Beetroot has been getting a lot of coverage in the news. It has been linked with better stamina, improved blood flood and lower blood pressure.
Beetroot became popular in Roman times and it was used to treat fever, constipation, wounds, skin problems - and was used as an aphrodisiac.
Researchers have known for some time that juice may help lower blood pressure, but in 2010 UK researchers revealed that nitrate is the special ingredient in beetroot which lowers blood pressure and may help to fight heart disease.

Nutrients and phytochemicals
Beetroot is an excellent source of folate and a good source of manganese,[6] and contains betaines which may function to reduce the concentration of homocysteine,[7] a homolog of the naturally occurring amino acid cysteine. High circulating levels of homocysteine may be harmful to blood vessels and thus contribute to the development of heart disease, stroke, or peripheral vascular disease.[8] This hypothesis is controversial as it has not been established yet whether homocysteine itself is harmful, or whether it is just an indicator of increased risk for heart disease.[9]
The red colour compound betanin is not broken down in the body, and in higher concentration may temporarily cause urine and stool to assume a reddish colour; in the case of urine this is called beeturia.[10] This effect may cause distress and concern due to the visual similarity to hematuria (blood in the urine) or blood in the stool, but is completely harmless and will subside once the food is out of the system.
