and 22:6 N3 were greater for pigs in groups 1–6 (1.3, 0.6, and 14, 7.8%) compared with those in group 7 (0.5, 8.5, 0.2 and 3.5%; P < 0.0001). Conclusions Our data suggest that feeding 2’fucosyllactose had no effect on the body weight gain and composition in neonatal pigs. Our data also suggest that dietary fatty acids have a greater effect on liver than on brain fatty acid composition. Funding Sources Funding for the work was provided by Perrigo Nutritionals, LLC.
