Effects of the whole seed and a protein isolate of faba bean (Vicia faba) on the cholesterol metabolism of hypercholesterolaemic rats

The aim of the present work was to analyse the hypocholesterolaemic efficiency of a Vicia fabaprotein isolate in relation to the intact legume. In addition, the mechanisms underlying the effects of this isolate were investigated. Hypercholesterolaemic rats were divided into three groups n10 3 and fed high-fat diets rich in cholesterol-containing casein, whole seeds of Vicia faba or the protein isolate of faba beans as protein source, for 2 weeks ad libitum. The protein isolate was prepared by isoelectric precipitation and spray dried. Analyses of serum, liver and faeces, as well as of the activity of hepatic 3-hydroxy-3-methylglutaryl (HMG)-CoA reductase, were assessed by enzymatic methods. The rats fed on Vicia faba diets showed significantly lower body weights and energy intakes than rats fed on casein diets. The wholeseed diet induced a significant reduction in plasma triacylglycerol. Feeding rats on diets containing faba bean seeds, or the protein isolate, induced a significant decrease in plasma (LDL+VLDL)-cholesterol but not in HDL-cholesterol. Hepatic cholesterol and triacylglycerol were also reduced. The hypocholesterolaemic effects of Vicia faba were not the result of a reduction in cholesterol synthesis as assessed from HMG-CoA reductase activity, but the result of an increase in steroid faecal excretion. The faba bean-protein isolate obtained under our experimental conditions was useful in improving the metabolic alterations induced by feeding with a hypercholesterolaemic diet compared with casein. The effectiveness of the whole seeds was higher than that of the protein isolate

Resource Guide for Mental Health Providers working with Latinos

A resource guide for mental health practitioners working with Latino immigrant clients was developed based on the personal realization by the author of the need for such a guide. The development of the resource was informed by the dialog with graduate students, trainees, MFTI and MFT working within the Latino immigrant population. Review of the literature was used to understand the psychosocial stressors of clients from Latin America. The resource guide offers clinicians culturally adapted interventions, psycho educational handouts (provided in Spanish and English). The author’s hope is that resource guide may be advantageous for mental health providers working with Latino population. The resource guide may offer culturally appropriate interventions in order to enhance cultural sensitivity, thus leading to a stronger therapeutic alliance
