Parsley belongs to the celery and carrot family and was held such high esteem to the ancient Greeks, that they adorned athletic victors with it.
Parsley is very high in the green pigment chlorophyll which is a detoxifier/chelator of heavy metals, and a deodoriser, masking the odour of other foods. Chewing on parsley after a pungent dish such as with garlic helps to freshen breath. It is also rich in the Vitamin A rich, yellow, carotene pigments such as zeathanthin is necessary for macular health in the eye.
Parsley is an excellent source of Vit A, K and C. It also contains Vit B1, B2, B3, B5, B6, Folic acid, Iron, Potassium, Zinc, Manganese, Magnesium and Calcium! The combination of high Vit C and Iron makes parsley an excellent source of non-haem iron for vegetarians, given Vit C increases the uptake of iron in the body.
