Oranges are a great source of vitamin C, B vitamins, vitamin A, calcium, iron, carotenes, pectin, potassium, and flavonoids such as hesperidin which has anti-inflammatory and antioxidant properties. Oranges also contain a good amount of fibre.
Citrus pectin is a great binder for toxins. It can bind to toxins such as heavy metals, like mercury, as it goes through your digestive system, without binding to nutrients.
