Abstracts from this week's Doctor's Guide Nutrition/Dietetics plus abstracts from my RSS feeds (Click here for the journals, the PubMed ones at the top):

Effect of omega-3 and policosanol supplementation on attention and reactivity in athletes - J Am Coll Nutr. 2009 Aug;28 - "After 21 days of supplementation, subjects who received O3 + P showed a reduced reaction time and increased vigor sensation associated with a reduction of the negative states measured with the POMS test. Analysis of the event-related brain potentials showed a reduced latency of the movement-related brain macropotentials. In particular, the potentials recorded in the premotor period and motor period occurred earlier and the latency of EMG activation was reduced. In the third test, 21 days after the last O3 + P supplementation, the positive effects on the mood state persisted, while the reaction time, EMG, and brain potential latencies increased, although their values remained lower than in the first test. The placebo group did not show any significant differences in Tests 2 and 3 compared to Test 1 for either POMS or reactivity and brain potentials"

Coffee Consumption and Mortality Due to All Causes, Cardiovascular Disease, and Cancer in Japanese Women - J Nutr. 2010 Mar 24 - "In women, the multivariate hazard ratios (HR) (95% CI) for all-cause mortality in participants who drank coffee never, occasionally, 1-2 cups (150-300 mL)/d, and >/=3 cups/d were 1.00, 0.88 (0.73-1.06), 0.82 (0.66-1.02), and 0.75 (0.53-1.05), respectively (P-trend = 0.04). For CVD mortality in women, the multivariate HR (95% CI) were 1.00, 0.56 (0.36-0.86), 0.48 (0.29-0.80), and 0.45 (0.20-1.03), respectively (P-trend = 0.006). Of the specific CVD diseases, there was a strong inverse association between coffee consumption and mortality due to coronary heart disease (CHD) in women (P-trend = 0.02) but not in men. Death due to cancer was not associated with coffee consumption in either men or women, except for colorectal cancer in women. Our results suggest that coffee may have favorable effects on morality due to all causes and to CVD, especially CHD, in women"

Marine (n-3) Fatty Acids, Fish Consumption, and the 10-Year Risk of Fatal and Nonfatal Coronary Heart Disease in a Large Population of Dutch Adults with a Low Fish Intake - J Nutr. 2010 Mar 24 - "Compared with the lowest quartile of EPA+DHA, participants in the top quartile had a 49% lower risk of fatal CHD (95% CI: 6-73%) and a 62% lower risk of fatal MI (95% CI: 23-81%). We observed inverse dose-response relations for EPA+DHA intake and fatal CHD (P-trend = 0.05) and fatal MI (P-trend = 0.01)" - See Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com.

Dietary vitamin K intake in relation to cancer incidence and mortality: results from the Heidelberg cohort of the European Prospective Investigation into Cancer and Nutrition (EPIC-Heidelberg) - Am J Clin Nutr. 2010 Mar 24 - "Dietary intake of menaquinones was nonsignificantly inversely associated with overall cancer incidence (HR for the highest compared with the lowest quartile: 0.86; 95% CI: 0.73, 1.01; P for trend = 0.08), and the association was stronger for cancer mortality (HR: 0.72; 95% CI: 0.53, 0.98; P for trend = 0.03). Cancer risk reduction with increasing intake of menaquinones was more pronounced in men than in women, mainly driven by significant inverse associations with prostate (P for trend = 0.03) and lung cancer (P for trend = 0.002). We found no association with phylloquinone intake" - See vitamin K at Amazon.com.

News & Research:

  • Grape Seed Extract - The Natural Pharmacist
  • Grape Seed - Compiled by Chad Bradshaw, Pharm.D
  • Pine bark extract may benefit blood pressure-related kidney health - Nutra USA, 3/5/10 - "55 hypertensive patients to participate in the randomized, controlled study. Subjects were assigned to receive Ramipril [an ACE inhibitor] (10 mg per day), and 29 of these people were randomly selected to also receive Pycnogenol (150 mg per day) ... After six months in the Ramipril-only group the albumin levels decreased by 26 per cent to 64 mg per 24-hour period, while additional Pycnogenol produced levels that averaged 39 mg per 24-hour period, equivalent to a 57 per cent decrease ... Statistically significant decreases in patients’ blood pressure were also observed, with systolic and diastolic blood pressures dropping by more than 30 and 8 per cent, respectively in the Ramipril-only group, and by a further 3 to 6 per cent in the combination group ... Diastolic and systolic blood flow improved by 8 and 12 per cent, in the combination group" - [Abstract]
  • OPCs come out tops for heart health beverages - Nutra USA, 2/5/10 - "Cranberry juice rich in antioxidant procyanidins is effective at boosting the health of blood vessels ... oligomeric procyanidins (OPC) had “by far the most potent effects” on the function of the endothelium (the cells lining blood vessels)" - [Abstract] - See cranberry extract at Amazon.comand grape seed extract at Amazon.com.
  • Pine bark extract may boost diabetic eye health - Nutra USA, 12/3/09 - "At the end of the study, 75 per cent of participants in the Pycnogenol group subjectively perceived improvements in their visual acuity. Tests showed a significant improvement in visual acuity from 14/20 to 17/20 after two months of Pycnogenol supplementations. No improvements were recorded in the placebo group" -  [Abstract]
  • Antioxidant OPCs may boost memory: Animal study - Nutra USA, 10/16/09 - "The results showed that OPC-consuming animals had “improved spatial and object recognition impairment”" - [Abstract] - See grape seed extract at Amazon.com.
  • How To Boost Value Of Alzheimer's-fighting Compounds - Science Daily, 9/7/09 - "Connie Weaver, Purdue's head of foods and nutrition; and Elsa Janle, a Purdue associate professor of foods and nutrition, found that the amount of polyphenols from grapeseed extract that can reach a rat's brain is as much as 200 percent higher on the 10th consecutive day of feeding as compared to the first. Many previous experiments, in which absorption was measured after single or sporadic doses, often found very little, if any, of the bioactive polyphenols reaching brain tissues. However, more chronic exposure appears to improve absorption ... This shows that reasonable and chronic consumption of these products may be the way to go, rather than single, high doses"
  • Chemicals Found In Fruit And Vegetables Offer Dementia Hope - Science Daily, 7/19/09 - "a new concept is emerging that suggests flavonoids do not act simply as antioxidants but exert their biological effects through other mechanisms. A small number of recent studies carried out in models of Alzheimer’s disease have found that oral administration of green tea flavonoids or grape flavonoids reduces brain pathology and, in some cases, improves cognition. Dr Williams and colleagues have focused their own cellular studies on a flavonoid called epicatechin, which is abundant in a number of foodstuffs, including cocoa ... epicatechin protects brain cells from damage but through a mechanism unrelated to its antioxidant activity and shown in laboratory tests that it can also reduce some aspects of Alzheimer’s disease pathology" - See grape seed extract at Amazon.com
  • Benefit Of Grapes May Be More Than Skin Deep: Lower Blood Pressure, Reduced Heart Damage - Science Daily, 4/22/09 - "After 18 weeks, the rats that received the grape-enriched diet powder had lower blood pressure, better heart function, and fewer signs of heart muscle damage than the rats that ate the same salty diet but didn't receive grapes ... Rats that received the blood pressure medicine, hydrazine, along with a salty diet also had lower blood pressure, but their hearts were not protected from damage as they were in the grape-fed group"
  • Grape polyphenols may protect against obesity: Study - Nutra USA, 3/18/09 - "animals fed a high-fat diet but supplemented with the grape seed extract had adiponectin levels 61 per cent higher than animals only fed the high fat diet. Adiponectin is a protein hormone linked to various metabolic processes, and levels are inversely related to body fat levels" - [Abstract] - See grape seed extract at Amazon.com.
  • Grape Extracts May Be Effective Against Harmful Gut Bacteria - Science Daily, 3/4/09 - "H. pylori is the bacterial agent most commonly associated with peptic ulcers, gastritis, mucosa-associated lymphoid tissue lymphoma, and gastric cancer ... The antibacterial effects of extracts from red, white, black and muscadine grapes as well as the pure compounds resveratrol, ellagic acid, and myricetin were tested for anti-H. pylori activity using agar dilution, laser scanning microscopy and cell proliferation. Following 24 hour treatment, results showed that muscadine grape skin extract had the highest anti-H. pylori effect, followed by muscadine grape synergy and seed extract. Additionally, two of the three compounds, resveratrol and ellagic acid, also inhibited H. pylori" - See grape seed extract at Amazon.com and resveratrol at Amazon.com.
  • Grape-seed Extract Kills Laboratory Leukemia Cells, Proving Value Of Natural Compounds - Science Daily, 12/31/08 - "An extract from grape seeds forces laboratory leukemia cells to commit cell suicide, according to researchers from the University of Kentucky.

They also discovered that the extract does not affect normal cells, although they don't know why"
  • Anthocyanins battle blood vessel degradation: study - Nutra USA, 12/22/08 - "OPC was found to effectively delay SIPS (stress induced senescence) caused by exposure to rotenone, a chemical substance that is known to generate oxidative stress ... The ability of OPCs to delay senescence was associated with a decrease in the levels of a marker of DNA damage and DNA terminal ends (gamma-H2AX), suggesting that the possible molecular mechanism by which OPCs delay senescence in endothelial cells is through reduction in DNA damage" - See grape seed extract at Amazon.com.  I've been taking 50 mg three times per day for years.
  • Pine bark extract may help joints and hearts: Study - Nutra USA, 12/11/08 - "The decrease of systemic inflammatory markers, particularly CRP, suggests Pycnogenol properties may be potent enough to arrest the spread of inflammation from osteoarthritic joints to the whole organisms ... subjects received either two daily doses of 50 mg Pycnogenol or placebo for three months ... people receiving the pine bark extract experienced significant reductions in CRP levels from an average of 3.9 mg/L at the start of the study to 1.1 mg/L after three months. This is equivalent to a 71 per cent reduction ... Moreover, a reduction in the blood levels of reactive oxygen species (ROS) of 30 per cent was recorded" - See Pycnogenol at Amazon.com.
  • Grape seed extract may boost oral health: Study - Nutra USA, 11/26/08 - "The extracts showed a good antibacterial activity, as evidence by the minimum inhibitory concentrations (MIC) of the test compound against the two strains"
  • How Red Wine Compounds Fight Alzheimer's Disease - Science Daily, 11/23/08 - "Teplow's lab has been studying how amyloid beta (Aß) is involved in causing Alzheimer's. In this work, researchers monitored how Aß40 and Aß42 proteins folded up and stuck to each other to produce aggregates that killed nerve cells in mice. They then treated the proteins with a polyphenol compound extracted from grape seeds. They discovered that polyphenols carried a one-two punch: They blocked the formation of the toxic aggregates of Aß and also decreased toxicity when they were combined with Aß before it was added to brain cells"
  • Grapes May Aid A Bunch Of Heart Risk Factors, Animal Study Finds - Science Daily, 10/29/08 - "Could eating grapes help fight high blood pressure related to a salty diet? And could grapes calm other factors that are also related to heart diseases such as heart failure? A new University of Michigan Cardiovascular Center study suggests so"
  • Grapes And Grape Extracts May Lower Cardiovascular Disease Risk, Review Article Suggests - Science Daily, 10/28/08 - "grape polyphenols work in many different ways to prevent cardiovascular and other "inflammatory-mediated" diseases. Polyphenols are natural antioxidants found in grapes and some other plant foods. Their types and actions vary, depending on where in the grape they are found. Grape seeds, grape skin, and grape juice contain several types of polyphenols, including resveratrol, phenolic acids, anthocyanins, and flavonoids" - See grape seed extract at Amazon.com.

In addition to a reduction in the use of NSAIDs, a reduction in the number of painful days due to dysmenorrhea from 2.1 days before supplementation to 1.3 days during the third and fourth menstrual cycle" - See Pycnogenol at Amazon.com or grape seed extract at Amazon.com (some say the grape seed extract is the same without the patent markup).
  • Grape Seed Extract May Reduce Cognitive Decline Associated With Alzheimer's Disease - Science Daily, 6/17/08 - "Chemical analysis showed that the major polyphenol components in the study's grape seed extract product are catechin and epicatechin, which are also abundant in tea and cocoa. These components differ from resveratrol, a polyphenol that has been reported to reduce amyloid beta secretion in cells and generally increase lifespan by mimicking calorie restriction. Resveratrol appears to be effective only at extremely high doses, which may limit its use in people. In contrast, the catechins in the extract product studied appear to be effective at much lower doses" - [Nutra USA] - My favorite is the grape seed extract at Amazon.com.
  • Pine bark extract may boost diabetics' heart health - Nutra USA, 5/12/08 - "recruited diabetic subjects with an average age of 60 and randomly assigned them to receive daily supplements of Pycnogenol (125 mg) or placebo for 12 weeks ...

  • Red Wine And Grape Juice Help Defend Against Food-borne Diseases, Study Suggests - Science Daily, 10/11/07
  • Proanthocyanidin from grape seeds inactivates the PI3-kinase/PKB pathway and induces apoptosis in a colon cancer cell line - Cancer Lett. 2007 Oct 6 - "grape seed proanthocyanidin extract (GSPE) ... GSPE (10-100mug/ml) significantly inhibited cell viability and increased apoptosis in CaCo2 cells, but did not alter viability in the normal colon cell line (NCM460). The increased apoptosis observed in GSPE-treated CaCo2 cells correlated with an attenuation of PI3-kinase (p110 and p85 subunits) and decreased PKB Ser(473) phosphorylation. GSPE might thus exert its beneficial effects by means of increased apoptosis and suppression of the important PI3-kinase survival-related pathway"

Abstracts:

  • Kidney flow and function in hypertension: protective effects of pycnogenol in hypertensive participants--a controlled study - J Cardiovasc Pharmacol Ther. 2010 Mar;15(1):41-6 - "evaluated the effects of Pycnogenol as an adjunct to angiotensin-converting enzyme (ACE)-inhibitor ramipril treatment of hypertensive patients presenting with early signs of renal function problems. One group of 26 patients was medicated with 10 mg ramipril per day only; a second group of 29 patients took Pycnogenol in addition to the ACE inhibitor over a period of 6 months ... Urinary albumin decreased from 87 +/- 23 to 64 +/- 16 mg/d with ramipril only. Additional Pycnogenol lowered albumin significantly better from 91 +/- 25 to 39 +/- 13 mg/day (P < .05). In both groups, serum creatinine was lowered; however, only in the combination treatment group did the effect reached statistical significance. In both groups, CRP levels decreased from 2.1 to 1.8 with ramipril and from 2.2 to 1.1 with the ramipril-Pycnogenol combination; the latter reached statistical significance. Kidney cortical flow velocity was investigated by Doppler color duplex ultrasonography. Both systolic and diastolic flow velocities increased significantly after 6 months medication with ramipril. The addition of Pycnogenol to the regimen statistically significantly further enhanced kidney cortical flow velocities, by 8% for diastolic flow and 12% for systolic flow, relative to values found for the group taking ramipril only"
  • Regulation of Vascular Endothelial Function by Procyanidin-Rich Foods and Beverages (dagger) - J Agric Food Chem. 2010 Jan 28 - "Evaluation of the relative effects of extracts of cranberry juice compared to apple, cocoa, red wine, and green tea showed inhibition of ET-1 synthesis was dependent primarily on their oligomeric procyanidin content. Procyanidin-rich extracts of cranberry juice triggered morphological changes in endothelial cells with reorganization of the actin cytoskeleton and increased immunostaining for phosphotyrosine residues ... procyanidin tetramer, pentamer, hexamer, and heptamer produced concentration-dependent decreases with IC(50) values of 5.4, 1.6, 0.9, and 0.7 muM, respectively. Levels of ET-1 mRNA showed a similar pattern of decreases, which were inversely correlated with increased expression of Kruppel-like factor 2 (KLF2), a key endothelial transcription factor with a broad range of antiatherosclerotic actions including suppression of ET-1 synthesis" - See cranberry extract at Amazon.comand grape seed extract at Amazon.com.

  • Oligomeric proanthocyanidins improve memory and enhance phosphorylation of vascular endothelial growth factor receptor-2 in senescence-accelerated mouse prone/8 - Br J Nutr. 2009 Oct 13:1-11 - "This indicates that oligomers result in an increase in the densities of axons, dendrites and synapses. To investigate the protective mechanisms of oligomers against brain dysfunction with ageing, we carried out a receptor tyrosine kinase phosphorylation antibody array, and clarified that the administration of oligomers led to an increase in the phosphorylation of vascular endothelial growth factor receptor (VEGFR)-2, suggesting the neuroprotective role of oligomers. The phosphorylation of VEGFR-2 was more greatly increased in the hypothalamus and choroid plexus than in other brain regions of SAMP8. Memory in oligomer-treated mice was impaired by SU1498, a VEGFR-2-specific antagonist. Elucidating the relationship between memory impairment with ageing and VEGFR-2 signalling may provide new suggestions for protection against memory deficit in the ageing brain" - See grape seed extract at Amazon.com.

Similar associations were not seen in never smokers. Isoflavone intake was inversely associated with overall cancer incidence (HR = 0.93, 95% CI: 0.86-1.00). This study provides further support for a beneficial effect of flavonoid intake on lung cancer risk, especially among current and past smokers"
  • Multi-targeted prevention and therapy of cancer by proanthocyanidins - Cancer Lett. 2008 May 3 - "A wide variety of botanicals, mostly dietary flavonoids or polyphenolic substances, have been reported to possess substantial anti-carcinogenic and antimutagenic activities because of their antioxidant and anti-inflammatory properties. Proanthocyanidins are considered as one of them, and are abundantly available in various parts of the plants, such as fruits, berries, bark and seeds. Their modes of action were evaluated through a number of in vitro and in vivo studies which showed their potential role as anti-carcinogenic agent. We summarize and highlight the latest developments on anti-carcinogenic activities of proanthocyanidins from different sources, specifically from grape seeds, and their molecular targets, such as NF-kappaB, mitogen-activated protein kinases, PI3K/Akt, caspases, cytokines, angiogenesis and cell cycle regulatory proteins and other check points, etc. Although the bioavailability and metabolism data on proanthocyanidins is still largely unavailable, certain reports indicate that at least monomers and smaller oligomeric procyanidins are absorbed in the gut. The modulation of various molecular targets by proanthocyanidins in vitro and in vivo tumor models suggests their importance, contribution and mechanism of action to the prevention of cancers of different organs" - See grape seed extract at Amazon.com and Pycnogenol at Amazon.comSome say the grape seed extract if the same as Pycnogenol without the patent markup.
