Randomized Controlled Trial Comparative Study Clinical Trial
Jejunal feeding is followed by a greater rise in plasma cholecystokinin, peptide YY, glucagon-like peptide 1, and glucagon-like peptide 2 concentrations compared with gastric feeding in vivo in humans: a randomized trial.
Jejunal feeding is preferred instead of gastric feeding in patients who are intolerant to gastric feeding or at risk of aspiration. However, the impact of gastric feeding compared with that of jejunal feeding on postprandial circulating plasma glucose and amino acid concentrations and the associated endocrine response in vivo in humans remains largely unexplored. ⋯ Enteral nutrition with gastric or jejunal feeding in healthy young men results in similar postprandial plasma amino acid and glucose concentrations. However, the endocrine response differs substantially, with higher peak plasma cholecystokinin, PYY, GLP-1, and GLP-2 concentrations being attained after jejunal feeding. This effect may result in an improved anabolic response, greater insulin sensitivity, and an improved intestinotropic effect. Nevertheless, it may also lead to delayed gastric emptying. This trial was registered at trialregister.nl as NTR2801.

The association between saturated fatty acid (SFA) intake and ischemic heart disease (IHD) risk is debated. ⋯ In this Dutch population, higher SFA intake was not associated with higher IHD risks. The lower IHD risk observed did not depend on the substituting macronutrient but appeared to be driven mainly by the sums of butyric through capric acid, the sum of pentadecylic and margaric acid, myristic acid, and SFAs from dairy sources. Residual confounding by cholesterol-lowering therapy and trans fat or limited variation in SFA and PUFA intake may explain our findings. Analyses need to be repeated in populations with larger differences in SFA intake and different SFA food sources.

Randomized Controlled Trial Comparative Study
Vitamin D activity of breast milk in women randomly assigned to vitamin D3 supplementation during pregnancy.
Human milk is typically low in vitamin D activity (VDA). Whether the vitamin D content of breast milk at birth can be increased by supplementing the mother during pregnancy has not been reported to the best of our knowledge. ⋯ Maternal vitamin D supplementation during pregnancy of 2000 IU/d (compared with 1000 IU/d and with a placebo) results in a higher VDA of breast milk ≥2 mo postpartum. This trial was registered at the Australian New Zealand Clinical Trials Registry as ACTRN12610000483055.
