The 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. To summarize GLP-1 physiology and the nutritional modulation of its secretion in the context of obesity and type 2 diabetes management. GLP-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. The 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.

Background: The menopausal transition involves multiple biological and psychosocial challenges that may render middle-aged women vulnerable to body image concerns. Objective: The aim of this study was to summarize evidence on the associations between menopause and body image perception in healthy middle-aged women. Design: This study is a systematic review of observational studies. Data sources and methods: Menopause-related exposure measures included menopausal stages, menopausal symptoms, and reproductive hormone levels during the menopausal transition. Studies investigating body image as an outcome, including through a positive (e.g. body self-esteem) or negative (e.g. body dissatisfaction) lens, were considered eligible. Articles published before March 2023 were identified through MEDLINE, PsycINFO, and Embase and underwent double screening, extraction, and quality assessment by two independent investigators. Characteristics and results were summarized using narrative synthesis. Results: A total of 820 non-duplicate records were identified, with 18 observational studies deemed eligible for inclusion after full-text screening. All studies investigating menopausal symptoms and body image ( n = 6) found some significant association between them, with a higher frequency, intensity, or number of symptoms being associated with greater body image concern. Differences in body image perception between menopausal stages were inconsistent across studies ( n = 12), while evidence of potential associations between reproductive hormones and body image was minimal ( n = 2). Findings should be interpreted with caution as 17 of the included studies used a cross-sectional design, and not all studies adjusted their analyses for relevant confounders. Conclusion: Overall, menopausal symptoms showed relatively consistent associations with a more negative body image perception. Additional research is required to understand the potential role of menopausal stages and reproductive hormone levels in the body image perception of middle-aged women and to confirm the direction of reported associations.

Purpose: Food insecurity (FI) is an important social determinant of health and is linked with higher health care costs. There is a high prevalence of FI among recent migrant households in Canada. The purpose of this paper is to evaluate the prevalence of FI in Sub-Saharan African and Caribbean migrants in Ottawa, and to explore determinants of FI in that population. Design/methodology/approach: A cross-sectional study was conducted among 190 mothers born in Sub-Saharan Africa or the Caribbean living in Ottawa and having a child between 6 and 12 years old. Health Canada’s Household Food Security Survey Module was used to evaluate participants’ food security in the past 12 months. χ² tests and multivariate logistic regression analyses were used to measure determinants of FI (n=182). Findings: A very high rate of FI (45.1 percent) was found among participants. When numerous determinants of FI were included in a multivariate model, household FI was associated with Caribbean origin, low education attainment, lone motherhood, living in Canada for five years or less and reliance on social assistance. Originality/value: These findings highlight the need for FI to be explicitly addressed in migrant integration strategies in order to improve their financial power to purchase sufficient, nutritious and culturally acceptable foods. Enhancing migrants’ access to affordable child care and well-paid jobs, improving social assistance programs and providing more affordable subsidized housing programs could be beneficial.
