Total and Plant Protein Consumption: The Role of Inflammation and Risk of Non-Communicable Disease.

Background: Inflammatory cytokine levels are associated with Non-Communicable Diseases (NCDs) and can be influenced by a person’s macronutrient profile. This work aims to evaluate the relationship between the compliance with the age-specific recommended protein intake and the levels of inflammatory markers related to the risk of NCDs. Methods: The study participants included 347 participants (119 men and 228 women), ages 18 to 86 years.

Evaluation of adherence to Mediterranean diet and association with clinical and biological markers in an Italian population.

Objectives: The purpose of this study was to evaluate the overall diet quality of an Italian population through the use of the Mediterranean Diet Serving Score (MDSS) and its relation to clinical and biochemical nutritional markers.

Methods: The study was conducted on healthy participants ages 18 to 86 y living in central Italy. Adherence to the Mediterranean food pattern was evaluated by a semiquantitative food frequency, using the MDSS.

Distinctive modulation of inflammatory and metabolic parameters in relation to zinc nutritional status in adult overweight/obese subjects.

Overweight and obesity are associated with low grade of inflammation and chronic inflammatory response characterized by abnormal production and activation of some pro-inflammatory signalling pathways. Taking into account that obesity is the direct result of an imbalance between energy intake and energy expenditure, the nutritional factors in the diet, with particular focus on zinc, may play a pivotal role in the development of obesity-associated comorbidities. Considering the potential interactions among zinc nutritional status, inflammation, overweight/obesity and insulin secretion, the aim of the present work was to clarify the influence of zinc dietary intake on some metabolic, inflammatory and zinc status parameters in adult overweight/obese subjects.

Metabolic syndrome is not a risk factor for kidney dysfunction in obese non-diabetic subjects.

Objective: To investigate whether insulin resistance (IR) and the metabolic syndrome (MS) are associated with kidney dysfunction in obese non-diabetic (OND) subjects.

Methods And Procedures: Three-hundred and eighty (113M/267F; age = 41 +/- 14 years) OND subjects (BMI > or = 30 kg/m(2); range = 43 +/- 8 kg/m(2)) were studied. Anthropometric measures, blood pressure, fasting glucose, insulin, lipid profile, and serum creatinine were evaluated.

A functional variant of the adipocyte glycerol channel aquaporin 7 gene is associated with obesity and related metabolic abnormalities.

Aquaporin 7 (AQP7), the gateway protein controlling glycerol release, has recently emerged as a modulator of adipocyte metabolism. AQP7 knockout mice develop obesity and hyperglycemia. The contribution of AQP7 to these abnormalities in humans is unknown.

The common PPAR-gamma2 Pro12Ala variant is associated with greater insulin sensitivity.

Several genetic variants of peroxisome proliferator-activated receptor-gamma2 (PPAR-gamma2) have been identified, among which Pro12Ala, a missense mutation in exon 2, is highly prevalent in Caucasian populations. Up to now, conflicting results with regard to the association between this mutation and complex traits, such as obesity, insulin sensitivity and Type 2 diabetes, have been reported. We investigated the influence of the Pro12Ala polymorphism of PPAR-gamma2 on insulin sensitivity in a large Italian population sample, n=1215, in whom extensive clinical and biochemical analyses were performed.
