A glass of tomato juice makes exercise even more healthy

Exercise is healthy no discussion there but intensive physical exercise increases the production of aggressive molecules that can damage our genetic material. Researchers at Stockholm University discovered that it's possible to reduce the potentially damaging effects of exercise by getting subjects to drink a glass of tomato juice every day.

Free radicals
During bouts of intensive exercise cells make oxygen radicals, which are capable of damaging our DNA. You can see this damage in the blood. The higher the level of 8-oxodG a DNA base pair damaged by oxygen radicals in the blood, the more damage the cells have had to repair.

Moderately intensive exercise reduces the concentration of 8-oxodG in the urine, but intensive exercise increases it. A while ago we wrote about Spanish experiments in which extracts of Phlebodium decumanum reduced genetic damage in runners.

The Swedish study, which will be published soon in Nutrition, suggests that common-or-garden tomato juice has a similar effect.

Study
The researchers got 15 healthy men and women, who were not athletes, to cycle for 20 minutes at 80 percent of their maximal heart rate. The researchers then measured the concentration of 8-oxodG in the blood of their test subjects.

The experiment was carried out under two different sets of conditions. On one occasion the subjects were asked to cycle after having drunk one 150 ml glass of tomato juice every day for five weeks. And the researchers also got the subjects to cycle once after a period of five weeks during which they had not drunk a glass of tomato juice every day.

Results
One glass of tomato juice contains 15 mg lycopene [structural formula shown above]. Epidemiological studies have shown that a diet containing high levels of lycopene reduces the chance of developing prostate cancer, and experiments have shown that lycopene also rejuvenates the skin. Tomato juice also contains forms of vitamin E, vitamin C and polyphenols.

The table below shows that tomato juice supplementation virtually eliminated the rise in 8-oxodG caused by exercise.

Carotenoids in carrots, oranges and tomatoes protect against dementia Lycopene lowers blood pressure Raw tomatoes boost HDL

Carotenoids in carrots, oranges and tomatoes protect against dementia
Epidemiologists at Harvard University conclude this from an epidemiological study in which fifty thousand women participated.

Lycopene lowers blood pressure
The dosage in which lycopene lowers blood pressure is so small that drinking a glass of tomato juice daily should have an effect.

Raw tomatoes boost HDL
If you eat 300g raw tomatoes every day for a month, the concentration of HDL - the 'good cholesterol' - in your blood rises by 14 percent.
