In the process O2 is taken in and CO2 is released. Carbon is also released as CO2 when organisms die and decay (work of decomposers). A: The carbon dioxide-oxygen cycle is the cycle in which living things (such as plants and animals) take in oxygen and let out carbon dioxide..
Beetroot juice 'helps lower blood pressure': A glass a day can reduce it by 7%, say researchers. Drinking beetroot juice every day could help to lower blood pressure, say researchers. They found a dose of eight ounces â around one cup â may help people with high blood pressure, cutting their readings by about 7 per cent. Tests suggest the effect is produced by beetrootâs naturally high levels of nitrate.
The results appear in Nutrition Journal. In the study, 15 men and 15 women drank either 17.6 ounces of a beet juice beverage consisting of about three-fourths beet juice and one-fourth apple juice, or a placebo juice. They were then monitored for 24 hours. The same procedure was repeated two weeks later, with those who drank the placebo on the first round receiving beetroot juice on the second. Among both men and women, the results showed a trend to lower systolic blood pressure six hours after drinking the beet juice. But when researchers limited their analysis to men only, they found a significant reduction of about 4.7 points among those who drank the beetroot juice.
