HEALTH BENEFITS OF CRANBERRIES

Cranberries (Vaccinium macrocarpon) are native to the boggy regions of temperate and subalpine North America and Europe. Although Native Americans used them extensively, they were first cultivated in the U.S. in the early 19th century. Cranberries grow on viney plants belonging to the heath family Ericaceae that also includes blueberries, bilberries, huckleberries, and bearberries (Arctostaphylos uva ursi). Cranberries contain tannins, fiber, anthocyanins (and other flavonoids), and Vitamin C. Their tannins prevent bacteria from attaching to cells. Consequently, cranberries have been used against infections, including urinary tract infections. In addition, cranberries may be helpful in protecting against heart disease and stroke.

Cranberry extract is an especially good source of antioxidant polyphenols. In animal studies, the polyphenols in cranberries have been found to decrease levels of total cholesterol and so-called “bad” cholesterol. Cranberries may also inhibit the growth of tumors in human breast tissue and lower the risk of both stomach ulcers and gum disease. 

Here is a list of the antioxidant and anti-inflammatory phytonutrients in found in cranberry extract.

OTHER CRANBERRY INFORMATION

    • Cranberries hold significantly high amounts of phenolic flavonoid phytochemicals called oligomeric proanthocyanidins (OPC’s). Scientific studies have shown that consumption of the berries have potential health benefits against cancer, aging and neurological diseases, inflammation, diabetes, and bacterial infections.
    • Antioxidant compounds in cranberry extract including OPC’s, anthocyanidin flavonoids, cyanidin, peonidin and quercetin may prevent cardiovascular disease by counteracting against cholesterol plaque formation in the heart and blood vessels. Further, these compounds help the human body lower LDL cholesterol levels and increase HDL-good cholesterol levels in the blood.
    • Scientific studies show that cranberry juice consumption offers protection against gram-negative bacterial infections such as E.coli in the urinary system by inhibiting bacterial-attachment to the bladder and urethra.
    • It is known that cranberries turns urine acidic. This, together with the inhibition of bacterial adhesion helps prevent the formation of alkaline (calcium ammonium phosphate) stones in the urinary tract by working against proteus bacterial-infections.
    • In addition, the berries prevent plaque formation on the tooth enamel by interfering with the ability of the gram-negative bacterium, Streptococcus mutans, to stick to the surface. In this way cranberries helps prevent the development of cavities.
    • The berries are also good source of many vitamins like vitamin C, vitamin A, ß-carotene, lutein, zea-xanthin, and folate and minerals like potassium, and manganese.
  • Oxygen Radical Absorbance Capacity (ORAC) demonstrates cranberry at an ORAC score of 9584 µmol TE units per 100 g, one of the highest in the category of edible berries.

SCIENTIFIC STUDIES ON THE ANTIOXIDANT EFFECTS OF CRANBERRIES

Below, I provide relevant scientific studies on the antioxidant effects and potential health benefits of cranberries.

PREVENTION OF OXIDATIVE STRESS, INFLAMMATION AND MITOCHONDRIAL DYSFUNCTION IN THE INTESTINE BY DIFFERENT CRANBERRY PHENOLIC FRACTIONS.

ABSTRACT

Cranberry fruit has been reported to have high antioxidant effectiveness that is potentially linked to its richness in diversified polyphenolic content. The aim of the present study was to determine the role of cranberry polyphenolic fractions in oxidative stress (OxS), inflammation and mitochondrial functions using intestinal Caco-2/15 cells. The combination of HPLC and UltraPerformance LC®-tandem quadrupole (UPLC-TQD) techniques allowed us to characterize the profile of low, medium and high molecular mass polyphenolic compounds in cranberry extracts. The medium molecular mass fraction was enriched with flavonoids and procyanidin dimers whereas procyanidin oligomers (DP > 4) were the dominant class of polyphenols in the high molecular mass fraction. Pre-incubation of Caco-2/15 cells with these cranberry extracts prevented iron/ascorbate-mediated lipid peroxidation and counteracted lipopolysaccharide-mediated inflammation as evidenced by the decrease in pro-inflammatory cytokines (TNF-α and interleukin-6), cyclo-oxygenase-2 and prostaglandin E2. Cranberry polyphenols (CP) fractions limited both nuclear factor κB activation and Nrf2 down-regulation. Consistently, cranberry procyanidins alleviated OxS-dependent mitochondrial dysfunctions as shown by the rise in ATP production and the up-regulation of Bcl-2, as well as the decline of protein expression of cytochrome c and apoptotic-inducing factor. These mitochondrial effects were associated with a significant stimulation of peroxisome-proliferator-activated receptor γ co-activator-1-α, a central inducing factor of mitochondrial biogenesis and transcriptional co-activator of numerous downstream mediators. Finally, cranberry procyanidins forestalled the effect of iron/ascorbate on the protein expression of mitochondrial transcription factors (mtTFA, mtTFB1, mtTFB2). Our findings provide evidence for the capacity of CP to reduce intestinal OxS and inflammation while improving mitochondrial dysfunction.

 CHEMICAL CHARACTERIZATION AND CHEMO-PROTECTIVE ACTIVITY OF CRANBERRY PHENOLIC POWDERS IN A MODEL CELL CULTURE. RESPONSE OF THE ANTIOXIDANT DEFENSES AND REGULATION OF SIGNALING PATHWAYS

ABSTRACT

Oxidative stress and reactive oxygen species (ROS)-mediated cell damage are implicated in various chronic pathologies. Emerging studies show that polyphenols may act by increasing endogenous antioxidant defense potential. Cranberry has one of the highest polyphenol content among commonly consumed fruits. In this study, the hepato-protective activity of a cranberry juice (CJ) and cranberry extract (CE) powders against oxidative stress was screened using HepG2 cells, looking at ROS production, intracellular non-enzymatic and enzymatic antioxidant defenses by reduced glutathione concentration (GSH), glutathione peroxidase (GPx) and glutathione reductase (GR) activity and lipid peroxidation biomarker malondialdehyde (MDA). Involvement of major protein kinase signaling pathways was also evaluated. Both powders in basal conditions did not affect cell viability but decreased ROS production and increased GPx activity, conditions that may place the cells in favorable conditions against oxidative stress. Powder pre-treatment of HepG2 cells for 20 h significantly reduced cell damage induced by 400 μM tert-butylhydroperoxide (t-BOOH) for 2 h. Both powders (5–50 μg/ml) reduced t-BOOH-induced increase of MDA by 20% (CJ) and 25% (CE), and significantly reduced over-activated GPx and GR. CE, with a significantly higher amount of polyphenols than CJ, prevented a reduction in GSH and significantly reduced ROS production. CJ reversed the t-BOOH-induced increase in phospho-c-Jun N-terminal kinase. This study demonstrates that cranberry polyphenols may help protect liver cells against oxidative insult by modulating GSH concentration, ROS and MDA generation, antioxidant enzyme activity and cell signaling pathways.

CRANBERRY EXTRACT SUPPRESSES INTERLEUKIN-8 SECRETION FROM STOMACH CELLS STIMULATED BY HELICOBACTER PYLORI IN EVERY CLINICALLY SEPARATED STRAIN BUT INHIBITS GROWTH IN PART OF THE STRAINS

From: http://www.sciencedirect.com/science/article/pii/S1756464613000364

ABSTRACT

It is known that cranberry inhibits the growth of Helicobacter pylori (HP). In human stomach, HP basically induces chronic inflammation by stimulating stomach cells to secrete interleukin (IL)-8 and other inflammatory cytokines, and causes stomach cancer, etc. The aim of this study was to investigate the inhibiting effects of cranberry on HP growth and IL-8 secretion from stomach cells induced by HP, using clinically separated HP strains. HP growth in liquid culture and on-plate culture was evaluated by titration after 2-day incubation and by agar dilution technique, respectively. For IL-8 experiments, MKN-45, a stomach cancer cell line, was incubated with HP for 24 h and IL-8 in the medium was assayed by ELISA. Cranberry suppressed growth of the bacteria only in six of the 27 strains. Meanwhile, it suppressed IL-8 secretion in all the strains. The results may suggest a possible role of cranberry in prevention of stomach cancer by reducing gastric inflammation.

EFFECTS OF CRANBERRY POWDER ON BIOMARKERS OF OXIDATIVE STRESS AND GLUCOSE CONTROL IN DB/DB MICE

From: http://www.ncbi.nlm.nih.gov/pubmed/24353827

ABSTRACT

Increased oxidative stress in obese diabetes may have causal effects on diabetic complications, including dyslipidemia. Lipopolysccharides (LPS) along with an atherogenic diet have been found to increase oxidative stress and insulin resistance. Cranberry has been recognized as having beneficial effects on diseases related to oxidative stress. Therefore, we employed obese diabetic animals treated with an atherogenic diet and LPS, with the aim of examining the effects of cranberry powder (CP) on diabetic related metabolic conditions, including lipid profiles, serum insulin and glucose, and biomarkers of oxidative stress. Forty C57BL/KsJ-db/db mice were divided into the following five groups: normal diet + saline, atherogenic diet + saline, atherogenic diet + LPS, atherogenic diet + 5% CP + LPS, and atherogenic diet + 10% CP + LPS. Consumption of an atherogenic diet resulted in elevation of serum total cholesterol and atherogenic index (AI) and reduction of high density lipoprotein (HDL)-cholesterol. However, with 10% CP, the increase in mean HDL-cholesterol level was close to that of the group with a normal diet, whereas AI was maintained at a higher level than that of the group with a normal diet. LPS induced elevated serum insulin level was lowered by greater than 60% with CP (P < 0.05), and mean serum glucose level was reduced by approximately 19% with 5% CP (P > 0.05). Mean activity of liver cytosolic glutathione peroxidase was significantly increased by LPS injection, however it was reduced back to the value without LPS when the diet was fortified with 10% CP (P < 0.05). In groups with CP, a reduction in mean levels of serum protein carbonyl tended to occur in a dose dependent manner. Particularly with 10% CP, a reduction of approximately 89% was observed (P > 0.05). Overall results suggest that fortification of the atherogenic diet with CP may have potential health benefits for obese diabetes with high oxidative stress, by modulation of physical conditions, including some biomarkers of oxidative stress.

ULTIMATE PROTECTOR+ INGREDIENTS – APPLE

Dr. Hank Liers, PhD biography about us HPDI integratedhealth formulator founder CEO scientist physicist wild bilberry and wild blueberry Ultimate Protector+ includes apple extract, as well as extracts from 12 different fruits, vegetables, and herbs. Each of these ingredients contain substances considered to be polyphenols, antioxidants, and Nrf2 activators. In this article, I explore the ingredient apple (Malus pumila mill.) extract, which is a component of SFB® – Standardized Fruit Blend from Ethical Naturals, Inc.

apple extract

Ultimate Protector+ Includes Apple

SFB® is a proprietary formula that combines extracts from Grape, Cranberry, Pomegranate, Blueberry, Apple, Mangosteen, Bilberry, Chokeberry, and Goji Berry. It is high in fruit polyphenols, flavonoids, anthocyanins, catechins, proanthocyanins, ellagic acid, xanthines, chlorogenic acid, pterostilbenes, resveratrol, phloridzin, quercetin, zeaxanthin, and quinic acid. With its diverse blend, SFB® offers over 40-50% polyphenols as well as >9,000 ORAC units in a single gram.

Polyphenols, anthocyanins and other plant elements are powerful ingredients associated with a variety of areas of human health, including healthy aging, healthy glucose metabolism, cardiovascular health, and inflammation management.

HEALTH BENEFITS OF APPLE

The Apple extract in Ultimate Protector+ has been extracted with non-GMO food grade ethanol and distilled water. Testing has indicated the product contains over 40% polyphenols. In numerous epidemiological studies, apples have been associated with a decreased risk of chronic diseases such as cardiovascular disease, cancer, and asthma.

When compared to many other commonly consumed fruits in the United States, apples had the second highest level of antioxidant activity. Apples also ranked the second for total concentration of phenolic compounds, and perhaps more importantly, apples had the highest portion of free phenolics when compared to other fruits.

APPLE PHYTOCHEMICALS

Apples contain a large concentration of flavonoids, as well as a variety of other phytochemicals, and the concentration of these phytochemicals may depend on many factors, such as cultivar of the apple, harvest and storage of the apples, and processing of the apples. The concentration of phytochemicals also varies greatly between the apple peels and the apple flesh.

Some of the most well studied antioxidant compounds in apples include quercetin-3-galactoside, quercetin-3-glucoside, quercetin-3-rhamnoside, catechin, epicatechin, procyanidin, cyanidin-3-galactoside, coumaric acid, chlorogenic acid, gallic acid, and phloridzin. Recently researchers have examined the average concentrations of the major phenolic compounds in six cultivars of apples. They found that the average phenolic concentrations among the six cultivars were: quercetin glycosides, 13.2 mg/100 g fruit; vitamin C, 12.8 mg/100 g fruit; procyanidin B, 9.35 mg/100 g fruit; chlorogenic acid, 9.02 mg/100 g fruit; epicatechin, 8.65 mg/100 g fruit; and phloretin glycosides, 5.59 mg/100 g fruit.

The compounds most commonly found in apple peels consist of the procyanidins, catechin, epicatechin, chlorogenic acid, phloridzin, and the quercetin conjugates. In the apple flesh, there is some catechin, procyanidin, epicatechin, and phloridzin, but these compounds are found in much lower concentrations than in the peels. Quercetin conjugates are found exclusively in the peel of the apples. Chlorogenic acid tends to be higher in the flesh than in the peel.

Because the apple peels contain more antioxidant compounds, especially quercetin, apple peels may have higher antioxidant activity and higher bioactivity than the apple flesh. Research showed that apples without the peels had less antioxidant activity than apples with the peels. Apples with the peels were also better able to inhibit cancer cell proliferation when compared to apples without the peels. More recent work has shown that apple peels contain anywhere from two to six times (depending on the variety) more phenolic compounds than in the flesh, and two to three times more flavonoids in the peels when compared to the flesh. The antioxidant activity of these peels was also much greater, ranging from two to six times greater in the peels when compared to the flesh, depending on the variety of the apple. This work is supported a study which found that rats consuming apple peels showed greater inhibition of lipid peroxidation and greater plasma antioxidant capacity when compared to rats fed apple flesh.

Many of these phytochemicals from apples have been widely studied, and many potential health benefits have been attributed to these specific phytochemicals. The procyanidins, epicatechin and catechin, have strong antioxidant activity and have been found to inhibit low density lipoprotein (LDL) oxidation in vitro. In mice, catechin inhibits intestinal tumor formation and delays tumors onset. One  study found that chlorogenic acid has very high alkyl peroxyl radical (ROO•) scavenging activity. Compared to about 18 other antioxidant compounds (including quercetin, gallic acid, α-tocopherol), chlorogenic was second only to rutin. Since ROO• may enhance tumor promotion and carcinogenesis, chlorogenic acid may add to the protective effect of apples against cancer. Chlorogenic acid has been found to inhibit 8-dehydroxy-deoxyguanosine formation in cellular DNA in a rat model following treatment with 4-nitroquinoline-1-oxide.

Quercetin is also a strong antioxidant, and is thought to have potential protective effects against both cancer and heart disease. Briefly, quercetin has been found to down regulate expression of mutant p53 in breast cancer cells, arrest human leukemic T-cells in G1, inhibit tyrosine kinase, and inhibit heat shock proteins. Quercetin has protected Caco-2 cells from lipid peroxidation induced by hydrogen peroxide and Fe2+. In mice liver treated with ethanol, quercetin decreased lipid oxidation and increased glutathione, protecting the liver from oxidative damage. Recently, it has been found that high doses of quercetin inhibit cell proliferation in colon carcinoma cell lines and in mammary adenocarcinoma cell lines, but at low doses quercetin increased cell proliferation (20% in colon cancer cells and 100% in breast cancer cells). However, low doses of quercetin (10 uM) inhibited cell proliferation in Mol-4 Human Leukemia cells and also induced apoptosis. Quercetin inhibited intestinal tumor growth in mice, but not in rats. Low levels of quercetin inhibited platelet aggregation, calcium mobilization, and tyrosine protein phosphorylation in platelets. Modulation of platelet activity may help prevent cardiovascular disease.

Apple phytochemicals and their health benefits

Jeanelle Boyer1 and Rui Hai Liu1

Abstract

Evidence suggests that a diet high in fruits and vegetables may decrease the risk of chronic diseases, such as cardiovascular disease and cancer, and phytochemicals including phenolics, flavonoids and carotenoids from fruits and vegetables may play a key role in reducing chronic disease risk. Apples are a widely consumed, rich source of phytochemicals, and epidemiological studies have linked the consumption of apples with reduced risk of some cancers, cardiovascular disease, asthma, and diabetes. In the laboratory, apples have been found to have very strong antioxidant activity, inhibit cancer cell proliferation, decrease lipid oxidation, and lower cholesterol. Apples contain a variety of phytochemicals, including quercetin, catechin, phloridzin and chlorogenic acid, all of which are strong antioxidants. The phytochemical composition of apples varies greatly between different varieties of apples, and there are also small changes in phytochemicals during the maturation and ripening of the fruit. Storage has little to no effect on apple phytochemicals, but processing can greatly affect apple phytochemicals. While extensive research exists, a literature review of the health benefits of apples and their phytochemicals has not been compiled to summarize this work. The purpose of this paper is to review the most recent literature regarding the health benefits of apples and their phytochemicals, phytochemical bioavailability and antioxidant behavior, and the effects of variety, ripening, storage and processing on apple phytochemicals..

Cancer chemopreventive potential of apples, apple juice, and apple components.

Abstract

Apples ( MALUS sp., Rosaceae) are a rich source of nutrient as well as non-nutrient components and contain high levels of polyphenols and other phytochemicals. Main structural classes of apple constituents include hydroxycinnamic acids, dihydrochalcones, flavonols (quercetin glycosides), catechins and oligomeric procyanidins, as well as triterpenoids in apple peel and anthocyanins in red apples. Several lines of evidence suggest that apples and apple products possess a wide range of biological activities which may contribute to health beneficial effects against cardiovascular disease, asthma and pulmonary dysfunction, diabetes, obesity, and cancer (reviewed by Boyer and Liu, Nutr J 2004). The present review will summarize the current knowledge on potential cancer preventive effects of apples, apple juice and apple extracts (jointly designated as apple products). In brief, apple extracts and components, especially oligomeric procyanidins, have been shown to influence multiple mechanisms relevant for cancer prevention in IN VITRO studies. These include antimutagenic activity, modulation of carcinogen metabolism, antioxidant activity, anti-inflammatory mechanisms, modulation of signal transduction pathways, antiproliferative and apoptosis-inducing activity, as well as novel mechanisms on epigenetic events and innate immunity. Apple products have been shown to prevent skin, mammary and colon carcinogenesis in animal models. Epidemiological observations indicate that regular consumption of one or more apples a day may reduce the risk for lung and colon cancer.

Abstract

Since gastrointestinal mucosa is constantly exposed to reactive oxygen species from various sources, the presence of antioxidants may contribute to the body’s natural defenses against inflammatory diseases.

Hypothesis

To define the polyphenols extracted from dried apple peels (DAPP) and determine their antioxidant and anti-inflammatory potential in the intestine. Caco-2/15 cells were used to study the role of DAPP preventive actions against oxidative stress (OxS) and inflammation induced by iron-ascorbate (Fe/Asc) and lipopolysaccharide (LPS), respectively.

Results

The combination of HPLC with fluorescence detection, HPLC-ESI-MS TOF and UPLC-ESI-MS/MS QQQ allowed us to characterize the phenolic compounds present in the DAPP (phenolic acids, flavonol glycosides, flavan-3-ols, procyanidins). The addition of Fe/Asc to Caco-2/15 cells induced OxS as demonstrated by the rise in malondialdehyde, depletion of n-3 polyunsaturated fatty acids, and alterations in the activity of endogenous antioxidants (SOD, GPx, G-Red). However, preincubation with DAPP prevented Fe/Asc-mediated lipid peroxidation and counteracted LPS-mediated inflammation as evidenced by the down-regulation of cytokines (TNF-α and IL-6), and prostaglandin E2. The mechanisms of action triggered by DAPP induced also a down-regulation of cyclooxygenase-2 and nuclear factor-κB, respectively. These actions were accompanied by the induction of Nrf2 (orchestrating cellular antioxidant defenses and maintaining redox homeostasis), and PGC-1α (the “master controller” of mitochondrial biogenesis).

Conclusion

Our findings provide evidence of the capacity of DAPP to reduce OxS and inflammation, two pivotal processes involved in inflammatory bowel diseases.

Cranberry extract suppresses interleukin-8 secretion from stomach cells stimulated by Helicobacter pylori in every clinically separated strain but inhibits growth in part of the strains

From: http://www.sciencedirect.com/science/article/pii/S1756464613000364

Abstract

It is known that cranberry inhibits the growth of Helicobacter pylori (HP). In human stomach, HP basically induces chronic inflammation by stimulating stomach cells to secrete interleukin (IL)-8 and other inflammatory cytokines, and causes stomach cancer, etc. The aim of this study was to investigate the inhibiting effects of cranberry on HP growth and IL-8 secretion from stomach cells induced by HP, using clinically separated HP strains. HP growth in liquid culture and on-plate culture was evaluated by titration after 2-day incubation and by agar dilution technique, respectively. For IL-8 experiments, MKN-45, a stomach cancer cell line, was incubated with HP for 24 h and IL-8 in the medium was assayed by ELISA. Cranberry suppressed growth of the bacteria only in six of the 27 strains. Meanwhile, it suppressed IL-8 secretion in all the strains. The results may suggest a possible role of cranberry in prevention of stomach cancer by reducing gastric inflammation.

Effects of cranberry powder on biomarkers of oxidative stress and glucose control in db/db mice

From: http://www.ncbi.nlm.nih.gov/pubmed/24353827

Abstract

Increased oxidative stress in obese diabetes may have causal effects on diabetic complications, including dyslipidemia. Lipopolysccharides (LPS) along with an atherogenic diet have been found to increase oxidative stress and insulin resistance. Cranberry has been recognized as having beneficial effects on diseases related to oxidative stress. Therefore, we employed obese diabetic animals treated with an atherogenic diet and LPS, with the aim of examining the effects of cranberry powder (CP) on diabetic related metabolic conditions, including lipid profiles, serum insulin and glucose, and biomarkers of oxidative stress. Forty C57BL/KsJ-db/db mice were divided into the following five groups: normal diet + saline, atherogenic diet + saline, atherogenic diet + LPS, atherogenic diet + 5% CP + LPS, and atherogenic diet + 10% CP + LPS. Consumption of an atherogenic diet resulted in elevation of serum total cholesterol and atherogenic index (AI) and reduction of high density lipoprotein (HDL)-cholesterol. However, with 10% CP, the increase in mean HDL-cholesterol level was close to that of the group with a normal diet, whereas AI was maintained at a higher level than that of the group with a normal diet. LPS induced elevated serum insulin level was lowered by greater than 60% with CP (P < 0.05), and mean serum glucose level was reduced by approximately 19% with 5% CP (P > 0.05). Mean activity of liver cytosolic glutathione peroxidase was significantly increased by LPS injection, however it was reduced back to the value without LPS when the diet was fortified with 10% CP (P < 0.05). In groups with CP, a reduction in mean levels of serum protein carbonyl tended to occur in a dose dependent manner. Particularly with 10% CP, a reduction of approximately 89% was observed (P > 0.05). Overall results suggest that fortification of the atherogenic diet with CP may have potential health benefits for obese diabetes with high oxidative stress, by modulation of physical conditions, including some biomarkers of oxidative stress.
