Randomized Controlled Trial
Postprandial substrate use in overweight subjects with the metabolic syndrome after isomaltulose (Palatinose™) ingestion.
Dietary interventions with a low glycemic index have shown to be successful for the prevention and therapy of the metabolic syndrome. In the present study, we investigated the postprandial metabolic response at rest and during physical activity the low glycemic carbohydrate isomaltulose (Palatinose™) intake compared with a conventional carbohydrate (glucose syrup/sucrose [glc/suc]) with a higher glycemic index. ⋯ In obese subjects with insulin resistance and the metabolic syndrome, the partial substitution of carbohydrates with a higher glycemic index in foods and drinks by Palatinose™ resulted in greater postprandial fat oxidation at rest and during physical activity. It is hypothesized that this increased fat oxidation may confer further benefits for long-term weight management and for an improvement in metabolic risk factors.

Randomized Controlled Trial
Eicosapentaenoic and docosahexaenoic acids, cognition, and behavior in children with attention-deficit/hyperactivity disorder: a randomized controlled trial.
To determine the effects of an eicosapentaenoic acid (EPA)-rich oil and a docosahexaenoic acid (DHA)-rich oil versus an ω-6 polyunsaturated fatty acid-rich safflower oil (control) on literacy and behavior in children with attention-deficit/hyperactivity disorder (ADHD) in a randomized controlled trial. ⋯ Increases in erythrocyte ω-3 polyunsaturated fatty acids, specifically DHA, may improve literacy and behavior in children with ADHD. The greatest benefit may be observed in children who have comorbid learning difficulties.

Randomized Controlled Trial
Influence of yeast-derived 1,3/1,6 glucopolysaccharide on circulating cytokines and chemokines with respect to upper respiratory tract infections.
Wellmune WGP is a food supplement containing a refined 1,3/1,6 glucopolysaccharide that improves the antimicrobial activity of the innate immune cells by the priming of lectin sites. This study aimed to investigate whether Wellmune decreases the frequency and severity of upper respiratory tract infection (URTI) symptoms over 90 d during the peak URTI season in healthy university students. The secondary aims included an assessment of plasma cytokine and chemokine levels. ⋯ Wellmune may decrease the duration and severity of URTI. Larger studies are needed to demonstrate this.

Randomized Controlled Trial
High-carbohydrate/low-protein-induced hyperinsulinemia does not improve protein balance in children after cardiac surgery.
In pediatric cardiac surgery, fluid-restricted low-protein (LoProt) diets account for cumulative protein deficits with increased morbidity. In this setting, we aimed to inhibit proteolysis by a high-carbohydrate (HiCarb)-intake-induced hyperinsulinemia and improve protein balance. ⋯ In children with fluid restriction after cardiac surgery, a HiCarb/LoProt diet compared with a NormCarb/LoProt diet stimulates insulin secretion but does not inhibit proteolysis further and therefore cannot be advocated for this purpose.

Randomized Controlled Trial Comparative Study
Superiority of a fish oil-enriched emulsion to medium-chain triacylglycerols/long-chain triacylglycerols in gastrointestinal surgery patients: a randomized clinical trial.
Compared with soybean oil, a fish oil-enriched emulsion can improve the clinical outcomes of patients requiring parenteral nutrition. However, the superiority of fish oil emulsion to medium-chain triacylglycerols/long-chain triacylglycerols for short-term administration has seldom been discussed. ⋯ Gastrointestinal surgery patients benefited from a fish oil-enriched emulsion rather than medium-chain triacylglycerols/long-chain triacylglycerols in the amelioration of liver function and immune status. The positive association of tumor necrosis factor-α and nuclear factor-κB might be involved in the potential anti-inflammation mechanism of fish oil.
