Fresh apples contain about 15% total carbohydrate. This study focused on a single concentration of one isolated compound; an expansion of work with this model using a wider range of concentrations and varied phytochemicals would be of interest. I thought it might be interesting to list the top 20 organic and inorganic compounds of something like an . It has been proposed that assessment of total oxidant scavenging activity might overcome the inconsistencies observed in other assays. The relevance of this study relates to the reduced ability of larger molecules in polymeric form to be absorbed in the upper segment of the intestine, resulting in a higher residual concentration in the colon. Commercial apple juice in Germany was tested among other fruit juices. The women were randomized to 1 of 3 diet groups for 10 wk including a daily intake of 300 g of apple (~1.5 large size), daily intake of a similar quantity of pear, or 60 g of oat cookies. Plasma levels of HDL cholesterol increased and liver TG content decreased, although plasma TG levels were somewhat higher. 37 First, 150 L of a CHE extract aqueous solution (1 mg mL 1), 150 L of Folin-Ciocalteu reagent, 600 L of water and 1500 L of sodium carbonate solution (7% w/v) were mixed.The reaction mixture was stirred for five minutes and stored in the dark . Another in vitro study with AP demonstrated that there may be other beneficial effects to gastrointestinal health by an alternate mechanism of reducing risk of mutagenesis in gastric cancer (77). Ink. A new report using data from the French branch of the European Prospective Investigation into Cancer and Nutrition trial provided evidence of a link between apple intake and reduced asthma prevalence in a sample of 68,535 adult women, mostly teachers, enrolled in a national health insurance plan (52). Author disclosure: D.A. A case-control study from the UK also did not show a protective effect of apples on risk of developing asthma (58). These include the diet-related conditions of hypertension, coronary artery disease, myocardial infarction, angina, heart failure, and stroke (33). Polyphenolic concentration of whole apples (freeze dried) and apple juice. The data are presented in the context of colon cancer, followed by breast cancer and general studies. Very good resistance to stress corrosion cracking (SCC) and intergranular corrosion in various environments. After apple consumption, FRAP increased significantly by 12% at 1 h and plasma levels of ascorbate and urate also increased. In spite of the similar chemical composition between some extracts, the antioxidant capacity determined by Trolox equivalent antioxidant capacity differed, suggesting that there are unknown compounds accounting for the observed antioxidant effects of AP. Its chemical formula is C 10 H 10 O 4. Understanding and characterizing the bioavailability of AP in humans is important in examining their possible protective effects on colon cancer. Nutrient Composition of Hawthorn. I thank Sue Taylor and Stacie Haaga for their helpful discussion and review. One widely studied mechanism related to cancer is oxidation. The cells were exposed to apple extracts, prepared from fresh fruit (assayed for total phenolic and flavonoid content) across several ranges from 0 to 60 g/L. Lichtenthaler et al. An estimated 10 million Americans over age 50 y have osteoporosis and another 34 million are at risk (71). Hamsters were provided with apples to approximate human intake of 600 g/d (~2.5 large apples) or 500 mL of juice/d. Blanching of apple puree, on the other hand, increased apple juice turbidity by increasing the amount of . A physical property is a characteristic of matter that is not associated with a change in its chemical composition. After 80 d of treatment, it was found that phloridzin intake improved femoral bone mineral density and markers of bone turnover. (42). VDOMDHTMLtml> What is the chemical composition for apple? It was found that the accumulation of esterified cholesterol decreased and the secretion of apo-B (B-48 and B-100) containing lipoproteins was reduced. Apple cider vinegar is 94% water and 5% acetic acid with 1% carbohydrates and no fat or protein (table). The antioxidant mechanisms described in many studies have important implications for a protective effect of AP on not only cancer but also cardiovascular disease, Alzheimer's disease, asthma, and potentially diabetes. The upregulation of these enzymes suggests that regular apple consumption might promote a favorable milieu to reduce oxidation. As reviewed by Boyer and Liu (1), there were several reports prior to 2004 demonstrating that AP intake was associated with reduced risk of cancer, particularly lung cancer in cohort and case-control studies. The strengths of this diet study included the use of whole fruits rather than extracts in addition to the easily achievable energy level of the weight loss regime and the involvement of a registered dietitian to implement the diet. Although the SCFA were not correlated with inhibition of growth in this study, it is known that SCFA can stimulate pathways of growth arrest, differentiation, and apoptosis. The influence of farming systems on the harvest of apple tree orchards and the chemical composition of apples S. Nominaitis1, V. M. Rutkoviene1, P. Vikelis 2 Key words: genus, scab, skin toughness, picking maturity, fruit quality Summary: Research of apple productivity and quality was carried out in organic and intensive It has also been proposed that dihydrochalcones, particularly phloretin-2-0-glucoside present in relatively high amounts in AP, inhibit sodium-dependent glucose transporters in the intestinal lumen, therefore potentially reducing postprandial glucose response (68, 69). There was a concurrent and dose-dependent increase in expression of Bax, a proapoptotic protein and downward expression of Bcl-2, an antiapoptotic protein. Follow-up work with this model to further characterize the effects of the fresh apple extract demonstrated dose-dependent inhibition of markers of cell proliferation (proliferating cell nuclear antigen) and down regulation of the cell cycle in mammary tumor cells (cyclin D1 protein expression) (28). Apples and AP3, including juices and extracts, have been included in health-related studies around the world due to their rich content of varied phytochemicals. In this study, human breast cancer cells (MCF-7) were exposed to TNF (10 g/L) to activate NF-B. How Odor Works Iodine solution, alcohol solution. Several studies, summarized below, have attempted to elucidate specific antioxidant components in AP using in vitro assays. We can found it in plant cell wall. If it's edible then it's chemicals. 3 comments. It has been proposed that an integrated approach incorporating antioxidant capacity values from several different assays in a validated statistical model might provide a more accurate assessment of the relative antioxidant capacity of foods (46). Recent data support these findings, particularly those related to asthma. As such, it would be inaccurate to conclusively state that apples alone induce weight loss on the basis of this study. Apple juice preparations, including a cloudy (higher procyanidin and pectin) and a clear juice preparation, reduced important markers, including DNA damage and hyperproliferation and lowered the number of large aberrant crypt foci in the distal colon. Further investigation of the in vivo effects of AP as well as other sources of antioxidants relative to antioxidant status is relevant and warranted. Polysaccharides extracted from mulberry fruits (Morus nigra L.): antioxidant effect of ameliorating H. Predictors and characteristics of Rib fracture following SBRT for lung tumors. The effect was mediated by apple phenolics but particularly chlorogenic acid and (+)-catechin (5 mol/L). Tsao R, Yang R, Xie S, Sockovie E, Khanizadeh S, Chun OK, Kim D-O, Smith N, Schroeder D, Han J, Lee C, Sampson L, Rimm E, Hollman P, deVries J, Katan M, Hertog MG, Feskens E, Hollman P, Katan MB, Kromhout D, Veeriah S, Hofmann T, Glei M, Dietrich H, Will F, Schreier P, Knaup B, Pool-Zobel BL, Gallus S, Talamini R, Giacosa A, Montella M, Ramazzotti V, Franceschi S, Negri E, La Vecchia C. Linseisen J, Rohrmann S, Miller A, Bas Bueno-de-Mesquita H, Bchner F, Vineis P, Agudo A, Gram I, Janson L, Krogh V, et al. Results expressed on dry matter basis revealed the seeds contained the following: 2.74% protein, 15.86% crude fat, 7.67% crude fiber, 468.74kcal, 82.01% moisture content, 5.72% ash, 88.98% carbohydrate. freshly squeezed orange juice. The authors concluded that these compounds could be partially responsible for the anticancer activities associated with AP. Incubating SW620 cells with an apple extract selected for procyanidins (mainly polymeric molecules) resulted in a dose-dependent inhibition of cell growth. Elevated lipids and aberrations in lipid metabolism are well-established risk factors for many types of cardiovascular disease. Chemical composition of apple fruits of eight cultivars Results as mean SEM of triplicate measurements. Apple feeding significantly reduced the concentration of the oxidative marker MDA in urine to levels lower than those in healthy control animals. In particular, apple juice concentrate prevents the characteristic decline in acetylcholine associated with aging and oxidative stress (62). The influence of farming systems on the harvest of apple tree orchards and the chemical composition of apples S. Nominaitis1, V. M. Rutkoviene1, P. Vikelis 2 Key words: genus, scab, skin toughness, picking maturity, fruit quality Summary: Research of apple productivity and quality was carried out in organic and intensive It is thought that lungs are particularly susceptible to oxidative damage due to high and continual exposure to oxygen. In a recent study using Caco-2 cells, it was found that an apple juice extract devoid of carbohydrates, acids, and other native compounds attenuated experimentally induced expression of cytochrome P450 1A1 and inhibited catalytic activity of the enzyme. A great deal of work has focused on dietary polyphenols, particularly the most abundant subclasses, including flavonoids (60% of all polyphenols) and phenolic acids (30% of total polyphenols) (2). 2.1. In follow-up studies, the same authors examined the effect of isolated fractions on the above markers and concluded that the juice fraction itself was more effective than individual components of juice, including polyphenolic-rich extracts (18). TheOutcast06 3 yr. ago. I have been fighting the naturalistic fallacy lately and I seem to remember a picture of an apple with a list of compounds which I assumed were naturally occurring - I seem to remember it was a motivational type. High resistance to pitting and crevice corrosion. The combined phytochemical and nutrient profiles in AP suggests their potential to be powerful in the prevention of several chronic conditions in humans. It is becoming apparent that native polyphenolic compounds are most commonly tested but due to extensive metabolic modification, the ingested compounds may be negligible or even absent in tissues under physiologic conditions. A detailed report of apple phytochemicals and their health benefits was published by Boyer and Liu (1) in 2004. Additional work from this laboratory using mice with genetically induced oxidative stress (an ApoE-deficient strain) showed that 1 mo of apple juice concentrate intake reduced the accumulation of ROS in brain tissue and attenuated cognitive impairment (60, 61). Based on this premise, a study was conducted in Brazil on 49 overweight women with high blood cholesterol levels to determine the effect of fruit intake on blood lipids and body weight (70). Exposure to apples and apple products has been associated with beneficial effects on risk, markers, and etiology of cancer, cardiovascular disease, asthma, and Alzheimer's disease. 1. The fermentation products of the apple juice extract in combination with pectin included acetate, propionate, and butyrate, the latter of which was most significantly correlated with histone deacylation inhibition. A series of recent studies from the laboratory of Shea et al. (20) crushed and extracted juice from cider and table apples harvested in Germany to prepare several polyphenolic mixtures, including one extract from apple pomace. The potential of AP phytochemicals to reduce disease risk and improve health has caught the attention of scientists, practitioners, and the lay public. Oxidant stress also activates inflammatory mediators that induce asthma in experimental models and appears to be important in the etiology of asthma in humans (51). Ongoing work continues to further delineate multiple mechanisms by which AP might be protective and suggests great promise. In this study, we propose a novel method that utilizes hyperspectral imaging (HSI) technology to non-destructively monitor ApMV-infected apple leaves and predict LCC as a quantitative indicator of disease . AP might be protective because of their antioxidant potential and phytochemical content. Hyson, no conflicts of interest. Validated FFQ including 208 food items and photographic prompts were used to determine dietary intake and categorize food into quartiles. The processes associated with aging and amplified in neurodegenerative diseases of aging are complex and not completely understood. Histological analysis showed that consumption of the apple extract also reduced the proportion of highly malignant adenocarcinoma in a dose-dependent manner from 81.3% in the control group to ~57, 50, and 23% in the low, middle, and high doses of apple extracts, respectively, over 24 wk. More than 4000 flavonoids have been identified and all share a common carbon skeleton structure (C6-C3-C6). Chemical Properties of Anthocyanins in Black Foods The basic C6-C3-C6 anthocyanin structure is the combination of anthocyanidins (aglycones) linking with sugars, which can be separated into anthocyanidin sugar-free aglycones and anthocyanin glycosides depending on structure [10]. Other disease-related processes that are reportedly influenced by AP include cell proliferation and tumor production, inflammatory responses, apoptosis, cell differentiation (11), platelet aggregation, lipid metabolism, cell adhesion molecule expression, and endothelial function, among others (12). Very preliminary in vitro evidence indicates that compounds from AP could be protective against gastric ulcer. Adapted with permission from (4). Every triterpenoid significantly suppressed cancer cell proliferation; some were highly potent and reduced cell growth by 50% at relatively low concentrations (~1017 mol/L). Does an apple a day keep the oncologist away? Because early lesions in the colon may progress to malignancy, the presence of premalignant hyperproliferative crypts and aberrant crypts are indicators of the potential pathogenesis of cancer in this model. The fresh peeled apple meal included 311 g of unpeeled apple plus a protein drink and 53 g of candy; the applesauce test meal included 877.5 g of unsweetened canned applesauce and a protein drink and the control meal included just the candy (108 g) and the protein drink. Although total daily apple intake was not reported in this small study, it is estimated that the average intake would not be much more than 1 small apple/d (149 g) based on a conservative speculated average bodyweight range of 6070 kg. The apple extract significantly inhibited cell proliferation and downregulated cell cycle protein expression. There was a 50% inhibition at a concentration of 45 g/mL and total inhibition at 70 g/mL. Although further work is needed to extrapolate these findings to clinical outcomes, it is promising that there are multiple plausible mechanisms by which AP intake might reduce the risk of cancer in humans. However, the authors suggest that more work remains to fully understand the effects of hydrolysis on antioxidant capacity in AP. Both products also reduced the percentage of aortic surface area covered by foam cells (aortic fatty streak lesion area) by 48% in the apple group and 60% in the apple juice group compared to controls. These findings were consistent with prior data showing reduced coronary mortality in elderly Dutch men (6584 y) who consumed apples (average 69 g/d) compared to men who had little or no apple intake (35). In a large ongoing trial, the Women's Health Study, semiquantitative FFQ were analyzed to determine if dietary flavonoid intake was associated with risk of diabetes and related markers of insulin resistance and inflammation (67). It was shown that extensive isomerization, cleavage, and conjugation of the native polyphenolic compounds occurred. Shea et al. The fraction highest in catechin also protected cells from oxidative damage in a dose-dependent manner with a maximal protective effect at 3 h. The protective effect was associated with a corresponding increase in antioxidant activity and reduced lipid peroxidation per measurement of MDA. This is of importance, because many flavonoids and dihydrocalchones are present in intact plant foods as glycosides with saccharide residues, but during processing and storage hydrolysis occurs, leading to the aglycone form. There have also been several studies that examined the potential of AP to reduce breast cancer risk. There were also differential outcomes between cell lines in terms of the inhibitory effect of the anthocyanidin-rich fraction, with significant inhibition in the HT29 cells by apple anthocyanidins (compared to an actual increase in proliferation in response to this fraction in MCF-7 cells). In vitro studies from the above laboratory examined the potential mechanisms by which AP may cause reduction in mammary tumors (29). Although data relating AP intake to reduced risk of asthma are provocative, there are some inconsistent reports. Typically, the greater values in the ranges shown for juices reflect the higher concentration of polyphenols in fresh juice prepared from cider apples and commercial preparations of cloudy juice compared to lower quantities in fresh juice made with dessert apple varieties or commercial juices that are clear. Identify each substance as a compound, an element, a heterogeneous mixture, or a homogeneous mixture (solution). It has been shown that the estrogen decline associated with menopause is linked to increased production of inflammatory mediators within the bone microenvironment. In a study of SW620, adenocarcinoma-derived metastatic cells of colon cancer, the goal was to determine whether polymeric apple phenols compared to monomeric forms were more effective in attenuating cell proliferation (19). Similar results were found in cells exposed to an enriched extract of procyanidins (flavanols, catechin, and epicatechin). Barth et al. Polyamines, as regulators of cell function, have important potential in cancer by either promoting cell proliferation or cell death depending on the cell type. Several recent intervention studies have examined the effect of fresh apple consumption on oxidative markers in humans. A 2016 analysis from the PDP found that 80% of 531 apple samples contained residues of this chemical at 0.002-3.8 ppm, which is below the EPA's tolerance level of 10 ppm. Dietary fat, including high PUFA intake, is associated with increased lipid peroxidation resulting in DNA damage (40). Research in animals allows for detailed analyses of the effect of AP on lipid parameters beyond simply measuring lipid levels in plasma. Antioxidant activity, including the scavenging of free radicals, is thought to reduce cell proliferation and induce detoxification enzymes and apoptosis. Oxford University Press is a department of the University of Oxford. In Finland, apples and onions are main sources of dietary flavonoids, while in the Netherlands apples rank third behind tea and onions as top sources of flavonoids [14,15]. Metastasis pattern and prognosis in children with neuroblastoma. Early work suggested a potential association between AP intake and reduced risk of coronary artery disease, lung cancer, asthma, and diabetes. Dianne A. Hyson, A Comprehensive Review of Apples and Apple Components and Their Relationship to Human Health, Advances in Nutrition, Volume 2, Issue 5, September 2011, Pages 408420, https://doi.org/10.3945/an.111.000513. Schaefer et al. Given the increasing incidence of these 2 conditions, further study of the effect of AP on osteoporosis and diabetes is important to consider. A similar pattern of beneficial association was present when the groups were stratified by age, energy intake, vegetable consumption, smoking, and BMI. A group of Finnish women consuming >71 g of apple/d experienced a 43% reduction in coronary mortality compared to women who did not eat apples. One recent investigation focused on isolating and identifying bioactive compounds in apple peel associated with antiproliferative activity (32). Hydrogen peroxide, aqueous solution 30%. In a combined investigation using cell and animal models to mimic nonsteroidal antiinflammatory drug injury, cultured gastric epithelial cells (MKN 28 from a human gastric tubular adenocarcinoma) were exposed to oxidative stress via 2- to 3-h exposure to xanthine oxidase and live rats were subjected to indomethacin, each with or without treatment with phenolic-rich extracts of freeze-dried apple (flesh only). The grade is characterized by: Very high corrosion resistance in strong acids. The authors proposed that the weight loss was due in part to the significant decrease in energy density of the diet due to the addition of apples compared to the oat cookies in spite of the comparable fiber content of the two. However, detailed analysis of the nutrient content and antioxidant properties of the seeds and pulp has not yet been reported. Colorectal or colon cancer, the 4th most common cancer and the 3rd most common cause of death in Western society (16), has been the focus of many investigations. Dietary antioxidants are of interest, because they add to the endogenous potential of the body to scavenge ROS and nitrogen-free radicals and directly counteract lipid peroxidation reactions. Fermented apple juice extract had an antiproliferative effect in both cell lines, particularly in the LT97 cells, suggesting a greater effect on precancerous than cancer cells. selenium. Alloy 28 is a high-alloy multi-purpose austenitic stainless steel for service in highly corrosive conditions. Furthermore, AP are available on a year-round basis and the per capita utilization of apples and AP in the United States has been on the rise over the past several years (10). Unprocessed pomace containing 61% of dietary fiber (DF) and 0.23% of polyphenols (PP) and ethanol- or ethanol/acetone-extracted pomaces containing 66% DF and 0.10% PP and 67% DF and 0.01% PP, respectively, were subjected to a 4 week study in rats. There has been a growing appreciation and understanding of the link between fruit and vegetable consumption and improved health. The current report focused on studies published since the last review of AP and health in 2004 (1). Several ranking studies have been completed and the pros and cons of chemical methods used to assess in vitro antioxidant activity of fruits and vegetables have been debated and will not be reviewed here. Abstract Suberized cell walls formed as barriers at Using modern analytical techniques, a comprehensive study of the chemical composition of fruits from apple cultivars grown in Western Norway during 2019 and 2020 was done. Hydrofluoric acid, 40%. The widespread and growing intake of apples and apple juice/products and their rich phytochemical profile suggest their important potential to affect the health of the populations consuming them. Treating the cells with apple juice extract increased the expression of several genes, including phase 2 enzymes associated with chemoprevention (sulfotransferases and glutathione S-transferases). An intriguing report published in 2007 involved studying the association between maternal diet and the presence of asthma and respiratory symptoms in offspring 5 y later (56). The findings of these investigators and many others suggest that the whole is greater than the sum of the parts in terms of a protective effect of AP on cancer. Further examination demonstrated that apple juice intake reduced a compensatory increase in the endogenous antioxidant glutathione, suggesting that the antioxidant activity of apple juice accounts in part for the observed protective effects in animals subject to dietary and genetic oxidative stress and a potential neuroprotective effect of AP under these conditions (59). The reduction in NF-B activity observed in these studies aligns with the suppression of cell proliferation by AP reported in many investigations. Hydrogen sulphide saturated. A small study of absorption in ileostomy patients showed that 66.9100% of ingested apple phenolics were absorbed or metabolized in the small intestine, implying that a range of 033% might reach the colon (25). The apple extracts and curcumin, but not other phytochemicals, significantly reduced the TNF-induced activation of NF-B by reducing proteasome activity, a known target in regulation of NF-B. The type of molecule that produces an odor is called an aroma compound or an odorant. Investigations with this model have provided important clues that mechanisms of neuroprotection may extend beyond antioxidant effects. It was found that apple consumption increased antioxidant enzymes, including SOD and glutathione peroxidase, in erythrocytes and overall antioxidant potential in plasma. Data were based on FFQ (including interviews) of dietary intake in the 2 y prior to diagnosis. In addition to clinical data, recent animal feeding and in vitro studies have aimed to examine the potential protective link between AP and cancer. In conclusion, the data related to AP and disease risk reduction are provocative and varied. Colonic microflora metabolize ingested polyphenols. It is not known whether this is important under physiologic conditions, but it is an interesting mechanism by which AP might be related to glucose control in diabetes. Search for other works by this author on: Apple phytochemicals and their health benefits, Effects of dietary flavonoids on apoptotic pathways related to cancer chemoprevention. CardboardChampion 3 yr. ago. 42. Pigs were fed a prooxidant diet, high in PUFA (linseed oil) with or without concurrent fresh apples for 22 d and then tested for several markers of oxidative damage. Review of 93 intervention studies. [4] Processing [ edit] Apples are loaded onto a processing belt where they are crushed, pressed, and the juice separated. The longer exposure time suggests that apple extracts target signaling elements upstream of PKC and not PKC specifically. (23) recently reported that PKC activity was reduced by 50% in HT29 cells after 24-h exposure to apple extracts at a relatively high concentration (403 g/mL). Composition of apple wastes used as raw materials; comparison of the elemental composition of the materials from the as-received apple waste and from the residue kept in air for 8 days; TGA and DTA curves for the pyrolysis of apple pomace under N 2 at 20 C min -1 . 2.5. Women in the highest quartile of apple intake compared to the lowest quartile had a significantly lower incidence of asthma. Although apples and citrus were collectively associated with reduced risk of diagnosed asthma, adjustment for citrus eliminated the significance of the effect of apples. Other enzymes related to cancer etiology are also favorably affected by AP (24). (5965) have provided novel data on the potential of apple juice concentrate to modulate processes associated with the risk of Alzheimer's disease. Apple also decreased the presence of ROS generated by hydrogen peroxide exposure in lymphocytes isolated from each participant at 3 and 6 h after the apple test meal. The observations that AP intake might be associated with reduced risk of cancer have led to an expanded field of animal and in vitro work with cell models that mimic phases in the initiation, promotion, and progression of cancer.
