PurposeTo survey consumers living in Paris, France, to determine the extent to which they use nutrition labels, and to determine the percentage of French consumers who use nutrition labels, how often they use nutrition labels, and how they would like to see current nutrition labels improved. The researchers also wanted to determine the reasons why consumers do not use nutrition labels, and to try and assess users' and non‐users' perceptions about mandatory nutrition labelling.Design/methodology/approachFrench consumers (n = 355) were surveyed in supermarkets in Paris and its suburbs, using a 21‐item questionnaire in May 2004. Interviewers used questionnaires to assess the frequency of respondents' nutrition label use, to investigate the specific nutrient information most commonly consulted on nutrition labels, the types of products on which consumers most often tend to consult nutrition labels, and to collect demographic information.FindingsOnly 45.1 per cent of the sample reported reading nutrition labels, with the majority of consumers reading labels only occasionally. Non‐label readers cited lack of interest as the primary reason why they do not read labels, but 95 per cent of the sample, when asked about mandatory nutrition labeling, felt that nutrition labeling should be required of food manufacturers. Research limitations/implications The sample size was small, participation was voluntary and was limited to the city of Paris and its suburbs, and therefore cannot be generalized to the French population.Originality/valueThis is the first study to collect data in a point‐of‐purchase setting in order to examine whether or not French consumers use nutrition labels.
The present study was conducted to determine differences in antioxidant levels of fresh, frozen, and freeze-dried strawberries, and strawberry jam. Hydrophilic antioxidant activity (HAA) and lipophilic antioxidant activity (LAA) were measured using the ABTS/H₂O₂/HRP decoloration method. HAA and LAA were then summed to calculate the total antioxidant activity (TAA). Mean differences in HAA and LAA were analyzed using one-way analysis of variance and Dunnett's T3 pairwise comparisons. The mean TAA for freeze-dried strawberries based on an 'as consumed' weight (95% confidence interval [CI]: 29.58, 30.58) was significantly higher than for fresh (95% CI: 3.18, 3.66), frozen (95% CI: 2.58, 2.79), and jam (95% CI: 1.10, 1.22). The mean TAA based on dry weight for fresh strawberries (95% CI: 40.48, 46.67) was significantly higher than for freeze-dried (95% CI: 29.58, 30.58), frozen (95% CI: 24.62, 26.59), and jam (95% CI: 1.48, 1.64). Results agree with previous studies reporting that strawberries are a valuable source of antioxidants for consumers.
Fish and seafood, kilocalorie, and oil-crop availability appear to be related to CVD mortality, but further investigation is needed. Associations between diet and CVD mortality create the opportunity to target specific countries for nutrition education and CVD prevention programs.
The present study examined the effects of domestic cooking methods on the hydrophilic antioxidant activity (HAA) of wild blueberries. Baked, microwaved, simmered, and pan-fried frozen wild blueberries, and a thawed uncooked control, were analyzed for HAA using an ABTS/H(2)O(2)/HRP decoloration method. All cooking treatments were derived from recipes using wild blueberries, and were performed in triplicate. A randomized block design was used to determine whether there were statistical differences in antioxidant content after cooking and between each of the trials. There were no statistically significant decreases after cooking the thawed berries. On both a fresh weight and a dry weight basis, pan-fried blueberries had significantly higher HAA than baked, simmered, and control blueberries (P<0.05). Antioxidants in wild blueberries appear to be heat stable since cooked berries retained significant HAA. Cooked wild blueberries can be recommended as a good source of dietary antioxidants.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
