Immunonutrition: future perspective in neurodegenerative disorders.

The relevance of lifestyle, including diet and exercise, has been associated with improved learning and memory capacity, delayed age-related cognitive decline, and a reduced risk of neurodegeneration. Most neurodegenerative diseases are defined as complex multifactorial disorders in which genetic and environmental factors greatly contribute to their onset. Although inflammatory cells produce reactive oxygen species (ROS), oxidative stress itself might exert pro-inflammatory effects and an uncontrolled response could lead to a state of chronic inflammation.

Pomace Olive Oil Concentrated in Triterpenic Acids Restores Vascular Function, Glucose Tolerance and Obesity Progression in Mice.

Pomace olive oil, an olive oil sub-product, is a promising source of bioactive triterpenoids such as oleanolic acid and maslinic acid. Considering the vascular actions of pomace olive oil and the potential effects of the isolated oleanolic acid on metabolic complications of obesity, this study investigates for the first time the dietary intervention with a pomace olive oil with high concentrations of the triterpenic acids (POCTA), oleanolic and maslinic acid, during diet-induced obesity in mice. The results demonstrate that obese mice, when switched to a POCTA-diet for 10 weeks, show a substantial reduction of body weight, insulin resistance, adipose tissue inflammation, and particularly, improvement of vascular function despite high caloric intake.
