ABSTRACT

Low-grade metabolic acidosis is a condition characterized by a slight decrease in blood pH, within the range considered normal, and feeding is one of the main factors that may influence the occurrence of such a condition. The excessive consumption of acid precursor foods (sources of phosphorus and proteins), to the detriment of those precursors of bases (sources of potassium, calcium, and magnesium), leads to acid-base balance volubility. If this condition occurs in a prolonged, chronic way, low-grade metabolic acidosis can become significant and predispose to metabolic imbalances such as kidney stone formation, increased bone resorption, reduced bone mineral density, and the loss of muscle mass, as well as the increased risk of chronic diseases such as type 2 diabetes mellitus, hypertension, and non-alcoholic hepatic steatosis. Considering the increase in the number of studies investigating the influence of diet-induced metabolic acidosis on clinical outcomes, this review gathers the available evidence evaluating the association of this disturbance and metabolic imbalances, as well as related mechanisms. It is necessary to look at the western dietary pattern of most countries and the increasing incidence of non-comunicable diseases for the balance between fruit and vegetable intake and the appropriate supply of protein, mainly from animal sources, so that it does not exceed the daily recommendations.

ABSTRACT

O presente estudo objetivou avaliar a qualidade proteica de hambúrgueres elaborados com quitosana e farinha de linhaçadourada desengordurada, por meio da resposta biológica em ratos. Foram utilizados ratos machos Wistar, alimentados porum período de 28 dias com as seguintes dietas experimentais: dieta aproteica, dieta com caseína e dietas-testes, onde acaseína foi substituída por farinha de hambúrguer tradicional (HT), farinha de hambúrguer com quitosana (HQ) e farinhade hambúrguer com farinha de linhaça dourada desengordurada (HLD). Foram avaliados o ganho de peso, o consumoalimentar, a quantidade de proteína ingerida, o coeficiente de qualidade proteica (PER), a razão protéica líquida (NPR) e adigestibilidade verdadeira (DV) dos animais alimentados com diferentes tipos de farinhas de hambúrguer. O ganho de pesofoi maior no grupo HT. O PER variou de 2,33 (caseína) a 1,94 (HQ) e o NPR de 2,65 (caseína) a 2,22 (HQ). A DV para asfarinhas de hambúrguer foram menores que 90%. Verificou-se que os hambúrgueres com fibras oferecidos aos animais emforma de farinhas apresentaram menor eficiência em relação a caseína. Entretanto possuem uma boa qualidade proteica,fato que possibilita a inclusão dos mesmos em dietas de indivíduos sadios.


This study aimed to evaluate the protein quality of hamburgers made with chitosan and golden flaxseed meal defatted throughbiological response in rats. Male Wistar rats were fed for 28 days with the following experimental treatments: protein dietand diets diet with casein-tests where casein was replaced by traditional burger meal (HT), burger meal with chitosan (HQ)and burger meal with golden defatted flaxseed meal (HLD). Weight gain was evaluated, food consumption, the amountof protein intake, the protein quality ratio (PER), Net protein ratio (NPR) and true digestibility (DV) of the animals fed withdifferent types of flour burger . Weight gain was higher in the HT group. The PER ranged from 2.33 (casein) to 1,94 (HQ)and the NPR 2,65 (casein) to 2,22 (HQ). The DV for hamburger meal was lower than 90%. It was found that the burgerswith fibers offered to animals in the form of flour showed lower efficiency compared to casein. However they have a goodprotein quality, a fact that allows their inclusion in diets of healthy individuals.

ABSTRACT

Evidences suggest that a diet rich in fruits and vegetables decreases the risk of several degenerative diseases. The world population aging process requires more efforts to delay the onset of such diseases. Therefore, the inclusion of functional foods in the diet is an excellent strategy to improve the quality of life. Brazil is the world`s largest producer of orange, which provides many health benefits. The purpose of this paper is to review the recent literature in order to demonstrate the benefits provided by the inclusion of orange in the diet as a preventive measure for many diseases. Based on the properties demonstrated in this review, a discussion about the inclusion of orange in the category of functional foods is proposed.

El envejecimiento de la población mundial exige más esfuerzos para retardar la manifestación de esas enfermedades. Por lo tanto, la inclusión de alimentos funcionales en la dieta es una excelente estrategia para mejorar la calidad devida de poblaciones. La naranja, que encuentra en Brasil su mayor productor mundial, tiene varias propiedades benéficas para la salud. El propósito de este trabajo fue revisar la literatura reciente para demostrar los beneficios de la inclusión de naranja en la dieta como medida preventiva de una serie de enfermedades. Con base en las propiedades demostradas e nesta revisión, se propone discutir la inclusión de la naranja en la categoría de alimentos funcionales.

O envelhecimento da população mundial requer mais esforços no sentido de retardar o aparecimento deste tipo de doença. Portanto, a inclusão de alimentos funcionais na dieta é uma excelente estratégia para melhorar a qualidade de vida da população. A laranja, fruta que tem o Brasil, como o seu maior produtor mundial, possui diversas propriedades benéficas à saúde. O propósito deste artigo é revisar a literatura recente demonstrando os inúmeros benefícios da inclusão da laranja na dieta, como medida preventiva de uma série de doenças. Com base nas propriedades demonstradas nesta revisão, propõe-se a discussão sobre a inclusão da laranja na categoria de alimento funcional.
