Personalized nutrition education at a grocery store improves adherence to DASH diet

“The Supermarket and Web-based Intervention Targeting Nutrition (SuperWIN) Trial, a partnership between academic researchers and the grocery retailer Kroger, is the first to deliver a nutritional intervention in each participant's home grocery store guided by their personal food purchasing data. Comparing participants' eating habits at the start of the study and three months later, in-store nutrition education sessions significantly increased DASH adherence scores by 4.7 points on top of an enhanced standard of care group, which increased DASH scores by a baseline amount of 5.8 points alone. Combining in-store nutrition education sessions with online tools and training increased DASH scores by an additional 3.8 points compared to the nutrition education sessions without the online resources”.

Metabolomic and microbiome profiling reveals personalized risk factors for coronary artery disease

This study "analyzed the gut microbiota and the blood levels of bacterial-derived compounds in hundreds of people [from two major Israeli hospitals], including healthy individuals, people with obesity and type 2 diabetes but without a diagnosis of heart disease, and those who had heart conditions". The findings showed that "alterations of the gut microbiota are already present in people with obesity and type 2 diabetes, long before the onset of heart disease symptoms. People with heart disease showed specific alterations, including fewer types of bacteria producing beneficial molecules and more bacteria producing unhealthy compounds". In conclusion: "The gut microbiota changes can happen in the very early stages of heart disease. The microbial and metabolic profiles identified could be used as markers of the transition towards heart disease".

 

Unraveling disease pathways involving the gut microbiota: the need for deep phenotyping and longitudinal data

“Diet is a major component of primary prevention of cardiometabolic disease, although much remains unknown about precise pathways through which diet exerts its effects. Diet is intimately connected to the gut microbiota, influencing microbial composition and function through the delivery of nutrients. In addition, the production of many health-related metabolites of dietary components relies, in part, on the gut microbiota (1). The potential for diet, a modifiable behavior, to influence the gut microbiota may have important implications for cardiometabolic health. A large and growing body of animal and human studies support the role of the gut microbiota in cardiometabolic outcomes (2), with particular evidence for inflammation-related pathways (3). Together, there is strong logic in a potential for the gut microbiota to mediate dietary effects on cardiometabolic outcomes.”

 

Repercussions of intermittent fasting on the intestinal microbiota community and body composition: a systematic review

“The aim of this study was to provide the reader with a current survey of intermittent fasting (IF) protocols and an understanding of the outcomes found to date in terms of the profile of the intestinal microbiota (IM) in obese organisms. Of the 82 original articles identified from the databases, 35 were eliminated due to duplication, and 32 were excluded due to not meeting the inclusion criteria. Two additional articles found in a new search were added, yielding a total of 17 studies to be included in this review. Among the protocols, alternate-day fasting (ADF) and time-restricted feeding (TRF) were the most common, and they were shown to have different mechanisms of metabolic signaling. In short, the ADF and TRF protocols have a positive effect on the remodeling of the IM and can possibly be used to control body adiposity, improve insulin sensitivity, and achieve other obesity-related metabolic changes.”

 

Serum folate deficiency and the risks of dementia and all-cause mortality: a national study of old age

This study aimed "to examine the associations between serum folate deficiency and the risks of incident dementia and all-cause mortality in a large national sample of older adults" (n=27 188). Serum folate deficiency was classified as present (<4.4 ng/mL), otherwise absent. The study results show that "The presence compared with the absence of serum folate deficiency was associated with higher risks of dementia and all-cause mortality".

 

A Guide to Dietary Pattern–Microbiome Data Integration

This study aims to examine the intake and plasma/serum levels of micronutrients in IBS and whether these factors were associated with symptoms and restrictions, and to study the effects of starch- and sucrose-reduced diet (SSRD). The protocol of SSRD diet or control has been performed over 4 weeks in 105 patients with IBS. The results show "(1) Extraintestinal symptoms and fatigue inversely associated with intake of vitamin B6, phosphorus, magnesium, and iodine. (2) Fatigue was also inversely associated with calcium, iron, and zinc intakes. (3) Plasma ferritin was lower in participants on restrictions. (4) SSRD increased the intake of several vitamins, selenium, and fat, whereas sodium intake was decreased, with markedly reduced symptoms".

 

Scientists develop coated probiotics that could be effectively delivered into the human gut

"Scientists at Nanyang Technological University, Singapore (NTU Singapore) have developed probiotics with a unique edible coating that ensures the beneficial bacteria successfully reach the intestine once they are ingested. (...) In the NTU-study, the probiotics, gut-friendly Lacticaseibacillus bacteria, are spray-coated with alginate, a carbohydrate derived from brown algae, protecting them from the harsh acidic conditions in the stomach. Through experiments simulating a journey along the human digestive tract, only the probiotics with the NTU-developed coating survived.”

 

Associations between dietary patterns, FTO genotype, and obesity in adults from seven European countries

This study was performed on 1280 adults from seven European countries and aimed "to derive dietary patterns based on intake of discretionary foods, saturated fatty acids (SFA), and fibre, and examine cross-sectional associations with BMI and waist circumference (WC), and interaction effects of FTO genotype". The results suggest that "consuming a dietary pattern low in discretionary foods and high-SFA and low-fibre foods is likely to be important for maintaining a healthy weight, regardless of FTO predisposition to obesity".

 

Changes in Blood Lipid Levels After a Digitally Enabled Cardiometabolic Preventive Health Program: Pre-Post Study in an Adult Dutch General Population Cohort

This observational study aimed to determine how the levels of lipids, namely total cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, non-HDL cholesterol, and triglycerides, changed over time in a Dutch general population cohort (n=348) undergoing a digital preventive health program (Ancora Health between January 2020 and October 2021). The results show that 104 participants were advised to follow a cardiometabolic health–focused intervention. After 9 months of intervention 57% (17/30), 61% (19/31), 56% (15/27), 82% (9/11), and 100% (8/8) showed improvements at remeasurement for total cholesterol (by 0.5 mmol/L (- 7.5%), LDL (by 0.39 mmol/L (- 10.0%), HDL ( increased by 0.17 mmol/L (+ 15.6%), and non-HDL cholesterol (by 0.44 mmol/L (- 8.3%), and triglycerides (by 0.97 mmol/L (- 32.0%), respectively.

Digital therapeutics care utilizing genetics and gut microbiome signals for the management of functional gastrointestinal disorder and From a Preliminary Retrospective Study

The aim of this study was to assess how effective a digital therapeutics intervention personalized [Digbi Health] on genomic SNPs and gut microbiome signals were at reducing symptomatology of FGIDs (functional gastrointestinal disorders) in individuals that successfully lost body weight. The sample used was a cohort of 177 adults who reached 5% or more weight loss on the Digbi Health personalized digital care program. The results show that Digbi Health "reduced the summative severity of symptoms for 89.42% (93/104) of users who reported FGIDs. Reduction in summative FGID symptom severity and IBS symptom severity were best modeled by a mixture of genomic and microbiome predictors, whereas reduction in diarrhea and constipation symptom severity were best modeled by microbiome predictors only".
