Abstract
The search for more healthy alimentary habits has stimulated the study of new food sources. Edible mushrooms, such as the genus Agaricus , may be underscored. Current assay evaluates the dietary influence of diets supplemented with the mushroom Agaricus brasiliensis on the metabolic profile of lipids and glycemic behavior in rats. A trial with 28 male Wistar rats in 4 groups with 7 rats each was carried out during 32 days. Diets given to these groups were AIN-93 (CAS) for Group 1; AIN-93 with 1% cholesterol (CAS + COL) for Group 2; the same for Group 3 and 4, but supplemented with or without mushrooms [ (COG) and (COG + COL) respectively]. Analyses of all samples for cholesterol, triacylglycerols, hepatic cholesterol and hepatic lipids on the 32 nd day showed that Agaricus mushroom modified the lipid profile, reduced total cholesterol by 16% and triacylglycerols by 26.9% and increased HDL by 60.2%, coupled to reduction of lipid and cholesterol levels in the liver and a higher elimination of lipids in the stool. Glycemic curve decreased significantly between fifteen and sixty minutes in rats fed on Agaricus supplemented diets.
Highlights
The amount of dietary fiber in Brazilian diets has decreased significantly due to a reduction in the consumption of traditional fresh food, mostly those of vegetable origin
Since A. brasiliensis is a food matrix with potential consumption of dietary fiber in mixed diets, current study evaluated the influence of dietary consumption of a diet based on A. brasiliensis mushrooms on lipid metabolic profile and its effect on liver tissue architecture and on blood glucose in a model formed by Wistar rats
CAS + COL was based on AIN-93 with 1% cholesterol, whereas cogumelos sem (COG) + COL was prepared with A. brasiliensis with 1% cholesterol
Summary
The amount of dietary fiber in Brazilian diets has decreased significantly due to a reduction in the consumption of traditional fresh food, mostly those of vegetable origin. Mushrooms have great nutritional rates since they are quite rich in protein, with an important content of essential amino acids, B complex vitamins and minerals, coupled to poor fat concentration but with an excellent profile of fatty acids (Valverde, Hernández-Perez, & Paredes-López, 2015). Food matrix, such as Agaricus brasiliensis mushroom (A. brasiliensis), a native species of the Atlantic Rain Forest, has been commercially exploited, little is known on the true range of its properties (Henriques, Simeone, & Amazonas, 2008). Since A. brasiliensis is a food matrix with potential consumption of dietary fiber in mixed diets, current study evaluated the influence of dietary consumption of a diet based on A. brasiliensis mushrooms on lipid metabolic profile and its effect on liver tissue architecture and on blood glucose in a model formed by Wistar rats
