Abstract
Abstract Objective To assess the prospective associations between consumption of ultra-processed foods and risk of cardiovascular diseases. Design Population based cohort study. Setting NutriNet-Sante cohort, France 2009-18. Participants 105 159 participants aged at least 18 years. Dietary intakes were collected using repeated 24 hour dietary records (5.7 for each participant on average), designed to register participants’ usual consumption of 3300 food items. These foods were categorised using the NOVA classification according to degree of processing. Main outcome measures Associations between intake of ultra-processed food and overall risk of cardiovascular, coronary heart, and cerebrovascular diseases assessed by multivariable Cox proportional hazard models adjusted for known risk factors. Results During a median follow-up of 5.2 years, intake of ultra-processed food was associated with a higher risk of overall cardiovascular disease (1409 cases; hazard ratio for an absolute increment of 10 in the percentage of ultra-processed foods in the diet 1.12 (95% confidence interval 1.05 to 1.20); P Conclusions In this large observational prospective study, higher consumption of ultra-processed foods was associated with higher risks of cardiovascular, coronary heart, and cerebrovascular diseases. These results need to be confirmed in other populations and settings, and causality remains to be established. Various factors in processing, such as nutritional composition of the final product, additives, contact materials, and neoformed contaminants might play a role in these associations, and further studies are needed to understand better the relative contributions. Meanwhile, public health authorities in several countries have recently started to promote unprocessed or minimally processed foods and to recommend limiting the consumption of ultra-processed foods. Study registration ClinicalTrials.gov NCT03335644.

Ultra-processed foods provide 58 % of energy intake and 89 % of added sugars in the American diet. Nevertheless, the association between ultra-processed foods and excess weight has not been investigated in a US sample. The present investigation therefore aims to examine the association between ultra-processed foods and excess weight in a nationally representative sample of US adults. We performed a cross-sectional analysis of anthropometric and dietary data from 15 977 adults (20–64 years) parti...

Ultra-processed foods (UPF) consumption has increased over the last decades and is raising concerns about potential adverse health effects. Our objective was to assess the association between UPF consumption and four functional gastrointestinal disorders (FGIDs): irritable bowel syndrome (IBS), functional constipation (FC), functional diarrhea (FDh), and functional dyspepsia (FDy), in a large sample of French adults. We analyzed dietary data of 33,343 participants from the web-based NutriNet-San...

Abstract Background Long-term exposure to acrylamide (AA) from diet sources may induce oxidative stress and chronic inflammation. However, the association between AA exposure and the prevalence of cardiovascular diseases (CVD) remains unclear. Objectives We aimed to examine the association between blood exposure levels of AA biomarkers and the prevalence of main types of CVD in a general population of US adults. Methods We analyzed the associations between AA hemoglobin biomarkers [hemoglobin ad...

We described the contribution of ultra-processed foods in the U.K. diet and its association with the overall dietary content of nutrients known to affect the risk of chronic non-communicable diseases (NCDs). Cross-sectional data from the U.K. National Diet and Nutrition Survey (2008–2014) were analysed. Food items collected using a four-day food diary were classified according to the NOVA system. The average energy intake was 1764 kcal/day, with 30.1% of calories coming from unprocessed or minim...

Importance Prior studies have demonstrated lower all-cause mortality in individuals who are overweight compared with those with normal body mass index (BMI), but whether this may come at the cost of greater burden of cardiovascular disease (CVD) is unknown. Objective To calculate lifetime risk estimates of incident CVD and subtypes of CVD and to estimate years lived with and without CVD by weight status. Design, Setting, and Participants In this population-based study, we used pooled individual-...

The dietary pattern that characterizes the Western diet is strongly associated with obesity and related metabolic diseases, but biological mechanisms supporting these associations remain largely unknown. We argue that the Western diet promotes inflammation that arises from both structural and behavioral changes in the resident microbiome. The environment created in the gut by ultra-processed foods, a hallmark of the Western diet, is an evolutionarily unique selection ground for microbes that can...

We examined the association between the consumption of ultra-processed foods and adiposity in a nationally representative sample of the UK adult population. We studied 6,143 participants (19 to 96 years, 51.6% female) sampled by the UK National Diet and Nutrition Survey (2008–16). Food items reported in four-day food diary were classified according to the NOVA system. Multiple linear and logistic regressions were used to evaluate associations between the dietary contribution of ultra-processed f...

Advanced glycation end products (AGEs) are a heterogeneous group of molecules produced, non-enzymatically, from the interaction between reducing sugars and the free amino groups of proteins, nucleic acids and lipids. AGEs are formed as a normal consequence of metabolism but can also be absorbed from the diet. They have been widely implicated in the complications of diabetes affecting cardiovascular health, the nervous system, eyes and kidneys. Increased levels of AGEs are also detrimental to met...

Until recently, the noncommunicable disease (NCD) category was composed of four chronic diseases (cancer, cardiovascular disease, diabetes and chronic respiratory disease) and four shared, 'modifiable' behavioural risk factors (smoking, diet, physical activity and alcohol). In late 2018, the NCD category was expanded to include mental health as an additional disease outcome and air pollution as an explicit environmental risk factor. The newly-expanded NCD category connects behavioural and enviro...

Background. More than 330 food additives (e.g. artificial sweeteners, emulsifiers, dyes) are authorized in Europe, with a great variability of use across food products. Objective. The objective of this study was to investigate the distribution and co-occurrence of food additives in a large-scale database of foods and beverages available on the French market. Design. The open access crowdsourced Open Food Facts database (https://world.openfoodfacts.org/) was used to retrieve the composition of fo...

Abstract Background Ultra-processed foods are highly processed foods which are manufactured with industrial substances to increase convenience and palatability. Some organophosphate esters (OPEs) are used as flame retardants and plasticizers and have been detected in food samples, particularly processed foods. However, little is known about dietary sources of OPEs or whether higher consumption of ultra-processed foods increases exposures. Objectives We evaluated whether higher consumption of ult...

Policies that require front-of-package (FoP) nutrient warnings are becoming increasingly common across the globe as a strategy to discourage excess consumption of sugary drinks and ultra-processed food. However, a better understanding of the pathway through which FoP nutrient warnings work, as well as a review of how outcomes being measured in recent studies map onto this pathway, are needed in order to inform policy on the most effective FoP label design for reducing purchases of ultra-processe...

The qualitative NOVA classification of foods according to their degree of processing is widely used worldwide by researchers. NOVA defines ultra-processed foods (UPFs) by the presence of processed industrial and cosmetic ingredients and additives to modify the sensory properties (aroma, taste, colour and texture) of the reconstituted food. Some drastic processes directly applied to food are also markers of ultra-processing. However, in the intent to develop an elaborated tool for industries and ...
