Abstract

Purpose

Flours obtained from pulps and peels of unripe banana were evaluated regarding their chemical composition and glycemic responses in rats. Moreover, this study aims to propose a new assay to measure glycemic responses using animals.

Design/methodology/approach

Proximal composition, total dietary fiber and its insoluble and soluble fractions, mineral content and tannins were evaluated. Glycemic responses were measured using albino Wistar rats (seven animals/group).

Findings

Flours from pulp and peel of unripe banana presented high content of carbohydrates and minerals. Moreover, flour from peel was rich in insoluble fiber, whereas flour from pulp had adequate proportion of insoluble and soluble fractions. Consumption of banana flours from peel and pulp did not affect fasting blood glucose of normoglycemic rats. Flour from pulp, when consumed in concentrations of 10 and 15 per cent of the diet, significantly stimulated lower glycemic responses in the animals.

Originality/value

Results presented in this study disclose unripe banana flour as an interesting food source, which may be indicated for preventing some types of diseases, such as diabetes, obesity and dyslipidemia. Moreover, the glycemic index assay using animals promoted accurate answers, as the diets were standardized, unlike studies with humans, which do not control variations related to omission and distortion of information regarding food intake.

Abstract

The Public Library was a grim, unattractive‐looking building. Smoke‐blackened and austere, it stood at the junction of two busy thoroughfares, with no outward manifestation of its identity apart from the almost obscured and somehow distasteful words “Free Library”, carved in stone over its portals. It was a repulsive structure, and for a moment or two I was conscious of the forbidding atmosphere which it seemed to radiate. But the town, which I was visiting for business reasons, offered few other attractions. I had dealt half‐heartedly with an un‐imaginative meal, and had a little time to spare. A post‐prandial browse among books seemed to be the only consolation available. Shaking off a feeling of repugnance, I stepped through the swing doors into the dim fastnesses of the interior.

Abstract

Purpose

The purpose of this study is to collect and assess the evidence available on the effect of non nutritive sweeteners on appetite, weight and glycemic regulation. As a replacement for sugars, non-nutritive sweeteners (NNSs) are widely being used in different food products with the assumption that these would lower calorie intake and help to manage weight and blood sugar levels better. However, studies using animal models have reported that chronic exposure to NNSs leads to increased food consumption, weight gain and insulin resistance.

Design/methodology/approach

Evidence was acquired from systematic reviews or meta-analyses (2016–2021) of relevant clinical studies, especially randomized control trials using Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines.

Findings

The review showed NNSs exposure did not conclusively induce increased food intake or change in subjective appetite ratings. Appetite biomarkers like ghrelin, gastric inhibitory peptide, C-peptide levels and Peptide YY remained mostly unaffected by NNSs. Meta-analyses of human randomized control studies showed a reduced energy intake and body weight. No significant change was seen in blood glucose levels, post-prandial glycemic or insulin response after consumption of NNSs. Adequate evidence is not available to conclusively say that NNSs influence gut health at doses relevant to human use.

Research limitations/implications

Most studies which are prospective cohort, observational and cross-sectional studies suggest that use of NNSs may promote obesity and metabolic syndrome in adults. Such studies are plagued by confounding variables and reverse causation. Mechanistic evidence is mostly based on in-vitro and in-vivo studies. The same causal pathways may not be operative or relevant in humans.

Practical implications

This review of available literature concludes that to achieve specific public health and clinical goals, the safe use of NNSs for the reduction of intakes of free sugars and energy should be explored. This would be possible by educating the consumer about energy compensation and understanding the nutritional content of artificially sweetened products in terms of calories coming from fat and complex carbohydrates used in the product.

Originality/value

This study was, thus, designed with the objective of examining the usefulness of NNSs in human population, especially with respect to insulin regulation, glycemic control and weight management. Well-designed randomized control trials which control for confounding variables are needed to generate high quality evidence.

Abstract

Purpose

The purpose of this paper is to review a case of a man with intellectual disability, autism and challenging behaviour who presented with vomiting, regurgitations and significant weight loss.

Design/methodology/approach

The paper examines the case history and identifies challenges contributing to symptom classification and management of a patient with intractable vomiting, regurgitations and significant weight loss.

Findings

This case illustrates the importance of the multidisciplinary team working required to reduce morbidity and risk of mortality, as well as highlighting some of the challenges associated with coordinating different approaches from different agencies. Pharmacological management did not result in lasting symptom resolution in this case. Difficulties in establishing diagnostic certainty and consideration of whether symptoms could be consistent with rumination syndrome are also discussed. The value of consistent implementation of positive behavioural support is also demonstrated.

Originality/value

The rapid and dangerous weight loss described in this case is associated with adverse physical health outcomes and has generated significant anxiety resulting in extensive liaison between primary and secondary mental and physical health services. Additionally, it considers whether the symptoms could be attributed to the relatively rare diagnosis of rumination syndrome which is historically underdiagnosed.

Abstract

Purpose

This study aims to evaluate the effect of probiotic provitamin A cassava hydrolysate with Lactobacillus rhamnosus GG (hLGG) on weight and lipid profile of Wistar rats and its glycemic index using Wistar rats and human subjects.

Design/methodology/approach

Adult male Wistar rats (n = 40, 120–150 g) were orally administered provitamin A cassava hydrolysate with 1 × 1010, 2 × 1010 and 4 × 1010 CFU/g encapsulated or CFU/mL free Lactobacillus rhamnosus GG for 30 days, during which weight and lipid profile of rats were monitored. Blood glucose levels of rats and human subjects were also measured in Oral Glucose Tolerance Test to determine the Glycemic indices of hLGG.

Findings

Rats administered the highest doses of free or encapsulated hLGG [(4 × 1010 CFU) (PHE4 and PHF4, respectively)] had the lowest (18.2 ± 0.7 and 8.0 ± 0.6%, respectively, p < 0.001) percentage body weight gain compared to control (40 ± 0.6%). Lowest cholesterol and triglyceride (42.4 ± 0.5 and 44.4 ± 0.7 g/dL, p < 0.001, respectively) were observed in rats administered PHE4, with the lowest plasma glucose concentrations in PHE4 and PHF4 groups (43 ± 1 and 49 ± 0.7 g/dL, p < 0.001, respectively). Oral Glucose Tolerance Test for rats and human subjects showed lower peak blood glucose levels and glycemic indices in hLGG groups compared to controls in a dose-dependent manner.

Originality/value

Consumption of soft drinks, which supply non-nutritive energy, may lead to degenerative metabolic disorders such as obesity and diabetes. Beverages with probiotics such as Lactobacillus rhamnosus GG, on the other hand, offer a positive weight management approach. Development of non-dairy beverages such as provitamin A cassava hLGG is ongoing. Provitamin A cassava hLGG showed its ability to control weight gain, blood glucose levels and serum lipids. Thus, the beverage can be consumed as a healthy alternative to soft drinks and for weight management.

Abstract

Purpose

The aims of this study are to assess the prevalence and timings of heartburn symptoms in a Sri Lankan population living in the UK and to identify diet and lifestyle symptom triggers.

Design/methodology/approach

A total of 60 Sri Lankan adults, aged between 18 and 66 years completed a background questionnaire and a nine‐item gastro‐oesophageal reflux disease (GORD) impact scale.

Findings

Application of the GORD impact scale verified that all participants experienced heartburn symptoms on a weekly basis. Episodes of heartburn tend to occur post‐prandially. Diet and lifestyle factors were found to trigger heartburn symptoms particularly consuming spicy foods.

Research limitations/implications

The incidence of heartburn in Sri Lankans may be due to the process of acculturation to the Western diet and lifestyle.

Originality/value

This paper shows that Sri Lankans are susceptible to symptoms of heartburn.

Abstract

Purpose

The purpose of this paper is to provide a comprehensive summary of the effect of different dietary approaches on polycystic ovary syndrome (PCOS).

Design/methodology/approach

This review represents the history of PCOS, the symptoms, diagnosis, and treatment. It also includes up‐to‐date research articles on different types of diets that have been shown some promising effects in the treatment of PCOS.

Findings

PCOS is nowadays considered the most common endocrine abnormality, with a range of 4‐12 per cent of women affected by the syndrome. It has been proven that diet, in addition to exercise and medication, plays an important role in the treatment of PCOS. The proper dietary approach for women with PCOS should focus on the PCOS symptoms and also improve weight loss, increase fertility, and decrease risks of cardiovascular diseases.

Originality/value

This paper provides accessible and comprehensive information on PCOS (since its discovery in 1935) to researchers, nutritionists, and women with PCOS who are interested in the effect of the diet on PCOS management.

Abstract

Purpose

Many foods naturally contain dietary Cr, but lost during processing and cooking. Type 2 diabetes mellitus (T2DM) has been associated with poor glycemic control and low Cr status. The objectives of the current study were to evaluate the dietary Cr intake and its relationship with diabetes risk factors in moderately obese subjects with T2DM.

Design/methodology/approach

Thirty‐six subjects (age: 26–65 years) were recruited through local advertisements. Subjects were taking stable doses of oral antidiabetic medication(s) excluding concomitant insulin. Subjects had HbA1c ≥7 per cent, persistent impaired glucose control (2 hour glucose >200 mg dL−1) and at least a one‐year history of T2DM. Demographic characteristics, blood pressure, body mass index (BMI), family and medical history were recorded. Three‐day dietary intakes were collected and evaluated for Cr and nutrient content using Nutritionist V software. Plasma glucose, circulating insulin and lipid profile were analyzed. Homeostatic model assessment insulin resistance (IR), beta cell function (BCF) and derived ratios were calculated. Morning void urinary chromium levels were also measured.

Findings

It was observed that mean dietary Cr intake of adults (30 mcg) was below the suggested recommended daily intake (RDI) of 120 mcg day−1. These estimates correspond to approximately 16.4 μg Cr per 1000 Kcals. A significant correlation was observed between dietary Cr and fasting insulin (p<0.05), total‐C (p<0.05), LDL‐C (p<0.01), triglycerides (p<0.05), BCF (p<0.05), TG/HDL‐C ratio (p<0.01), HOMA BCF (p<0.05) and with atherogenic index in plasma (p<0.05).

Originality/value

In this study, the consumption of chromium is less than the RDI. Overall the results suggest that the US diets are inadequate in the essential metal chromium. Further studies are required to explore the relationship of Cr absorption with dietary Cr intake and risk factors in T2DM.

Abstract

A highly significant action taken by the Minister of Agriculture, Fisheries and Food, reported elsewhere in this issue, could well result in important advances in surveillance and probably legislative control over enforcement of certain aspects of EEC legislation in the Member‐states. The Minister has sent an urgent request to the Commission in Brussels to dispatch inspectors to each country, including the United Kingdom, to examine and report on the standards of inspection and hygiene with detailed information on how the EEC Directive on Poultry Meat is being implemented. Information of the method of financing the cost of poultrymeat inspection in each country has ben requested. The comprehensive survey is seen as a common approach in this one field. The Minister requested that the results of the inspectors' reports should be available to him and other Member‐states.

Abstract

Illustrates how qualitative methods can illuminate social and cultural contexts which affect food choice in the domestic situation. Argues that these contexts are best uncovered by the exploratory, inductive and less structured approaches offered by qualitative methods. Describes some analytical strengths of these methods: complexity, depth, context and dynamics. Illustrates these with examples drawn from a multi‐interview study of whole family groups carried out in Edinburgh in the late 1980s. Suggests that qualitative methods are best suited to investigating the social processes and dynamics which underpin the statistical picture presented in quantitative nutritional surveys.
