Berries such as food antioxidants Nature's # 1
Black berries like blueberries and cranberries are increasingly recognized in the opinion as icons of public health. Not only for its nutritional content of vitamins, minerals, amino acids, protein and dietary fiber, berries are as synonyms for the health benefits of antioxidants.
Antioxidants are an important nutrient category thought to be equipped with the largest orchard and vegetable health. Antioxidants are substances synthesized in the body or obtained by chemical plant foods that can prevent or slow oxidative stress in the cells of our body. More than 60 diseases, including cancer, diabetes, inflammation, neurological diseases and cardio-vascular related to oxidative stress may be relieved by dietary antioxidants.
Scientists believe that antioxidants plants produce chemicals to protect the regenerative capacity of plants against the damaging effects of constant exposure to sunlight, ultraviolet radiation, infection, parasites, injuries and oxygen radicals produced during photosynthesis. These antioxidants are found in highest concentration in the fruit skin (or skin) and seeds.
Antioxidant phytochemicals such as anthocyanins, blueberries, and blue pigments contribute to skin the smell of berries. This regeneration plays a useful role in attracting pollinating insects and birds eat the fruit and then disperse the seeds in their droppings.
Plants have also an antioxidant in protecting the skin against UV radiation, the photo-oxidizing agents and viral or bacterial pathogens. They are benefits that can be transmitted to animals and humans who eat the berries.
Oxidative Stress and the "Pigment Power"
Without protective antioxidants such as anthocyanin pigments in the skin of the bay, the species of reactive oxygen (ROS) are created during normal photosynthesis leading to oxidative damage. These injuries affect proteins, lipids and nucleic acids and may cause disturbances in the transcription of genes and even cause programmed cell death (a process that scientists call "apoptosis", Poh-toe eh SIS) in fruits or seeds. Some botanists and food chemists refer to the benefit of protection as "coloring power" must be obtained by feeding the man. We acquired this transfer of protection by eating fruits, vegetables and animals with rich color pigments. Blackberries are an excellent source of these pigments.
Inside berry color that we can find many members of the group of pigments called "phenolic". Each member provides antioxidants, color, aroma, flavor and quality. What follows is just a sample of the thousands of edible plants, phenolic compounds. A species Berry may contain dozens of antioxidant pigments. Each of the following berries is a rich source of anthocyanins, some of which are listed in medical science Food and showed evidence of health benefits preliminary.
Here is a list of antioxidants present in grain following:
ripe: gallic acid
or Black raspberries: ferulic acid
or blueberries: anthocyanins, chlorogenic acid, peonidin
O Cranberries: proanthocyanidins Catechins, Quercetin
O Elderberries: myricetin
or red raspberries: ellagitannins, procyanidins
or red grapes: resveratrol, the proanthocyanidins (seed), catechins,
or strawberries: ellagic acid
ROS – Radical oxygen species
When human cells use oxygen they naturally produce ROS as byproducts of normal metabolism. This can lead to damage in normal cells, if the balances were absent fighting in the environment in and around the cells. ROS are also called oxygen free radicals or elements reagents so that they are "free" to interact with numerous cells and chemicals in the body, often in a manner that is harmful.
The synthetic antioxidants internally or introduced into the record our diet as sponges neutralize or "scavengers" of ROS. By donating electrons wanted by free radicals, antioxidants help counteract the molecules absorb, deactivate the prevention or repair damage caused by ROS.
However, when the checks and balances are ineffective, perhaps due to a poor diet or high antioxidants in food during the decline of body functions to disease or aging, ROS randomly dispersed in a gradient concentration from its point of formation. There, if left unchecked by antioxidants, which can cause cell damage and neighboring cells, which may contribute to disease and aging. This is an important theories of how Alzheimer's destroys gradually neurons.
Oxidative stress and diet "Therapy"
Most diseases are initiated and perpetuated some measured by ROS and antioxidants in sufficient quantities of domestic and diet. These are the underlying conditions of "oxidative stress", which in May explain an important part of aging.
If they are chronic, oxidative stress can lead to an increased risk of developing the following diseases:
• Cancer
• Cardio-vascular disorders and inflammatory
• Diabetes
• neuronal degeneration (eg, Alzheimer's and Parkinson's disease)
• Macular degeneration causes vision loss and a general deterioration aging
• Chronic diseases
Measurement of force Antioxidant: ORAC
The term ORAC, the "absorption capacity oxygen radicals, is a form of digital representation ability of antioxidants in fruits and other foods. When antioxidants are present in food, their collective strength can be measured in the test tube assay called ORAC.
Recently, scientists working with the Department Agriculture SU has published a database of ORAC values.
Black berries, especially wild and cultivated blueberries, blackberries and blueberries, are highlighted with the highest ORAC values between about 25 fruits tested. Their values were within the range of about 7,000-13,000 units ORAC per cup or 250 ml serving.
Preliminary guidelines recommend North America at least 5,000 ORAC units per day for feeding adults. Doubling that number would be not only safe for reserves of antioxidants, but also provide antioxidants to provide macro and micro nutrients Many essential. And more importantly, it would be to eat!
The ORAC test is likely to win public acceptance as a standard measure that allows comparisons of freshness and the ability of antioxidants in various foods. This rule will facilitate the selection of foods ORAC and relate to protection of the antioxidant potential capacity of health. For example, scientific evidence and an inverse correlation between dietary antioxidants and the incidence of certain types of cancer (U.S. National Cancer Institute).
Antioxidant Berries
Wild Blueberry (Vaccinium angustifolium).
Wild lowbush blueberries have anti-oxidant strength of nearly 50% more than their cousins growing – corymbosum blueberries – which is so popular in supermarkets. Wild blueberries score high in ORAC more frequent (but not all) of berries, with about 13,000 ORAC units per cup or 250 ml. Over the last 10 years, the emphasis food scientists in the health properties of wild blueberry has shown convincing history of a rich elements nutrients and variety of potential benefits to health, including:
• On the health of the urinary tract (identical in strength of blueberries)
• Inhibition cancer development
• cardiovascular protection
• Mental alertness
• Vision Support
Blackberry (Rubus ursinus)
The dark juicy BlackBerry has a rich taste and nutrients. Confirming the idea that black berries are correlated with antioxidant activity more powerful, science has recently shown that the berries are one of the densest concentrations and wider diversity of phenolic compounds in the plant world. Blackberry is about 8000 ORAC units per cup or 250 ml.
Black raspberry (Rubus occidentalis)
"Blackcap" power are little known wealth in antioxidants and exceptional flavor. Black raspberry isolates shown in laboratory tests to starve tumor cells specifically to prevent tumor growth of new blood vessels. Overall, a powerful antioxidant berries such as wild blueberries (ORAC> 15,000 per cup or 250 ml) warblers contain a set of tools flavors and nutrients.
Cranberry (Vaccinium macrocarpon)
The North American cranberry has become famous for its popular juice. Although known for their anti-adhesion, which inhibit bacterial infections in the urinary tract, cranberry extract has been shown anticancer and cardioprotective effects in laboratory studies. These results are mainly produced by the abundance of blueberries antioxidant phenolic compounds are also a promising agent for blood, brain and visual health.
Elderberry (Sambucus nigra)
Another Berry phenolic-rich taste great dark, elderberry has been associated with many potential health benefits already mentioned. Emphasis was placed on the laboratory tests for its beneficial anti-inflammatory and urinary tract. The elder is also promising for anti-bacterial and anti-viral which may offer protection against virulent pathogens such as Salmonella, E. coli, H. pylori, and Staphylococcus.
Red raspberry (Rubus idaeus)
Red Raspberries are very appreciated its subtle flavor, but also a wonderful store of antioxidant phytochemicals, including one called ellagic acid. One of its other components, a ketone, has been demonstrated in recent laboratory studies to stimulate fat metabolism, which makes animals experimental to lose significant weight.
Red grape (Vitis Vitus)
The red grape is prized for its popular taste and familiar different number of phenolic compounds that are mainly skin and seeds. Particularly rich in phenolic called resveratrol, a powerful antioxidant, red grapes are associated with a possible beneficial effect on:
• Alzheimer's Disease
• Heart disease
• Cancer
• Osteoarthritis
• Other disorders of aging
Strawberry (Fragaria vesca)
Containing large amounts of antioxidants phenolic constituents of strawberry anti May is particularly important that the natural blood thinner, fungal agents and inhibitors of oxidation in cells effects of chronic stress.
Other antioxidants
Other phenolic antioxidants mentioned in current public media are the following:
• Apigenin
• P-coumarin
• Kaempferol
• caffeic acid
• hydroxycinnamic acid
• Tannic acid
• salicylic acid (similar to aspirin)
These pigments chemical products belong to the subclass of flavonoids in the family of super-phenolic resins are among black berries.
Color-rich plant foods bays offer a way delicious and nutritious food to maintain a high intake of antioxidants. Eat color! ORAC Profit! Live Well!

I have occasional pain in the left breast. In times like liquid movement in the chest.?
I have 35 men. Very often, I am having some pain in my chest, near the center left. Sometimes it feels like one fluid motion inside my chest. 2m ago my stress tests cardiologist perfomed on me, and ultrasound images of various types of X-ray around my chest. End of me says it's healthy for the heart as triglycerides 350. 2 years I was diagnosed there in an emergency to 4.6 toponin, diagnosed as having heart disease and has received several doses of nitro. 3 tests later that night were: 0.01 toponin and restoration, "said 1st event could have been a laboratory error and discharged me after a stress test. I am very confused and would appreciate answers. Thank you in advance.
Its symptoms are very characteristic and can not assess the situation. I suggest you consult your cardiologist as soon as possible to assess the status and treatment. Do not worry. Please attend to priority.
