Studies

In addition to vitamins B1, B6, C and K, grape also contains polyphenols that, with their antioxidant activity, perform various protective actions: increase in gene expression or antioxidant protein, attenuation of stress signaling of the endoplasmic reticulum, blockage of pro-inflammatory cytokines or endotoxin-mediated kinases and transcription factors involved in metabolic diseases, suppression of inflammation (1). These actions can reduce obesity-mediated chronic inflammation by multiple mechanisms, thus preventing metabolic diseases.

In addition, it seems established an effect of stimulation of memory in older people through an integration of grape juice that has produced a reduction in vascular disease in people with cardiovascular disease (2)

Piceatannol (trans-3,4,3',5'-tetrahydroxystilbene) , a polyphenol of grape, regulating the expression of proteins involved in the migration of cancer cells, would appear to be able to counteract their migration in the prostate (3).

Vitis rotundifolia extracts produced an anti-cancer action against a particularly aggressive tumour, triple-negative breast cancer. The positive action can be traced back to the antitumor and antioxidant activity carried out by the phenolic content and flavonoids present in this type of grape (4).

Resveratrol (3,5,4'-trans-trihydroxystilbene) is present in the skin and seeds of the grape. It is a polyphenolic component belonging to the stilbene family that protects plants from stress, infections and other diseases. Resveratrol has a wide range of biological properties with anti-inflammatory, neuroprotective, anticancer, anti-aging (5).

Abstract. Obesity and metabolic disease-related health problems (e.g., type 2 diabetes, atherosclerosis, and hypertension) are the most prevalent nutrition-related issues in the United States. An emerging feature of obesity and type 2 diabetes is their linkage with chronic inflammation that begins in white adipose tissue and eventually becomes systemic. One potential strategy to reduce inflammation and insulin resistance is consumption of polyphenol-rich foods like grapes or their by-products, which have anti-inflammatory properties. Polyphenols commonly found in grape products have been reported to reduce inflammation by (a) acting as an antioxidant or increasing antioxidant gene or protein expression, (b) attenuating endoplasmic reticulum stress signaling, (c) blocking proinflammatory cytokines or endotoxin-mediated kinases and transcription factors involved in metabolic disease, (d) suppressing inflammatory- or inducing metabolic-gene expression via increasing histone deacetylase activity, or (e) activating transcription factors that antagonize chronic inflammation. Thus, polyphenol-rich grape products may reduce obesity-mediated chronic inflammation by multiple mechanisms, thereby preventing metabolic diseases.

Abstract. Concord grape juice contains polyphenol compounds, which have antioxidant and anti-inflammatory properties and influence neuronal signalling. Concord grape juice supplementation has been shown to reduce inflammation, blood pressure and vascular pathology in individuals with CVD, and consumption of such flavonoid-containing foods is associated with a reduced risk for dementia. In addition, preliminary animal data have indicated improvement in memory and motor function with grape juice supplementation, suggesting potential for cognitive benefit in ageing humans. In this initial investigation of neurocognitive effects, we enrolled twelve older adults with memory decline but not dementia in a randomised, placebo-controlled, double-blind trial with Concord grape juice supplementation for 12 weeks. We observed significant improvement in a measure of verbal learning and non-significant enhancement of verbal and spatial recall. There was no appreciable effect of the intervention on depressive symptoms and no effect on weight or waist circumference. A small increase in fasting insulin was observed for those consuming grape juice. These preliminary findings suggest that supplementation with Concord grape juice may enhance cognitive function for older adults with early memory decline and establish a basis for more comprehensive investigations to evaluate potential benefit and assess mechanisms of action.

Abstract. Muscadine grape pomace and mixed products with chocolate extracts from three muscadine genotypes exhibiting different berry skin colors (black and bronze) were investigated for total phenolic content (TPC), total flavonoid content (TFC), DPPH, FRAP antioxidant activity, and anticancer activity using MDA-MB-468 (MM-468; African American) breast cancer cells. Muscadine berry extracts and mixed products showed cytotoxicity activities of up to 70% against MM-468 breast cancer cells. Cell growth inhibition was higher in 'macerated Floriana' with an IC50 value of 20.70 ± 2.43 followed by 'Alachua' with an IC50 value of 22.25 ± 2.47. TPC and TFC in macerated MGP powder were (1.4 ± 0.14 and 0.45 ± 0.01 GAE/g FW, respectively), which was significantly higher than those in cocoa powder. Data analysis showed a high association between DPPH, FRAP antioxidant activities, and TPC content and a positive high correlation between anticancer activity and antioxidant capacity and between TPC and anticancer activity. The anticancer and antioxidant effects of muscadine grape pomace and chocolate extracts are attributed to the TPC of extracts, which showed a stronger positive correlation with growth inhibition of African American breast cancer cells. This study would be of great value for food industries as well as other manufacturers who are interested in new food blends.

 Abstract. Resveratrol is a polyphenol that is abundant in grape skin and seeds. Food sources of resveratrol include wine, berries, and peanuts. This compound has many properties, including activity against glycation, oxidative stress, inflammation, neurodegeneration, several types of cancer, and aging. Because resveratrol is generally welltolerated, it is believed to be a promising compound in preventing many diseases, such as diabetes and its complications. Unfortunately, this compound exhibits low bioavailability and solubility. The aim of this review is to summarize the latest information on the multiple effects of resveratrol on health and the benefits of its intake, based on in vitro and in vivo studies in animals and humans.

  Abstract. Resveratrol is a phytoalexin polyphenolic compound found in various plants, including grapes, berries, and peanuts. Multiple lines of compelling evidence indicate its beneficial effects on neurological, hepatic, and cardiovascular systems. Also one of the most striking biological activities of resveratrol soundly investigated during the late years has been its cancer-chemopreventive potential. In fact, recently it has been demonstrated that this stilbene blocks the multistep process of carcinogenesis at various stages: tumor initiation, promotion, and progression. One of the possible mechanisms for its biological activities involves downregulation of the inflammatory response through inhibition of synthesis and release of pro-inflammatory mediators, modification of eicosanoid synthesis, inhibition of activated immune cells, or inhibiting such as inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) via its inhibitory effects on nuclear factor (kappa)B (NF-(kappa)B) or the activator protein-1 (AP-1). More recent data provide interesting insights into the effect of this compound on the lifespan of yeast and flies, implicating the potential of resveratrol as an anti-aging agent in treating age-related human diseases. It is worthy to note that the phenolic compound possesses a low bioavailability and rapid clearance from the plasma. As the positive effects of resveratrol on inflammatory response regulation may comprise relevant clinical implications, the purpose of this article is to review its strong anti-inflammatory activity and the plausible mechanisms of these effects. Also, this review is intended to provide the reader an up-date of the bioavailability and pharmacokinetics of resveratrol and its impact on lifespan.
