Abstract

Purpose

Dietary supplements have been subject to considerable criticism because of their lack of regulation and questionable claims; yet, research indicates that consumers who are more health conscious are more likely to use supplements because the products are associated with preventive health behaviors. This research aims to examine whether consumers’ familiarity with supplement advertising or their level of health consciousness significantly affects their attitudes toward three different types of dietary supplements. It also assesses whether advertising familiarity and health consciousness are related to perceptions of supplement price.

Design/methodology/approach

This paper used a point-of-purchase approach and collected data at a nationwide supplement retail store in a major metropolitan area in the southeast, resulting in a final sample of 136 consumers. In addition to the survey items, data were collected on a number of demographic factors, including gender, age, marital status, race and education.

Findings

Results suggest that health consciousness is significantly related to attitudes toward different supplement types and perceptions of supplement price, but familiarity with supplement advertising is not related.

Practical implications

The results suggest that health consciousness is a significant predictor of attitudes toward different nutritional supplements and the perceived price of supplements, but familiarity with advertising is not a predictor. Implications for marketers and public policy are provided.

Originality/value

While this research informs public policy, it is especially useful for marketers and advertisers of dietary supplements.

Abstract

Purpose

This study aims to examine and validate the role of electronic word of mouth (eWOM), a mediating factor between the marketing mix elements (product, price, place and promotion) and women's purchasing intention of children's dietary supplements in the Jordanian environment culture context.

Design/methodology/approach

The data of the research was collected through online and offline questionnaires using a connivance sample of 370 women who have children and live in Amman, the largest city in Jordan.

Findings

The findings showed a partial effect of the eWOM as mediating factor on the relationship between marketing mix elements and women's purchasing intention of children's dietary supplements. The findings also revealed significant positive effects of price and place as marketing mix elements on women's purchasing intention of children's dietary supplements, while the product and promotion elements were found insignificant.

Originality/value

This paper contributed to consumer buying behaviour theories by filling a gap in the literature regarding the role of eWOM as a mediating factor on the relationship between marketing mix elements and women's purchasing intention of children's dietary supplements in a developing country like Jordan for the first time.

Abstract

Purpose

Obesity is a chronic disease that is conjoined with increased mortality. Parallel to rising obesity rates, herbal dietary interventions to lose weight are also increasing. The purpose of this study is to assess and evaluate the use of herbal dietary interventions for weight loss among regularly exercising women.

Design/methodology/approach

A total of 545 regularly exercising women (aged 19–64 years) were recruited from several local sports centers. A questionnaire form to evaluate demographic characteristics, nutritional habits and herbal dietary intervention habits was administered by a trained dietitian. Anthropometric measurements including weight, height, fat mass, total body water and fat free mass were measured using a bioelectrical impedance analysis device.

Findings

A total of 244 participants (44.8%) used herbal dietary interventions for weight loss within the last year. The most commonly used herbal dietary interventions were green tea (59.4%), lemon juice (27%), herbal tea mix (20.9%) and cinnamon powder (17.6%), respectively. Of the 244 women who used herbal dietary interventions for weight loss, 42.2% claimed that by using these products they experienced weight loss. Herbal dietary interventions were significantly higher among women with obesity (61.9%) than women with a healthy weight (37.5%). The use of herbal supplements increased among women who consider themselves as being overweight (p < 0.001). Furthermore, herbal dietary interventions decreased with more frequent attempts for a weight-loss diet (p < 0.001).

Originality/value

To the best of the authors’ knowledge, this study represents a first attempt at assessing the use of herbal dietary supplements for weight loss among regularly exercising Turkish women. With the increase of body mass index and body perception being as overweight, herbal dietary interventions were also increased. In particular, women with obesity (61.9%) used more herbal dietary interventions than women with healthy weight (37.5%). Moreover, women with an overweight body perception used more herbal supplements than those who thought they had a healthy body weight.

Abstract

Purpose

The purpose of this study is to investigate food supplement intake among gym-goers.

Design/methodology/approach

A cross-sectional study, using a validated questionnaire, was conducted. All participants were gym-goers who voluntarily enrolled from eight selected gyms in Perugia. A multivariate regression analysis was performed.

Findings

In our sample, 44.9per cent (n = 57) of participants consumed dietary supplements, at least once a week, with no association with sex (p = 0.5) and educational level (p = 0.4). Supplements intake was statistically significant and associated with very low intake of mineral water (p = 0.01), diet specific for fitness programmes (p < 0.01), information about nutrition from personal trainers (p < 0.01), frequency of physical activity (p = 0.01), society’s attention to nutrition (p = 0.04) and marginally with frequency of weigh control (p = 0.05).

Originality/value

Food supplements intake seems to be extensively used among gym-goers, and it seems related to information about nutrition from personal trainers. However, specialized personnel, such as dietitian or nutritionist, should supervise supplements intake.

Abstract

Purpose

As no prior attempt has been made to investigate the role of weight-related teasing (WRT) as a source of motivation towards impulsive purchase intention of weight loss dietary supplements, this study aims to investigate the factors of devalued self-esteem, weight concerns, dysfunctional eating cognitions, depressive symptoms, attitude, subjective norms and perceived behavioural control from a generation Z perspective.

Design/methodology/approach

A qualitative study and a cross-sectional survey design has been used along with passive research deception approach where data has been obtained from 377 obese and overweight participants from eight major Indian cities using intercept approach. Besides, verifying the questionnaire using principal component analysis and internal consistency, the provided hypotheses are evaluated by structural equation modelling and its related tests. Inductive content analysis method has also been applied for the qualitative analysis.

Findings

The findings indicate that the hypothesized factors have a considerable influence on one another, implying acceptance of all 12 proposed hypotheses. Additionally, this study suggests that generation Z individuals are swayed more by price and impulsiveness than by product quality. Even though people prefer purchasing such supplements primarily for quicker results, people fear potential health hazards in the future.

Originality/value

This study links WRT from a psychosocial perspective by focusing on youth consumer behaviour. With the limited number of works on concerned variables, this study addresses vital issues concerning generation Z individuals’ health attitude.

Abstract

Purpose

Coronavirus disease-2019 (COVID-19) is becoming a crucial health problem worldwide. Continued and high-speed mutations of this virus result in the appearance of new manifestations, making the control of this disease difficult. It has been shown that well-nourished patients have strong immune systems who mostly have short-term hospitalization compared to others. The purpose of this study is to review the major nutrients involved in the immune system reinforcement and to explain nutritional aspects during the recovery of COVID-19.

Design/methodology/approach

In this review paper, the mechanistic role of nutrients in boosting the immune system and the nutritional aspects during the recovery of COVID-19 patients were discussed. Papers indexed in scientific databases were searched using antioxidants, COVID-19, inflammation, immune system, macronutrient, micronutrient and probiotic as keywords from 2000 to 2022.

Findings

Because of the adverse effects of drugs like thrombosis, pulmonary embolism and hypercholesterolemia, a balanced diet with enough concentrations of energy and macronutrients could increase the patient's durability. The inflammatory cytokines in a vicious cycle delay patients’ rehabilitation. The main mechanistic roles of micronutrients are attributed to the downregulation of virus replication and are involved in energy homeostasis. Dysbiosis is defined as another disturbance among COVID-19 patients, and supplementation with beneficial strains of probiotics helps to exert anti-inflammatory effects in this regard. Being on a well-planned diet with anti-inflammatory properties could reverse cytokine storms as the major feature of COVID-19. Future studies are needed to determine the safe and effective dose of dietary factors to control the COVID-19 patients.

Originality/value

Being on a well-planned diet with anti-inflammatory properties could reverse cytokine storms as the major feature of COVID-19. Future studies are needed to determine the safe and effective dose of dietary factors to control the COVID-19 patients.

The purpose of this study is to assess the protein (biological) quality of pecan and pine nuts supplemented diets in male Wistar albino rats.

Abstract

Purpose

The purpose of this study is to assess the protein (biological) quality of pecan and pine nuts supplemented diets in male Wistar albino rats.

Design/methodology/approach

A randomized and controlled study (45 d) was conducted in male Wistar albino rats (n = 60) comprising six groups, namely, control (Cc), control with 1% cholesterol (CC1), Pecan group (Pe), Pecan group supplemented with 1% cholesterol (Pi1), Pine group supplemented with 1% cholesterol (Pi1). Protein quality of supplemented diet/s was assessed in terms of various biological indices.

Findings

Pe and Pi groups exhibited normal growth when compared with Cc. Despite showing higher feed and protein intake, Pe and Pi groups exhibited significantly (P = 0.023) lower weight gain than Cc. There was no significant difference between the protein efficiency ratio (3.8 ± 0.2 and 3.7 ± 0.2), apparent protein digestibility (81.5 ± 2.2 and 80.5 ± 2%), true protein digestibility (90.6 ± 1.1 and 88.5 ± 3.5%) and biological value (BV) (75.6 ± 0.9 and 72.6 ± 0.9%) of Pe and Pi groups, respectively. Pe group presented considerably higher net protein utilization (68.5 ± 1.4 vs 64.4 ± 0.8%) and protein retention efficiency (34.8 ± 1.1 vs 31.2 ± 1.3%) than Pi group. Overall, pecan-based diet displayed superior biological quality over pine nut. Antinutrients present in the nuts did not show any major negative effect on the growth, digestibility and bioavailability of the nutrients in rats. BV ranging from 72.6% to 75.6% suggested a satisfactory quality of experimental nut-based diets.

Research limitations/implications

Further investigation of pecan and pine nuts consumption to examine the potential benefits and associated mechanisms of action is warranted which would aid in a better understanding and to establish nutritional recommendations.

Originality/value

Overall, the exploitation of pecan and pine nut flours for the development of value-added food products is favorable from a nutritional point of view.

Abstract

Purpose

The purpose of this paper is to identify the demographic and psychographic characteristics of older green tea consumers in the USA. By understanding this segment’s background, perceptions, and behaviors, health and marketing professionals can tailor messages to reach clients and consumers.

Design/methodology/approach

An online survey was completed in January 2014 with 1,335 older adult consumers (=55 years old). Data were analyzed using descriptive statistics and binomial logistic regression.

Findings

More than half (n=682, 51.2 percent) of respondents drank green tea. Most green tea consumers in this sample are college-educated and employed female home owners. The odds for green tea consumption are greater if a respondent is in good health, was informed about diet and health, or made a health-related dietary change in the past year. There are greater odds of consumption if the respondent is familiar with the relationship between drinking green tea and the reduced risk of cancer however, the importance of health statements on product labels are not predictive of consumption.

Research limitations/implications

This study was conducted in the USA and with older adults. Future research should explore characteristics of younger consumers, i.e. 18-54 years old.

Practical implications

Health educators, regulators, and marketing professionals may use this profile to tailor messages that speak to consumers and client’s values and motivations.

Originality/value

To the authors’ knowledge, this is the first profile of older adult green tea consumers in the USA.

Abstract

Purpose

The purpose of this paper is to analyse differences in sociodemographic and sporting characteristics, health-behaviours, and food intake of athletes using and not using nutritional supplements (NS).

Design/methodology/approach

High-performance Portuguese athletes from 13 sports completed a NS usage questionnaire, assessing information on sociodemographic (sex, age, height, weight, athlete’s, and parental education level), health-related (smoking, daily time of sleeping, walking, and sitting), and sporting (type, number of international performances, weekly hours of training and weekly hours of gym) characteristics; and a semi-quantitative food-frequency questionnaire (86 items), regarding the previous 12 months.

Findings

From the 241 athletes (66 per cent males, 13-37 years), 64 per cent reported NS use. Supplement usage was associated with age 18 years (odds ratio (OR) 2.57, 95 per cent; confidence interval (CI) 1.17-5.65), performing individual sports (OR 5.45, 95 per cent; CI 2.49-11.93) and > 2 h gym/week (OR 2.42, 95 per cent; CI 1.15-5.11), a higher consumption of meat (OR 2.83, 95 per cent; CI 1.36-5.90), eggs (OR 2.53, 95 per cent; CI 1.07-5.96), and yogurt (OR 2.24, 95 per cent; CI 1.08-4.62), and a lower intake of processed meat (OR 0.32, 95 per cent; CI 0.15-0.72), vegetable oils (OR 0.35, 95 per cent; CI 0.17-0.74), margarine (OR 0.37, 95 per cent; CI 0.18-0.76), chips (OR 0.22, 95 per cent; CI 0.10-0.48), and fast food (OR 0.42, 95 per cent; CI 0.19-0.91).

Originality/value

Athletes using NS had different characteristics from non-users, and seemed to have healthier and more sports-oriented food choices. Our findings may help sport and health professionals to identify an alleged or future NS user, enabling the development of a timely and self-directed supplement scheme.
