Proof mounts on restricted diet

Restricted Diet has long been known to have major benefits for animals. Now a close relative of man has furthered this theory. A long study in the U.S. has concluded with major proof of the health benefits of a nutricious but restricted diet in monkeys. It involved several monkies of equal age, half with restricted calorie intake and the other half with an unrestricted diet.

The rate of cancers and cardiovascular disease in dieting animals was less than half of those permitted to eat freely.

Whether the same effects would be seen in humans is unclear, although anecdotal evidence so far suggests people on a long-term calorie-restricted diet have better cardiovascular health.

The precise mechanism is yet to be established: theories involve changes in the body's metabolism or a reduction in the production of "free radical" chemicals which can cause damage.

Purines Explained

I will try to explain 'Purines' that I mentioned in my previous blogpost.

Purines are natural substances found in all of the body's cells, and in virtually all foods. The reason for their widespread occurrence is simple: purines provide part of the chemical structure of our genes and the genes of plants and animals. A relatively small number of foods, however, contain concentrated amounts of purines. For the most part, these high-purine foods are also high-protein foods, and they include organ meats like kidney, fish like mackerel, herring, sardines and mussels, and also yeast.

Purines are metabolized into uric acid

When cells die and get recycled, the purines in their genetic material also get broken down. Uric acid is the chemical formed when purines have been broken down completely.

Because uric acid is formed from the breakdown of purines, low-purine diets are often used to help treat conditions like gout in which excessive uric acid is deposited in the tissues of the body.
