Insect gut microbes have been shown to provide nutrients such as essential amino acids (EAAs) to their hosts. How this symbiotic nutrient provisioning tracks with the host's demand is not well understood. In this study, we investigated microbial essential amino acid (EAA) provisioning in omnivorous American cockroaches (Periplaneta americana), fed low-quality (LQD) and comparatively higher-qual...

Objective Infertility is one of the most common challenges that women of reproductive age would encounter today. The maternal nutritional status is a particularly important determinant of oocyte quality and embryonic growth. Studies on whether the overall diet can affect reproductive outcomes in infertile women are few. So this study was conducted to assess the relationship between dietary patt...

an experiment was conducted to evaluate the effect of dietary crude protein and methionine levels on quality and quantity of egg production. fifteen diets formulated with 3 levels of protein (13, 14 and 15%) and 5 levels of methionine (0.25, 0.28, 0.31, 0.34 and 0.37%) and fed to 420 birds in a 3×5 factorial arrangement. each diet was randomly fed to 4 replicates of 7 birds each and fed for 3 p...

Dietary protein intake and specifically the quality of the protein in the diet has become an area of recent interest. This study determined the relationship between the amount of quality protein, carbohydrate, and dietary fat consumed and the amount of times the ~10 g essential amino acid (EAA) threshold was reached at a meal, with percent central abdominal fat (CAF). Quality protein was define...

BACKGROUND There is limited knowledge about dietary quality among the adult population in low- and middle income countries (LMICs). This study aims to describe dietary quality among the adult Saharawi refugee population and to investigate whether dietary quality is associated with socioeconomic status. METHODS In 2014, a cross-sectional survey was carried out in the Saharawi refugee camps, Al...

The primary aim of this study was to assay the influence of dietary Ca sources and levels on performance, egg quality indices, and selected blood variables of laying hens. A total of 192 Bovanz commercial layers were distributed to 6 dietary treatment groups with 4 replicates and 8 birds in each replicate. The experimental diets were iso-caloric and iso-nitrogenous, but they were different in t...

Background: Beneficial effects of omega-3 polyunsaturated fatty acids (PUFAs) on the male fertility are widely described in the literature. However, there is little information about the effect of dietary n-3/n-6 ratios and Vit E on the male reproduction. The aim of this study was to evaluate the influence of dietary PUFAs on the rat sperm characteristics after eight weeks oil consumption. Mate...

BACKGROUND A number of dietary quality indices (DQIs) have been developed to assess the quality of dietary intake. Analysis of the intake of individual nutrients does not reflect the complexity of dietary behaviours and their association with health and disease. The aim of this study was to determine the dietary quality of individuals with type 2 diabetes mellitus (T2DM) using a variety of vali...

Recently, the concept of food-based dietary guidelines has been introduced by WHO and FAO. For this concept, several assumptions were necessary. The validity and potential consequences of some of these assumptions are discussed in this paper on the basis of the Dutch National Food Consumption Surveys. The topics were interrelationships among dietary characteristics, nutrient density, diets in a...
