Abstract
Health claims may contribute to better informed and healthier food choices and to improved industrial competitiveness by marketing foods that support healthier lifestyles in line with consumer preferences. With the more stringent European Union regulation of nutrition and health claims, insights into consumers' health-related goal patterns and their reactions towards such claims are needed to influence the content of lawful claims. This study investigated how consumers' explicit and implicit health-related motive orientations (HRMOs) together with the type of calcium-claim (nutrition claim, health claim and reduction of disease risk claim) influence perceived credibility and purchasing intention of calcium-enriched fruit juice. Data were collected in April 2006 through a consumer survey with 341 Belgian adults. The findings indicate that stronger implicit HRMOs (i.e., indirect benefits of calcium for personal health) are associated with higher perceived credibility, which is not (yet) translated into a higher purchasing intention. Consumers' explicit HRMOs, which refer to direct benefits or physiological functions of calcium in the body-as legally permitted in current calcium-claims in the EU-do not associate with reactions to the claims. Independently of consumers' HRMOs, the claim type significantly affects the perceived credibility and purchasing intention of the product. Implications for nutrition policy makers and food industries are discussed.

Abstract
This research explored the effects of food choice motives, nutritional knowledge, and the use of food labels, on attitude toward food with health claims. Food with health claims was chosen as a relatively novel category of products designed to be beneficial for health. We identified eight motives served by food in general, and tested if they serve as motivations to positively evaluate functional food. Questionnaire was administered on nationally representative samples of 3085 respondents from six Western Balkan countries. We proposed two structural models relating an extensive list of eight and, alternatively, restricted list of three food-choice motives (health, mood and sensory appeal) to attitude toward functional food. We also expected the indirect association between the health motive and attitude, through nutritional knowledge and use of food labels. The results revealed highly positive, although undifferentiated attitude toward functional food, with no significant differences between the countries. The restricted model provided a better fit then the exhaustive model; the health motive was proven to have indirect influence on attitude through knowledge and label use. The implications of these findings for functional approach to attitudes, understanding the demand for functional food and overcoming barriers to dietary change are discussed.

Abstract
Health claims on food products are often used as a means to highlight scientifically proven health benefits associated with consuming those foods. But do consumers understand and trust health claims? This paper provides an overview of recent research on consumers and health claims including attitudes, understanding and purchasing behaviour. A majority of studies investigated selective product-claim combinations, with ambiguous findings apart from consumers' self-reported generic interest in health claims. There are clear indications that consumer responses differ substantially according to the nature of carrier product, the type of health claim, functional ingredient used or a combination of these components. Health claims tend to be perceived more positively when linked to a product with an overall positive health image, whereas some studies demonstrate higher perceived credibility of products with general health claims (e.g. omega-3 and brain development) compared to disease risk reduction claims (e.g. bioactive peptides to reduce risk of heart disease), others report the opposite. Inconsistent evidence also exists on the correlation between having a positive attitude towards products with health claims and purchase intentions. Familiarity with the functional ingredient and/or its claimed health effect seems to result in a more favourable evaluation. Better nutritional knowledge, however, does not automatically lead to a positive attitude towards products carrying health messages. Legislation in the European Union requires that the claim is understood by the average consumer. As most studies on consumers' understanding of health claims are based on subjective understanding, this remains an area for more investigation.

Abstract
Health claims on food products, which aim at informing the public about the health benefits of the product, represent one type of nutrition communication; the use of these is regulated by the European Union. This paper provides an overview of the research on health claims, including consumers’ perceptions of such claims and their intention to buy products that carry health-related claims. This is followed by a discussion on the results from some recent studies investigating public perceptions and willingness to use products with health claims. In these studies, claims are presented in the form of messages of different lengths, types, framing, with and without qualifying words and symbols. They also investigate how perceptions and intentions are affected by individual needs and product characteristics. Results show that adding health claims to products does increase their perceived healthiness. Claim structure was found to make a difference to perceptions, but its influence depended on the level of relevance, familiarity and individuals’ need for information. Further, the type of health benefit proposed and the base product used also affected perceptions of healthiness. The paper concludes that while healthiness perceptions relating to products with health claims may vary between men and women, old and young and between countries, the main factor influencing perceived healthiness and intention to buy a product with health claim is personal relevance.

Abstract
Background Consumer perception of the healthiness of beef is an important determinant of beef consumption. However, little is known about how consumers perceive the healthiness of beef. The aim of this study is to shed light on the associations between beef and health. Methods Eight focus group discussions were conducted in four European countries (France, UK, Germany, Spain), each consisting of seven to nine participants. A content analysis was performed on the transcripts of these discussions. Results Although beef was generally perceived as healthful, focus group participants expected positive as well as negative effects of beef consumption on their health. Labelled, branded, fresh and lean beef were perceived as signalling healthful beef, in contrast with further processed and packaged beef. Consumers felt that their individual choices could make a difference with respect to the healthiness of beef consumed. Focus group participants were not in favour of improving beef healthiness during processing, but rather focussed on appropriate consumption behaviour and preparation methods. Conclusions The individual responsibility for health implies that consumers should be able to make correct judgements about how healthful their food is. However, the results of this study indicate that an accurate assessment of beef healthiness is not always straightforward. The presented results on consumer perceptions of beef healthiness provide insights into consumer decision making processes, which are important for the innovation and product differentiation in the European beef sector, as well as for public health policy decisions related to meat consumption in general and beef consumption in particular.

Abstract
Dietary polyunsaturated fatty acid (PUFA) incorporation into bone may alter its metabolism through changes in the fatty acid composition of membrane phospholipids. Alteration of the membrane phospholipid fatty acid composition may influence bone cell signalling and, potentially, bone mineralization. The objective of this study was to use the fat-1 mouse, a transgenic model that synthesizes n-3 from n-6 PUFA, to determine if the fat-1 gene modulates the fatty acid composition of femoral and vertebral phospholipids, and if so, whether the fatty acid levels would correlate with bone mineral density (BMD) at both skeletal sites. Male and female wild-type and fat-1 mice were fed an AIN93-G diet, containing 10% safflower oil, from weaning to 12 weeks of age. The fatty acid composition of femoral and vertebral phospholipids was measured by gas liquid chromatography. At 12 weeks of age, phosphatidylcholine, phosphatidylethanolamine, and phosphatidylserine fractions in the vertebrae of fat-1 mice had a significantly lower n-6/n-3 ratio than wild-type mice (p < 0.05). In fat-1 femurs, these fractions, along with phosphatidylinositol, had a lower n-6/n-3 ratio than wild-type mice (p < 0.001). Docosahexaenoic acid (DHA) was positively correlated with BMD in all fractions in the vertebrae, and in phosphatidylinositol and phosphatidylserine in the femur (p < 0.05). Overall, the fat-1 gene resulted in changes in the fatty acid composition of both femoral and vertebral phospholipids. Significant correlations between DHA and BMD may indicate a positive effect on bone mineralization.

Abstract
This study evaluates the effect of a health claim and personal characteristics on the acceptance of two unfamiliar açaí fruit juices that have a low (40% açaí) versus a high (4% açaí) a priori overall liking. Hedonic and sensory measures as well as health- and nutrition-related attribute perceptions and purchase intention were rated before and after health information was presented. Differences in information effects due to interactions with juice type, consumer background attitudes and socio-demographics were investigated. Providing health information yielded a positive, though rather small increase, in overall liking, perceived healthiness and perceived nutritional value of both juices, as well as in their purchase intention. Sensory experiences remained predominant in the acceptance of the fruit juices, although the health claim had a stronger effect on the perceived healthiness and nutritional value of the least-liked juice. Background attitudes and socio-demographic characteristics influenced consumers' acceptance of both unfamiliar fruit juices. Health-oriented consumers were more likely to compromise on taste for an eventual health benefit, though they still preferred the best tasting juice. Consumers with a high food neophobia reported a lower liking for both unfamiliar fruit juices. Older respondents and women were more likely to accept fruit juices that claim a particular health benefit.
