How Well Can We Control Dyslipidemias Through Lifestyle Modifications?

The role for lifestyle modifications to correct dyslipidemia(s) is reviewed. Dietary composition is crucial. Replacing saturated fat with MUFA or n-6 PUFA lowers plasma low-density lipoproteins (LDL) cholesterol and ameliorates the LDL/HDL ratio. Replacing saturated fat with carbohydrates has diverging effects due to the heterogeneity of carbohydrate foods. Diets rich in refined carbohydrates increase fasting and postprandial triglycerides, whereas the consumption of fiber-rich, low GI foods lowers LDL cholesterol with no detrimental effects on triglycerides. The role of polyphenols is debated: available evidence suggests a lowering effect of polyphenol-rich foods on postprandial triglycerides. As for functional foods, health claims on a cholesterol lowering effect of psyllium, beta-glucans and phytosterols are accepted by regulatory agencies. The importance of alcohol intake, weight reduction, and physical activity is discussed. In conclusion, there is evidence that lifestyle affects plasma lipid. A multifactorial approach including multiple changes with additive effects is the best option. This may also ensure feasibility and durability. The traditional Mediterranean way of life can represent a useful model

Effects of wholegrain cereal foods on plasma short chain fatty acid concentrations in individuals with the metabolic syndrome

Short chain fatty acids (SCFAs) derived from dietary fiber fermentation by gut microbiota have been identified as one of the mechanisms behind the association between habitual whole-grain intake and a lower risk of cardiometabolic diseases. The aims of the present work are: (1) to evaluate whether a whole-grain wheat-based diet may increase SCFAs concentration, and (2) to identify possible associations between SCFAs and metabolic changes observed after the nutritional intervention

The Possible Role of Nutraceuticals in the Prevention of Cardiovascular Disease

Cardiovascular diseases (CVDs) are the main causes of mortality and disability worldwide. Although the initial therapeutic approach to improve the main cardiovascular (CV) risk factors is based on nonpharmacological measures, mainly lifestyle modifications, compliance to recommendations is often poor and inadequate. Therefore, in recent years the use of several nutraceuticals, i.e., nutrients and/or bioactive compounds of plant or microbial origin with potentially healthful effects, has become widespread. However, to date, the scientific data on the possible benefits of the use of nutraceuticals are still inconclusive, due to the absence of adequately controlled intervention studies at least for some of them. Against this background, the scientific evidence derived from controlled intervention studies in relation to the effects of some nutraceuticals (i.e. fiber, phytosterols, soy products, red yeast rice, polyphenols and berberine) on the main CV risk factors (body weight, blood pressure, blood glucose levels and plasma lipids) in humans will be reviewed

Reduction in liver fat by dietary MUFA in type 2 diabetes is helped by enhanced hepatic fat oxidation

The aim of this work was to investigate hepatic lipid metabolic processes possibly involved in the reduction of liver fat content (LF) observed in patients with type 2 diabetes after an isoenergetic diet enriched in monounsaturated fatty acids (MUFAs)

Urine 8-isoprostane in relation to adiposity and insulin resistance in individuals at high cardiometabolic risk

Oxidative stress has been implicated in the pathogenesis of many conditions, including insulin resistance and obesity. However, in vivo data concerning these relationships are scarce and conflicting. Therefore, the aim of this study was to investigate the association of oxidative stress with abdominal adiposity and insulin resistance in individuals at high cardiometabolic risk
