Background: Intimate partner violence (IPV) is associated with children's emotional and behavioral difficulties. Psychological-IPV (P-IPV) is most common, and occurs alone or along other forms of IPV. Little is known about the longitudinal course of P-IPV exposure and its consequences on children taking into account whether or not they are present during parental arguments.

Article Synopsis
  • Researchers looked at how early childcare affects kids' development in France when they are 3.5 years old.
  • They found that kids who attended center-based care or had a childminder were less likely to have development issues compared to those who stayed home with parents.
  • However, informal childcare didn’t show a big difference in development outcomes, and the study suggests that early childcare can help kids grow better.

Background: Emulsifiers are widely used food additives in industrially processed foods to improve texture and enhance shelf-life. Experimental research suggests deleterious effects of emulsifiers on the intestinal microbiota and the metabolome, leading to chronic inflammation and increasing susceptibility to carcinogenesis. However, human epidemiological evidence investigating their association with cancer is nonexistent.

Background: Fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAPs) have been shown to be involved in gastrointestinal disorders. In view of their proinflammatory potential and their interactions with the gut microbiota, their contribution to the etiology of other chronic diseases such as cancer has been postulated. However, to our knowledge, no epidemiologic study has investigated this hypothesis so far.

Background: Nitrites and nitrates occur naturally in water and soil and are commonly ingested from drinking water and dietary sources. They are also used as food additives, mainly in processed meats, to increase shelf life and to avoid bacterial growth. Experimental studies suggested both benefits and harmful effects of nitrites and nitrates exposure on type 2 diabetes (T2D) onset, but epidemiological and clinical data are lacking.

Objectives: To study the associations between artificial sweeteners from all dietary sources (beverages, but also table top sweeteners, dairy products, etc), overall and by molecule (aspartame, acesulfame potassium, and sucralose), and risk of cardiovascular diseases (overall, coronary heart disease, and cerebrovascular disease).

Design: Population based prospective cohort study (2009-21).

Setting: France, primary prevention research.

Background Nitrates and nitrites are used as food additives in processed meats. They are also commonly ingested from water and several foods. Several short-term clinical studies suggested beneficial effects of dietary nitrates on blood pressure, while deleterious effects on oxidative damage have been suggested in some experimental studies.

Objective: To assess in 2021 the acceptance and perception of the French tax on sweetened beverages, following its revision in 2018, and factors associated with a higher level of acceptance.

Design: A cross-sectional survey within the NutriNet-Santé cohort study. Participants were invited to complete a self-reported questionnaire in March 2021.

Background And Aims: Data regarding the association between ultra-processed food (UPF) consumption and eating disorders (ED) are scarce. Our aim was to investigate whether UPF intake was associated with different ED types in a large population-based study.

Methods: 43,993 participants (mean age = 51.

Background: The food industry uses artificial sweeteners in a wide range of foods and beverages as alternatives to added sugars, for which deleterious effects on several chronic diseases are now well established. The safety of these food additives is debated, with conflicting findings regarding their role in the aetiology of various diseases. In particular, their carcinogenicity has been suggested by several experimental studies, but robust epidemiological evidence is lacking.

Background: Nitrates and nitrites occur naturally in water and soil. They are also used as food additives (preservatives) in processed meats. They could play a role in the carcinogenicity of processed meat.

Ultra-processed food : from research to guidelinesduring the past decades, food systems have shifted towards an important increase in the degree of food processing and formulation. Ultra-processed foods are products that have undergone complex processing techniques ( physical, chemical, or biological ), having a possible Impact on food matrix, and often contain cosmetic food additives (emulsifiers, sweeteners, coloring agents…) and industrial substances derived from foods (maltodextrin, hydrogenated oils, modified starches…). Several characteristics of ultra-processed foods have triggered the scientific community to investigate their potential impact on long-term human health: a lower nutritional quality compared with unprocessed or minimally Processed foods, food additives for some of which possible adverse effects have been suggested in preclinical In vitro / in vivo studies, contaminants issued from processing techniques or packaging, and modifications in the food matrix and textures, leading to increased energy intake rate and overconsumption.

The impact of dairy product consumption for long-term health remains unclear, in particular regarding their involvement in cancer etiology for frequent locations like breast or prostate. Besides, little is known about potentially different effects of dairy product subtypes. Our objective was therefore to evaluate the associations between dairy product consumption (total and subtypes) and cancer risk.

Background: Evidence is accumulating that high dietary glycaemic index (GI) and glycaemic load (GL) are potential risk factors for several metabolic disorders (e.g. type-2 diabetes, cardiovascular diseases), but remains limited concerning cancer risk.

The present study aims to describe ultra-processed food (UPF) consumption in a representative sample of French adults and to evaluate the association between UPF consumption and socioeconomic characteristics and nutritional profile of the diet. This is a cross-sectional study using food consumption data from the Étude Nationale Nutrition Santé (ENNS), conducted with 2642 participants (18-74 years old), between February 2006 and March 2007 in France. Dietary data were collected through three 24-h dietary recalls.

Background: Excessive sugar intake is now recognized as a key risk factor for obesity, type 2 diabetes, and cardiovascular diseases. In contrast, evidence on the sugar-cancer link is less consistent. Experimental data suggest that sugars could play a role in cancer etiology through obesity but also through inflammatory and oxidative mechanisms and insulin resistance, even in the absence of weight gain.

Purpose: Red and processed meats are recognized by the International Agency for Research on Cancer as probably carcinogenic and carcinogenic to humans, respectively. Heme iron has been proposed as a central factor responsible for this effect. Furthermore, anxiety affects the intestinal barrier function by increasing intestinal permeability.

Background: Ultra-processed food (UPF) consumption has increased drastically worldwide and already represents 50%-60% of total daily energy intake in several high-income countries. In the meantime, the prevalence of overweight and obesity has risen continuously during the last century. The objective of this study was to investigate the associations between UPF consumption and the risk of overweight and obesity, as well as change in body mass index (BMI), in a large French cohort.

Background: Mounting evidence, yet with varying levels of proof, suggests that dietary fibers (DFs) may exert a protective role against various chronic diseases, but this might depend on the DF type and source.

Objectives: Our objectives were to assess the associations between the intake of DFs of different types [total (TDF), soluble (SF), insoluble (IF)] and from different sources (fruits, vegetables, whole grains, legumes, potatoes and tubers) and the risk of cardiovascular diseases (CVDs), cancer, type 2 diabetes (T2D), and mortality in the large-scale NutriNet-Santé prospective cohort (2009-2019).

Methods: Overall, 107,377 participants were included.
