Osteoarthritis is a degenerative change in the joint that causes damage to the articular cartilage, resulting in overexpression of inflammatory cytokine in the damaged chondrocytes, which leads to damage to the articular cartilage and is completely treated with antibiotics. We recovered the damage to the articular cartilage caused by osteoarthritis and investigated the effect of a low-molecular-weight collagen-based functional material without side effects. In this study, we investigated the ameliorative effects of YB in a monosodium idoacetate(MIA)-induced osteoarthritis rats. The experimental groups were divided with 5groups (n = 12) of SD rat: normal control(NC), MIA, MIA+L. plantarum (3×1011 CFU/ml), MIA+collagen and MIA+YB-21. Histological examinations indicated that YB-21 cartilage structure change, cartilage cell damage, and the loss of proteoglycan induced by MIA. Moreover, YB-21 reduced serum level expressions of, tumor necrosis factor-α(TNF-α), Interleukin6(IL-6), Interleukin1β(IL-1 β), Matrix metalloproteinase-9(MMP-9), Tissue inhibitor of metalloproteinases-1(TIMP-1). These results suggest that YB has a positive effect on osteoarthritis by restoring joint cartilage and anti-inflammatory effects due to the reaction of osteoarthritis in the MIA-induced rat.

Inflammatory bowel disease (IBD) is a chronic inflammatory disorder of the colon and rectum with intervals of acute exacerbation. Its etiology remains unknown, although recent studies suggest that pro-inflammatory cytokines initiate the inflammatory responses. In this study, we investigated the ameliorative effects of YB-21 (new product containining Lactobacillus plantarum, Barley Bran and Nymphaeaceae) in a dextran sulfate sodium (DSS)-induced colitis in mice. The experimental groups were divided into 6 groups (n = 10) of ICR mice: normal control(NC), DSS-treated(PC, positive control), DSS+latic-L-treated (3×107CFU/ml), DSS+latic-M-treated (3×109CFU/ml), DSS+latic-H-treated (3×1011CFU/ml), and DSS+YB-21-treated. Histological examinations indicated that YB-21 suppressed edema, mucosal damage, and the loss of crypts induced by DSS. Moreover, YB-21 reduced serum level expressions of, tumor necrosis factor-α (TNF-α). These results suggest that YB-21 has an anti-colitic effect by the suppression of intestinal inflammatory responses in DSS-induced colitis in mice.

Food has become a significant lifestyle and life quality generator, and consumers are increasingly developing food regimes with expectations of healthier, happier selves. The global food industry has turned to delivering towards these expectations, and functional foods form a significant multimillion dollar growth category. Fortified with added health-giving compounds, these foods are promoted as the modern, convenient way of obtaining health benefits from food intake itself, rather than from the use of vitamin supplements (Grunert, 2013). However, there are indications that their appeal and usage varies considerably across nations. Somewhat surprisingly, few studies have considered functional food consumption through a culturally mediated lens, as consumption entities used to convey and transfer meaning. This research explores personal meaning making for one such proposed functional food concept. Foods which are fortified to enable greater control over hunger control are currently under development as potentially assisting those seeking weight loss. The data consisted of 14 in-depth phenomenological interviews with New Zealand women who were attempting weight loss. Participants discussed their lived food and weight loss experiences and then freely responded to the weight loss foods concept. The findings reveal the omnipresent nature of weight loss practices in daily lives, with the perception of success, or failure, sometimes underpinning one’s sense of self. As found by Willis & Knobloch-Westerwick (2014), motivations for weight loss were dominated by appearance and body image concerns, driven by the continuation of persistent societal expectations privileging thinness. Extending this, the present research found a conflation of motivations where slimness was seen to equate to healthiness. A line of progression in the types of practices was revealed where many ‘fad diets’ were attempted with typically unsuccessful long term results. Although, healthism was internalised as an overriding way of thinking about food and weight loss practices, paradoxically, this often co-existed with the desire for foods of indulgence, especially for those identifying as emotional eaters. Vastly different dispositions were revealed towards the proposed innovation of the fortified weight loss foods. These were interpreted as being aligned with perceptions of identity (Tajfel & Turner, 1986). Whilst the overall fortification of foods was viewed negatively, risks and doubts were mitigated in some cases in the interest of trying the proposed foods. The research findings resonated with societal contradictions observed for food consumption (Warde 1997), and paradoxes specifically theorised for technology (Mick & Fournier, 1998). Although, technology has been theorised to be a positive enabler in consumers’ lives, offering feelings of freedom, competence, and control, it can also be regarded as an intrusion, leading to feelings of enslavement and incompetence (Mick & Fournier, 1998). Whilst there was the promise of enhanced health and wellness from a bio-technological innovation, this contradicted central beliefs about what it means to be healthy, where food for many consumers represents values of naturalness, purity, nostalgia, and simplicity (Barsky, 1988; Biltekoff, 2010). Implications of the research for functional foods marketers are outlined, advocating the need for continuing understanding of the paradoxical aspects of consumption in contemporary health contexts.

Functional foods are of great significance since our society is accelerating into aging. An aging society has many physiological metabolic diseases such as hypertension, diabetes, heart disease, cancer, dementia and geriatric diseases. Fundamental treatments for the elderly are almost impossible and the social burden is heavy. If these diseases can be prevented or alleviated by improving dietary habits using functional foods, the significance would be very large. Pomegranate has been found to have 124 different kinds of phytochemicals. Polyphenols have a wide range of protective effects including various physiological metabolic diseases and cancers. It is necessary to develop functional foods such as preservatives and food extenders which can contribute to food safety, required in the food industry, by using such bioactive substances. Pomegranates have been reported to decrease the impact of many serious illnesses. There is a considerable amount of bioactive substances in the peel of a pomegranate, which has potent anticancer, antioxidant, antimicrobial and anti-apoptotic properties. Unfortunately, the peel is typically discarded after processing. Despite knowledge regarding the bioactive substances in the pomegranate peel and peel extracts, including their functionality and diversity, the knowledge is not well known by consumers in general. The aim of this study was to review up to date research trends for processing and developing new functional foods by utilizing nutritional functional substances, favourite food materials, and materials for processing food contained in pomegranate peels and pomegranate peel extracts. This study will summarize the data found in pomegranate peel and pomegranate peel extract literature mainly recently published in Science Direct. There are polyphenolic compounds (ellagitannins, punicalagin, proanthocyanidin, flavonoids, polysaccharides, etc.) in the fruit peel, making up about 50% of the pomegranate’s weight. The polyphenol content of a pomegranate fruit peel is 149.91 mg/g, which is about 100 times higher than the juice. Paying attention to the fact that the ellagitannin content (14.22 mg/g) in the fruit peel is also twice as high as that of the fruit juice and seeds, that confirms the possibility of utilizing the peel as a food ingredient capable of developing new, functional bioactive foods.

The purpose of this study was to find efficient and customized tools for delivering the benefit of health functional foods (HFFs). Delivery tools which could influence the impact of advertising were images, explanations of ingredients, diagrams of health benefit, patents, and comments from authority. Six advertisements were developed using these tools: “A”: relevant image + explanation of ingredients + scientific diagram of efficacy; “B”: relevant image + explanation of ingredients; “C”: relevant image; “D”: irrelevant image; “E”: irrelevant image + explanation of ingredient + patent; “F”: irrelevant image + explanation of ingredient + comments from authority. To analyze the consumer perceptions on HFFs and advertisement effects, 300 respondents were requested to answer a questionnaire comprising of the following questions: 5 questions of attitudes (necessity of HFFs, trust in HFFs, gathering information, watching advertisements and trust in advertisement claims) and 6 questions on the 6 developed advertisements (attention, understanding, sufficiency of information, sympathy, trust, and purchase). Scoring was done as per the 5 Likert scale. There was a higher proportion of females and the elderly, as compared to males and youngsters. The overall consumer attitudes were positive. Explanation of ingredients, scientific diagram of health benefit, patents and expert comments were helpful factors in increasing the advertisement evaluation by consumer, but the images were not. Advertisement evaluation of consumer did not differ with gender and age. However, differences were observed between some of the consumer attitudes (necessity of HFFs, trust in HFFs, gathering information and trust in advertisements claim) and advertisement evaluations (attention, understanding, sympathy and purchase). Our results indicate that for consumers utilizing the HFFs, advertisements with concrete tools such as diagrams, patent, and expert comments are more helpful. However, for consumers who do not have interest in HFFs, the scientific information was irrelevant. We believe that to maximize the effect of health information in advertisements, consumers should be segmented, and customized tools for each segment needs to be developed.
