Nutritional content of supermarket ready meals and recipes by television chefs in the United Kingdom: cross sectional study.

OBJECTIVES: To compare the energy and macronutrient content of main meals created by television chefs with ready meals sold by supermarkets, and to compare both with nutritional guidelines published by the World Health Organization and UK Food Standards Agency. DESIGN: Cross sectional study. SETTING: Three supermarkets with the largest share of the grocery market in the United Kingdom, 2010. SAMPLES: 100 main meal recipes from five bestselling cookery books by UK television chefs and 100 own brand ready meals from the three leading UK supermarkets. MAIN OUTCOME MEASURES: Number of meals for which the nutritional content complied with WHO recommendations, and the proportion of nutrients classified as red, amber, or green using the UK FSA's "traffic light" system for labelling food. RESULTS: No recipe or ready meal fully complied with the WHO recommendations. The ready meals were more likely to comply with the recommended proportions of energy derived from carbohydrate (18% v 6%, P=0.01) and sugars (83% v 81%, P=0.05) and fibre density (56% v 14% P<0.01). The recipes were more likely to comply with the recommended sodium density (36% v 4%, P<0.01), although salt used for seasoning was not assessed. The distributions of traffic light colours under the FSA's food labelling recommendations differed: the modal traffic light was red for the recipes (47%) and green for ready meals (42%). Overall, the recipes contained significantly more energy (2530 kJ v 2067 kJ), protein (37.5 g v 27.9 g), fat (27.1 g v 17.2 g), and saturated fat (9.2 g v 6.8 g; P<0.01 for all) and significantly less fibre (3.3 g v 6.5 g, P<0.01) per portion than the ready meals. CONCLUSIONS: Neither recipes created by television chefs nor ready meals sold by three of the leading UK supermarkets complied with WHO recommendations. Recipes were less healthy than ready meals, containing significantly more energy, protein, fat, and saturated fat, and less fibre per portion than the ready meals.

Evaluation of recipes for home-prepared diets for dogs and cats with chronic kidney disease.

OBJECTIVE: To evaluate recipes of diets recommended for animals with chronic kidney disease (CKD), compare nutritional profiles for those recipes to requirements for adult dogs and cats, and assess their appropriateness for the management of CKD. DESIGN: Evaluation study. SAMPLE: Recipes of 67 home-prepared diets promoted for use in dogs (n = 39 recipes) and cats (28) with CKD. PROCEDURES: Recipes were analyzed with computer software to determine calories, macronutrient calorie distribution, and micronutrient concentrations and were assessed for appropriateness for the management of CKD. RESULTS: Assumptions were required for the analysis of every recipe, and no recipe met all National Research Council nutrient recommended allowances (RA) for adult animals. Compared with RAs, concentrations of crude protein or at least 1 amino acid were low in 30 of 39 (76.9%) canine recipes and 12 of 28 (42.9%) feline recipes. Choline was most commonly below the RA in both canine (37/39 [94.9%]) and feline (23/28 [82.1%]) recipes; selenium (34/39 [87.2%] canine and 9/28 [32.1 %] feline recipes), zinc (24/39 [61.5%] canine and 19/28 [67.9%] feline recipes), and calcium (22/39 [56.4%] canine and 7/28 [25.0%] feline recipes) concentrations were also frequently below recommendations. The median phosphorus concentration in canine and feline recipes was 0.58 and 0.69 g/1,000 kcal, respectively. CONCLUSIONS AND CLINICAL RELEVANCE: Many problems with nutritional adequacy were detected, and use of the recipes could result in highly variable and often inappropriate diets. Many recipes would not meet nutritional and clinical needs of individual patients and should be used cautiously for long-term feeding.

[A survey on diet manuals in Italian hospitals]. / Indagine conoscitiva sui dietetici ospedalieri.

Hospital catering is very important to counteract the onset of malnutrition due to either undernutrition or overnutrition and for dietetic treatment. The aim of the study was to evaluate nutritional quality of the hospital dietetic manual used in some Italian hospitals and to analyze the role of the institutional Catering Service and of the Department of Clinical Nutrition. A survey has been carried out, in some Italian hospitals, using a questionnaire to point out the characteristics of hospitals, the typology of catering service, of the diets and of the staff of the Department of Clinical Nutrition. Only 22% of the hospitals has answered; three Italian regions (Umbria, Molise, Basilicata) are completely missing; -each hospital has a specific dietetic manual in most cases completely different from structure and nutritional quality point of view; the staff acting in this field is absolutely insufficient in term of numerousness and of professional typologies. Hospital in-patients are not homogeneous as for age, dietary needs and diseases, so it's necessary to treat them with an ad hoc nutritional intervention not established in advance in a dietetic manual; if from an organisation point of view it is necessary to have such a dietetic manual, it has to be based on nutritional guidelines and recommended dietary allowances.
