Se estudiaron la variación estacional de la composición química proximal y el contenido energético de la carne de las pianguas Anadara tuberculosa y A. similis. Mensualmente, entre marzo de 2010 y febrero de 2011, se recolectaron de 15 a 20 ejemplares de cada especie. La composición proximal se determinó siguiendo la metodología recomendada por la Asociación Oficial de Químicos Analíticos (AOAC). El valor promedio de las proteínas de la carne de A. similis fue de 57.9 ± 7.2%, carbohidratos 25.6 ± 4.4%, cenizas 6.87 ± 0.23% y lípidos 9.2 ± 0.2%. El contenido calórico promedio fue de 5.3 ± 0.2 kcal/g. Para A. tuberculosa se calculó 61.6% de proteínas, 21.6% de carbohidratos, 8.8% de cenizas, 7.9% de lípidos; el valor calórico fue de 5.2 kcal/g. Se puede concluir que tanto A. tuberculosa como A. similis presentan valores nutricionales óptimos para el consumo humano, por su bajo contenido de grasa y su aceptable contenido proteico. Abstract The seasonal variation in proximate biochemical composition and energy content of Anadara tuberculosa and A. similis were studied between March 2010 and February 2011 on a monthly basis. Fifteen to twenty individuals of each species were collected monthly. The proximate composition was determined following the methodology recommended by the Association of Official Analytical Chemists (AOAC). The average value of meat protein in A. similis was 57.9 ± 7.2%, carbohydrate 25.6 ± 4.4%, ash 6.87 ± 0.23%, and lipids 9.2 ± 0.2%. The average caloric content was 5.3 ± 0.2 kcal/g. For A. tuberculosa the values were protein 61.6%, carbohydrate 21.6%, ash 8.8%, and lipids 7.9%. The caloric value was 5.2 kcal/g. It can be concluded that both A. tuberculosa and A. similis have optimal nutritional value for human consumption, due to their low lipid and high protein contents.

Dugesia Polychroa

The biochemical components of a population of Dugesia polychroa from Toronto Harbour showed, with the exception of total nitrogen, statistically significant variations over the time period studied (May 1971 through January 1972). The variation in biochemical composition was not totally correlated to changes in percentage biomass (mean individual weight), although the latter was itself indicative of events occurring in the population.Fluctuations in carbohydrate, lipid, and caloric content were highly correlated to changes occurring in percentage biomass during the period of reproduction and subsequent recruitment to the population. During this period a maximum in stored food reserves and energy content was observed. Before the winter these fractions increased to a second peak but at a disproportionately higher rate than that for percentage biomass. In both cases the caloric values were lower than the maximum physiological energy values.The changing nutritional state of Dugesia polychroa strongly supports the thesis that triclad population numbers are controlled by intraspecific competition for food, and, specifically shows that Dugesia polychroa exists, at least in Canada, in a state of relative starvation over the whole year.

The correct construction of agrophytocenoses on the slopes of the steppe trans-Urals helped to create maximum productivity. In the arid climate, the most productive were the double mixtures of alfalfa with brittle sitnik, wheatgrass is syd, providing an average of 41.6 and 40.2 quintals per hectare (c/ha) of hay, 32.1 and 31.0 GJ/ha OE (exchange energy per hectare), 4.5 and 4.3 quintals per hectare of boiled protein (c/ha) over 5 years. Single-species steppe ecotypes, brittle sieve and wheatgrass sieve in productivity slightly gave way to double components, providing respectively hay- 32.2 and 37.2 cents per hectare, exchange energy 22.2 and 25.7 GJ/ha, digested protein 1.93 and 2.53 c/ha. The enrichment of agrophytocense by the legume component allowed to increase the metabolic energy content to the level of 32.1 and 31.0-GJ/ha, digested protein to 4.5 and 4.3 quintals per hectare, which is 14 times the nutritional value of the metabolic energy, the digested protein is 10 times higher than the natural herb.

В исследовании участвовали 20 спортсменов-юниоров (мастера спорта и кандидаты в мастера спорта) в возрасте 17-18 лет и 10 добровольцев соответствующего возраста и интенсивности физической нагрузки. В результате исследований установлено, что суммарная калорийность потребленных за сутки продуктов в основном соответствовала энерготратам спортсменов обследованных групп. Соотношение белки/жиры/углеводы в суточном рационе спортсменов свидетельствует о недостаточной квоте углеводов в соответствии с формулой оптимального питания для юных спортсменов. При этом потребление добавленного сахара у спортсменов всех категорий превышало рекомендуемый уровень (10% от калорийности суточного рациона). The study involved 20 junior athletes (masters of sports and candidates for masters of sports) aged 17-18 and 10 volunteers of the corresponding age and intensity of physical activity. As a result of the research, it was found that the total calorie content of products consumed per day basically corresponded to the energy consumption of athletes in the surveyed groups. The ratio of protein / fat / carbohydrates in the daily diet of athletes indicates an insufficient carbohydrate quota in accordance with the optimal nutrition formula for young athletes. At the same time, the consumption of added sugar in athletes of all categories exceeded the recommended level (10% of the caloric content of the daily diet).

Abstract Although research has demonstrated the positive nutritional value and environmental benefits associated with edible insect consumption, several factors challenge the growth and development of the edible insect industry for human consumption in the US and Canada. Cultural and psychological factors account for much of the aversion US and Canadian consumers display. The absence of specific regulation also constitutes a structural barrier to more widespread production and sale of edible insects. Compared to the US, the European Union has a more developed edible insect industry and has enacted legislation that removes some of the barriers. As consumer awareness of the putative health benefits of edible insects increases, more comprehensive regulations may emerge to keep pace with the growth of this industry. Overall, a multi-disciplinary approach that addresses both benefits and barriers to consumption is needed to facilitate a robust market for edible insects in the US and Canada.

The Mediterranean green crabCarcinus aestuariiwas recorded in Tunisian waters several years ago. However, since its record in the Gulf of Gabes, no studies have been carried out about the spread of this crab. Because there is a lack of nutritional information concerning this species, this study aimed to characterize the chemical composition of hepatopancreas and gonads ofCarcinus aestuariiin view of potential health implication for consumers and to determine the seasonal nutritional quality of females and males taken separately for various size groups. In this study, a total of 1399 individuals were collected along the Sfax coast. The nutritional value of various edible parts ofCarcinus aestuariiwas evaluated, and gender differences in terms of edible yield and proximate composition, protein, mineral, lipid, and water content, were compared for season, age, and sex. The biochemical compositions were strongly influenced by sex, age, and seasons. The highest protein and lipid contents were detected in gonads and hepatopancreas of females. Autumn was the season with the highest protein content and lowest fat content. Therefore, people with particular diets constrains should consume the ovaries of females in autumn and it should moderate in winter. The hepatopancreas and gonads from Tunisian waters can be a good source of proteins and mineral.

In the present study we analysed the proximate-composition and caloric values of the preferred prey consumed by ribbonfish, Trichiurus lepturus L. 1758 (adult females), that are distributed in the inner continental shelf from northern Rio de Janeiro State, southeastern Brazil (~22ºS), assessing the potential of nutritional and energetic approach as a tool to understand the feeding selective pattern of this marine top carnivore. The preferred prey of this predator composed of fish co-specifics, Pellona harroweri, Chirocentrodon bleekerianus, Lycengraulis grossidens, Peprilus paru, squid Doryteuthis plei, and shrimp Xiphopenaeus kroyeri were collected from 2007 to 2010 for proximate-composition (water, protein, lipid, ash, and carbohydrate) and caloric value analyses. The correspondence analysis showed that protein is the main component in the prey species (61.32% of variance explained), standing out from the other nutrients. Lipid has the highest percentage related to L. grossidens, ash to X. kroyeri and carbohydrate to D. plei. The strong correlations between protein and caloric value (positive) and lipid and caloric value (negative) indicated that T. lepturus is attending its energy demand through the prey protein content. This work elucidated the feeding preference of adult females of T. lepturus in relation to nutritional and caloric content of their preferred prey. The species showed food selectivity to prey that provide more energy per ingested biomass, so that the feeding events can maximize the predator's caloric gain, which is obtained by a protein-based diet.
