Background: High-fat meals induce postprandial inflammation. Resveratrol is a polyphenol known to prevent comorbidities associated with cardiovascular disease and exerts an anti-inflammatory action. There is also an increasing body of evidence supporting the role of curcumin, a polyphenol from the curcuminoid family, as a modulator of proinflammatory processes. Objective: The objectives of this study were to investigate the following: 1) the bioavailability of resveratrol consumed in combination with curcumin after consumption of a high-fat meal; and 2) the acute combined effects of this combination on the postprandial inflammatory response of subjects with abdominal obesity...

As the influence of diet on health may take place over a period of decades, there is a need for biomarkers that help to identify those aspects of nutrition that have either a positive or a negative influence. The evidence is considered that heart-rate variability (HRV) (the time differences between one beat and the next) can be used to indicate the potential health benefits of food items. Reduced HRV is associated with the development of numerous conditions for example, diabetes, cardiovascular disease, inflammation, obesity and psychiatric disorders...

The modern lifestyle is characterised by various factors that cause accelerating ageing by the upregulation of oxidative stress and inflammation-two processes that are inextricably linked in an endless circle of self-propagation. Inflammation in particular is commonly accepted as aetiological factor in many chronic disease states, such as obesity, diabetes and depression. In terms of disease prevention or treatment, interventions aimed at changing dietary and/or exercise habits have had limited success in practise, mostly due to poor long-term compliance...

Cereal grains and grain pulses are primary staples often consumed together, and contribute a major portion of daily human calorie and protein intake globally. Protective effects of consuming whole grain cereals and grain pulses against various inflammation-related chronic diseases are well documented. However, potential benefits of combined intake of whole cereals and pulses beyond their complementary amino acid nutrition is rarely considered in literature. There is ample evidence that key bioactive components of whole grain cereals and pulses are structurally different and thus may be optimized to provide synergistic/complementary health benefits...

Inflammatory bowel disease (IBD) is a collection of inflammatory conditions of colon and small intestine which affect millions of individuals worldwide and the prevalence amount is on the rise. The organ failure as well as loss of tissue function is because of the inflammatory reaction which is the major contributor of tissue healing leading to lifelong debilitation. To stop the tough consequences of inflammation every patient pursues alternative therapy to relieve symptoms. Green tea polyphenols (GTPs) play significant roles in down regulating signaling pathways because GTPs exert effective antioxidant properties and regulate Toll-like receptor 4 (TLR4) expression via certain receptor, inhibited endotoxin-mediated tumor necrosis factor alpha (TNF-α) production by blocking transcription nuclear factor-kappa B (NF-kB) activation and upstream of mediated I kappa B kinase complex pathway activities, as well as intrusion with the flow of cytokines and synthesis of cyclooxygenase-2 (COX-2)...

Maternal malnutrition is known to increase the risk of obesity in offspring. We investigated whether green tea extract (GTE) intake during lactation affects obesity-related fibrosis and inflammation in the kidney of high-fat-diet-fed adult offspring of protein-restricted-diet-fed dams during pregnancy and lactation. Pregnant Wistar rats received diets containing 20% (normal-protein, NP) or 8% (low-protein, LP) casein, and they received 0%-, 0.12%- or 0.24%-GTE-containing LP diets (LP/LP, LP/LGT and LP/HGT, respectively) during lactation...

Anthocyanins are food compounds which belong to polyphenols and can mainly be found in dark fruits (e.g., blueberries, black currants, cranberries) and vegetables (e.g., red cabbage, radish, eggplant). The results of large research have shown that these compounds play an important role in the prevention of type 2 diabetes (T2D). In rodent studies and in studies with isolated omental adipocytes, it was observed that anthocyanins regulated the carbohydrate metabolism in the body due to the upregulation of GLUT4 (insulinregulated glucose transporter) translocation, increased activation of PPARγ (peroxisome proliferator-activated receptor-γ) in adipose tissue and skeletal muscles as well as increased secretion of adiponectin and leptin...

The link between obesity-induced systemic inflammation and decreased insulin signalling is well-known. It is also known that peripherally produced inflammatory cytokines can cross the blood-brain barrier, resulting in the release of neurotoxins that can ultimately lead to the demise of central nervous system integrity. A high-mesembrine Sceletium tortuosum extract was recently shown to possess cytoprotective and mild anti-inflammatory properties in monocytes and to target specific p450 enzymes to reduce adrenal glucocorticoid synthesis...

Flavonoids are allocated among various vegetations and in foodstuffs; consequently, they represent an inevitable part of the diet. Historical and epidemiological proof recommend that diet plans loaded with flavonoids such as quercetin have positive health benefits, especially on the heart. Flavonoids have been proven to have potential action towards hypertension, inflammation, diabetes and vascular disease. Their results on LDL lowering, platelet aggregation and vasodilatation recommend an ability to expel the pathophysiology of atherosclerotic plaque formation...

Fluorosis (fluoride toxicity) seems to be reduced by plant secondary metabolites. Tamarind seed coat extract (TSCE), a mixture of procyanidins and polyphenols, possesses numerous pharmacological activities. Regardless of its beneficial properties, the underlying molecular mechanism against chronic fluorosis in vivo is not known. Hence, the present study is aimed to investigate the efficacy of TSCE against fluoride (F- )-induced pulmonary toxicity in rats. Female Wistar rats were randomly divided into four groups and treated with NaF (300 ppm in drinking water) and TSCE (100 mg/kg/bw by oral intubation) alone and in combination daily for 30 days...

Cardiac fibrosis, in response to injury and stress, is central to a broad constellation of cardiovascular diseases. Fibrosis decreases myocardial wall compliance due to extracellular matrix (ECM) accumulation, leading to impaired systolic and diastolic function and causing arrhythmogenesis. Although some conventional drugs, such as β-blockers and renin-angiotensin-aldosterone system (RAAS) inhibitors, have been shown to alleviate cardiac fibrosis in clinical trials, these traditional therapies do not tend to target all the fibrosis-associated mechanisms, and do not hamper the progression of cardiac fibrosis in patients with heart failure...

SCOPE: Stress is a known contributor to various forms of disease in humans and animals, although mechanisms are still unknown. In animals, psychosocial stress-induced depression/anxiety phenotypes are coincidental with increased inflammation in both brain and blood. We recently showed that a novel treatment with a select bioactive polyphenol preparation promotes resilience to stress-mediated depression/anxiety phenotypes mice. Moreover, we identified selective bioactive phenolic compounds within the polyphenol preparation that were effective in mitigating the behavioral effects of bone marrow transplantation from stressed mice...
