Abstract

Purpose

Early colonization and balance between the beneficial and pathogenic organisms are essential for good nutrition and health. Ability of probiotic cultures to survive and colonize under the intestinal environmental condition led to their application as functional foods. The paper aims to discuss these issues.

Design/methodology/approach

Endeavour has been made to explore the mechanism of gut colonization, selection criteria for probiotic cultures, mechanism of probiotic action, postulated health benefits and prerequisites of a probiotics food.

Findings

Probiotic organisms influence the physiological and pathological process of the host by modifying the intestinal microbiota, thereby affecting human health. Postulated health beneficial properties of probiotics suggest their application as functional foods.

Originality/value

Ingestion of cultured milk products containing probiotic cultures may provide health benefits in terms of colonization and normalization of intestinal flora and could be recommended for consumption as functional foods.

Abstract

Purpose

The authors sought to unpack the paradox between increasing demand for probiotics products against inconclusive scientific evidence about the effectiveness. This paper investigated public understanding of the composition and benefits of probiotic products, measured trust in news media and scientists as sources of information about probiotic products and informational and attitudinal predictors of consumer trust in the news media and scientists.

Design/methodology/approach

A cross-sectional survey was conducted amongst a representative sample of 2000 UK consumers. Participants responded to multiple-choice questions and psychometric scales capturing probiotics knowledge, consumption, information seeking behaviour, attitudes to and confidence in the news media and probiotics scientists. Descriptive statistics, one-way ANOVA and hierarchical regression modelling were performed.

Findings

Information exposure to probiotics content was highest from traditional media followed by online channels. Levels of confidence in probiotics scientists were higher than in the news media, even though these levels were highest amongst current consumers and lowest amongst non-consumers. Conflicting information, health consciousness and trust in nutrition stakeholders were identified as important predictors of trust in news media and scientists.

Originality/value

This study provides a large-scale nationally representative overview of public attitudes and sentiments related to probiotic products with a focus on attitudes towards the news media and the scientific establishment. The findings suggest a need for better consumer awareness about the state of science around probiotic products, interventions that could enable consumers to discern conflicting evidence or news reports, and critical skills that can render them more resilient to online misinformation.

Abstract

Purpose

The complex interaction between the gut flora and central nervous systems made probiotics one promising natural candidate for the management and treatment of depression. Hence, the purpose of this paper was to assess the knowledge, patterns of consumption and attitudes of patients with depression toward probiotics.

Design/methodology/approach

In this cross-sectional study, and through simple random sampling, 200 adults who were diagnosed with various depressive symptoms were selected. A link to a self-reported survey was sent to them with the aim of collecting sociodemographic data, assessing participants’ attitudes and knowledge toward probiotic consumption, and measuring their depression status via the Patient Health Questionnaire (PHQ-9).

Findings

A total of 164 participants (82%) provided usable responses. Approximately 55% of participants had moderate depression (PHQ-9). Participants (22.6%) tend to comply with their psychiatrists’ advice regarding probiotics more than other health specialists’ advice (p = 0.04). Only 59 (36%) had knowledge about probiotics and believed that probiotics should be consumed regularly and not only after an antibiotic course. However, many tended to follow marketing tricks and were willing to buy the most expensive and advertised probiotic products. Participants showed some differences in their attitude and knowledge toward probiotics according to symptoms severity; however, the differences were insignificant (p = 0.88).

Originality/value

To the best of the authors’ knowledge, this study is believed to be the first investigation assessing the probiotics’ knowledge, patterns of consumption and attitude of patients with various depression symptoms in Bahrain. The findings of this study may help improve the well-being of depressive patients by addressing the probiotic knowledge gap among them, expand the market of probiotics and enrich nutritional psychiatry literature.

Abstract

Purpose

This study aimed to identify the main and emerging structural patterns in the growth of the literature on probiotic research in food science, analyze current trends and determine gaps and present future projections.

Design/methodology/approach

A total of 1,301 scientific documents retrieved from Scopus database dated from 1993 to 2021 were analyzed by using bibliometric and scientometric tools.

Findings

The most influencer journals, leading countries and hotspots were identified by scientometric mapping. “Lactic acid bacteria”, “lactobacillus”, “lactobacillus plantarum”, “viability”, “functional foods” and “microencapsulation” were the top keywords that indicate main emerging areas. After a clear understanding of the current situation, future directions can be better projected. Therefore, investigating new probiotic microorganisms with advanced health promoting properties, adapting the new organisms to various food formulations, identifying the probiotic potential of unexplored traditional fermented foods and developing of nondairy probiotic foods can be the studies of the future.

Research limitations/implications

Probiotic concept has been revised during years and valuable knowledge has been accumulated over past decades. The findings demonstrate the development and trends of probiotic related food science researches. This is the first study to address the limitations of prior systematic literature reviews by applying network analysis and guide future works to fill the identified gaps.

Originality/value

The probiotic concept has been revised for years and valuable knowledge has been accumulated. Within the expanding literature, scientometric and bibliometric analysis will provide valuable contribution for identifying the main patterns, analyzing current trends, determining gaps and presenting future projection. This work presents detailed analysis to determine tendencies in probiotic research in food science.

Abstract

Purpose

Consumer inclination towards probiotic foods has been stimulated due to well-documented evidence of health benefits of probiotic-containing products and consumer demand for natural products. It is assumed that the viability and metabolic activities of probiotics are essential for extending health benefits and for successful marketing of probiotics as a functional food. The purpose of this paper is to demonstrate that even dead or inactivated probiotic cells could extend health benefits, indicating that probiotic viability is not always necessary for exhibiting health benefits.

Design/methodology/approach

Attempt has been made to review the literature on the status of probiotic foods available in the world market, their impact on the gut flora and the various factors affecting their viability. Both review and research papers related to efficacy of inactivated, killed or dead probiotic cells towards health benefits have been considered. Keywords used for data search included efficacy of viable or killed, inactivated probiotic cells.

Findings

The reviewed literature indicated that inactivated, killed or dead probiotic cells also possess functional properties but live cells are more efficacious. All live probiotic cultures are not equally efficacious, and accordingly, dead or inactivated cells did not demonstrate functional properties to extend health benefits to all diseases.

Originality/value

Capability of non-viable microorganisms to confer health benefits may attract food manufacturers owing to certain advantages over live probiotics such as longer shelf-life, handling and transportation and reduced requirements for refrigerated storage and inclusion of non-bacterial, biologically active metabolites present in fermented milks’ fraction as dried powders to food matrixes may result in the development of new functional foods.

Abstract

Purpose

During the ART era, persistent immune activation remains a significant challenge in people living with HIV (PLWH). Microbial translocation play an essential role in this setting. Probiotics have several immunological benefits which can reverse this process. The purpose of this paper is to investigate the safety and efficacy of probiotics on CD4 counts among Iranian PLWH.

Design/methodology/approach

In total, 50 PLWH with CD4 counts above 350 cells/mm3 did not receive ART participated in a randomized, double-blind trial and underwent 24 weeks of treatment with either LactoCare® or placebo twice daily. CD4 counts of the patients were measured at baseline, 12 weeks and 24 later in the two groups. Side effects were measured monthly using a specific checklist.

Findings

The mean CD4 count of the patients showed a significant difference between the two groups after six months. Through six months follow up, the mean CD4 count of the patients showed a significant reduction as compared to the baseline in the placebo group; however, it did not show a significant difference in the probiotic group. Repeated Measures Anova test showed a significant effect for time × treatment interaction on the CD4 count during the trial course. No significant difference between the two groups concerning adverse events was reported.

Originality/value

It seems the use of probiotics in PLWH with a CD4 count above 350 cells/mm3 who are not receiving antiretroviral drugs is safe and can reduce the devastating process of CD4+ T cells in these patients.

Abstract

Purpose

Probiotics confer protection against pathogens owing to their capability to compete with pathogens or their displacement by adhering to intestinal epithelial cells. Diverse health benefits extended by probiotics led to their application as functional foods. The aim of this paper is to explore probiotics as functional foods.

Design/methodology/approach

Endeavour has been made to explore prerequisites for a cultured milk product to be called as a probiotics food. Potentiality of probiotics for their exploitation as functional foods has also been delineated.

Findings

Probiotics demonstrate various prophylactic properties and their efficacy are influenced by strain of cultures employed. Probiotics confer diverse human health benefits such as normalization of intestinal flora, anticarcinogenesis, hypocholesterolemic effect, alleviation of lactose malabsorption and allergy. Beneficial properties of probiotics suggest their application as functional foods.

Originality/value

Ingestion of cultured milk products containing probiotic cultures may provide health benefits and could be recommended for consumption as functional foods.

Abstract

Purpose

The purpose of this study was to evaluate beet and orange mixed juices added with lyophilized Lactobacillus acidophilus probiotic culture.

Design/methodology/approach

Two formulations of probiotic beet and orange mixed juices (1:1 e 1:2 v/v) were prepared, stored at 4°C for 28 days and were evaluated for probiotic survival, physicochemical stability, antioxidant activity and sensory acceptance. The probiotic culture was added in a lyophilized form and was not propagated in culture media or juice.

Findings

Physicochemical characteristics (pH, titratable acidity, total soluble solids and color) and antioxidant activity showed no undesirable alterations during storage. The number of probiotics followed established minimum requirement for probiotic foods (109 CFU/200mL) during the 28 days of storage. The juices showed good sensory acceptance and purchase intention, especially regarding the color of the product.

Practical implications

The beet and orange mixed juices are suitable carriers for L. acidophilus with a shelf life of at least 28 days at 4°C.

Originality/value

Direct addition of the probiotic culture could result in high probiotic survival in mixed juices, dispensing the propagation step.

Abstract

Purpose

Increased evidence for the health benefits of probiotics for health restoration coupled with the consumer's inclination towards a safe, natural and cost-effective substitute for drugs have led application of probiotics as a pharmaceutical agent and are rapidly moving in clinical usage. In this context, this article attempts to highlight the potential of probiotics as a pharmaceutical agent.

Design/methodology/approach

Endeavor has been made to explore the significance of probiotics for the modulation of gut ecology and their action. Potentiality of probiotics for their exploitation as a pharmaceutical agent has also been justified. Limitations of probiotic therapy and the various considerations for probiotic therapy have also been delineated.

Findings

Probiotic organisms influence the physiological and pathological process of the host by modifying the intestinal microbiota, thereby affecting human health. Beneficial effects of probiotics as a pharmaceutical agent seem to be strain and dose dependent and more efficacious with their early introduction. Combination of various probiotics proved to be more efficacious than single strain for exhibiting prophylactic activities.

Research limitations/implications

Reviewed literature indicated that it is difficult to generalize for the beneficial effect of all probiotics for all types of diseases as efficacy of probiotics is strain-dependent and dose-dependent and its clinical application needs long-term investigations.

Practical implications

Clinical trials have displayed that probiotics may alleviate certain disorders or diseases in humans especially those related to gastro-intestinal tract.

Originality/value

Ingestion of fermented dairy products containing probiotic cultures may provide health benefits in certain clinical conditions such as antibiotic-associated diarrhoea, rotavirus-associated diarrhoea, inflammatory bowel disease, inflammatory bowel syndrome, allergenic diseases, cancer, Helicobacter pylori infection and lactose-intolerance. Application of probiotics as a pharmaceutical agent is recommended.

Abstract

Purpose

There is need for exhaustive studies to be undertaken to identify various probiotic strains and to understand the actual mechanism of action by which these probiotics exert their health benefits in order to exploit its fullest health benefits expressed by various kinds of the probiotic strains. The paper aims to discuss these issues.

Design/methodology/approach

The health effects of the probiotics can be accessed by in vivo as well as the in vitro studies of live microorganisms and their biological active compounds on various disease-causing organisms and their harmful metabolites.

Findings

The paper is a brief review of recent findings about the health benefits of probiotic strains of microorganisms. The health effects of fermented food items were known since the time immemorial, but the actual cause of this was a mystery. Recent discoveries led to the author's knowledge about the mechanism through which they exert these curative effects which is either by competitive inhibition of harmful microbes in gut or by production of biological active compounds against disease-causing organisms and their harmful metabolites.

Originality/value

Probiotics are commonly consumed as part of fermented foods which are produced with active live cultures, so various new types of these probiotic cultures can be introduced which can act as food as well as curative agents for treating and preventing various types of diseases at nominal costs.
