The caloric-oxidative stress theory of aging.



Numerous studies have shown that rats fed on a low calorie diet lived longer and were more youthful than rats that received average or high calorie diets. As a result of these studies, scientists have proposed a theory that low caloric intake could slow down aging, after observing that caloric-restricted rats live almost 60 percent longer than expected. Another theory closely related to the caloric theory, is the theory of oxidative stress. Cells use calories from food and oxygen to generate the energy that keeps the body running. It is through this process, that free radicals are produced - molecules that are highly reactive and will attack the replication structures inside the cells. It is estimated that the DNA in each cell will be attacked 100,000 times in a 24-hour period. Fortunately, there are repair systems, but they are not foolproof. Every time a cell divides, some mistakes are made in the DNA-copying process and these errors accumulate over time. Sooner or later, a cell line will have accumulated so many errors in its DNA, that it may transform into a tumor cell. Many researchers believe that oxidative stress, which leads to a gradual destruction of intracellular structures by free radicals, is one of the major causes of aging. An example of oxidation, is a cut apple which turns brown after a period of exposure to air, or an old yellowed newspaper. Taking antioxidants through dietary sources and as supplements may help in this regard.

Also consider this, the more you eat, the more toxins you will be exposed to. With the ever increasing amounts of toxins present in our food supply, we are exposed to heavy metals, benzene and other DNA damaging compounds. So dietary restriction helps in this regard too.

The Solution?

Dietary Recommendations include:

Fresh fruits(unless one is diabetic)and vegetables (wash all fruits and vegetables well)

Fruit pectin has been shown to be beneficial, in the reduction of certain cancers

Complex starches, such as beans, brown or wild rice, whole grains, oatmeal, and nuts

Fish, white meat of poultry, occasional red meat, in the stated order of preference.

Low fat content except for, good fats such as flax seed oils, extra virgin olive oil, sesame seed oil, etc

(Those with specific medical conditions should follow the advice of their medical practitioner)

The utilization of mind-body control practices

Ongoing contemporary research suggests that mind-body practices can slow down aging.

Among the ancient Chinese, it was known that those who practiced Tai Chi were healthier and lived to be much older than others. Recent research on yoga has found that the practice significantly decreases oxidative stress. A study on qigong practitioners found that the turnover of cells had been greatly reduced by the practice. In addition to the above practices, it has been found that certain breathing techniques can be utilized to control hypertension and stress related disorders.

It would seem that the following are probably the best and most affordable way to stay younger longer:

Dietary caloric restrictions, along with spiritual periods of fasting

Antioxidants from dietary and supplementation sources

The utilization of mind-body control practices

Increasing high quality water intake (flushes toxins and controls hunger)

Moderate daily exercise and stretching
