Many of them never heard the term Free Radicals and what is the relation with them and Oranges, lets talk about the Free radicals first.
An uncharged molecule (typically highly reactive and short-lived) having an unpaired valency electron…got it ? alrighty, it is a typical chemistry definition of free radicals only Einstein type people can understand, in simple word, Free radicals are created by oxidation. In excess they will accelerate your aging and lead to all sorts of negative health problems.
They are simple molecules with an electron missing. In an effort to become ‘whole’ again they seek out other chemical structures in our bodies from where they can steal an electron.
After they ‘acquire’ an electron the chemical structure/tissue from where they ‘stole’ that electron is left seriously damaged!
Free radicals in small and controlled quantities are OK and indeed are helpful in everyday metabolism and they take part in normal reactions in the body. The problems start when the production of these free radicals increases and then get out of control.
Oxidation is unavoidable! So long as we breathe oxygen there will be oxidation in our body and thus the creation of free radicals will always continue!
In an ideal world with no pollution, perfect diet and no stress the level of free radical activity would be ‘normal’ and they would not be a serious problem and we would live to a ripe old age as the Hunza’s and other isolated groups of people used to.
BUT…that is not the case!
Instead, we are subjected to air pollution, second hand smoke, lack of nutrients in our diet, artificial radiation, toxins in food and we are inadvertently exposed to a wide range of toxic chemicals in our daily lives. (Even in our furniture)! Collectively this is bad news for those of us living in the ‘civilized’ world.
There are three ways to minimize the damage from free radicals:
1. Environmentally through avoiding pollution, radiation etc. Impossible if you live in a ‘civilized’ populated area.
2. Neutralizing of free radicals by anti-oxidants
3. Increasing the elimination of cells damaged by free radicals.
So, how do antioxidants ‘neutralize’ free radicals?
In simple terms they voluntarily give one of their electrons to a free radical molecule! Simple !
Oranges are the pure, natural occurring Antioxidants
Juicy and sweet and renowned for its concentration of vitamin C, oranges make the perfect snack and add a special tang to many recipes; it is no wonder that they are one of the most popular fruits in the world. Oranges are generally available from winter through summer with seasonal variations depending on the variety.
Oranges are round citrus fruits with finely-textured skins that are, of course, orange in color just like their pulpy flesh; the skin can vary in thickness from very thin to very thick. Oranges usually range from approximately two to three inches in diameter.
Oranges’ Healing Phytonutrients
In recent research studies, the healing properties of oranges have been associated with a wide variety of phytonutrient compounds. These phytonutrients include citrus flavanones(types of flavonoids that include the molecules hesperetin and naringenin), anthocyanins, hydroxycinnamic acids, and a variety of polyphenols. When these phytonutrients are studied in combination with oranges—vitamin C, the significant antioxidant properties of this fruit are understandable.
But it is yet another flavanone in oranges, the herperidin molecule, which has been singled out in phytonutrient research on oranges. Arguably, the most important flavanone in oranges, herperidin has been shown to lower high blood pressure as well as cholesterol in animal studies, and to have strong anti-inflammatory properties. Importantly, most of this phytonutrient is found in the peel and inner white pulp of the orange, rather than in its liquid orange center, so this beneficial compound is too often removed by the processing of oranges into juice.
A Glass of Orange Juice More Protective than Vitamin C Alone
Consuming vitamin C supplements does not provide the same protective benefits as drinking a glass of orange juice, shows research by Italian researchers in the Division of Human Nutrition at the University of Milan, Italy (Guarnieri S, Riso P, et al., British Journal of Nutrition).
Seven healthy test subjects were given each of three drinks, two weeks apart: blood-orange juice containing 150 milligrams of vitamin C, fortified water containing 150 milligrams of vitamin C, and a sugar and water solution containing no vitamin C. Blood samples were collected immediately before the drink was consumed, then every hour for 8 hours, and finally 24 hours after consumption of each drink.
Blood samples were exposed to hydrogen peroxide, and free radical damage to DNA was evaluated at 3 and 24 hours. Only when orange juice was consumed was any protective effect seen. After drinking orange juice, DNA damage was 18% less after 3 hours, and 16% less after 24 hours. No protection against DNA damage was seen after consumption of the vitamin C fortified drink or the sugar drink.
While another study, which looked at much larger quantities of vitamin C, did show a protective effect from the vitamin alone, this research indicates that not only is the protection afforded by fruit more complex, but smaller amounts of nutrients like vitamin C are all that are needed for benefit.
Said lead researcher, Serena Guarnieri, “It appears that vitamin C is not the only chemical responsible for antioxidant protection.” In oranges, vitamin C is part of a matrix involving many beneficial phytochemicals (for example, cyanidin-3-glucoside, flavanones and carotenoids).”But how they are interacting is still anyone’s guess,” she added. Fortunately, we don’t have to wait until scientists figure this out to receive oranges’ DNA-protective benefits. Practical Tip: For the best DNA protection, skip the vitamin C—fortified bottled drinks and enjoy a glass of real (preferably organic as organic foods have been shown to contain higher amounts of phytonutrients), freshly squeezed orange juice—or simply eat an orange!
Owing to the multitude of vitamin C’s health benefits, it is not surprising that research has shown that consumption of vegetables and fruits high in this nutrient is associated with a reduced risk of death from all causes including heart disease, stroke and cancer.
