Fermented Food and Non-Communicable Chronic Diseases: A Review.

ABSTRACT: Fermented foods represent a significant fraction of human diets. Although their impact on health is positively perceived, an objective evaluation is still missing. We have, therefore, reviewed meta-analyses of randomized controlled trials (RCT) investigating the relationship between fermented foods and non-transmissible chronic diseases. Overall, after summarizing 25 prospective studies on dairy products, the association of fermented dairy with cancer was found to be neutral, whereas it was weakly beneficial, though inconsistent, for specific aspects of cardio-metabolic health, in particular stroke and cheese intake. The strongest evidence for a beneficial effect was for yoghurt on risk factors of type 2 diabetes. Although mechanisms explaining this association have not been validated, an increased bioavailability of insulinotropic amino acids and peptides as well as the bacterial biosynthesis of vitamins, in particular vitamin K2, might contribute to this beneficial effect. However, the heterogeneity in the design of the studies and the investigated foods impedes a definitive assessment of these associations. The literature on fermented plants is characterized by a wealth of in vitro data, whose positive results are not corroborated in humans due to the absence of RCTs. Finally, none of the RCTs were specifically designed to address the impact of food fermentation on health. This question should be addressed in future human studies.

Project description:BackgroundNon-communicable diseases [NCDs] are leading causes of ill health among women of reproductive age and an increasingly important cause of maternal morbidity and mortality worldwide. Reliable data on NCDs is necessary for accurate measurement and response. However, inconsistent definitions of NCDs make reliable data collection challenging. We aimed to map the current global literature to understand how NCDs are defined, operationalized and discussed during pregnancy, childbirth and the postnatal period. METHODS: For this scoping review, we conducted a comprehensive global literature search for NCDs and maternal health covering the years 2000 to 2020 in eleven electronic databases, five regional WHO databases and an exhaustive grey literature search without language restrictions. We used a charting approach to synthesize and interpret the data. RESULTS: Only seven of the 172 included sources defined NCDs. NCDs are often defined as chronic but with varying temporality. There is a broad spectrum of conditions that is included under NCDs including pregnancy-specific conditions and infectious diseases. The most commonly included conditions are hypertension, diabetes, epilepsy, asthma, mental health conditions and malignancy. Most publications are from academic institutions in high-income countries [HICs] and focus on the pre-conception period and pregnancy. Publications from HICs discuss NCDs in the context of pre-conception care, medications, contraception, health disparities and quality of care. In contrast, publications focused on low- and middle-income countries discuss NCDs in the context of NCD prevention. They take a life cycle approach and advocate for integration of NCD and maternal health services.ConclusionStandardising the definition and improving the articulation of care for NCDs in the maternal health setting would help to improve data collection and facilitate monitoring. It would inform the development of improved care for NCDs at the intersection with maternal health as well as through a woman's life course. Such an approach could lead to significant policy and programmatic changes with the potential corresponding impact on resource allocation.

Project description:The global shift towards diets high in sugar-sweetened beverages (SSBs) and energy dense ultra-processed foods is linked to higher prevalence of obesity, diabetes and most other noncommunicable diseases (NCDs), causing significant health costs. Chile has the highest SSB consumption in the world, very high junk food intake and very rapid increases in these poor components of the diet plus obesity prevalence. This study's purpose is to compare the effect of different tax schemes for SSBs and ultra-processed foods on nutrient availability, utilizing price-elasticities, which are estimated from a Quadratic Almost Ideal Demand System model, using the 2011-2012 Income and Expenditure survey. We take into account the high proportion of households not purchasing various food and beverage groups (censored nature of data). The food groups considered were: sweets and desserts; salty snacks and chips; meat products and fats; fruits, vegetables and seafood; cereals and cereal products; SSB ready-to-drink; SSB from concentrate; plain water, coffee and tea; and milk, which together represent 90% of food expenditures. The simulated taxes were: (1) 40% price tax on SSBs(22% above the current tax level); (2) a 5 cents per gram of sugar tax on products with added sugar; and (3) 30% price tax on all foods(27% above current tax levels) and beverages (12% above the current tax level) exceeding thresholds on sodium, saturated fat, and added sugar and for which marketing is restricted (based on a Chilean law, effective June 16 2016). Unhealthy foods are price-elastic (-1.99 for salty snacks and chips, -1.06 for SSBs ready-to-drink, and -1.27 for SSBs from concentrate), meaning that the change in consumption is proportionally larger with respect to a change in price. Results are robust to different model specification, and consistent among different socioeconomic sub-populations. Overall, the tax on marketing controlled foods and beverages is associated with the largest reduction in household purchases of sodium, added sugar, saturated fat and calorie purchases. Chile is unique in currently having instituted a small current SSB tax as well as marketing controls and front-of-package labeling of unhealthy foods and beverages. The design of a larger, more comprehensive tax to enhance the overall effect of these policies on healthier diets is a next critical step. This study shows that a large tax on the same foods and beverages already delineated as unhealthy by the marketing controls and front-of-pack labeling should prove to be more effective for promoting a healthier diet.

Project description:BackgroundNon-communicable diseases (NCDs) are a growing global health challenge disproportionately impacting low- and middle-income settings, including Ethiopia. Currently, the body of evidence describing the burden of NCDs is fragmented, inconsistent, health facility- or institution-based, and out-dated in Ethiopia. We conducted a systematic review of the literature and meta-analysis of the prevalence of NCDs in community settings in Ethiopia.Review methodologyCommunity-based quantitative studies published in English between January 1st, 2012, and June 30th, 2022, that reported on the prevalence of NCDs in Ethiopia were included. A systematic search of Medline, Embase, Scopus, CINAHL, and Global Health using pretested search terms related to NCDs was conducted, and data were extracted using a piloted data extraction proforma adapted from the Joanna Briggs Institute tool. Meta-analysis was performed using Stata 16. While the pooled prevalence of Diabetes Mellitus (DM) and undiagnosed (DM) was computed and presented using forest plots, then overall prevalence of NCDs and other various types of NCDs were narratively synthesized. I 2 was used to assess heterogeneity. Studies that did not fulfill the criteria (used similar tool to measure the types of NCDs) for meta-analysis were narratively synthesized.ResultsTwenty-two studies met the inclusion criteria. Five studies measured the prevalence of NCDs (all NCDs together), ranging from 29 to 35% (prevalence estimates not pooled). The pooled prevalence of Diabetes Mellitus (DM) across ten studies was 5% (95% CI: 4-7%). Three studies each reported on the prevalence of undiagnosed DM (pooled prevalence 5%, 95% CI: 4-7%) and pre-DM (pooled prevalence 7%, 95% CI: 3-14%%). In a narrative analysis the prevalence of cardiovascular conditions ranged from 13.4 to 32.2% (n = 3 studies), cancer mortality ranged from 4 to 18% (n = 3 studies) and respiratory conditions ranged from 1 to 18% (n = 3 studies). Some studies have determined more than one NCDs and that is why the total number of studies are exceeding more than twenty studies.Conclusion and recommendationsOur analysis found that approximately one-third of Ethiopians have an NCD, with cardiovascular diseases the most common of all NCDs. The prevalence of respiratory conditions also appears high, but there are insufficient data for a pooled estimate. Whilst the prevalence of DM appears relatively low, there is evidence that the magnitude is increasing. Public health actions to address the high burden of cardiovascular and respiratory diseases, as well as the increasing magnitude of DM in Ethiopia, must be prioritized.Systematic review registrationPROSPERO [CRD42020196815].
