Fermented food: Should patients with cardiometabolic diseases go back to an early neolithic diet?

Fermentation has been used since the Early Neolithic period to preserve foods. It has inherent organoleptic and nutritive properties that bestow health benefits, including reducing inflammation and oxidative stress, supporting the growth of salutogenic microbiota, enhancing intestinal mucosal protection and promoting beneficial immunometabolic health effects. The fermentation of food with specific microbiota increases the production salutogenic bioactive compounds that can activate Nrf2 mediated cytoprotective responses and mitigate the effects of the 'diseasome of aging' and its associated inflammageing, which presents as a prominent feature of obesity, type-2 diabetes, cardiovascular and chronic kidney disease. This review discusses the importance of fermented food in improving health span, with special reference to cardiometabolic diseases.

May polydextrose potentially improve gut health in patients with chronic kidney disease?

Polydextrose (PDX) is a non-digestible oligosaccharide with a complex structure widely used in the food industry. Studies have shown many health benefits of polydextrose, including modulating the gut microbiota, improving the immune system, altering the lipid profile, and stimulating bowel function. Patients with chronic kidney disease (CKD) report gut dysbiosis, inflammation, dyslipidemia and constipation. These are major concerns that affect the quality of life. In this context, PDX can promote beneficial effects. However, little is known about PDX in CKD. This review discusses the possible beneficial effects of PDX on gut health for patients with CKD, particularly its impact on constipation.

Intoxicação aguda com sementes de Crotalaria spectabilis (Leg. Papilionoideae) em suínos / Acute poisoning with Crotalaria spectabilis (Leg. Papilionoideae) seeds in pigs

Relata-se necrose hepatocelular em suínos após consumo de ração que continha grãos de sorgo-granífero (Sorghum bicolor) acidentalmente contaminado com sementes de Crotalaria spectabilis. Morreram 76 suínos em quatro propriedades no município de Juscimeira, MT. Os sinais clínicos iniciaram-se 24-48 horas após o consumo da ração contaminada e foram caracterizados por depressão, letargia, apatia, inapetência, vômito, mucosas ictéricas ou pálidas, ascite, decúbito esternal, decúbito lateral com movimentos de pedalagem e convulsões, a evolução clínica foi de 48-60 horas seguida de morte. As Principais alterações macroscópicas foram fígado aumentado de tamanho com evidenciação do padrão lobular, ascite e hidrotórax com líquido de coloração amarelo avermelhado contendo filamentos com aspecto de fibrina, linfonodos aumentados e edema pulmonar interlobular. A doença foi reproduzida utilizando-se 16 suínos divididos em seis grupos que receberam sementes de C. spectabilis em diferentes doses. Necrose hepatocelular ocorreu em sete suínos, sendo dois que receberam doses diárias 2,5g/kg e cinco que receberam doses únicas de 5,0 e 9,5g/kg. Dez doses diárias de 0,5 e 1,25g/kg causaram fibrose hepática.

Hepatocellular necrosis are reported in swine after consumption of diets containing grains of "sorgo-granífero" (Sorghum bicolor) accidentally contaminated with Crotalaria spectabilis seeds in the municipality of Juscimeira, MT. Clinical signs began 24-48 hours after consumption of contaminated ration and were characterized by depression, lethargy, apathy, loss of appetite, vomiting, pale or jaundiced mucous membranes, ascites, lateral recumbency, the lateral position with paddling and convulsions, clinical outcome was 48-60 hours followed by death. 76 pigs died in four properties. The main gross lesions were liver increased in size and lobular illustration with red-brown central areas interspersed with yellowish areas, ascites and hydrothorax with reddish-yellow liquid containing filaments with aspect of fibrin, enlarged lymph nodes and interlobular pulmonary edema. The disease was experimentally reproduced with 16 pigs divided into six groups that received seeds of C. spectabilis in different doses. Hepatocellular necrosis occurred in seven pigs, two of which received daily doses of 2.5g/kg and five who received single doses of 5 and 9.5g/ kg. Ten daily doses of 0.5 and 1.25g/kg caused liver fibrosis.
