Abstract Objectives To assess the overall nutritional quality of meals chosen by undergraduate students during weekday lunches at campus all-you-care-to-eat dining halls. Methods A previously validated exit survey was used to collect self-reported data from undergraduate students on foods and beverages they consumed during a single visit to two all-you-care-to-eat dining halls on the George Mason University Fairfax campus, during 4 weeks. (n = 468) Nutritional quality of each meal was evaluated on a 7-point rubric, according to the ‘Wellness Meal’ standards from the Partnership for a Healthier America: ≤700 kilocalories, ≤10% calories from saturated fat, ≤800 mg sodium, ≥2 ounces whole grains, ≥1 cup lowfat dairy, ≥ 1.75 cups fruits and vegetables, and ≥ 2 ounces lean protein. Results Of the maximum score of 7 on the meal nutritional quality rubric, 4 participants earned the highest score of 5, whereas 43, 150, 132, 88, and 51 participants had scores of 4, 3, 2, 1, and 0, respectively. The most commonly attained rubric standard was saturated fat, where 60% of participants consumed ≤ 10% calories from saturated fat and average consumption was 9.1% (± 5.4%) of calories. The least achieved rubric category was lowfat dairy, where only 2% of students consumed 1 cup equivalent, followed by only 9% of participants having consumed the 2 ounce equivalent of whole grains. Approximately one-third of students met calorie, lean protein, sodium, and fruit/vegetable standards. Conclusions Despite a wide variety of food options in the campus all-you-care-to-eat dining halls during the lunch hours, most undergraduate students consumed meals of subpar nutritional quality, with the vast majority meeting fewer than half the categories on the meal nutritional quality rubric. All-you-care-to-eat university dining halls may be a prime location for nutrition education and interventions.

AbstractObjectivesTo assess the nutritional quality of food aid delivered by food banks in France and to identify practical modifications to improve it.DesignNational-level data were collected for all food aid distributed by French food banks in 2004, and its nutrient content per 2000 kcal was estimated and compared with French recommendations for adults. Starting with the actual donation and allowing new foods into the food aid donation, linear programming was used to identify the minimum changes required in the actual donation to achieve the French recommendations.ResultsFrench food-bank-delivered food aid does not achieve the French recommendations for dietary fibre, ascorbic acid, vitamin D, folate, magnesium, docosahexaenoic acid, α-linolenic acid and the percentage of energy from saturated fatty acids. Linear programming analysis showed that these recommendations are achievable if more fruits, vegetables, legumes and fish were collected and less cheese, refined cereals and foods rich in fat, sugar and/or salt. In addition, new foods not previously collected are needed, particularly nuts, wholemeal bread and rapeseed oil. These changes increased the total edible weight (42%) and economic value (55%) of the food aid donation, with one-third of its edible weight coming from fruits and vegetables, one-third from staples, one-quarter from dairy products and approximately a tenth from meat/fish/eggs.ConclusionsImportant changes in the types and amounts of food collected will improve the nutritional quality of food-bank-delivered food aid in France. Such changes are recommended to improve the diets of deprived French populations.

Enzymatic browning affects the sensory and nutritional quality of fresh-cut apples and limits their shelf-life. Yerba mate ( Ilex paraguariensis), a plant widely consumed in South America as an infusion, could potentially be used in minimally processed fruits and vegetables as a natural additive to prevent browning, due to its high content of phenolic compounds with antioxidant capacity. The effects of the concentrations of ascorbic acid, citric acid, and yerba mate in an aqueous dipping solution on the instrumental color parameters, antioxidant capacity, and sensory quality of “Granny Smith” fresh-cut apples were modeled and the solution was optimized to obtain treated apples with maximum antioxidant capacity and minimum browning, without affecting the natural flavor of the fruits. The optimal composition obtained (1.2% yerba mate  + 0.9% citric acid + 1.0% ascorbic acid) increased the antioxidant capacity of the apples by 36%. The sensory acceptability test carried out on the “Granny Smith” fresh-cut apples treated with the optimal dipping solution showed that more than 78% of the surveyed consumers liked the color, flavor, and texture of the apples.

Present dietary recommendations for fruits and vegetables should be based on the bioavailability of essential nutrients at the time of optimum harvest. Few people, however, are fortunate enough to have available freshly harvested produce all year. With the development of improved postharvest technology, shelf life has increased dramatically in many parts of the world. How does the nutritional quality of fruits and vegetables change with increasing storage time, changes in storage atmosphere, different postharvest processes? Do these changes have an impact on dietary recommendations? Apples are capable of being stored for up to 12 months with properly managed temperature and storage atmosphere. Because information regarding this subject is lacking for apple (and many other fruits and vegetables), perhaps a model can be developed based on work with other commodities to help us understand the nutritional changes associated with different postharvest treatments.
