Depending on the type of user, it is possible that there are many purposes for retrieval of foods from a computerised nutrient data base. A Dietitian on one occasion may need to come up with a qualified assessment of foods in the process of diet construction so that the process of balancing nutrients for the diet takes less time. On another occasion the dietitian may want to recommend a food for a client which requires knowledge of the standing of that food with respect to one or more of its contents of nutrients. A dietitian is not able to memorise all the foods and their nutrient content. Moreover if the number of foods is many then the dietitian's ability to refer foods according to their standing may become impossible. Ranking foods with respect to their nutrient contents within a reasonable number could be very useful for dietetic purposes. This paper discusses the processes of ranking of foods as high, medium and low only, and proposes guidelines which can be referred to for rejecting inappropriate ranking schemes of foods. The proposed guidelines are based on the results of experiments which are included in this paper.

Npk Fertilization

Adequate nutrient levels in plants vary according to the species or clone, age and management practice. Therefore, adjustments of the nutrient solution are often necessary according to the plant material for multiplication. This study aimed to evaluate the influence of NPK fertilization on production and leaf nutrient contents of eucalyptus cuttings in nutrient solution. The study was conducted from November 2008 to January 2009 in a greenhouse. The experimental design was completely randomized fractional factorial (4 x 4 x 4)½, with a total of 32 treatments with three replications. The treatments consisted of four doses of N (50, 100, 200 and 400 mg L-1) as urea, P (7.5, 15, 30 and 60 mg L-1) in the form of phosphoric acid and K (50, 100, 200 and 400 mg L-1) in the form of potassium chloride in the nutrient solution. Only the effect of N alone was significant for the number and dry weight of minicuttings per ministump, with a linear decreasing effect with increasing N levels. The highest number of cuttings was obtained at a dose of 50, 7.5 and 50 mg L-1 of N, P and K, respectively.

Fish oil is a source of omega 3 fatty acids, especially DHA and EPA having health benefits, such as prevention of heart disease and improvement of brain development including vision. However, these components are susceptible to oxidative damage and its fishy smell may affect consumer acceptance. This study aimed to immobilize this oil in rice flour usually prepared for "sumsum" porridge, a traditional meals for children or mother. Some of type of polymer are mixture with oil and was sprayed on to the rice flour to ensure the oils were coated with these polymer. Hedonic test of "sumsum" porridge was performed for acceptability for 4% fish oil and 4% equal weight of polymer malto-dextrin and soy flour. The nutrient contents were also presented. The nutrient content of the sample could be use as food supplement for under-five year children and his mother. Keywords: fish oil, applement, omega 3 fatty acids

Abstract Objectives This study concerns how the description of foods on restaurant menus relates to their nutrient content as disclosed on company websites. We aimed to test halo effects, regarding how claims about some desirable features might be associated with the presence of other attributes. Methods We used item descriptions and nutrient data for food items (n = 92,949) at the top-selling restaurant chains (n = 92) from 2012 through 2017 in the United States, compiled by the MenuStat project. We classified items into 4 types (mains, appetizers, desserts, sides) and claims into 3 groups using 29 search terms based on consumer interests in health (e.g., “nutritious”), product sourcing (e.g., “local” or “organic”), and vegetal items (vegetarian or vegan). Nutrient data focus on 4 dietary recommendations to limit sodium (mg), trans-fat (g) and saturated fats (% of energy), and to increase fiber (g). We also report calories per item (kcal) and its share from carbohydrates, protein and total fat (%). We used multiple regression to test whether nutrient content was associated with menu claims, controlling for year and restaurant brand, the item being marked as “shareable”, on a kid's menu, or regional and limited-time offerings. Methods and hypotheses were preregistered on As-Predicted.com. Results Contrary to our prediction, nutrient content was more often aligned with U.S. dietary guidelines when their description did include claims. With 3 claim types, 4 food types and 4 recommendations we test 48 possible cases. In 25 (52%) we found alignment between claims and nutrient recommendations, e.g., main dishes with health-related claims had 2% less calories from saturated fat (P < 0.01) and 142 mg less sodium (P < 0.01). In 3 of 48 cases (7%), claims were contrary to recommendations, all of which were desserts with sourcing claims which had more sodium, more trans-fat and more saturated fat than other desserts (all P < 0.01). In 20 of 48 cases (42%) there was no significant difference between items with and without claims. Conclusions Items described as vegetarian/vegan or with sourcing and health claims had nutrient contents that were more often aligned with dietary guidelines than other items. Menu labeling that communicates meal content more directly, such as nutrient fact panels, could inform choice and build trust in restaurant meals. Funding Sources None.

Sweet Foods

Taste is expected to represent a food's nutrient content. The objective was to investigate whether taste acts as nutrient-sensor, within the context of the current diet, which is high in processed foods. Intensities of the five basic tastes of fifty commonly consumed foods were rated by nineteen subjects (aged 21·0 (sd 1·7) years, BMI 21·5 (sd 2·0) kg/m2). Linear regression was used to test associations between taste and nutrient contents. Food groups based on taste were identified using cluster analysis; nutrient content was compared between food groups, using ANOVA. Sweetness was associated with mono- and disaccharides (R2 0·45, P < 0·01). Saltiness and savouriness were correlated, with r 0·92 (P < 0·01) and both were associated with Na (both: R2 0·33, P < 0·01) and protein (R2 0·27, P < 0·01 and R2 0·33, P < 0·01, respectively). Cluster analysis indicated four food groups: neutral, salty and savoury, sweet–sour and sweet foods. Mono- and disaccharide content was highest in sweet foods (P < 0·01). In salty and savoury foods, protein content (P = 0·01 with sweet–sour foods, not significant with neutral or sweet foods) and Na content (P < 0·05) were the highest. Associations were more pronounced in raw and moderately processed foods, than in highly processed foods. The findings suggest that sweetness, saltiness and savouriness signal nutrient content, particularly for simple sugars, protein and Na. In highly processed foods, however, the ability to sense nutrient content based on taste seems limited.

Improved Model

An improved model for estimating nutrient contents of the commercial portion of tree boles was developed for four boreal tree species (Populus tremuloides Michx., Betula papyrifera Marsh., Picea glauca (Moench) Voss, and Abies balsamea (L.) Mill.). This model considers the spatial pattern of variation of nutrient concentrations inside the bole and its relationships with tree size. For all species-nutrient combinations, no significant pattern was found for vertical variations in nutrient concentrations, while two types of nonlinear models, using distance from the tree periphery as the independent variable, fit the pattern of horizontal (or radial) variations. These patterns of variability were used to estimate the global nutrient concentration of the bole by using mathematical integration. The values obtained with this method were generally lower, especially for large stems, than values obtained with traditional methods that do not consider the variability of nutrient concentrations inside the bole. This improved model would permit better estimates of the amounts of nutrients lost in biomass upon forest harvesting, as well as internal cycling of nutrients within the bole.
