The purpose of this study is to investigate the effect of a 15-week dietary intake of cactus flour on metabolic parameters, body weight and dietary intake of rats.

Male Wistar rats were divided into four experimental groups (n = 8-10): control or westernized diets added or not of cactus flour. The following parameters were evaluated during the period of dietary manipulation: body weight, food intake, glycemic and lipid profile (oral glucose tolerance test, metabolic parameters, hepatic and muscular glycogen dosage), visceral and body fat (relative weight to body weight). Data were analyzed using Graphpad Prism®5, p = 0.05.

Animals fed on a Western-style diet together with flour cactus presented lower weight gain (335.7 ± 20.0, p = 0.05) over the evaluated period, even when the volume of food intake was not different among the groups. The addition of cactus flour to a Western-style diet appears to lower glucose levels at 30 and 60 min (p = 0.05), as shown in the glucose tolerance curve. There was a downward trend does fat stores, cholesterol levels and triglycerides. Therefore, it was concluded that this addition cactus flour is effective even when the diet is hyperlipidic, demonstrating its ability to attenuate risk parameters for the occurrence of metabolic syndromes such as sub fraction high cholesterol levels and glucose tolerance.

The addition of functional foods to diets may work to improve the harmful effects of this type of diet. Opuntia ficus indica has high nutritional value and has hypoglycemic and hypolipemic properties besides being antioxidant.

This study aims to analyse the essential characteristics for the success of social projects developed with undergraduate students of higher education institutions (HEIs).

A case study was conducted to verify the main characteristics of projects in a social entrepreneurship initiative. These features were used to perform a survey with experts to understand which of these items are essential for social projects success, through Lawshe’s method.

Of the ten items evaluated, two were considered essential by the experts: “Proper alignment between project scope and actual local community needs” and “Good level of interaction between students participating in the project and the local community”.

These findings can be useful for professors and coordinators to prepare future projects in HEIs. They may also be advantageous for researchers who may use them as a starting point for future studies.

The novelty of this study is the methodological approach used: a case study of projects in a social entrepreneurship initiative in a relevant Brazilian university; and a Lawshe’s method analysis of responses of experts in social projects developed in HEIs. The findings can greatly contribute to the debates in this field. No similar research was found in the literature.
