The NOVA system is a way of classifying the level of processing a food has undergone; ranging from un-processed to ultra-processed. Ultra-processed foods (UPFs) are nutritionally imbalanced and are often highly calorific. Processed foods (PFs) are the next level down from UPFs and usually have added salt or sugar. Both foods pose a potential health-risk if eaten in excess, with high blood pressure being a potential resulting disease. This systematic review and meta-analysis aimed to determine the relationship between the consumption of PFs and UPFs and high blood pressure in adults. The results showed that as the consumption of UPFs increased, so did the risk for high blood pressure, however this relationship was not seen with the consumption of PFs. It was concluded that the high consumption of UPFs is associated with a greater risk of developing high blood pressure in adults and older people. This study could be used by healthcare professionals to recommend a diet without UPFs to those who are at risk of high blood pressure or in those who have already been diagnosed.
Abstract
The increase in the availability of processed and ultra-processed foods has altered the eating patterns of populations, and these foods constitute an exposure factor for the development of arterial hypertension. This systematic review analyzed evidence of the association between consumption of processed/ultra-processed foods and arterial hypertension in adults and older people. Electronic searches for relevant articles were performed in the PUBMED, EMBASE and LILACS databases. The review was conducted following the PRISMA guidelines and the Newcastle-Ottawa Scale. The search of the databases led to the retrieval of 2323 articles, eight of which were included in the review. A positive association was found between the consumption of ultra-processed foods and blood pressure/arterial hypertension, whereas insufficient evidence was found for the association between the consumption of processed foods and arterial hypertension. The results reveal the high consumption of ultra-processed foods in developed and middle-income countries, warning of the health risks of such foods, which have a high energy density and are rich in salt, sugar and fat. The findings underscore the urgent need for the adoption of measures that exert a positive impact on the quality of life of populations, especially those at greater risk, such as adults and older people.

Plain language summary
Unhealthy diets are recognized as a major determinant of the occurrence of non-communicable diseases (NCDs). The aim of this study was to summarize the evidence for the association between ultra-processed food (UPFs) consumption and health outcomes. This study is a systemic review of 20 published epidemiological studies (12 cohort and 8 cross-sectional studies), with a total of 334,114 participants and 10 diseases. Results indicate a positive association between UPFs consumption and risk of all-cause mortality, overall cardiovascular diseases, coronary heart diseases, cerebrovascular diseases, hypertension, metabolic syndrome, overweight and obesity, depression, irritable bowel syndrome, overall cancer, postmenopausal breast cancer, gestational obesity, adolescent asthma and wheezing, and frailty. However, on the contrary, there was not an obvious association with cardiovascular disease mortality, prostate and colorectal cancer, gestational diabetes mellitus and gestational overweight. Authors conclude that their findings encouraged a decrease in UPFs consumption and an increase in the proportion of unprocessed or minimally processed foods, such as fruits and vegetables.
Abstract
BACKGROUND Consumption of ultra-processed foods (UPFs) plays a potential role in the development of obesity and other diet-related noncommunicable diseases (NCDs), but no studies have systematically focused on this. This study aimed to summarize the evidence for the association between UPFs consumption and health outcomes. METHODS A comprehensive search was conducted in PubMed, Embase, and Web of Science to identify all relevant studies. Epidemiological studies were included, and identified studies were evaluated for risk of bias.A narrative review of the synthesized findings was provided to assess the association between UPFs consumption and health outcomes. RESULTS 20 studies (12 cohort and 8 cross-sectional studies) were included in the analysis, with a total of 334,114 participants and 10 health outcomes. In a narrative review, high UPFs consumption was obviously associated with an increased risk of all-cause mortality, overall cardiovascular diseases, coronary heart diseases, cerebrovascular diseases, hypertension, metabolic syndrome, overweight and obesity, depression, irritable bowel syndrome, overall cancer, postmenopausal breast cancer, gestational obesity, adolescent asthma and wheezing, and frailty. It showed no significant association with cardiovascular disease mortality, prostate and colorectal cancers, gestational diabetes mellitus and gestational overweight. CONCLUSIONS This study indicated a positive association between UPFs consumption and risk of several health outcomes. Large-scale prospective designed studies are needed to confirm our findings.

Plain language summary
Inflammatory Bowel Diseases (IBDs), such as Crohn’s disease (CD) and Ulcerative Colitis (UC) are becoming increasingly common. Diet is thought to play a role in the development of IBDs. The consumption of Ultra Processed Food (UPF) is increasing and has been associated with a higher risk of some chronic diseases. Food additives may be an aspect of UPF responsible for its harmful effects. This literature review examined the role of food additives in the development and severity of IBDs. The authors discuss how common food additives such as salt, emulsifiers, stabilisers, bulking agents, sweeteners, and food colouring may promote inflammation and disrupt gut bacteria. Metals and compounds found in food packaging such as aluminium and bisphenol A (BPA) may trigger intestinal permeability and increase inflammatory markers. Much of the evidence available is based on clinical trials on animals, whilst epidemiological studies on food additives and IBD risk are still limited. The authors concluded that the majority of food consumed by IBD patients should be home-cooked in order to reduce exposure to additives in the diet.
Abstract
Inflammatory bowel diseases (IBDs) develop in genetically predisposed individuals in response to environmental factors. IBDs are concomitant conditions of industrialized societies, and diet is a potential culprit. Consumption of ultra-processed food has increased over the last decade in industrialized countries, and epidemiological studies have found associations between ultra-processed food consumption and chronic diseases. Further studies are now required to identify the potential culprit in ultra-processed food, such as a poor nutritional composition or the presence of food additives. In our review, we will focus on food additives, i.e., substances from packaging in contact with food, and compounds formed during production, processing, and storage. A literature search using PubMed from inception to January 2019 was performed to identify relevant studies on diet and/or food additive and their role in IBDs. Manuscripts published in English from basic science, epidemiological studies, or clinical trials were selected and reviewed. We found numerous experimental studies highlighting the key role of food additives in IBD exacerbation but epidemiological studies on food additives on IBD risk are still limited. As diet is a modifiable environmental risk factor, this may offer a scientific rationale for providing dietary advice for IBD patients.
