Effect of honey on cardiometabolic risk factors: a systematic review and meta-analysis.

CONTEXT: Excess calories from free sugars are implicated in the epidemics of obesity and type 2 diabetes. Honey is a free sugar but is generally regarded as healthy. OBJECTIVE: The effect of honey on cardiometabolic risk factors was assessed via a systematic review and meta-analysis of controlled trials using the GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) approach. DATA SOURCES: MEDLINE, Embase, and the Cochrane Library databases were searched up to January 4, 2021, for controlled trials ≥1 week in duration that assessed the effect of oral honey intake on adiposity, glycemic control, lipids, blood pressure, uric acid, inflammatory markers, and markers of nonalcoholic fatty liver disease. DATA EXTRACTION: Independent reviewers extracted data and assessed risk of bias. Data were pooled using the inverse variance method and expressed as mean differences (MDs) with 95%CIs. Certainty of evidence was assessed using GRADE. DATA ANALYSIS: A total of 18 controlled trials (33 trial comparisons, N = 1105 participants) were included. Overall, honey reduced fasting glucose (MD = -0.20 mmol/L, 95%CI, -0.37 to -0.04 mmol/L; low certainty of evidence), total cholesterol (MD = -0.18 mmol/L, 95%CI, -0.33 to -0.04 mmol/L; low certainty), low-density lipoprotein cholesterol (MD = -0.16 mmol/L, 95%CI, -0.30 to -0.02 mmol/L; low certainty), fasting triglycerides (MD = -0.13 mmol/L, 95%CI, -0.20 to -0.07 mmol/L; low certainty), and alanine aminotransferase (MD = -9.75 U/L, 95%CI, -18.29 to -1.21 U/L; low certainty) and increased high-density lipoprotein cholesterol (MD = 0.07 mmol/L, 95%CI, 0.04-0.10 mmol/L; high certainty). There were significant subgroup differences by floral source and by honey processing, with robinia honey, clover honey, and raw honey showing beneficial effects on fasting glucose and total cholesterol. CONCLUSION: Honey, especially robinia, clover, and unprocessed raw honey, may improve glycemic control and lipid levels when consumed within a healthy dietary pattern. More studies focusing on the floral source and the processing of honey are required to increase certainty of the evidence.

Effect of Total Starch and Resistant Starch in Commercial Extruded Dog Foods on Gastric Emptying in Siberian Huskies.

Gastric emptying rate (GER) may impact diabetes and obesity in humans and could provide a method to reduce canine weight gain. Starch, the most common source of carbohydrates (CHOs) in pet food, is classified as rapidly or slowly digestible, or resistant to digestion. This study investigated starch source effects in commercial extruded dog foods on the GER of 11 healthy adult Siberian Huskies. Test diets were classified as traditional, grain-free, whole-grain, and vegan. Dogs received each diet once, a glucose control twice, and acetaminophen (Ac) as a marker for GER in a randomized, partially replicated, 6 × 6 Latin square design. Pre- and post-prandial blood samples were collected at 16 timepoints from -15 to 480 min. Serum Ac concentrations were assessed via standard spectrophotometric assays and fitted with a mathematical model to estimate parameters of GER. Parameter values were subjected to ANOVA, with period and treatment as fixed effects and dog as a random effect. More total emptying (p = 0.074) occurred at a faster rate (p = 0.028) in dogs fed the grain-free diet, which contained the lowest total starch (34.03 ± 0.23%) and highest resistant starch (0.52 ± 0.007%). This research may benefit future diet formulations to reduce the prevalence of canine weight gain.

The Role of Pulses in the Dietary Management of Diabetes.

Pulses are highly nutritious foods that are included as part of Canada's Food Guide to promote healthful eating, and they have established health benefits that can contribute to the dietary management of diabetes. A review of studies that have examined the effects of pulse consumption on health outcomes, integral to the management of diabetes, provides credible evidence for improvements in glycemic control, reduction of blood lipids and regulation of body weight. Results from acute feeding trials suggest that postprandial blood glucose response is significantly attenuated by a single pulse serving of between three-quarters and 1 cup. At lower doses, pulses attenuate postprandial blood glucose response more than similar amounts of starchy foods. Long-term pulse consumption of 5 cups per week appears to result consistently in improvements in glycemic control. There is high-quality evidence that supports a role for pulse consumption in the reduction of risk for cardiovascular disease; this provides a sound rationale for the regular incorporation of pulses at about two-thirds of a cup daily in the management of hyperlipidemia in persons with type 2 diabetes. Pulse consumption can contribute to improving satiety, reducing food intake and regulating body weight, which can reduce obesity risk and, in turn, improve diabetes management. Collectively, available evidence provides very good support for a role of regular pulse consumption in the prevention and management of diabetes.

Barriers and facilitators to establishing a national public health observatory / Barreras y facilitadores para el establecimiento de un observatorio de salud pública nacional

OBJECTIVE: To determine what stakeholders perceive as barriers and facilitators to creating a national public health observatory (PHO) in Trinidad and Tobago. METHODS: A descriptive study was conducted based on 15 key informant interviews carried out from April to September 2013. The key informants worked within the health care sector in Trinidad and Tobago. Using a semi-structured interview guide, information was collected on knowledge, attitudes, and beliefs about creating a PHO; barriers and facilitators to creating and sustaining a PHO; legal considerations; and human resource and information technology requirements. Common themes of the responses were identified. RESULTS: The majority of participants supported the development of a national PHO, recognized its value in informing their work, and indicated that a national PHO could 1) provide information to support evidence-informed decision-making for health policy and strategic planning; 2) facilitate data management by establishing data policies, procedures, and standards; 3) increase the use of data by synthesizing and disseminating information; and 4) provide data for benchmarking. However, a number of barriers were identified, including 1) the perception that data collection is not valued; 2) untimely availability of data; 3) limited data synthesis, dissemination, and utilization to inform decision-making; and 4) challenges related to the allocation of human resources and existing information technology. CONCLUSIONS: Key informants support the development of a national PHO in Trinidad and Tobago. The findings align well within the components of the conceptual framework for establishing national health observatories. A stepwise approach to establishing a national PHO in Trinidad and Tobago, beginning with structural components and followed by functional components, is recommended. A national PHO in Trinidad and Tobago could serve as a model for other countries in the Caribbean.

Dietary analysis of randomly selected meals from the Child Hunger and Education Program School Nutrition Program in Saskatchewan, Canada, suggests that nutrient target levels are being provided.

In Canada, school meals are regarded as important for social, educational, and nutritional reasons and have been provided for several years because of concerns about the health and welfare of children, especially those from low-income households. They are generally offered as local community organization and individual schools, are not regulated by law, and have no set national nutrition standards. The Canadian scientific literature lacks quantitative information on the nutritional adequacy of school meals. Better and more evaluation of such programs would encourage and guide administrators to assess other local programs in a similar fashion. Here, we describe the dietary assessment process of 1 school meal program in Canada and the nutritional adequacy of the meals. Throughout 10 years (1997-2007), the contents of 159 lunches and 90 breakfasts were collected mainly from elementary schools participating in the Child Hunger and Education Program Good Food, Inc's school nutrition program initiative in Saskatoon, Saskatchewan, Canada. We collected, weighed, and analyzed food samples from meals served to children at participating schools. We then compared their nutrient content against standards based on the Dietary Recommended Intakes for children aged 4 to 8 and 9 to 13 years using one third of the recommendations as the standard for lunches and one fourth for breakfasts. Overall, both meals had a good nutrient profile and met the standards for most analyzed macronutrients and micronutrients throughout the years. Although energy was persistently low, vitamin and mineral contents were often above the standards, reflecting a tendency to offer nutrient-dense foods in lieu of energy-dense foods. The rigorous methodology described in this manuscript can be followed to assess other small local programs. Furthermore, the dietary assessment presented can encourage not only the implementation of school meal programs in other locations but also the assessment of already existing programs-a clear need in the scientific literature.

Risk factors preceding type 2 diabetes and cardiomyopathy.

Type 2 diabetes (T2DM) and its complications such as cardiomyopathy, contribute significantly to morbidity and mortality worldwide. Increased adoption of westernized diets and decreased physical activity are contributing to the obesity epidemic which, in turn, increases the risk for T2DM. Other risk factors for T2DM include insulin resistance, dyslipidemia, hypertension, metabolic syndrome, and a genetic predisposition. Risk measures for assessing these factors include family history, blood pressure, body weight, waist circumference, fasting glucose, insulin, and lipid levels, and calculated indices such as BMI, HOMA, and QUIKI. Most of these risk measures routinely done in annual check-ups, should help a primary care physician in making an early diagnosis of impending diabetic condition. The underlying mechanisms of these clinical, anthropometric and biochemical risk measures may also be involved in the etiology of diabetes and its complications. Their levels and changes over time therefore, may indeed reflect the disease process. Early and continued assessment of diabetes risk, as part of patient care, will help identify individuals most likely to develop diabetes and allow for early interventions to reduce risk factors as well as delay or may even prevent disease onset. In T2DM patients, ongoing measurement of risk markers and implementation of intervention where appropriate will improve the diabetic condition, decrease risk of cardiovascular and other complications, and decrease morbidity.

SNP haplotypes and allele frequencies show evidence for disruptive and balancing selection in the human leukocyte receptor complex.

The human leukocyte receptor complex (LRC) of Chromosome 19q13.4 encodes polymorphic and highly homologous genes that are expressed by cells of the immune system and regulate their function. There is an enormous diversity at the LRC, most particularly the variable number of killer cell immunoglobulin-like receptor (KIR) genes. KIR have been associated with several disease processes due to their interaction with polymorphic human leukocyte antigen class I molecules. We have assessed haplotype compositions, linkage disequilibrium patterns and allele frequencies in two Caucasoid population samples (n=54, n=100), using a composite of single-nucleotide polymorphism (SNP) markers and high-resolution, allele-specific molecular genotyping. Particular KIR loci segregated with SNP and other markers, forming two blocks that were separated by a region with a greater history of recombination. The KIR haplotype composition and allele frequency distributions were consistent with KIR having been subject to balancing selection (Watterson's F: P=0.001). In contrast, there was a high inter - population heterogeneity measure for the LRC-encoded leukocyte immunoglobulin-like receptor A3 (LILRA3), indicating pathogen-driven disruptive selection (Wright's FST=0.32). An assessment of seven populations representative of African, Asian and Caucasoid ethnic groups (total n=593) provided little evidence for long-range LRC haplotypes. The different natural selection pressures acting on each locus may have contributed to a lack of linkage disequilibrium between them.

Glyoxalase I activity in erythrocytes from severely malnourished children

The enzyme glycoxalase I (glyox I) is involved in metabolic detoxification, and requires glutathione (GSH) as a cofactor. Given the low concentration of whole blood GSH in children with oedematous malnutrition, it is possible that the function of this pathway may be compromised in these children. Glyox I activity was therfore assayed in erythocytes taken from 133 severely malnourished children and 21 age-matched controls. The mean values (ñSEM) for the marasmic group (marasmus: 105 ñ 4/u/gm Hb) and the group with kwashiorkor (Kwash: 103 ñ 4/u/gm Hb) were not significantly different from controls (cont: 104 ñ 2u/gm HB)>. In the group with marasmic-kwashiorkor (M-K: 88 ñ 4u/g Hb) Glyox I activity was significantly lower in controls (p < 0.005), as well as in children with marasmus (p < 0.005), and kwashiorkor (p < 0.05). Enzyme activity was lower than normal in 45 per cent of the MK group. Seven children died subsequent to admission; in five cases Glyox I activities were exceedingly low. There was a weak positive correlation between Glyox I activity and whole blood levels of GSH (r=0.215). We conclude that Glyox I activity is relatively unaffected in malnutrition, except in those with M-K and especially those who do not survive the acutely malnourished state
