M-A | Long-term consumption of 10 food groups and cardiovascular mortality
7 Mar, 2023 | 12:58h | UTCSummary:
This systematic review and meta-analysis of 22 prospective cohort studies evaluated the association between the consumption of 10 food groups and cardiovascular mortality.
The researchers found that a long-term high intake of whole grains, fruits and vegetables, and nuts was associated with reduced cardiovascular mortality, while a high intake of red/processed meat was associated with increased risk. On the other hand, the consumption of dairy products and legumes did not show a significant association with cardiovascular risk.
The researchers acknowledge the limitations of observational studies and the need for further research on the long-term effects of specific food groups on cardiovascular mortality.

Artificial sweetener erythritol possibly implicated in increased cardiovascular risk
1 Mar, 2023 | 14:08h | UTCSummary: A recent study published in Nature Medicine found that erythritol, a popular artificial sweetener, is possibly implicated with an increased risk of major adverse cardiovascular events (MACE) such as heart attack and stroke. Analyzing data from over 4,000 people in the US and Europe, the researchers found that those with higher blood erythritol levels were at a greater risk of MACE. The researchers also examined the effects of adding erythritol to whole blood or isolated platelets and found that it made platelets easier to activate and form clots. In addition, a pilot intervention study with healthy volunteers showed that erythritol ingestion led to a marked and sustained increase in plasma erythritol levels above those associated with heightened platelet reactivity and thrombosis potential. The authors note that further studies are needed to confirm their findings and assess the long-term safety of erythritol.

M-A | Combination of multiple low-risk lifestyle behaviors and incident type 2 diabetes
1 Mar, 2023 | 14:06h | UTCSummary: This systematic review and meta-analysis assessed the association between multiple low-risk lifestyle behaviors (LRLBs) and the incidence of type 2 diabetes. The study examined 30 cohort comparisons involving 1,693,753 participants and 75,669 cases of type 2 diabetes. The LRLBs evaluated in the study were maintaining a healthy body weight, healthy diet, regular exercise, smoking abstinence or cessation, and light alcohol consumption. Results showed that the highest adherence to these LRLBs was associated with an 80% lower risk of type 2 diabetes compared to the lowest adherence group. Thus, targeting these LRLBs could be an effective strategy for the primary prevention of type 2 diabetes. However, the authors recommend promoting only four LRLBs, excluding alcohol intake, due to its association with increased harm. The potential benefits of small alcohol intake remain a controversial issue since most studies on the subject are observational and subject to residual confounding.

[Not published yet] M-A | Too little sodium can be harmful to heart failure patients
24 Feb, 2023 | 13:59h | UTCSummary: New research presented at the American College of Cardiology’s annual scientific session suggests that heart failure patients restricting their dietary sodium intake to levels below the standard recommended maximum of 2.3 grams per day do not have additional benefits and may be at increased risk of death. The study analyzed nine randomized controlled trials that assessed different levels of sodium restriction and found that patients following a diet with a sodium intake target below 2.5 grams per day were 80% more likely to die than those following a diet with a target of 2.5 grams per day or more. The researchers recommend establishing a safe level of sodium consumption instead of overly restricting sodium.

M-A | Efficacy of elimination diets in eosinophilic esophagitis
24 Feb, 2023 | 13:47h | UTCSummary: This systematic review and meta-analysis evaluated the effectiveness of various dietary treatment regimens for eosinophilic esophagitis (EoE). After analyzing 34 studies with 1762 patients, it was concluded that dietary therapy is a viable and efficacious option for individuals with EoE of all ages, with an overall histological remission rate of 53.8% and a clinical response rate of 80.8%. The study also found that highly restrictive dietary regimes, such as a six-food elimination diet, may not be superior to less restrictive dietary regimens, such as a four-food elimination diet or one-food elimination diet, in achieving histological remission, supporting less restrictive dietary regimens as a treatment option. The study has several limitations, such as the observational nature of most studies included.

SR | Antenatal dietary supplementation with myo‐inositol for preventing gestational diabetes
24 Feb, 2023 | 13:45h | UTCSummary: The article discusses the effectiveness of myo-inositol, a naturally occurring sugar, as a dietary supplement for preventing gestational diabetes in pregnant women. The review included seven randomized controlled trials, with a total of 1319 women who were 10 to 24 weeks pregnant at the start of the studies. The results showed that myo-inositol may reduce the incidence of gestational diabetes, hypertensive disorders of pregnancy, and preterm birth, but there was limited data on other outcomes, such as perinatal mortality and serious infant morbidity. The certainty of the evidence was low to very low due to small sample sizes, inconsistency in doses and timing of administration, and lack of data from diverse populations. The authors suggest that further well-designed studies are needed to assess the effectiveness of myo-inositol in preventing gestational diabetes and improving other health outcomes for mothers and their babies.
Cohort Study | Heavy coffee intake is associated with kidney disfunction in genetically predisposed individuals
24 Feb, 2023 | 13:42h | UTCSummary: The study investigated whether a person’s genetic variation in the enzyme that metabolizes caffeine, called CYP1A2, modifies the association between coffee intake and kidney dysfunction. The study was conducted on 1180 participants with stage 1 hypertension. Data were collected from April 1, 1990, to June 30, 2006, with a follow-up of approximately 10 years. The study found that consuming more than three cups of coffee per day was associated with increased risks of albuminuria, hyperfiltration, and hypertension only among slow metabolizers of caffeine. The findings suggest that caffeine may play a role in the development of kidney disease in genetically susceptible individuals, but further studies are required to confirm these findings.

M-A | Disordered eating affects 1 in 5 children and adolescents
23 Feb, 2023 | 13:33h | UTCSummary: The text reports the findings of a systematic review and meta-analysis that included 32 studies on the global proportion of disordered eating in children and adolescents aged 6 to 18 years, assessed with the SCOFF questionnaire, a widely used screening measure for eating disorders. The review found that approximately 22% of children and adolescents showed disordered eating, which was higher among girls, older adolescents, and those with higher body mass index. The high figures are concerning from a public health perspective and highlight the need for prevention strategies to address disordered eating. The study has limitations, including the cross-sectional nature of most of the included studies and the use of self-report questionnaires to assess disordered eating, which may be subject to bias.

RCT | Effect of alternate day fasting combined with aerobic exercise on non-alcoholic fatty liver disease
20 Feb, 2023 | 12:27h | UTCSummary: The article reports on a randomized trial that compared the effects of alternate-day fasting (ADF) combined with exercise, fasting alone, or exercise alone in adults with obesity and non-alcoholic fatty liver disease (NAFLD). After three months, the combination of ADF and exercise significantly reduced intrahepatic triglyceride content, body weight, fat mass, waist circumference, and alanine transaminase levels compared to the control group. The intervention seems promising for patients with fatty liver disease who want to improve their health without using medications.

ESPEN practical guideline | Home parenteral nutrition
20 Feb, 2023 | 12:21h | UTCSummary: Home parenteral nutrition (HPN) is a form of nutrition support where a patient receives intravenous nutrition at home. It is used for patients who cannot receive adequate nutrition through oral or enteral routes, such as those with intestinal failure, severe inflammatory bowel disease, or other gastrointestinal disorders. HPN can be a life-saving therapy, but it requires careful patient selection, as well as ongoing monitoring and management by a multidisciplinary team. The ESPEN guideline aims to provide practical guidance on the use of HPN, including the nutritional and metabolic aspects of care and the practical considerations of administering HPN at home. The guideline also emphasizes the importance of patient-centered care and shared decision-making, highlighting the need for regular assessment and monitoring of patients.

M-A | Soluble fiber supplementation and serum lipid profile
20 Feb, 2023 | 12:18h | UTCSummary: The article presents the results of a systematic review and dose-response meta-analysis of randomized controlled trials (RCTs) that evaluated the effect of soluble fiber supplementation on blood lipid parameters in adults. The review included 181 RCTs with 220 treatment arms and 14,505 participants. The meta-analysis found that soluble fiber supplementation significantly reduced LDL cholesterol, total cholesterol, triglycerides, and apolipoprotein B concentrations. The article suggests that increasing fiber intake using soluble fiber supplementation could be an effective intervention in the prevention and management of dyslipidemia, and consequently may contribute to the risk reduction of cardiovascular diseases. However, the article also notes that because of the high between-study heterogeneity and publication bias, the findings should be interpreted cautiously.
RCT | Orlistat and a low-carb diet show promising results for the treatment of Metabolic-Associated Fatty Liver Disease
16 Feb, 2023 | 15:07h | UTCSummary: The study aimed to compare the effects of orlistat or a high-protein/lower-carbohydrate diet with a control diet in Asian patients with obesity and metabolic-associated fatty liver disease (MAFLD) over 24 weeks. The primary endpoint was the relative change in liver fat content (LFC) assessed by MRI-PDFF. A total of 118 patients were randomly assigned to the control group, orlistat group, or experimental diet group. All three groups demonstrated improvement in liver steatosis at week 24, with the orlistat group and the experimental diet group both showing a significant decrease in LFC compared to the control group.*

Cohort Study | Associations between types and sources of dietary carbohydrates and cardiovascular disease risk
15 Feb, 2023 | 16:13h | UTCSummary: This study found that the associations between carbohydrate intake and cardiovascular disease risk depend on the type and source of carbohydrates consumed, with free sugar intake being associated with higher risk of total cardiovascular disease and stroke. Fiber intake was associated with lower risk, and replacing refined grain starch and free sugars with wholegrain starch and non-free sugars may be protective for cardiovascular disease. Free sugar intake was also associated with higher triglycerides and lipoprotein subclasses. As with all observational studies, this study cannot establish causality, but rather suggests associations between carbohydrate intake and cardiovascular disease risk, and the importance of considering the quality of carbohydrates consumed for cardiovascular health.*

Study suggests long-term caloric restriction could slow biological aging in healthy adults
14 Feb, 2023 | 10:52h | UTCSummary: The article reports the results of a study that analyzed the impact of caloric restriction (CR), defined as reducing caloric intake without depriving essential nutrients, on DNA methylation, a measure of aging, in blood samples from the Comprehensive Assessment of Long-term Effects of Reducing Intake of Energy (CALERIE) trial. The results showed that the CALERIE intervention slowed the pace of aging, as measured by the DunedinPACE DNAm algorithm, but did not lead to significant changes in biological age estimates measured by various DNAm clocks. The authors note that while treatment effect sizes were small, a modest slowing of the pace of aging can have a significant impact on population health. They also highlight the need for further trials with long-term follow-up to establish the effects of interventions on primary healthy-aging endpoints, including the incidence of chronic disease and mortality.
