Qualidade de leites fermentados funcionais elaborados a partir de bactérias ácido-lácticas isoladas de queijo de coalho Quality of functional fermented milks produced by the use of lactic acid bacteria isolated from coalho cheese

Leites fermentados foram elaborados a partir de bactérias ácido-lácticas com propriedades funcionais, isoladas de queijo de coalho com e sem a adição de concentrado proteico de soro (CPS). Características físico-químicas, microbiológicas e sensoriais dos produtos elaborados foram analisadas durante 40 dias de estocagem sob refrigeração a 8-10ºC. Todos os leites fermentados elaborados, independentemente da adição de CPS e da cultura utilizada, apresentaram contagens adequadas de bactérias (>10(8)UFC/mL) durante todo o período de avaliação, o que garantiria seu possível potencial funcional. Leites fermentados por Lactobacillus acidophilus apresentaram melhor aceitação (PFermented milks were produced using whey protein concentrate (WPC) and potentially functional lactic acid bacteria, which were isolated from coalho cheese produced in. Physical-chemical, microbiological, and sensorial characteristics of the fermented milks were analyzed during 40 days under refrigeration at 8-10ºC. All products, irrespectively of WPC adding or culture used, showed appropriated bacterial counts (>10(8)CFU/mL) throughout the evaluation time, which would guarantee their functional potential. Lactobacillus acidophilus fermented milks presented better sensorial approval (P<0.05) when evaluated at 10-day storage; while Weissella confusa fermented milks presented lower acceptance (P<0.05) at 40-day storage. The association of Lactobacillus acidophilus and Weissella confusa or Lactobacillus acidophilus isolatedly, irrespectively of WPC adding, should be recommended for the industrial elaboration of novel functional fermented milks using Brazilian lactic cultures as starters

Implementation of a Brazilian Cardioprotective Nutritional (BALANCE) Program for improvement on quality of diet and secondary prevention of cardiovascular events: A randomized, multicenter trial

Background: Appropriate dietary recommendations represent a key part of secondary prevention in cardiovascular disease (CVD). We evaluated the effectiveness of the implementation of a nutritional program on quality of diet, cardiovascular events, and death in patients with established CVD. Methods: In this open-label, multicenter trial conducted in 35 sites in Brazil, we randomly assigned (1:1) patients aged 45 years or older to receive either the BALANCE Program (experimental group) or conventional nutrition advice (control group). The BALANCE Program included a unique nutritional education strategy to implement recommendations from guidelines, adapted to the use of affordable and regional foods. Adherence to diet was evaluated by the modified Alternative Healthy Eating Index. The primary end point was a composite of all-cause mortality, cardiovascular death, cardiac arrest, myocardial infarction, stroke, myocardial revascularization, amputation, or hospitalization for unstable angina. Secondary end points included biochemical and anthropometric data, and blood pressure levels. Results: From March 5, 2013, to Abril 7, 2015, a total of 2534 eligible patients were randomly assigned to either the BALANCE Program group (n = 1,266) or the control group (n = 1,268) and were followed up for a median of 3.5 years. In total, 235 (9.3%) participants had been lost to follow-up. After 3 years of follow-up, mean modified Alternative Healthy Eating Index (scale 0-70) was only slightly higher in the BALANCE group versus the control group (26.2 ± 8.4 vs 24.7 ± 8.6, P <.01), mainly due to a 0.5-serving/d greater intake of fruits and of vegetables in the BALANCE group. Primary end point events occurred in 236 participants (18.8%) in the BALANCE group and in 207 participants (16.4%) in the control group (hazard ratio, 1.15; 95% CI 0.95-1.38; P =.15). Secondary end points did not differ between groups after follow-up. Conclusions: The BALANCE Program only slightly improved adherence to a healthy diet in patients with established CVD and had no significant effect on the incidence of cardiovascular events or death. © 2019 The Author
