Fatty Acids, Antioxidants and Physical Activity in Brain Aging Abstract: Polyunsaturated fatty acids and antioxidants are important mediators in the central nervous system. Lipid derivatives may control the production of proinflammatory agents and regulate NF-κB activity, microglial activation, and fatty acid oxidation; on the other hand, antioxidants, such as glutathione and ascorbate, have been shown to signal through transmitter ...

Early nutrition and ageing: can we intervene? Abstract Ageing, a complex process that results in progressive decline in intrinsic physiological function leading to an increase in mortality rate, has been shown to be affected by early life nutrition. Accumulating data from animal and epidemiological studies indicate that exposure to a suboptimal nutritional environment during fetal life can have long-term effects on adult health. In ...

Causes, Consequences and Public Health Implications of Low B-Vitamin Status in Ageing Abstract: The potential protective roles of folate and the metabolically related B-vitamins (vitamins B12, B6 and riboflavin) in diseases of ageing are of increasing research interest. The most common cause of folate and riboflavin deficiencies in older people is low dietary intake, whereas low B12 status is primarily associated with food-bound malabso...

Aging Gut Microbiota at the Cross-Road between Nutrition, Physical Frailty, and Sarcopenia: Is There a Gut–Muscle Axis? Abstract: Inadequate nutrition and physical inactivity are the mainstays of primary sarcopenia–physiopathology in older individuals. Gut microbiota composition is strongly dependent on both of these elements, and conversely, can also influence the host physiology by modulating systemic inflammation, anabolism, ...

Vitamin D Supplementation and Non-Alcoholic Fatty Liver Disease: Present and Future Abstract: Non-alcoholic fatty liver disease (NAFLD) is the most common chronic hepatic disease throughout the Western world and is recognized as the main cause of cryptogenic cirrhosis; however, the identification of an effective therapy for NAFLD is still a major challenge. Vitamin D deficiency is a wide-spread condition which reaches epidemic proporti...

Translational Aspects of Diet and Non-Alcoholic Fatty Liver Disease Abstract: Non-alcoholic fatty liver disease (NAFLD) is a spectrum of diseases ranging from simple steatosis without inflammation or fibrosis to nonalcoholic steatohepatitis (NASH). Despite the strong association between dietary factors and NAFLD, no dietary animal model of NAFLD fully recapitulates the complex metabolic and histological phenotype of the disease, although ...

The role of nutraceuticals for the treatment of non-alcoholic fatty liver disease Abstract Non-alcoholic fatty liver disease (NAFLD) represents the most common chronic liver disease. It is characterized by a wide spectrum of hepatic changes, which may progress to liver fibrosis and to cirrhosis. NAFLD is considered as the hepatic component of the metabolic syndrome but mechanisms underlying the onset and progression of NAFLD are still ...
