Food Value of Mealworm Grown on Acrocomia aculeata Pulp Flour

Insects have played an important role as human food throughout history, especially in Africa, Asia and Latin America. A good example of edible insects is the mealworm, Tenebrio molitor Linnaeus, 1758 (Coleoptera, Tenebrionidae), which are eaten in Africa, Asia, the Americas and Australia. This species is easily bred in captivity, requiring simple management. The bocaiuva (Acrocomia aculeata (Jacq.) Lodd) is an abundant palm tree found in the Brazilian Cerrado, providing fruits with high nutritional value. The aim of this work was to determine the chemical composition of T. molitor grown in different artificial diets with bocaiuva pulp flour. The nutritional composition, fatty acid composition, antioxidant activity, trypsin activity and anti-nutritional factors of larvae were analyzed. The results showed that mealworms grown on artificial diet with bocaiuva are a good source of protein (44.83%) and lipid (40.45%), with significant levels of unsaturated fatty acids (65.99%), antioxidant activity (4.5 μM Trolox/g of oil extracted from larvae) and absence of anti-nutritional factors. This study indicates a new source of biomass for growing mealworms and shows that it is possible to breed mealworms in artificial diet with bocaiuva flour without compromising the nutritional quality of the larvae.

“…Os resultados são semelhantes aos encontrados por Farias et al [14] que, ao analisarem a composição nutricional de dietas da moda publicadas em revistas, observaram uma média de valor energético de 1182 kcal/dia. Outros estudos semelhantes também encontraram valores calóricos abaixo dos recomendados [15][16][17].…”

“…Sabe-se que uma dieta inadequada pode resultar em deficiência tanto de macronutrientes quanto de micronutrientes, podendo prejudicar o funcionamento de órgãos, sistemas ou processos metabólicos do corpo humano [14][15][16][17][18][19]. Nas mulheres em idade fértil essas deficiências podem causar danos ainda maiores, considerando-se a função reprodutiva dessa faixa etária e as graves repercussões que podem advir da carência de determinados nutrientes [20][21][22][23][24][25][26].…”

ABSTRACT Aims:To nutritionally analyze diets published in a women's magazine and compare them with current dietary recommendations for macronutrient and micronutrient intake by adult women. Methods: Twenty-four issues published in 2013 and 2014 by women's magazine with the largest circulation in that period were selected, and the weight-loss diets therein were assessed. The nutritional composition was calculated by the Avanutri ® software and compared with the current recommendations from the Institute of Medicine for macronutrients and micronutrients. The diets were divided into two groups: large caloric restriction (≤ 1,100 kcal) and slight caloric restriction (> 1,100 kcal).Results: Twenty diets were analyzed, with an average caloric value of 1,227.83±261.54 kcal. All diets were deficient in vitamin D (mean of 2.09±1.16, folic acid (mean of 109.26±41.19), iron (mean of 11.35±3.06), calcium (mean of 532.23±133.56), and zinc (mean of 4.23±2.11). When both groups were compared, diets with large caloric restriction had lower concentrations of vitamin C (p=0.011), iron (p=0.051), calcium (p=0.022), and zinc (p=0.033). Most diets contained the recommended amount of macronutrients, but all of them were lacking in fibers. Most diets with inappropriate amounts of macronutrients and micronutrients were in the large caloric restriction group. Conclusions: Most diets had a deficient supply of energy and nutrients, especially vitamins and minerals that are important for women of childbearing age. Diets with large caloric restriction often contained inappropriate nutritional values. This result reinforces the importance that diets be individualized and monitored by a qualified professional.

“…The macronutrients in the low-carb diet were below the recommended percentages, except for the lipids, as the principle of this diet recommends carbohydrate restriction and not lipid restriction [10,11]. Carbohydrate restriction promotes the mobilization of muscle and liver glycogen reserves, a metabolic process that leads to water uptake.…”

ObjectiveTo analyze quantitatively the diets available on blogs and websites. MethodsThe following 15 diets were analyzed: low-carb diet, gluten-free diet and intermittent fasting diet using the Virtual Nutri software program. The nutrients analyzed were as follows: carbohydrates, fi bers, proteins, lipids, iodine, sodium, calcium, magnesium, iron, zinc, manganese, phosphorus, selenium, vitamins A, C, B6, B12, D, niacin, and folate. The nutrient values were compared with the Dietary Reference Intake recommendation for adults between the ages of 19-50 years. The macronutrient adequacy percentage was based on a 2000-kcal diet for a healthy life, as recommended by the World Health Organization. ResultsIt was observed that most of the composition of macro and micronutrients was lower than the one established by the World Health Organization and the Dietary Reference Intake recommendation for adults between the ages of 19-50 years. ConclusionLong-term dieting can be a risk factor for several defi ciency diseases and may endanger the health of individuals.
