Radical theory proposes that aging cells to attack free radicals, which ultimately lead to cell damage, disease and aging. In general, free radicals, unstable molecules that have been removed unpaired electron, odd. This molecule has a stable molecule in order to steal “an electron, which attacked the molecule unstable. This destructive chain reaction started, the division of living cells.
Antioxidants such as vitamin E and C, it is believed that the protection of free radicals may be “unstable electrons of free radicals without becoming unstable. Philanthropy Antioxidants prevent damage to the molecular and cellular tissue.
You have probably the oxidation of free radicals often heard as a grating. Antioxidant protection against oxidation, for example.
Lesson: a diet rich in fruits and vegetables?
ORAC has quickly become a popular method of assessment of the main antioxidant capacity of foods. Since there is no industry standard ORAC values are often poor or too difficult to encourage a specific supplement.
ORAC values are marketed as micromole Trolox equivalent (TE) device expression. Trolox is an analogue of vitamin E used in the standard.
Units are confusing for the consumer. The values are expressed as umol TE per gram. But very often you see the results of 100 g or a / l or more confusion, a single dose.
So you can have the same dishes with ORAC values of 1930 and 3000-5700. You have to be careful to determine the units of measurement. In addition, various foods, it seems that a higher value depending on whether the comparison of dry or wet weight. Click here for examples of the reported values range of dishes.
ORAC Research
A few investigators are Ronald L. Prior and Guohua (Howard) Cao, for the for James Joseph (neurologist worked) and Barbara Hale Shukitt (psychological behavior) at Tufts University Jean Mayer USDA Human Nutrition Research Center in Boston to raise awareness Anti Oxidation is a means to increase activity. In fact, Cao ORAC measure developed, while the National Institute of Aging. See: “Does the aging of the forest products? Drs Before Cao and a significant increase in plasma ORAC values of the participants, their daily fruit increased and vegetable consumption is 10 servings. The average dose, the group pre-test a 1670 ORAC units per day. During the study, consumption in 3300 and 3500 ORAC units per day.
A blood test showed that the antioxidants were absorbed. However, the increase in plasma ORAC can not explain the consumption of nutrients. He noted that other parts of fruit and vegetables are well absorbed.
Joseph and Shukitt Hale study in mice. Showed that anti-oxidants to prevent the loss of long-term memory in middle-aged rats. Brain cells in these mice might be better suited to respond to chemical stimuli.
Basis of the evidence, we arrive at a daily dose of 3000-5000 ORAC units. However, this must be done by eating lots of fruits and vegetables, and add not only to a certain high-ORAC value left.
Cao said that “it may be that together with nutrients in foods more protective effect of each nutrient alone. ”
ORAC value, which does not disclose
Remember that the ORAC values were in a test tube and does not necessarily lead to bioactivity. There are certain things that I can not say the amount of ORAC.
Some of the antioxidants in the tube can not be absorbed and used by the body.
Antioxidants not all elements of free radicals. This means that antioxidants can be controlled in the diet of a group of free radicals and thus more susceptible to other free radicals.
Similarly, different antioxidants appear on different parts of the body to concentrate. For example, Barbara Hale-Shukitt that rats fed the spinach, and improve long-term memory of rats a diet enriched with strawberries.
Increasing the number of antioxidants that we eat is important, what to limit in practice, how much they can benefit from it. It is a good reason, were forced to increase the consumption of ORAC units 3000-5000 per day. It appears that the Agency can this amount of blood antioxidant properties are preserved strictly regulated. Then, better take with 25,000 units at a time when one fifth of that amount. The excess is excreted from the body and is only a waste of money.
Sun ORAC value does not tell the whole truth. If you have scurvy, for example, do good for Pycnogenol, which is about 20 times “more effective” vitamin C. If the scurvy, vitamin C, but much more important than Pycnogenol .
y that acai is “stronger” than mangosteen or that mangosteen is many times stronger than noni, is meaningless. They each have their strengths. For example, noni can help raise nitric oxide levels, which mangosteen cannot do. But mangosteen appears to be a better antipathogenic than noni.
The Bottom Line
Mix things up. No single food will provide all the antioxidants that you need. A wide variety of healthful foods is key. While ORAC values give us an idea of a food’s relative antioxidant strength, different foods have differing antioxidants and other vital nutrients.
It is also unlikely that you will eat a wide enough variety of foods on a regular basis to provide all the antioxidants that your entire body needs. Quality supplementation may be needed. By adding several of the nutrient dense, high ORAC value exotic juices discussed in this website, you will be on your way to providing what your body needs.
