Mandarin Health Benefits
Mandarin health benefits come from eating the whole fruit: vitamin C, fibre, hydration, and a naturally portioned snack.
A mandarin is a small citrus fruit with a straightforward nutritional profile: vitamin C, dietary fibre, natural sugars, water, and a range of plant compounds including flavonoids and carotenoids. This page describes what the fruit contains. For guidance on health conditions or dietary requirements, Healthdirect and Eat for Health are the relevant Australian resources.
What mandarins contain
Per 100g of edible flesh (FSANZ data):
- Energy: 47 calories (197 kJ)
- Vitamin C: 28 to 40mg
- Dietary fibre: 1.6g (soluble and insoluble)
- Carbohydrate: 9.8g
- Beta-carotene and cryptoxanthin (carotenoids responsible for orange colour)
- Flavonoids including hesperidin and nobiletin
- Water content: approximately 86 percent
Citrus Australia describes citrus as the richest fruit source of the antioxidant hesperetin. The flavonoids in mandarins, including hesperidin and nobiletin, are the subject of ongoing laboratory research into their properties. Human evidence at typical dietary intakes is still developing.
Vitamin C
Vitamin C from mandarins contributes to immune function, collagen production, and absorption of non-haem iron from plant foods. The amount in a single medium mandarin (28 to 40mg) covers a meaningful portion of the adult daily reference value set by the NHMRC (45mg for non-pregnant adults).
Whole fruit delivers vitamin C alongside fibre and other compounds. Mandarin juice provides similar vitamin C but with most of the fibre removed.
For more detail on vitamin C content by variety and size, see Vitamin C in mandarins.
Fibre
The 1.6g of fibre per 100g includes both soluble and insoluble types. Soluble fibre slows digestion; insoluble fibre adds bulk. The fibre in the whole fruit is largely absent from mandarin juice, which is one reason whole fruit is generally preferred to juice in Australian dietary guidelines.
Carotenoids
Beta-carotene and cryptoxanthin give mandarin flesh its orange colour and convert to vitamin A in the body. Mandarins also contain small amounts of lutein and zeaxanthin, carotenoids associated with eye health in broader dietary research. The amounts per mandarin are modest compared with leafy green vegetables.
Mandarins as part of a diet
The Better Health Channel (Victorian Government) states that a high intake of fruit and vegetables is associated with lower rates of certain chronic conditions in population studies. Mandarins contribute to overall fruit intake as one variety among many. The Eat for Health guidelines cover the recommended daily serves of fruit for Australian adults.
