A Hypothetical Tavern Menu for the Evaluation of Calorie Selection through Menu Labelling.

The purpose of the present study is to evaluate calories selection according to the type of menu labelling applied on a hypothetical Greek tavern menu. Three questionnaires were designed and each one included a hypothetical menu of Greek tavern food. Menu A did not include any nutritional information, Menu B included calorie posting and Menu C had the "NB" mark next to dishes that were Nutritionally Balanced choices. A total of 437 participants were recruited in the study. The mean calories selection was significantly lower on Menu B (1874 Kcal) and C (1787.7 Kcal) compared to Menu A (2157.3 Kcal). The overweight and obese participants ordered significantly fewer calories on Menu B (-504 Kcal and -404 Kcal) and C (-451.3 Kcal and -393 Kcal) than on the Menu A. Menu labelling should be assessed in real-life settings in Greece. It could be a policy for the prevention and control of obesity in European countries.

Do ready-to-eat meals of Greek supermarkets need reformulation?

The purpose of this study is to evaluate the nutritional value of ready-to-eat meals available in Greek retail outlets. A total of 228 meals were identified, their nutritional value was registered according to their labels and a comparison was performed against specific nutritional criteria for the macronutrients, per serving. The 183 products were main dishes and 45 were salads and appetisers. The 28.9% of salads and appetisers were within the calorie cut-off point (250Kcal), the 82.2% of them contained more salt than the limit (0.75 g), whereas 22.2% were within the limit of fat (9 g). 72.1% of the main dishes had fewer calories than the cut-off point (600 Kcal), 12.6% of them had less salt than the limit (1.8 g) and 48.1% of them were within the limit for fats (21 g). Companies should reformulate their offered ready-to-eat meals in terms of their fat and salt content in order to provide the consumers with balanced meals.

Recovery of antioxidant phenolics from white vinification solid by-products employing water/ethanol mixtures.

Solid wastes from white vinification, including grape peels, seeds and stems, were used as raw material for the recovery of antioxidant polyphenols. Extractions were performed using non-toxic media composed of water/ethanol mixtures and hydrochloric, acetic or tartaric acid. Recovery efficiency was assessed by monitoring the antioxidant potency of extracts and several indices related to their polyphenolic composition, including total polyphenol, total flavonoid, total flavanol and condensed tannin (proanthocyanidin) content. Among the by-products tested, seeds were shown to contain exceptional amounts of total polyphenols (13.76 g per 100g dry weight), followed by stems (7.47 g per 100g dry weight) and peels (0.97 g per 100g dry weight). Extracts with the highest antioxidant activity from all by-products were obtained with 57% ethanol. Acidification of this medium with 0.1% HCl improved polyphenol recovery and antiradical activity for stem extracts, but it was unfavourable for seed extraction.

Constituents of red wine other than alcohol improve endothelial function in patients with coronary artery disease.

BACKGROUND: Several studies suggest that red wine is beneficial in coronary artery disease (CAD). Although the long-term effect of moderate red wine consumption on endothelial function is currently under investigation, there is little knowledge about its effect on postprandial endothelial function and haemostatic factors. The aim of the present study was to investigate the postprandial effects of alcohol content and the antioxidants of red wine on endothelial function and fibrinogen levels in CAD patients. METHODS: Fifteen males with angiographically documented CAD were recruited for the study. All volunteers ingested 250 ml of either red wine or de-alcoholized red wine on two different days. Blood samples (for analysis of fibrinogen and blood lipids) were collected and flow-mediated dilatation (FMD) was determined before and 30, 60 and 90 min following consumption of each beverage RESULTS: FMD was higher following the consumption of de-alcoholized red wine [type of wine effect, P=0.05 repeated measures analysis of variance (ANOVA)]. Furthermore, the pattern of the response was different between the two beverages, as FMD increased following the ingestion of de-alcoholized red wine, but it decreased after consumption of regular red wine (type of wine by time interaction effect, P=0.006 repeated measures ANOVA). Fibrinogen concentrations were unaltered CONCLUSIONS: Acute ingestion of red wine without alcohol led to higher FMD than ingestion of regular red wine in CAD patients. The acute effect of red wine on endothelial function may be different than its long-term effect and it could be attributed to its constituents other than alcohol.
