Randomized Controlled Trial Clinical Trial
Effect of hypocaloric meals with different macronutrient compositions on energy metabolism and lung function in obese women.
We investigated the effect of hypocaloric mixed diets with different proportions of carbohydrate, protein, and fat on resting metabolic rate and the thermic effect of food in obese women. ⋯ Obese women with normal lung function tests and consuming mixed hypocaloric diets showed no alteration in resting metabolic rate and a reduced or absent thermic effect of food independently of the macronutrient composition.

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.
