The Role of the Western Diet and Oral Microbiota in Parkinson’s Disease

The type of diet not only affects the composition of the oral microflora but is also one of the more critical factors associated with an increased risk of Parkinson’s disease, PD. This study compared diet preferences and oral microbiota profiles in patients with PD vs. healthy controls. This study compared the oral microbiota composition of 59 patients with PD and 108 healthy controls (without neurodegeneration) using 16S rRNA gene amplicon sequencing. According to results, oral microbiota in patients with PD is different compared from healthy controls. In particular, decreased abundance of Proteobacteria, Pastescibacteria, and Tenercutes was observed. The oral cavity of patients with PD was characterized by the high relative abundance of bacteria from the genera Prevotella, Streptococcus, and Lactobaccillus. There were also differences in food preferences between patients with PD and healthy controls, which revealed significantly higher intake of margarine, fish, red meat, cereals products, avocado, and olives in the patients with PD relative to healthy controls. Strong positive and negative correlations between specific food products and microbial taxa were identified.

Characterization of Lacticaseibacillus rhamnosus, Levilactobacillus brevis and Lactiplantibacillus plantarum Metabolites and Evaluation of Their Antimicrobial Activity against Food Pathogens

Lactic acid bacteria (LAB) play an important role as natural food preservatives. However, the characterization of the variety of their metabolites is limited. The objective of this study was to determine the production of specific metabolites of Lacticaseibacillus rhamnosus, Levilactobacillus brevis and Lactiplantibacillus plantarum by an optimized liquid chromatography with an ultraviolet/diode detection (HPLC-UV/DAD) method and to investigate their potential antimicrobial activity against specific food pathogens. Based on the results of this study, the main metabolites detected in Levilactobacillus brevis were 103.4 μg mL−1 DL-p-Hydroxyphenyllactic acid (OH-PLA) and 2.59 μg mL−1 vanillic acid, while 216.2 μg mL−1 OH-PLA, 19.0 μg mL−1 salicylic acid, 3.7 μg mL−1 vanillic acid, 6.9 μg mL−1 ferulic acid, 4.2 μg mL−1 benzoic acid and 1.4 μg mL−1 4-Hydrocinnamic acid were identified in the Lactiplantibacillus plantarum strain and 147.6 μg mL−1 OH-PLA and 4.9 μg mL−1 ferulic acid were identified in Lacticaseibacillus rhamnosus. This study provides alternative approaches for the molecules involved in the antimicrobial activity of food microorganism fermentation. These molecules may be used as antimicrobial ingredients in the food industry instead of conventional chemical preservatives.

Vegan Egg: A Future-Proof Food Ingredient?

Vegan eggs are designed with the aim to provide a healthier and more sustainable alternative to regular eggs. The major drivers of this industry are the increasing prevalence of egg allergies, awareness towards environmental sustainability, and the shift to vegan diets. This study intends to discuss, for the first time, the vegan egg market, including their formulation, nutritional aspects, and some applications (i.e., mayonnaise and bakery products). Recreating the complete functionality of eggs using plant-based ingredients is very challenging due to the complexity of eggs. Current, but scarce, research in this field is focused on making mixtures of plant-based ingredients to fit specific food formulations. Nutritionally, providing vegan eggs with similar or higher nutritional value to that of eggs can be of relevance to attract health-conscious consumers. Claims such as clean labels, natural, vegan, animal-free, gluten-free, and/or cholesterol-free can further boost the position of vegan eggs in the market in the coming year. At present, this market is still in its infancy stages, and clear regulations of labeling, safety, and risk assessment are deemed mandatory to organize the sector, and protect consumers.

Trends in Complementary Feeding Indicators and Intake from Specific Food Groups among Children Aged 6–23 Months in Bangladesh

The present study aims to comprehensively analyse trends in complementary feeding indicators (Introduction of solid, semi-solid, and soft foods at 6–8 months (INTRO), Minimum Dietary Diversity (MDD), Minimum Meal Frequency (MMF) and Minimum Acceptable Diet (MAD)) among children aged 6–23 months in Bangladesh. The study used data from four rounds (2007, 2011, 2014, and 2017–2018) of nationally representative Bangladesh Demographic and Health Surveys (BDHSs). The Cochran–Armitage test was performed to capture the trends in complementary feeding practices and intake from specific food groups. BDHSs are periodically conducted cross-sectional surveys in all seven administrative divisions of Bangladesh. The present analysis was performed among 8116 children (1563 in 2007, 2137 in 2011, 2249 in 2014, and 2167 in 2017–2018) aged 6–23 months. Overall, a decreasing trend was observed in all the complementary feeding indicators except INTRO from 2007 to 2014, but a substantial increase in MDD, MMF and MAD was noted in 2017–2018. A statistically significant reduction in consumption from different food groups such as legumes and nuts (p < 0.001), dairy products (p = 0.001), vitamin-A-rich fruits or vegetables (p < 0.001), and other fruits and vegetables (p < 0.001) was also observed. However, a positive trend was noted in the consumption of grains/roots/tubers (p = 0.027), and meat/fish/egg (p < 0.001). After experiencing a significant decreasing trend during 2007–2014, the recent BDHS indicates improvements in all complementary feeding indicators among young children in Bangladesh, which calls for integrated, multisectoral, and multicomponent interventions to sustain this progress.

The Nutritional Profile and On-Pack Marketing of Toddler-Specific Food Products Launched in Australia between 1996 and 2020

With the food system evolving, it is not clear how the nutrition and on-pack claims of toddler foods have been impacted. Data on the trends in Australia are lacking, so we sought to determine the changes in the nutrition and on-pack claims of toddler-specific packaged foods over time. A retrospective cross-sectional analysis was conducted using the Mintel Global New Products Database. The number of toddler-specific foods increased from 1996 to 2020. Over time, a lower proportion of meals and snacks were classified as “ultra-processed”, but a higher proportion of snacks were classified as “discretionary”. Meals launched after 2014 had higher median values for energy, saturated fat, and sugar than those in earlier years. Toddler snacks launched after 2014 had lower median values for sodium, and higher median values for fat, saturated fat, and sugar than those in earlier years. The mean number of total claims per package increased over time for snacks, with an increase in unregulated claims for both meals and snacks. Public health action is needed to ensure that the retail food environment for young children is health-promoting, including stringent and clear regulations for on-pack claims, and compositional guidelines and guidance on how to reduce the number of ultra-processed foods for toddlers.

Consumer sophistication as an enhancer of innovation in the food industry: measurement development and validation

PurposeRecently, the role of consumers in firms' innovation processes has increased. Prior literature asserts that qualitative aspects of consumers serve as crucial factors shaping the even competitiveness of a specific industry. This study focuses on measuring home demand conditions that enhance local firms' innovation.Design/methodology/approachThe present study describes the development of a 12-item measure to assess consumer sophistication in the food industry. The items assess the general knowledge, experience, skills and abilities needed to purchase a specific food category. A second-order construct with three distinct first-order constructs emerged, which were termed opinion formulation, sensitivity and exposure with variety. The reliability and validity of the scale were assessed with pilot survey data using exploratory and confirmatory factor analyses. The developed measure was tested to investigate its effect on individuals' grocery buying behaviors using grocery receipt panel data from 723 consumers.FindingsThe results indicate that consumer sophistication has a positive effect on new and the variety of grocery purchases. The more sophisticated a consumer is, the more they buy new and a variety of products. The newly developed consumer sophistication measure has a variety of potential applications to predict consumers' variety-seeking and new product purchase behavior.Originality/valueThis study is the first to develop a measure for assessing demand quality, namely, consumer sophistication of a specific food product. This approach may offer insights to practitioners regarding the relevant consumer sophistication levels to target when launching a new product or service in the food industry.

Beer and Allergens

Food allergies are an important global health concern, with many countries following the World Health Organisation’s guidelines with regards to due labelling of foods and, as such, providing forewarning about the presence of potential allergens to potential consumers. While for some produce, the link to specific allergens might be very clear to most consumers, this is not the case for all produce. People with specific food-related allergies usually know what to look out for, but occasionally, unexpected allergens are present in trusted produce. Beer is known to most to contain barley, which will contain gluten-like proteins that can cause allergic reactions in some people. Similarly, beer might contain sulphites and other potential allergens traditionally associated with beers. This review aims to examine a wide range of allergens that have entered the beer production process in recent years. As a result, examples of beers that contain one or more of the 14 EU-UK listed allergens are described, different allergen regulations in different countries are emphasised and their impact explained, and a number of case studies involving allergic reactions following exposure to and the ingestion of beer are highlighted.

Defining risk reduction strategies for tourists with specific food needs: a qualitative approach

PurposeThis exploratory study aims to identify the main risk reduction strategies when individuals suffer from coeliac disease (CD) or non-coeliac gluten sensitivity (NCGS) travel. Based on Yeung and Yee's (2013; 2019) model, the paper offers a new framework for analysing the main travel risk reduction strategies for people with specific food needs. The empirical work focuses on the perspectives of different stakeholders (CD and NCGS community, restaurant managers/service providers and nutritionists).Design/methodology/approachA qualitative approach based on thematic analysis is adopted. The results of 32 semi-structured in-depth interviews reveal different stakeholders' perspectives in order to understand the various strategies.FindingsThe findings confirm the high level of consensus that the main food risk reducers are: travel information, staff training in safety assurance, legislation and risk prevention protocols. The findings also show significant limitations in the information offered by restaurants, organisations and tourist destinations and the negative repercussions on the tourist experience and the reputation on a particular destination.Practical implicationsThe results will help hospitality business managers and destination management organisations develop food risk reduction strategies to solve some of the most important food-related problems when people in this market segment travel.Originality/valueThis work contributes to the literature by providing a new framework on travel risk reduction strategies for people with specific food needs. The novelty of this research is mainly found in the study of risk reduction strategies related to the travel decision-making process for those with CD and NCGS from different perspectives.

Recent discoveries of new Elephantomyia (Diptera, Limoniidae) fossils in Baltic amber

New data on the genus Elephantomyia (Diptera: Limoniidae) from Baltic amber are presented. A new subgenus Hoffeinsonia subgen. nov. is established with one new species: Elephantomyia (Hoffeinsonia) prima sp. nov. The new subgenus is characterized by a wing at most 2.5 × as long as it is wide without a darker pattern along the veins Sc and R1, elongate Sc, straight vein R1, sharp half of vein R2+3+4 sharply arched to the upper edge of the wing, short, wide, trapezoidal d-cell and oval pterostigma. The fossil subgenus Hoffeinsonia subgen. nov. shares features with the extant subgenera Elephantomyodes and Elephantomyia. One other extinct species of Elephantomyia was discovered and described herein as E. (s. str.) christelae sp. nov. Such features as a very elongate vein R2+3+4, 2.5 × as long as the Rs easily allowing this new species to be distinguished from the other fossil representatives of the genus Elephantomyia. The taxonomic decision on Elephantomyia grata as a species placed in nominative subgenus is provided. A list and key of fossil species of Elephantomyia are given. The morphological pattern of the genus is discussed in relation to the adaptation to a specific food spectrum, coevolution with Angiospermae of the representative genus Helius known since Cretaceous and closely related to this genus representatives of the much younger genus Elephantomyia.
