Healthy Food,Healthy Teeth: A Formative Study to Assess Knowledge of Foods for Oral Health in Children and Adults

Eating patterns characterised by low intakes of processed carbohydrates and higher intakes of fat- and Vitamin D-rich foods are associated with protection against dental caries. The aim of this formative study was to evaluate the extent to which the knowledge of children and adults of foods for oral health reflects dietary guideline advice, and the evidence base for foods associated with increased and decreased caries burdens. Using a novel card-sorting task, the participants categorised foods according to their knowledge of each food for oral health. There were no differences between children and adults in the categorisation of fresh, minimally processed foods. Fish, chicken, and red meat were categorised as healthy by significantly fewer children than adults. High-sugar foods were correctly characterised as unhealthy by nearly all participants. More children categorised breakfast cereals as healthy than adults. There were no statistically significant differences between children and adults for the categorisation of brown or wholegrain breads categorised as healthy. The alignment of the participants’ beliefs with dietary guideline recommendations suggests education through health promotion initiatives is successful in achieving knowledge acquisition in children and adults. However, recommendations to increase the intake of refined carbohydrates inadvertently advocate foods associated with increased caries burdens.     

保健食品看坚果

关注健康、珍爱生命.把健康与生命掌握在自己手中。已成为现代人们的一种共识,一种追求。传统的习俗"一日三餐",被认为常规正确摄取营养的饮食方式。现代医学表明,在一日三餐间增加些休闲食品(坚果).才是全面摄取营养的好方法。 休闲食品俗称零食.传统的休闲食品.以油炸类、果品类、糕点类、糖果类等为主.由于高糖、高脂肪、高热量的摄入(水果、果汁除外)引发现代文明病屡见不鲜。而休闲食品--坚果,伴随人类数千年的天然食品,是     

保健食品中仙人掌抗氧化作用的研究

仙人掌属多肉植物，无毒性，有资料报道仙人掌中含有大量植物黄酮类化合物、各种维生素和氨基酸等成份。但其作为保健食品的抗氧化作用尚无相关报道。本次研究的主要目的是对仙人掌在保健食品中抗氧化作用的研究。以期了解仙人掌是否具有抗氧化作用及有效成分和作用剂量的效应关系。     

Neighborhood Impact on Healthy Food Availability and Pricing in Food Stores

Availability and price of healthy foods in food stores has the potential to influence purchasing patterns, dietary intake, and weight status of individuals. This study examined whether demographic factors of the store neighborhood or store size have an impact on the availability and price of healthy foods in sample of grocery stores and supermarkets. The Nutrition Environment Measures Study-Store (NEMS-S) instrument, a standardized observational survey, was utilized to evaluate food stores (N = 42) in a multi-site (Vermont and Arkansas) study in 2008. Census data associated with store census tract (median household income and proportion African-American) were used to characterize store neighborhood and number of cash registers was used to quantify store size. Median household income was significantly associated with the NEMS healthy food availability score (r = 0.36, P < 0.05); neither racial composition (r = −0.23, P = 0.14) nor store size (r = 0.27, P = 0.09) were significantly related to the Availability score. Larger store size (r = 0.40, P < 0.01) was significantly associated with the NEMS-S Price scores, indicating more favorable prices for healthier items; neither racial composition nor median household income were significantly related to the Price score (P’s > 0.05). Even among supermarkets, healthier foods are less available in certain neighborhoods, although, when available, the quality of healthier options did not differ, suggesting that targeting availability may offer promise for policy initiatives. Furthermore, increasing access to larger stores that can offer lower prices for healthier foods may provide another avenue for enhancing food environments to lower disease risk.     

Healthy Food Identification: Food Cues and Claims Affect Speeded and Thoughtful Evaluations of Food

This study investigated the impact of food claims, food cues, and objective health characteristics on health categorization speed and accuracy, believability of claims and perceptions of health, and taste for food items. One hundred twenty-four young adults were exposed to counterbalanced food item images, which varied by directness of visual food cues, type of food claims (health-related vs. taste-related), and objective healthfulness in a fully crossed design across three different food items. Participants categorized the foods as healthy or unhealthy in a speeded task and evaluated the perception of claim believability and perceptions of health and taste after exposure to images of the food items. Direct visual cues, especially when used with health claims, improved health and taste perception ratings and aided believability of health claims even for objectively unhealthy food products.     

Brand Name Logo Recognition of Fast Food and Healthy Food among Children

The fast food industry has been increasingly criticized for creating brand loyalty in young consumers. Food marketers are well versed in reaching children and youth given the importance of brand loyalty on future food purchasing behavior. In addition, food marketers are increasingly targeting the Hispanic population given their growing spending power. The fast food industry is among the leaders in reaching youth and ethnic minorities through their marketing efforts. The primary objective of this study was to determine if young children recognized fast food restaurant logos at a higher rate than other food brands. Methods Children (n = 155; 53% male; 87% Hispanic) ages 4-8 years were recruited from elementary schools and asked to match 10 logo cards to products depicted on a game board. Parents completed a survey assessing demographic and psychosocial characteristics associated with a healthy lifestyle in the home. Results Older children and children who were overweight were significantly more likely to recognize fast food restaurant logos than other food logos. Moreover, parents' psychosocial and socio-demographic characteristics were associated with the type of food logo recognized by the children. Conclusions Children's high recognition of fast food restaurant logos may reflect greater exposure to fast food advertisements. Families' socio-demographic characteristics play a role in children's recognition of food logos.
