Recent Longevity News for the seven days ending 3/23/11.  You should consult your doctor if you are taking any medications.

A Molecular Link Between Sleep and Liver Fat - nih.gov, 3/21/11 - "As many as 1 in 4 Americans are estimated to have excess liver fat, which can lead to inflammation and damage that could eventually cause liver failure. Fat production in the liver is known to be affected by circadian rhythms. Past studies have shown that disrupting circadian rhythms in mice causes the animals to develop excess liver fat. They also suffer from obesity, diabetes and metabolic syndrome ... during the day, when mice are asleep and fasting, HDAC3 and rev-erbα help prevent the liver from producing fat. As predicted, when either protein was removed from the mouse liver, the fat metabolism genes became active regardless of time or activity level. This led to a rapid buildup of fat in the liver ... This may explain in part why altered circadian rhythms in people who do shift work is associated with metabolic disorders"

Oral Tongue Cancer Rates Rising in Young White Women - Medscape, 3/21/11 - "among people 18 to 44 years of age, the incidence of oral tongue cancer climbed 28% between 1975 and 2007. Among white people in this age group, the incidence increased 67%. The rising rates were most dramatic for white women, with a jump of 111% ... These trends, note the authors, might be explained by the decreased use of tobacco and the association between the carcinogenic strains of human papillomavirus (HPV) and cancer of the oral cavity ... I would say that if a young white person has complaints of a persistent sore on their tongue, cancer should be moved up higher on the differential, based on our study ... I would say that if a young white person has complaints of a persistent sore on their tongue, cancer should be moved up higher on the differential, based on our study"

A dose of safflower oil each day might help keep heart disease at bay - Science Daily, 3/21/11 - "safflower oil reduced abdominal fat and increased muscle tissue in this group of women after 16 weeks of daily supplementation ... Safflower oil contains linoleic acid, which is a PUFA -- a polyunsaturated fatty acid ... For this current research, the scientists performed a secondary analysis of data collected from that clinical trial, applying a powerful statistical analysis to the results and also checking to see how long it took for any effects of the oils to appear in the women's health profiles" - Note:  It was in the news so I included it but I'm not buying it.  American's already get about 10 to 20 times too much omega-6.  So using their theory they should already be healthy.  As far as it raising HDL, the Atkin's diet also raised HDL, it doesn't necessarily mean it's a good way to accomplish it.

Time lived with obesity linked with mortality - Science Daily, 3/21/11 - "for those who had a medium number of years lived with obesity (between five years and 14.9 years), the risk of mortality more than doubled than for those who had never been obese. The risk of mortality almost tripled for those with the longest duration of obesity (more than 15 years)"

Pterostilbene ‘more potent than resveratrol’ for colon health: Study - Nutra USA, 3/21/11 - "the chemopreventive effect of pterostilbene was more potent than resveratrol and was associated with a decreased inflammation as well as modulation of the antioxidant signaling pathways in the colons of mice" - [Abstract] - See pterostilbene at Amazon.com.

Mouth Rinse Effective in Reducing Risk for Preterm Birth - Medscape, 3/18/11 - "An over-the-counter mouthwash reduced the risk for preterm birth by more than two thirds in women with periodontal disease ... Only 6.1% of the women using the rinse experienced preterm births, which the researchers defined as birth at less than 35 weeks. In comparison, 21.9% of the untreated group experienced preterm births" - Note: It makes you wonder if the bacteria in your mouth my me just as harmful with increasing diabetes and heart disease.

Vitamin A plays key role in the human body, study suggests - Science Daily, 3/17/11 - "Our study found that Vitamin A itself is active for activating nuclear receptor TR4 ... Because TR4 plays roles in sperm cell production, lipid and lipoprotein regulation, the development of the central nervous system, and the regulation of hemoglobin production in the embryo, we can imagine that Vitamin A may play more important roles in human physiology than was previously believed"

U.S. Death Rate Hits Record Low - WebMD, 3/16/11 - "The 15 leading causes of death in 2009 and the decreases in associated death rates were reported as follows: ... 1.Heart disease: 3.7% ... 2.Cancer: 1.1% ... 3.Chronic lower respiratory diseases: 4.1% ... 4.Stroke: 4.2% ... 5.Accidents: 4.1% ..."

Does selenium prevent cancer? It may depend on which form people take - Science Daily, 3/16/11 - "Hugh Harris and colleagues note that although the Nutritional Prevention of Cancer clinical trial showed that selenium reduced the risk of cancer, a later study called the Selenium and Vitamin E Cancer Prevention Trial did not show a benefit. A major difference between the trials was the form of selenium that was used. To find out whether different types of selenium have different chemopreventive properties, the researchers studied how two forms -- SeMet and MeSeCys -- are processed in human lung cancer cells ... The researchers found that MeSeCys killed more lung cancer cells than SeMet did. Also, lung cancer cells treated with MeSeCys processed the selenium differently than than cells treated with SeMet"

Selenium deficiency may increase risk of chronic disease: Study - Nutra USA, 3/16/11 - "Since the current [US] RDA (55 micrograms per day, roughly corresponding to 100 micrograms per liter of plasma selenium) is based on the sensitivity of Gpx3 in plasma, Sepp1 is expected to be at suboptimal levels, even in some individuals meeting current selenium intake recommendations ... Based on these findings, it recently was suggested that recommended selenium intake levels should be raised from 55 to 75 micrograms per day ... cancer prevention remains one of the major benefits of selenium, and it is the only mineral that qualifies for a Food and Drug Administration (FDA)-approved qualified health claim for general cancer reduction incidence" - [Abstract] - See selenium at Amazon.com.

Antibiotics May Make Fighting Flu Harder - Science News, 3/14/11 - "Iwasaki and her colleagues treated mice for a month with four antibiotics commonly given to people with bacterial infections, then infected the rodents with the flu. Antibiotic treatment impaired the mice’s ability to make an important flu-fighting molecule called interleukin-1 beta or IL-1 beta, the researchers found. IL-1 beta is necessary to combat influenza and other viruses ... Gut bacteria are constantly priming the immune system to make IL-1 beta, keeping the immune system vigilant against the flu and other viruses ... Some Lactobacillus bacteria, on the other hand, are known as “friendly” gut bacteria and may play a role in virus defense. Mice treated with an antibiotic called neomycin, which wipes out most types of Lactobacillus bacteria while leaving Sphingomonas bacteria alone, have a hard time fighting the flu" - Note:  It seems to be a common misconception of nearly everyone I know that if you've got a bad case of the flu you need to go to a doctor and get antibiotics when in reality, it probably slows recovery.

Pterostilbene ‘more potent than resveratrol’ for colon health: Study - J Agric Food Chem. 2011 Mar 23;59(6):2725-33 - "Inflammatory bowel diseases have been a risk factor of colorectal cancer (CRC). The reactive oxygen species (ROS) generated by inflammatory cells create oxidative stress and contribute to neoplastic transformation, proliferation, and even metastasis. Previously, resveratrol (RS) and pterostilbene (PS) had been reported to prevent chemical-induced colon carcinogenesis by anti-inflammatory and pro-apoptotic properties ... Administrations of PS can be more effective than RS in reducing AOM-induced formation of aberrant crypt foci (ACF), lymphoid nodules (LNs), and tumors. We also find that PS is functioning more effectively than RS to reduce nuclear factor-κB (NF-κB) activation by inhibiting the phosphorylation of protein kinase C-β2 (PKC-β2) and decreasing downstream target gene expression, including inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), and aldose reductase (AR) in mouse colon stimulated by AOM. Moreover, administration of RS and PS for 6 weeks significantly enhanced expression of antioxidant enzymes, such as heme oxygenase-1 (HO-1) and glutathione reductase (GR), via activation of NF-E2-related factor 2 (Nrf2) signaling. When the above findings are taken together, they suggest that both stilbenes block cellular inflammation and oxidative stress through induction of HO-1 and GR, thereby preventing AOM-induced colon carcinogenesis. In comparison, PS was a more potent chemopreventive agent than RS for the prevention of colon cancer. This is also the first study to demonstrate that PS is a Nrf2 inducer and AR inhibitor in the AOM-treated colon carcinogenesis model" - See pterostilbene at Amazon.com.

Telmisartan Provides Better Renal Protection Than Valsartan in a Rat Model of Metabolic Syndrome - Am J Hypertens. 2011 Mar 17 - "spontaneously hypertensive rats (SHR) ... SHR were fed either normal (SHR-NF, 7% fat) or high fat (SHR-HF, 36% fat) diet and treated with an ARB for 10 weeks.ResultsBlood pressure was similar between SHR-NF (190 +/- 3 mm Hg) and SHR-HF (192 +/- 4 mm Hg) at the end of the 10 week period. Temisartan and valsartan decreased blood pressure to similar extents in SHR-NF and SHR-HF groups. Body weight was significantly higher in SHR-HF (368 +/- 5 g) compared to SHR-NF (328 +/- 7 g). Telmisartan but not valsartan significantly reduced the body weight gain in SHR-HF. Telmisartan was also more effective than valsartan in improving glycemic and lipid status in SHR-HF. Monocyte chemoattractant protein-1 (MCP-1), an inflammatory marker, was higher in SHR-HF (24 +/- 2 ng/d) compared to SHR-NF (14 +/- 5 ng/d). Telmisartan reduced MCP-1 excretion in both SHR-HF and SHR-NF to a greater extent than valsartan. An indicator of renal injury, urinary albumin excretion increased to 85 +/- 8 mg/d in SHR-HF compared to 54 +/- 9 mg/d in SHR-NF. Telmisartan (23 +/- 5 mg/d) was more effective than valsartan (45 +/- 3 mg/d) in lowering urinary albumin excretion in SHR-HF. Moreover, telmisartan reduced glomerular damage to a greater extent than valsartan in the SHR-HF.ConclusionsCollectively, our data demonstrate that telmisartan was more effective than valsartan in reducing body weight gain, renal inflammation, and renal injury in a rat model of cardiometabolic syndrome"

Curcumin attenuates lipopolysaccharide-induced renal inflammation - Biol Pharm Bull. 2011;34(2):226-32 - "Renal inflammation is the main pathological change in many acute and chronic kidney diseases. Curcumin, a yellow pigment present in the rhizome of turmeric (Curcuma longa L. Zingiberaceae), was found to be a potential anti-inflammatory agent ... The results demonstrated that curcumin could inhibit LPS-induced renal MCP-1 mRNA expression. Curcumin also significantly inhibited the expression of MCP-1 and IL-2 mRNA in HK-2 cells, and partially inhibited the secretion of MCP-1 and IL-8. Furthermore, curcumin was found to inhibit the DNA-binding activity of NF-κB. The present study demonstrated that curcumin has a protective effect on LPS-induced experimental renal inflammation, and this effect might be attributed to its inhibitory effects on MCP-1 mRNA expression and DNA-binding activity of NF-κB. Hence, curcumin might be potentially useful in some kidney diseases by preventing renal inflammation" - See curcumin products at Amazon.com.

Thiazolidenediones induce tumour-cell apoptosis through the Akt-GSK3β pathway - J Clin Pharm Ther. 2011 Mar 16 - "Prostate cancer is a major health threat for men. Thiazolidenediones (TZDs) are synthetic ligands of the peroxisome proliferator-activated receptor γ (PPARγ), and previous studies have shown that TZDs induce apoptosis of prostate cancer cells independently of PPARγ activation. However, the exact mechanism of these effects remains unknown ... The apoptosis-inducing effect of TZDs on prostate cancer cells involves the inhibition of Akt phosphorylation. Furthermore, TZDs induce inactivation of GSK3β, a multifunctional kinase that mediates essential events promoting prostate cancer development and acquisition of androgen independence. In addition, the GSK3β inhibitor lithium chloride sensitizes prostate cancer cells to TZDs cytotoxicity. What is new and Conclusion:  Our data suggest that modulation of Akt-GSK3β pathway is involved in the cell death pathway engaged by TZDs in prostate cancer cells. This reveals another possible mechanism of TZDs on apoptosis in prostate cancer. Inhibition of the Akt-GSK3β cascade may be a useful approach in prostate cancer" - Got that because I'm going to give a test on it in next weeks newsletter.  The point is that TZDs such as pioglitazone may help prevent or slow prostate cancer.  See Pioglitazone at OffshoreRx1.com.  This was in last weeks newsletter:

  • Pioglitazone activates aortic telomerase and prevents stress-induced endothelial apoptosis - Atherosclerosis. 2011 Feb 17 - "Telomeres and associated proteins are regulators of cellular survival, regeneration and aging. PPAR-γ agonists may mediate vascular effects in addition to insulin sensitizing. We therefore examined whether pioglitazone regulates vascular telomere biology ... C57/Bl6 mice were randomized to treatment with pioglitazone (20mg/kg i.p. daily) or vehicle for 4 weeks (n=6-8 per group). Telomere repeat amplification protocols showed a 2-fold increase of aortic telomerase activity in the pioglitazone group. Telomere repeat-binding factor 2 protein and mRNA levels (236%+172% of vehicle) as well as phosphorylation of protein kinase Akt (479% of vehicle) were up-regulated. Western blots demonstrated reduced aortic expression of senescence markers p16, cell-cycle checkpoint kinase 2 and p53. These regulatory mechanisms were independent of acute changes of telomere length. Similar observations were made in mononuclear cells (MNC) from these mice and in cultivated bovine aortic endothelial cells, human MNC and endothelial progenitor cells (EPC). Telomerase activation by pioglitazone in cultivated cells was prevented by Akt inhibitors. To test the functional relevance of the findings, isolated mononuclear cells (MNC) were exposed to H(2)O(2). MNC from pioglitazone-treated mice exhibited reduced apoptosis (AnnexinV-FACS). In vivo, lipopolysaccharide-induced aortic endothelial apoptosis was potently prevented in pioglitazone-treated animals (hairpin oligonucleotide assay). Both, up-regulation of telomere-regulating proteins and prevention of oxidative stress-induced aortic apoptosis, were absent in telomerase reverse transcriptase (TERT)-deficient mice ... The findings underscore the important role of telomere-regulating proteins for vascular cell function and survival" - Note:  My doctor says I'm crazy but I've been taking pioglitazone for anti-aging for years.  See pioglitazone at OffshoreRx1.com.

Sleep duration is significantly associated with carotid artery atherosclerosis incidence in a Japanese population - Atherosclerosis. 2011 Feb 24 - "Sleep duration ≥7h correlated significantly with the incidence of IMT≥1.2mm when compared with a sleep duration of 6h (multivariate-adjusted odds ratio, 1.263; 95% confidence interval, 1.031-1.546, P=0.024). Shorter sleep duration ≤5h did not correlate significantly with the risk compared with a sleep duration of 6h"

Consumption of polyunsaturated fatty acids, fish, and nuts and risk of inflammatory disease mortality - Am J Clin Nutr. 2011 Mar 16 - "Women in the highest tertiles of total n-3 PUFA intake, compared with those in the lowest tertile of intake at baseline, had a 44% reduced risk of inflammatory disease mortality (P for trend = 0.03). This association was not observed in men" - See Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com.

A Dietary Mixture Containing Fish Oil, Resveratrol, Lycopene, Catechins, and Vitamins E and C Reduces Atherosclerosis in Transgenic Mice - J Nutr. 2011 Mar 16 - "Chronic inflammation and proatherogenic lipids are important risk factors of cardiovascular disease (CVD). Specific dietary constituents such as polyphenols and fish oils may improve cardiovascular risk factors and may have a beneficial effect on disease outcomes ... AIDM was evaluated in an inflammation model, male human C-reactive protein (CRP) transgenic mice, and an atherosclerosis model, female ApoE*3Leiden transgenic mice. Two groups of male human-CRP transgenic mice were fed AIDM [0.567% (wt:wt) powder and 0.933% (wt:wt oil)] or placebo for 6 wk. The effects of AIDM on basal and IL-1β-stimulated CRP expression were investigated. AIDM reduced cytokine-induced human CRP and fibrinogen expression in human-CRP transgenic mice. In the atherosclerosis study, 2 groups of female ApoE*3Leiden transgenic mice were fed an atherogenic diet supplemented with AIDM [0.567% (wt:wt) powder and 0.933% (wt:wt oil)] or placebo for 16 wk. AIDM strongly reduced plasma cholesterol, TG, and serum amyloid A concentrations compared with placebo. Importantly, long-term treatment of ApoE*3Leiden mice with AIDM markedly reduced the development of atherosclerosis by 96% compared with placebo. The effect on atherosclerosis was paralleled by a reduced expression of the vascular inflammation markers and adhesion molecules inter-cellular adhesion molecule-1 and E-selectin. Dietary supplementation of AIDM improves lipid and inflammatory risk factors of CVD and strongly reduces atherosclerotic lesion development in female transgenic mice" - See resveratrol products at Amazon.com, Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com, Jarrow Formulas, CarotenALL at Amazon.com, green tea extract at Amazon.com and Jarrow FamilE (contains all eight members of the vitamin E family, includes Tocomin) at Amazon.com.

Carbohydrate Ingestion during Endurance Exercise Improves Performance in Adults - J Nutr. 2011 Mar 16 - "This study was a systematic review with meta-analysis examining the efficacy of carbohydrate (CHO) ingestion compared with placebo (PLA) on endurance exercise performance in adults. Relevant databases were searched to January 2011 ... time trial (TT) or exercise time to exhaustion (TTE) ... effect size (ES) ... The ES for submaximal exercise followed by TT was significant (ES = 0.53; 95% CI = 0.37-0.69; P < 0.001) as was the ES for TT (ES = 0.30; 95% CI = 0.07-0.53; P = 0.011). The weighted mean improvement in exercise performance favored CHO ingestion (7.5 and 2.0%, respectively). TTE (ES = 0.47; 95% CI = 0.32-0.62; P < 0.001) and submaximal exercise followed by TTE (ES = 0.44; 95% CI = 0.08-0.80; P = 0.017) also showed significant effects, with weighted mean improvements of 15.1 and 54.2%, respectively, with CHO ingestion. Similar trends were evident for subanalyses of studies using only male or trained participants, for exercise of 1-3 h duration, and where CHO and PLA beverages were matched for electrolyte content. The data support that ingestion of CHO between 30 and 80 g/h enhances endurance exercise performance in adults"

Adaptive dysfunction of selenoproteins from the perspective of the triage theory: why modest selenium deficiency may increase risk of diseases of aging - FASEB J. 2011 Mar 14 - "The triage theory proposes that modest deficiency of any vitamin or mineral (V/M) could increase age-related diseases. V/M-dependent proteins required for short-term survival and/or reproduction (i.e., "essential") are predicted to be protected on V/M deficiency over other "nonessential" V/M-dependent proteins needed only for long-term health. The result is accumulation of insidious damage, increasing disease risk. We successfully tested the theory against published evidence on vitamin K. Here, we review about half of the 25 known mammalian selenoproteins; all of those with mouse knockout or human mutant phenotypes that could be used as criteria for a classification of essential or nonessential. Five selenoproteins (Gpx4, Txnrd1, Txnrd2, Dio3, and Sepp1) were classified as essential and 7 (Gpx1, Gpx 2, Gpx 3, Dio1, Dio2, Msrb1, and SelN) nonessential. On modest selenium (Se) deficiency, nonessential selenoprotein activities and concentrations are preferentially lost, with one exception (Dio1 in the thyroid, which we predict is conditionally essential). Mechanisms include the requirement of a special form of tRNA sensitive to Se deficiency for translation of nonessential selenoprotein mRNAs except Dio1. The same set of age-related diseases and conditions, including cancer, heart disease, and immune dysfunction, are prospectively associated with modest Se deficiency and also with genetic dysfunction of nonessential selenoproteins, suggesting that Se deficiency could be a causal factor, a possibility strengthened by mechanistic evidence. Modest Se deficiency is common in many parts of the world; optimal intake could prevent future disease" - See selenium at Amazon.com.

  • The effectiveness of dried cranberries ( Vaccinium macrocarpon) in men with lower urinary tract symptoms Br J Nutr. 2010 Aug 31:1-9 - "In contrast to the control group, patients in the cranberry group had statistically significant improvement in International Prostate Symptom Score, QoL, urination parameters including voiding parameters (rate of urine flow, average flow, total volume and post-void residual urine volume), and lower total PSA level on day 180 of the study" - [Nutra USA]
  • Plasma Matrix Metalloproteinase (MMP)-9 Levels Are Reduced following Low-Calorie Cranberry Juice Supplementation in Men - J Am Coll Nutr. 2009 Dec;28(6):694-701 - "Matrix metalloproteinase (MMP)-9, also known as gelatinase B, is implicated in the development of hypertension and atherosclerotic plaque vulnerability to rupture, an important step in the etiology of cardiovascular diseases ... cranberry juice cocktail (CJC) ... We found that CJC supplementation significantly decreased plasma MMP-9 concentrations (mean +/- SEM: -36% +/- 9%, p < 0.0005; week 12 vs. baseline) while baseline plasma MMP-9 concentrations strongly correlated with the changes noted over the entire intervention (r = -0.71, p < 0.0001). We also show that the reduction in plasma MMP-9 levels was associated with a change in plasma nitrites/nitrates (NOx) concentration over the entire intervention (r = -0.38, p < 0.05; week 12 vs. baseline). Significant correlations were also noted between changes in plasma MMP-9 levels and those of systolic (r = 0.39, p < 0.05) and diastolic (r = 0.60, p < 0.001) blood pressure during the course of the study (week 12 vs. baseline). CONCLUSIONS: Our results show that daily CJC consumption is associated with a decrease in plasma MMP-9 concentrations in abdominally obese men. We hypothesize that polyphenolic compounds from cranberries may be responsible for this effect, supporting the notion that the consumption of flavonoid-rich foods can exert cardioprotective effects"
  • 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.
  • Effect of cranberry extracts on lipid profiles in subjects with Type 2 diabetes - Diabet Med. 2008 Dec;25(12):1473-7 - "Changes in lipid profiles, oxidized low-density lipoprotein (ox-LDL), glycaemic control, components of the metabolic syndrome, C-reactive protein (CRP) and urinary albumin excretion (UAE) were assessed after cranberry or placebo treatment for 12 weeks ... Low-density lipoprotein (LDL) cholesterol decreased significantly in the cranberry group (from 3.3 +/- 0.2 to 2.9 +/- 0.2 mmol/l, P = 0.005) and the decrease was significantly greater than that in the placebo group (-0.4 +/- 0.1 vs. 0.2 +/- 0.1 mmol/l, P < 0.001). Total cholesterol and total : high-density lipoprotein (HDL) cholesterol ratio also decreased significantly (P = 0.020 and 0.044, respectively) in the cranberry group and the reductions were significantly different from those in the placebo group (P < 0.001 and P = 0.032, respectively) ... Cranberry supplements are effective in reducing atherosclerotic cholesterol profiles, including LDL cholesterol and total cholesterol levels, as well as total : HDL cholesterol ratio, and have a neutral effect on glycaemic control in Type 2 diabetic subjects taking oral glucose-lowering agents"
  • Favourable impact of low-calorie cranberry juice consumption on plasma HDL-cholesterol concentrations in men - Br J Nutr. 2006 Aug;96(2):357-64 - "daily CJC consumption is associated with an increase in plasma HDL-cholesterol concentrations in abdominally obese men. We hypothesise that polyphenolic compounds from cranberries may be responsible for this effect, supporting the notion that the consumption of flavonoid-rich foods can be cardioprotective"
  • Potential of cranberry-based herbal synergies for diabetes and hypertension management - Asia Pac J Clin Nutr. 2006;15(3):433-41 - "The analysis of alpha -glucosidase,alpha -amylase, and ACE-I inhibitory activities suggested that inhibition depend on the phenolic profile of each unique extract and by bringing together synergistic combinations to cranberry, health beneficial functionality was enhanced. This enhanced functionality in terms of high alpha -glucosidase and alpha -amylase inhibitory activities indicate the potential for diabetes management, and high ACE-I inhibitory activity indicates the potential for hypertension management"
  • Efficacy of Cranberry Juice on Helicobacter pylori Infection: a Double-Blind, Randomized Placebo-Controlled Trial - Helicobacter. 2005 Apr;10(2):139-45 - "These results are significant ... Regular consumption of cranberry juice can suppress H. pylori infection in endemically afflicted populations"
