NELIP reduces the risk of excessive pregnancy weight gain with minimal weight retention at 2 months postpartum in OW and OB women. This intervention may assist OW and OB women in successful weight control after childbirth.

Results suggest that a prenatal nutrition and exercise program regardless of exercise intensity, reduced excessive GWG and decreased weight retention at 2 mopp in women of normal weight before pregnancy.

BackgroundThe positive influences of glucagon-like peptide-1 (GLP-1) on blood glucose homeostasis, appetite sensations, and food intake provide a strong rationale for its therapeutic potential in the nutritional management of obesity and type 2 diabetes.AimTo summarize GLP-1 physiology and the nutritional modulation of its secretion in the context of obesity and type 2 diabetes management.FindingsGLP-1 is mainly synthesized and secreted by enteroendocrine L-cells of the gastrointestinal tract. Its secretion is partly mediated by the direct nutrient sensing by G-protein coupled receptors which specifically bind to monosaccharides, peptides and amino-acids, monounsaturated and polyunsaturated fatty acids as well as to short chain fatty acids. Foods rich in these nutrients, such as high-fiber grain products, nuts, avocados and eggs also seem to influence GLP-1 secretion and may thus promote associated beneficial outcomes in healthy individuals as well as individuals with type 2 diabetes or with other metabolic disturbances.ConclusionThe stimulation of endogenous GLP-1 secretion by manipulating the composition of the diet may be a relevant strategy for obesity and type 2 diabetes management. A better understanding of the dose-dependent effects as well as the synergistic effects of nutrients and whole foods is needed in order to develop recommendations to appropriately modify the diet to enhance GLP-1 beneficial effects.

The study explores the dietary acculturation process among first-generation immigrant families from sub-Saharan Africa or the Caribbean living in Ottawa (Canada). In-depth qualitative interviews were conducted with 12 mothers. The interaction between accelerating factors and other mediating factors resulted in a spiral of dietary changes triggered by immigration. The spiral evolved at different paces from traditional to acculturated and toward healthy or unhealthy diets and was hard to stop or to change in its direction once it started. Findings call for enhancing immigrant mothers' food access, food literacy and nutrition-related parenting skills, and their children's school food environment.
