Beetroot

The beetroot, also known as the table beet, garden beet, red beet or informally simply as beet, is one of the many cultivated varieties of beets (Beta vulgaris) and arguably the most commonly encountered variety in North America, Central America and Britain.

Uses

The green leafy portion of the beet is also edible. It is most commonly served boiled or steamed, in which case it has a taste and texture similar to spinach.

Beetroot are a rich source of potent antioxidants and nutrients, including magnesium, sodium, potassium and vitamin C, and betaine, which is important for cardiovascular health. It functions by acting with other nutrients to reduce the concentration of homocysteine, a homologue of the naturally occurring amino acid cysteine, which can be harmful to blood vessels and thus contribute to the development of heart disease, stroke, and peripheral vascular disease. Betaine functions in conjunction with S-adenosylmethionine, folic acid, and vitamins B₆ and B₁₂ to carry out this function.

Additionally, several preliminary studies on both rats and humans have shown betaine may protect against liver disease, particularly the build up of fatty deposits in the liver caused by alcohol abuse, protein deficiency, or diabetes, among other causes. The nutrient also helps individuals with hypochlorhydria, a condition causing abnormally low levels of stomach acid, by increasing stomach acidity.

Other studies have found the positive effects beetroot juice can have on human exercise and performances. In studies conducted by the Exeter University, scientists found cyclists who drank a half-litre of beetroot juice several hours before setting off were able to ride up to 20 per cent longer than those who drank a placebo blackcurrant juice.

Betanin, obtained from the roots, is used industrially as red food colourants, e.g. to improve the color and flavor of tomato paste, sauces, desserts, jams and jellies, ice cream, sweets and breakfast cereals. From the Middle Ages, beetroot was used as a treatment for a variety of conditions, especially illnesses relating to digestion and the blood. Bartolomeo Platina recommended taking beetroot with garlic to nullify the effects of 'garlic-breath'.
