However, in general during these processes, phytate is not fully hydrolysed. To alleviate the aforementioned problems in the production of animal feeds, exogenous phytases (myo-inositol hexaphosphate phosphohydrolases) have been widely used. There is great potential, therefore, to use this class of enzymes in the processing and manufacturing of food for human consumption given the capacity to improve mineral bioavailability. This is seen as a way to reduce the risk of mineral deficiency in vulnerable groups including; childbearing women; strict vegetarians; babies consuming soy-based infant formulas; and the inhabitants of deve...

It is accepted that feeding habits are acquired through eating experiences and practices learned from the familiar and social context in early childhood. Besides the role of the social context, it is also assumed that familiar factors, both common family environment and genetic inheritance, have an important influence on food intake and eating behavior linked with childhood obesity. Research on food intake and childhood obesity has been traditionally focused on the amount and type of foods in the usual diet. However, it is an increasing interest to understand the link between eating behavior and obesity using questionnaires. There ar...

Thirty nine (39) BN female patients received cognitive behavioral treatment with a multidisciplinary team and had eating attitudes assessed by a questionnaire developed for this research. Frequencies of the attitudes assessed were compared at baseline, after 12 weeks and 24 weeks of treatment. After treatment, patients had less distorted beliefs about food, less guilty after eating "forbidden" foods and they felt more tranquil while eating outside home. Other negative behaviors, as dietary restriction, the desire of not eat, being angry when feeling hungry and using the food to relive stress, persisted. Eating attitudes of patients with BN are hard to be cha...

The beginning of food restriction occurs at earlier ages if there is an intense physical activity; body dissatisfaction is more intense among patients who practice exercise; and the presence of intense activity in anorexia nervosa usually precedes to the restrictive diet. The aim of this study was to evaluate the presence of exercise at the beginning of the eating disorder, and to analyze possible differences in the kind of exercise, according to age, sex and diagnostic subgroups. In order to evaluate the exercise 745 patients were assessed by the Eating Disorders Examination (EDE). The presenc...

We evaluated 180 teenage girls (12-17 years) in two public schools using food frequency questionnaires and a 24-hour food recall. According to the results, milk and cheese were this population's main calcium source. Milk was a food source in 60.5%, while 56.7% indicated that they eat cheese. On average, a once-a-day intake of one of these dairy products was observed in 1/4 of the group. Ice cream and pulses were secondary calcium sources. Yogurt, milk-made meals and beverages, green vegetables, fortified food and sardines were not components of these girls' food habits. The average calcium intake was 440 mg/d +/- 423...

In Venezuela, they are generally prepared at home and are consumed by adults, as soup or stew, while children eat them in very small quantities. In order to include legumes in the children's diet, the following work was done using cowpea (Vigna sinensis) as an complement of chicken in the preparation of a nutritionally balanced formula, adapted to the requirements of children. Several formulas were developed and three of them were selected based on their acceptability. In the first formula, the protein source was only of chicken. In the second formula, the chicken was partially substituted by cowpea, and in the third formula, the protein source was only made of cowpea. Other...

The main components of the fatty acid profile were oleic, palmitic, linoleic and palmitoleic acids. Fatty acids profile of microwaved avocado puree did not show significant changes (p < 0.05). Trans fatty acids were not detected. Microwaved avocado puree showed significant changes in its microstructure. Samples treated with microwaves for less than 40 s preserved the cells shape, causing only a minimal modification. On the other hand, microwave treated avocado puree using more than 40 s, showed a disruption of idioblast oil cells, releasing the oil contained on them.

Nevertheless, it is still not well known the role they play in infant nutrition or what the recommended intake would be for this population group. In recent years, there has been increased attention of the international scientific community towards polyamines, not only due to the important role they play in the cellular metabolism, but also to their possible implication in some diseases and during the development of the human organism. Bearing in mind that the content in polyamines of the infant formula is around tenfold less than in breast milk, it would b...

Today's specialists believe that the best way to lose weight is by cutting down on calories, essentialy in the form of fat. However, this paper will clarify that ketogenic diets are, from a physiological, biochemicale and practical point of view, a much more effective way of losing weight, since such diets provide metabolic advantages such as the capacity to preserve muscle mass, reduce appetite, to have a lower metabolic efficiency, produce a metabolic activation of thermogenesis and favour a greater fat loss even with a greater number of calories.

When rice is parboiled, the starch retrogrades with the formation of type 3-resistant starch (retrograded), which presents beneficial effects on the health, since it acts as a prebiotic. In the present study three types of rice were selected, with high, medium and low amylose contents, with the objective of evaluating the effects of conventional and parboiled rice on glycemia in Wistar rats. The samples with high and medium amylose contents were soaked for 6 h at 65 degrees C, and the low amylose sample for 7 h at 70 degrees C. The sample...

In this work, free acidity, pH, ash, nitrogen and water contents were measured, besides the total polyphenol content and the antioxidant capacity of the peel, the shell and the pulp of the fresh fruit and the processed guava pulp and jam. The highest phenolic content was found in the guava skin la (10.36 g/100 g skin) and the lowest in the jam (1.47 g/ 100 g jam), in dry weight. The antioxidant capacity of the skin was 10 times higher than that of the pulp, and the jam was twice that of the shell.

This ritual leads to a very restrictive diet and social isolation as a compensation. Orthorexics obsessively avoid foods which may contain artificial colours, flavours, preservant agents, pesticide residues or genetically modified ingredients, unhealthy fats, foods containing too much salt or too much sugar and other components. The way of preparation, kitchenware and other tools used are also part of the obsessive ritual. People with orthorexia often have a history or features in common with anorexic patients. They are very careful, detailed and tidy persons with an exagerated need for selfcare and protection. Women, adoles...

In the energy metabolism, the oxidation pathway and diet-induced thermogenesis are differentiated by diet macronutrients proportion. In this respect, the high-protein diet is the most thermogenic, compared to high-carbohydrate and high-lipid diets, while high-carbohydrate diet appears to increase the thermogenic effect more than high-lipid diet, but the studies are controversies. Towards energy intake, it can stimulate or inhibit the energy intake, according to the foods palatability, satiation and satiety degree, related to diet carbohydrate, protein and lipid content.

The main technological problem in the production of GFB is obtaining a gluten substitute that is both inexpensive and capable of retaining gas during bread fermentation and baking. The use of gelatinized starch as an alternative for gluten seems promising. In this project, rice bread was made using pregelatinized extruded rice flour as a gluten substitute. Pre-gelatinized rice flours (PRF) were manufactured in a single screw Brabender extruder, varying extrusion temperature (108-192 degrees C) and the moisture of the raw material (19.2 - 24.8%), and were ...
