Can Foods Slow Down Aging?
Studies at the USDA Human Nutrition research centre on aging at Tufts University in Boston suggests that consuming fruits and vegetables with high ORAC values may help slow the aging process in both the body and the brain. Oxygen radical absorption capacity – measures the ability of foods, blood plasma and just about anything to subdue oxygen free radicals in test conditions.
These results have driven theories that the ORAC measure may help define the dietary requirement needed to help prevent tissue damage.
It has been suggested for many years that damage by oxygen free radicals is behind many conditions associated with aging, including cardiovascular disease and cancer. Firm evidence supports the theory that a high intake of fruits and vegetables reduces the risk of cancer and a low intake raises risk. Recent evidence suggests that reduced brain function associated with aging and other disorders like Alzheimer’s may be due to increased vulnerability to free radicals.
It’s in the Blood
Several laboratories have reported that individual plant derived antioxidants (flavonoids) can be absorbed and are thought to have protective powers. Approximately 4,000 flavonoids have been identified, and constitute a major class of antioxidants and appear to be responsible for the major part of fruit and vegetable power. Scientists have found evidence that food antioxidants are not only absorbed but actually boost the antioxidant power of the blood
A study involving 36 men and women aged 20 to 80 was conducted with the participants doubling their daily fruit and vegetable intake. The average quantity of fruit or vegetable portions was increased from 5 to 10 a day and the relative ORAC daily units calculated. The daily ORAC consumption was raised from 1,670 to between 3,300 and 3,500, approximately double the previous score. Blood analysis indicated a 13 to 15 percent rise in blood plasma ORAC scores. This study supports a preliminary study, which showed a 25 percent rise in serum ORAC after 8 women were given test meals made form high ORAC foods, red wine or vitamin C. Red wine was used as it tests high for ORAC and has been linked to a lower risk of cardiovascular disease.
You are what you Eat
The ORAC values of foods is so broad range that selecting the right foods is vitally important. For example, choosing six foods with lower values could provide less ORAC units than a single food with a high score. Studies have yielded even more support for high ORAC diets. High ORAC diets have been linked to the protection of nerve cells within the brain against effects of aging. Researchers have concluded that motor and memory loss cannot be prevented completely but high ORAC diets help prevention and management of these age related conditions. It is considered that ORAC may become the standard for antioxidant protection.
How is ORAC measured?
Oxygen Radical Absorbance Capacity (ORAC) is a standardized test adopted by the U.S. Department of Agriculture to measure the Total Antioxidant Potency of foods and nutritional supplements. This standardized test was developed by Dr. Guohua Cao, a physician and chemist at the National Institute on Aging in Baltimore, Maryland. It provides us with a very precise way of determining the Free Radical destroying or neutralizing power of a particular food, supplement or compound.
Here's how it works: A sample of antioxidant in the form of food, drink, fruit, nutritional supplement, vitamin, or chemical substance (example, orange juice, carrot, or vitamin E) is put in a test tube to see how well and how long it takes to destroy or neutralize the free radicals. This test or substance is then given an ORAC SCORE that reflects the Power and Speed with which it does its job as an antioxidant. Dr. Cao and Dr. Prior of the Human Nutrition Research Center on Aging at Tufts University have established that their recommended 5,000 ORAC Units Daily help prevent certain age related diseases.
The Right ORAC Source for you
Res-JÜVENTA is produced in Spain through a patented process which uses the whole (pomace) Spanish Blue Grape (Vitis Vinifera), including its pulp, skin, seeds and stems. The result is a
100 % natural organic capsule containing a staggering ORAC count of 4,803 μmol TE/g.
Enough of Science
Ok, what does this mean for the average person?
The latest guidelines from the Food Standards agency (FSA) advises that everyone consumes at least 5 portions (1 portion = 80g) of fruit and vegetable a day.
A High ORAC diet, in an average day, could consist of;
Strawberries (40g) & Kiwi (40g)
Stuffed pepper (80g) followed by a small Orange (80g)
2 servings of vegetables (Broccoli and Cauliflower)
This would yield in a total daily ORAC value of 3,400. But the average daily score for a more “normal” diet would be about 2,000 units. The aim of a high ORAC diet would be to achieve a daily intake of no less than about 5,000 units.
Supplementing a daily diet with a capsule of Res-JÜVENTA will add 4,803 μmol TE/g, thereby ensuring that the recommended ORAC intake is not only achieved, but is considerably enhanced.
While the daily intake of a Res-JÜVENTA will help reach the suggested daily value, we think that it is important to recommend an existing healthy diet which still includes fruits or vegetables. On the other hand, with our busy life style we may not always be able to obtain the required fruit and vegetable intake in any given day, and a daily Res-JÜVENTA will always be readily available to make up for the occasional deficit.
