Oxidative stress, known to play a role in the pathogenesis of most diseases, has been the focus of many new studies to determine the effectiveness of AP in an antioxidant capacity. (5965) have provided novel data on the potential of apple juice concentrate to modulate processes associated with the risk of Alzheimer's disease. Increasingly protective effects were observed in rats fed extract doses equivalent to 1, 3, or 6 apples/d with reductions in tumor incidence of 17, 39, and 44%, respectively. 42. 3. 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. It was shown that extensive isomerization, cleavage, and conjugation of the native polyphenolic compounds occurred. One of the most common pesticides used on apples after harvest is diphenylamine, used to prevent apple scald or browning of the skin that can occur during storage. Favorable effects on antioxidant enzymes in liver including SOD, GSHPx, and general markers of oxidation (hepatic TBARS) were significantly reduced by 4752%. The test meals were adjusted to provide comparable macronutrients. The chemical composition of apples and cider. In a 100 gram (ml) reference amount, it provides 22 calories, with negligible content of micronutrients. a compact disc. Other enzymes related to cancer etiology are also favorably affected by AP (24). However, it is plausible that the low-energy density and fiber content of apples make them effective in weight reduction diets. The in vitro findings align with the results of animal studies, demonstrating that apple extracts modulate the cell cycle, an important mechanistic explanation of the observed effects of AP on mammary tumor inhibition. 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. Are All These Chemicals Found in a Banana? | Snopes.com Apple intake of >31.2 g/d (i.e. 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). The potential of AP phytochemicals to reduce disease risk and improve health has caught the attention of scientists, practitioners, and the lay public. Parents/caregivers reported apple and apple juice intake and health data of over 2600 children aged 511 y. List of Chemicals Dangerous Chemicals in Everyday Products 2. Best. In men, the risk reduction was 19% in the group consuming >54 g compared to no apple intake (34). In the living rats, drinking the apple extract in water for 10 d or 1 h prior to indomethacin-induced injury prevented macroscopic injury and partial microscopic damage by 4045% (75). Approved as a medicinal fruit by the Chinese National Health and Wellness Commission [], hawthorn has higher dietary fiber, pectin, ascorbic acid, minerals, and antioxidant capacity than some common fruits [].Studies have confirmed that hawthorn is rich in amino acids (8 essential amino acids and 3-8 times more amino acids than fruit), protein (17 times . However, detailed analysis of the nutrient content and antioxidant properties of the seeds and pulp has not yet been reported. Several studies demonstrate that AP reduce cell proliferation, alter markers of the cell cycle, increase apoptotic mechanisms, and modulate signal transduction pathways. no attached saccharide residue) may be better taken up by cells and may have higher reactivity/antioxidant capacity. A recent study in hamsters evaluated the effects of adding daily apples and apple juice (pressed from fresh apples) to an atherogenic diet on lipids, oxidative markers, and early aortic lesions (47). Another study examining oxidation in humans involved providing 150 mL of apple juice, prepared from homogenized apple flesh, to 10 healthy young male participants in Japan and testing their blood at periodic intervals using a fluorescent probe (2,7-dichlorofluorescin) as an indicator of ROS formation and oxidative stress (37). The aim of the study was assessing the advantages of dietary supplementation with the above pomaces. The investigators isolated 43 components from an organic extract of apple and tested each for antioxidant/free radical scavenging activity using 5 different in vitro methods. I thank Sue Taylor and Stacie Haaga for their helpful discussion and review. New data have suggested a possible link between AP consumption and reduced risk of diabetes. Add a Comment. 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. 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. Poultry Consumption and Human Health: How Much Is Really Known? Anti-vaxxer vs. chemical composition of an apple : r - Reddit Thus, apples may be potentially important in weight-related disorders. (20) crushed and extracted juice from cider and table apples harvested in Germany to prepare several polyphenolic mixtures, including one extract from apple pomace. More than 4000 flavonoids have been identified and all share a common carbon skeleton structure (C6-C3-C6). Therefore, the main objective of this current study was to determine the chemical composition, nutritional It is thought that lungs are particularly susceptible to oxidative damage due to high and continual exposure to oxygen. Fresh apple intake (26/wk) tended to be protective but was not significant for a dose-response relationship. Chemical compositional characterization of some apple cultivars The reviewed studies do not prove cause and effect and further work remains to be done. Review of 93 intervention studies. In a follow-up to the above study to examine mechanisms, it was found that apple procyanidins have a dual effect of downregulating polyamine biosynthesis concurrent with stimulating the catabolism or breakdown of these compounds (22). It is speculated that environmental and lifestyle factors, such as reduced intake of dietary antioxidants, are contributing to the rise (51). (PDF) Chemical Composition of the Fruits of Several Apple Cultivars Unfermented apple juice extract also had potent antiproliferative effects. The processes associated with aging and amplified in neurodegenerative diseases of aging are complex and not completely understood. aluminum oxide, a white powder that contains a 2:3 ratio of aluminum and oxygen atoms. pandamonium. 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. Does an apple a day keep the oncologist away? There is clearly a need for controlled clinical intervention studies using AP to further examine the potential association between AP and asthma. The loss of bone mass is associated with osteoporosis and is viewed by some as a global epidemic. Hyson, no conflicts of interest. 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. 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. Other reports have indicated that apple intake is associated with reduced risk of asthma and related symptoms. 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]. 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 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 The product can be eaten without fear of pesticides and other harmful impurities. Physical and chemical properties of apple juice and apple juice The men were fed a restrictive, antioxidant-poor diet for 48 h followed by the apple challenge. The concentration of polyphenols is influenced by the plant variety as well as environmental factors, including geographic region, growing season, and storage (3). The chemical composition of an apple includes: water - over 85% of the total mass; proteins and fats - about 1%; carbohydrate compounds - almost 10%; organic acids; alimentary fiber; vitamins: PP, A in the form of beta-carotene, group B, C, E, H, K; The sole author had responsibility for all parts of the manuscript. Evidence relating AP to lung health was summarized in the review of Boyer and Liu (1) and newer studies have built upon earlier work that implicated AP in reduced risk of asthma. 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). A comparison of the lowest quintile of intake (average 43 g/d) compared to the highest 2 quintiles (93.5 and 164.9 g/d, respectively) showed a significant inverse association between combined apple and pear intake and lung cancer in all participants and current smokers. A hospital-based, case-control study published in 2005 included over 6000 participants from various regions in Italy and examined the association between fresh apple intake and risk of cancer (14). 3 comments. Studies aimed at ranking in vitro antioxidant capacity of AP have been inconsistent as have those of other fruits and vegetables; some investigations rank antioxidant capacity as relatively poor, whereas others report good antioxidant activity compared to other fruits (45).
