Carbohydrate malabsorption in infants has been found to increase nutrient losses. However, the effect of this alteration on daily metabolic rate is unknown. We assessed daily metabolic rates in infants with asymptomatic carbohydrate malabsorption (ACM) after a single fruit juice load. ⋯ Infants with ACM following fruit juice ingestion may have increased daily energy expenditure leading to increased metabolic requirements.

We investigated the effect of dietary glutamine (Gln) on specific antibody production and antioxidant enzyme activities in burned mice vaccinated with detoxified Pseudomonas exotoxin A linked with the outer membrane proteins I and F (PEIF). We also evaluated the survival rate of vaccinated and non-vaccinated burned mice infected with Pseudomonas aeruginosa. ⋯ These results suggested that vaccinated mice receiving a Gln-enriched diet may have enhanced humoral immunity and attenuated oxidative stress induced by burn injury. Also, Gln supplementation improved the survival of burned mice complicated with P. aeruginosa infection.

The aim of the present study was to assess the effects of grape seed extract (GSE) on the fat-metabolizing enzymes pancreatic lipase, lipoprotein lipase, and hormone-sensitive lipase in vitro and evaluate its potential application as a treatment for obesity. ⋯ The GSE rich in compounds that inhibit lipases may provide a safe, natural, and cost-effective weight control treatment.

Randomized Controlled Trial Clinical Trial
Effect of the ingestion of a dietary product containing Lactobacillus johnsonii La1 on Helicobacter pylori colonization in children.
Dietary components such as vegetable or probiotic microorganisms have been proposed as an alternative solution to decrease Helicobacter pylori colonization in at-risk populations. Some strains of lactic acid bacteria have been shown to exert bacteriostatic or bactericidal effects against H. pylori in in vitro and in vivo models of infection by this pathogen. We investigated whether regular ingestion of a dietary product containing Lactobacillus johnsonii La1 or L. paracasei ST11 would interfere with H. pylori colonization in children. ⋯ Regular ingestion of a product containing Lactobacillus La1 may represent an interesting alternative to modulate H. pylori colonization in children infected by this pathogen.
