Looser skin and sweeter than an orange — the parent of most easy-peel citrus.
Mandarin is a citrus fruit, and citrus earns its reputation: high vitamin C, low
calories, and a real effect on how much iron you absorb from the rest of your meal.
The white pith carries most of the fibre and flavonoids. Peeling it away entirely removes a meaningful part of the benefit.
The practical value of citrus is not immune boosting. It is that vitamin C converts plant iron
into a form your gut absorbs several times better.

Squeeze it over iron-rich food. Dal, spinach, lentils —
this is the single most useful habit involving citrus, and it can multiply the iron you
actually absorb from that meal.
Keep some pith. The white layer holds
fibre and flavonoids that the juice does not.
Roll it firmly before
juicing — it breaks the segments and yields noticeably more
juice.
Zest before you juice. The peel oils carry most of the aroma and
they are impossible to get once the fruit is squeezed.
Vitamin C reduces dietary iron from the ferric to the ferrous form, which the
gut absorbs far more readily. The effect is large: adding a vitamin C source to a plant-based
meal can increase iron absorption several-fold.
Working against you, tea and coffee
contain tannins that block iron absorption. If iron is your reason, leave an hour either side
of the meal before your chai.
Acid reflux: citrus is a common trigger. Personal tolerance
varies.
Tooth enamel: frequent citrus, particularly as juice sipped
over time, erodes enamel. Rinse with water afterwards and do not brush
immediately.
Diabetes: whole fruit over juice, portion aware, and better eaten
with protein or fat than alone.
IBS: several fruits are high-FODMAP
and commonly trigger symptoms — tolerance is personal.
Kidney
disease: potassium may need limiting. Ask your doctor for your numbers.
