When the body turns food into energy one of the inevitable by products are free radicals, which are capable of damaging genetic material and cells. Free radicals can alter a substances structure and function by stealing electrons if available. The body has natural defenses against these free radicals which are called antioxidants; they work by giving electrons to the free radicals without then having the antioxidants search for electrons. There are many different antioxidants some of the more common ones include beta carotene, Vitamin C, and Vitamin E.
There are many claims out there that taking antioxidant supplements or increasing our intake of foods containing antioxidants will prevent heart disease, cancer, and other conditions. In Vitamin E trials done on people who had been diagnosed with coronary disease showed no benefit. One study showed that people who take antioxidant supplements have an increased risk of death and not opposite which has been the idea behind antioxidants for many years. Take into consideration that these studies were short in duration and many of the test subjects already had an existing disease. While we may not know much about antioxidants and whether or not they are beneficial or harmful towards a person’s overall health, it is important to keep in mind that living a healthy lifestyle and eating healthy whole fruits, vegetables, and grains can help prevent many diseases.

Clinical Benefit of Dark Chocolate

...dark chocolate production from cacao beans in regards to its antioxidant flavonols content with correlation to positive health benefits. Fermentation is required to break down the bitter taste of cacao beans in its original form, but lowers the beneficial antioxidant content within the cacao beans by changing the concentrations and composition of procyanidins and flavan-3-ols. After fermentation, the beans are roasted to produce a more favorable taste through Maillard and caramelization reactions of sugars, amino acids, and peptide oligomers. The subsequent step of milling cacao beans into fragments allow flavonoids to interact with other molecules such as theobromine, caffine, and l-leucine which determines both flavor and antioxidant activity in chocolate. Other antioxidant properties have been linked to polyphenols, catechin, and epicatechin in dark chocolate made from cacao beans in addition to flavonoids. Conching is the process after milling, it is a multi-day heat treatment that grinds the chocolate to improve flavor and decrease free acids and volatile by-products. An alternative to conching is the dutching method, it neutralizes acetic acids in cacao. Dutching as opposed to the more gentle conching technique, significantly reduces antioxidant flavonoids content in dark chocolate. Theobromine and caffeine in dark chocolate are proven to have mild vasodilative and diuretic effects on the body. Antioxidants in dark chocolate are bioavailable in the body. After......

Selenium in Egg

...times of greatest need, such as during times of stress. • Only a small amount of Inorganic Selenium finds its way into body protein. • Organic Selenium is retained by our body in useful form. • Inorganic Selenium is poorly retained. Why Does Our Body Need Selenium? Selenium is a component of several antioxidant proteins such as glutathione peroxidase, superoxide dismutase and catalase. Antioxidants neutralize the toxic by-products of oxygen metabolism. These by-products are known as free radicals which can cause damage to cellular components including DNA. Antioxidants are essential to human health as it helps protect against environmental carcinogens and cardiovascular disease, protects our skin from solar ray damages and may be important in fighting the effects of Alzheimer’s and other age-related illnesses. Glutathione Peroxidase (GSH-Px): Each molecule of gluthathione peroxide contains four atoms of selenium. Thus selenium is a key component of the body's defence against the degenerative effects of age and exposure to toxic free radicals. Superoxide Dismutase: An enzyme that destroys the superoxide radical Catalase: An enzyme that produces Vitamin E, a general antioxidant. Why Does Our Diet Lack Selenium? The selenium content in food is becoming a health issue as the average levels of selenium in our diets have fallen and is well below the amounts recommended for optimum health. The lower availability of selenium in our diets can be attributed to low soil......

These are the agents, which scavenge free radicals otherwise reactive oxygen species and prevent the damage caused by them. Free radicals have been associated with pathogenesis of various disorders like cancer, diabetes, cardiovascular diseases, autoimmune diseases, neurodegenerative disorders and are implicated in aging. Several antioxidants like SOD, CAT, epigallocatechin-3-O-gallate, lycopene, ellagic acid, coenzyme Q10, indole-3-carbinol, genistein, quercetin, vitamin C and vitamin E have been found to be pharmacologically active as prophylactic and therapeutic agents for above mentioned diseases. Antioxidants are part of diet but their bioavailability through dietary supplementation depends on several factors. This major drawback of dietary agents may be due to one or many of the several factors like poor solubility, inefficient permeability, instability due to storage of food, first pass effect and GI degradation.......

Antioxidants

...Antioxidant From Wikipedia, the free encyclopedia Jump to: navigation, search An antioxidant is a molecule capable of slowing or preventing the oxidation of other molecules. Oxidation is a chemical reaction that transfers electrons from a substance to an oxidizing agent. Oxidation reactions can produce free radicals, which start chain reactions that damage cells). Antioxidants terminate these chain reactions by removing free radical intermediates, and inhibit other oxidation reactions by being oxidized themselves. As a result, antioxidants are often reducing agents such as thiols, ascorbic acid or polyphenols.[1] Although oxidation reactions are crucial for life, they can also be damaging; hence, plants and animals maintain complex systems of multiple types of antioxidants, such as glutathione, vitamin C, and vitamin E as well as enzymes such as catalase, superoxide dismutase and various peroxidases. Low levels of antioxidants, or inhibition of the antioxidant enzymes, cause oxidative stress and may damage or kill cells. As oxidative stress might be an important part of many human diseases, the use of antioxidants in pharmacology is intensively studied, particularly as treatments for stroke and neurodegenerative diseases. However, it is unknown whether oxidative stress is the cause or the consequence of disease. Antioxidants are also widely used as ingredients in dietary supplements in the hope of maintaining health and preventing diseases such as......

Benefits of Consuming Increased Amounts of Fruit and Vegetables

...Results were consistent with each other and revealed that fruits and vegetables are rich in dietary antioxidants. Increasing intakes of dietary antioxidants will help to reduce oxidative damage caused by free radicals and provide protection against the progression of a number of chronic diseases. Diseases such as cancer, stroke, dementia and others can be minimized by consuming increased amounts of fruits and vegetables. Although consuming adequate amounts of fruits and vegetables reduces the risk of developing chronic diseases, it is widely recognized that young adults’ intakes are currently well below the Department of Health’s recommendation of five portions a day, with men consuming even less than women. Introduction The advantages of consuming a reasonable amount of fruits and vegetables each day are enormous. Fruits and vegetables are rich in antioxidants; these are substances that protect body cells from oxygen free radicals which cause oxidation (cell damage) that may lead to health problems, such as cancer, artery and heart disease. Free radicals are created when the body burns oxygen which it needs to function. Good sources of antioxidants vitamins are foods containing beta carotene and vitamins C and E. Fruits such as oranges, bananas, strawberries, citrus fruits and vegetables such as cabbage, okra, tomatoes, carrots and green leafy vegetables are good sources of antioxidants. In developed countries, the percentage of subjects aged 60 years and older will......

Antioxidants, Bone Health, and Metabolism in Body Building

...Antioxidants, Bone Health, and Metabolic Process in Bodybuilding Antioxidants are molecules that inhibit the oxidation of other molecules. Oxidation is a chemical reaction that transfers electrons and hydrogen from a substance to an oxidizing agent. Oxidation reactions can produce free radicals and in turn, these radicals can start negative chain reactions. When these chain reactions occur in cells they can cause damage to the cell’s DNA that in turn causes muscle, joint, and tendon damage and inflammation. Antioxidants terminate these chain reactions by removing free radical intermediates, and inhibit other oxidation reactions. Antioxidants such as vitamin C and E can play an important role in reducing inflammation, fatigue, tissue damage, and both prevent and treat injuries. This can play a major role when trying to gain muscle mass due to the fact that your muscles break down when working out. Antioxidants are a vital supplement for athletes as well as body builders. When you exercise heavily in any form, your body actually produces free radicals because your energy systems and metabolism are working at such a high capacity. Taking antioxidant supplements daily can reduce the chances of these free radicals harming your cell production and tissue growth and repair. One of the most important antioxidants that athletes as well as the general public should consume daily is Vitamin C. Your body uses large amounts of vitamin C to fight off infections, colds, and disease and......

Study of the Preservative Effect of a Blend of Tamarindus Indica and Ziziphus Abyssinica Extracts in Extending the Shelf- Life of Meat Balls

... THE STUDY OF THE PRESERVATIVE EFFECT OF A BLEND OF Tamarindus indica and Ziziphus abyssinica EXTRACTS IN EXTENDING THE SHELF- LIFE OF MEAT BALLS ABSTRACT The study is aimed at finding out if combining the two herbs would result in a more effective preservative than when each herb is used independently.Preservation using natural products is associated with the presence of antioxidants,antimicrobial,antifungal or dehydrating properties. Fresh meatballs are made from meats that have not been previously cured,they are made from ground meat,either pork,beef or veal. Meatballs are however susceptible to microbial spoilage and auto-oxidation. The artificial chemical preservatives used in meatball preservation.eg sodium metabisulphite may be replaced by natural extracts such as Tamarind and Ziziphus extracts which have both antimicrobial and anti-oxidant properties. The extracts will be obtained from Tamarind andZiziphusseeds.The seeds will be dried and ground into powder followed by liquid/liquid extraction. The extraction was carried out by 400ml ethyl acetate and water for 100grams from each sample. The fresh meatballs will be processed in the JKUAT meat workshop using the correct recipe. Fresh meatballs batch with no preservative will act as the control. Another batch with sodium metabisulphite and finally with the seed extracts. The processed fresh meatballs will be stored at 40c and at 250c and the samples analyzed within a staggered period of 4 weeks for......

Green Ox

...Green Ox – Executive summary Palmer Jackson has a few issues to address regarding Green Ox. The first issue is which segment to target. Other issues include how the product would be positioned in the minds of its potential consumers, how the product would be priced to the retailer as well as many flavors should be introduced. All these issues need to be dealt with before they can market the product successfully. Since this is a product that crosses over two markets, there are several factors that need to be considered. One factor to consider is that due to the added cost of antioxidants, Green Ox will be overall more expensive to produce than competitor sports drink ($.20 compared to $.15). In addition, getting onto the grocery shelves may be a factor to consider because these types of stores are often hesitant to welcome smaller players due to a big demand fluctuation that seems to be present. On the other hand, grocery retailers view the sports-drink category as more important than club stores due to the fact that club stores trend to ignore products until it has a successful track record. Another factor to consider is that most sales would be four-packs instead of single bottles. When it comes to the flavors, studies showed the only 30% of potential customers were more loyal to flavor than brand. In addition, each additional flavor would require $10 million to introduce. Other factors to consider include which market shops at what type of store and how that might......

Vitamin C: Can It Help to Prevent Cardiovascular Disease?

...are excellent sources of vitamin C, which is a water soluble vitamin. Fruits with the highest sources of vitamin C include cantaloupe, citrus fruits and juices, such as orange and grapefruit kiwi fruit mango and papaya among others, whereas vegetables that have vitamin C comprise broccoli, cauliflower, green and red bell peppers, and brussels sprout 2. Vitamin C – as an antioxidant – functions by helping to neutralize the action of free radicals, which are substances that damage DNA and cells or tissue 5. With time, the build up of free radicals is known to accelerate the aging process as well as the development of chronic diseases such as cardiovascular disease, cancer and arthritis 2. This paper aims to give a brief overview of the impact of vitamin C on cardiovascular disease. The case for vitamin C in cardiovascular disease Various studies have examined the role of vitamin C in regards to preventing chronic diseases that are triggered by oxidative stress, such as cardiovascular disease; however, reports on such studies are not consistent. For instance, few clinical studies such as the Women's Antioxidant Cardiovascular Study (WACS) reported no significant impact of vitamin C supplementation on the prevention of either primary or secondary cardiovascular disease 3. Furthermore, in a longitudinal study that comprised 8,171 women, aged 40 years or older with a history of cardiovascular disease, it was reported that supplementation with 500 mg/day vitamin C over a......

Neuroprotective Effect of Tocotrienol-Rich Fraction and α-Tocopherol of Vitamin E Against Glutamate Toxicity in Neuronal Cells and Astrocytes

...Vitamin E is a fat-soluble antioxidant consisting of tocopherol and tocotrienol. The tocotrienol-rich fraction (TRF) palm oil extract comprises 25% α-tocopherol (α-TCP) and 75% tocotrienols. TRF has been shown to possess potent antioxidant, anti-inflammatory, anti-cancer, neuroprotective, and cholesterol-lowering activities. Glutamate is the main excitatory amino acid neurotransmitter in mammalian central nervous systems; it can be excitotoxic and has been suggested to play a key role in neurodegenerative disorders such as Parkinson’s and Alzheimer’s disease. In this study, the effects of vitamin E when supplemented before (pre-treatment) and after (post-treatment) glutamate insult were elucidated in neuronal and astrocyte cell lines. The neuroprotective effect of TRF and α-TCP were investigated. Glutamate-mediated cytotoxicity was diminished by pre- and post-treatment of TRF and α-TCP. Vitamin E acted as a potent antioxidant agent in recovering mitochondrial injury from elevated oxidative stress, and cells exhibited better survival following glutamate toxicity. Quantitative morphological studies were also conducted via an apoptosis detection kit using flow cytometric analysis. Pre- and post-treatment with TRF and α-TCP led to better survival and lower cell death rates following glutamate neurotoxicity. The flow cytometry morphological findings were validated by scanning electron microscopy analysis. Cell cycle analysis was also performed using an RNAse-propidium iodide assay...

Antioxidants

...1. What did you learned about the role of antioxidants in our body? Antioxidants are intimately involved in the prevention of cellular damage. Antioxidants help protect the body from the free radicals before they can cause any damage. So, they also play a role in preventing some chronic diseases that can be caused by free radicals as well. 2. How do free radicals affect our health? Free radicals are not equally paired in electrons and they bind to substances that can potentially cause a reaction in our normal body cells. These changes can occur in DNA which can cause our cells to function poorly or not function at all. 2. What are some foods that you like and would be willing to incorporate in your diet as a result of your readings? Im interested in incorporating vitamin A into my diet since I have vision problems. I found that I already eat most of these foods, but not as much as I used too. Foods that include vitamin A are: carrots, dark leafy greens, romaine lettuce, tuna fish, and melon. 4. Now write a 300 word short essay about ONE specific antioxidants (herb, mineral, or vitamin), make sure to choose one that interests you. Many of us have or had grandmas that took care of our sicknesses with a tea or an herb blend, research that herb for healing properties (you may use the sites I gave you or choose another credible source).

The Correlation Between Antioxidants, Diet, and Cancer

...of fruits and vegetables, which contain antioxidants and phytonutrients. Background Cancer is a collective term describing uninhibited cell propagation in various parts of the human body [1]. This process is called carcinogenesis (literally means “cancer creation”). Once propagated, the cancer can spread and cause death in a timely manner. Cancer occurs via mutations in the genetic code that can occur in a variety of cells in the human body. Mutations of this sort are believed to be the result of oxidative stress. In the human body oxidative stress occurs when there is a disparity between free radicals and antioxidants, thus compromising the body’s ability to cleanse itself. In fact, one of the more detrimental characteristics of oxidative stress is the production of free radicals. Finding the cause of cancer in any patient is, for the most part, unfeasible as there are a variety of possible causes for various cancers, but it all begins at the cellular level with the ever-presence of free radicals. Presently, there are many known risk factors for carcinogenesis, but perhaps the most influential risk factors are environmental and poor diet [2]. Consider your diet for just a moment; does it consist of natural fruits and vegetables, lean meat, or fish? Does it consist of french fries, pop, potato chips, and the occasional Subway sandwich? If it consists of processed and fast foods; then the diet is lacking vital nutrients and antioxidants, which promote a state of oxidative......
