Essential minerals in a vegetarian diet
IRON
The first of the essential minerals, dietary iron comes
in two forms, haem iron and non-haem iron. Haem iron is found in meats
and animal products, while non-haem iron is found in legumes,
wholegrain cereals and green leefy vegetables.
The human body recognises and absorbs haem iron much
better than non-haem iron, absorbing up to 23% haem iron compared with
8% or less for non-haem iron.
Vegetarians can improve the absorbtion of iron from
plant foods by eating foods rich in vitamin C at the same time. Adding
tomato to a green salad or drinking orange juice with your breakfast
cereal, for example.
Some foods inhibit the absorbtion of iron and should be
avoided. Unprocessed bran is one such food so don't eat large
quantities with wholegrain breakfast cereals. Tannin, found in tea,
binds with iron and stops it being absorbed so drinking tea with a meal
is not a good idea.
If you have an iron deficiency, confirmed by a blood
test, you will probably need to take an iron supplement because it is
difficult to boost your iron levels quickly with diet alone. Once your
iron levels are satisfactory you should follow an iron-rich diet and
not rely on the supplement.

ZINC
Like iron, zinc from plant foods is not absorbed well by
the body. The absorbtion is improved by eating some animal protein with
good vegetable sources of zinc. Yogurt with wholemeal cereal or egg on
toast for example.
Legumes, seeds, nuts and wholegrain cereals are all good sources of this mineral.
CALCIUM
The third essential mineral, calcium is needed to
maintain healthy bones and teeth. It is plentiful in dairy products and
is easily absorbed. Tofu and fortified soy drinks also provide calcium.
Leafy vegetables also contain calcium, but the body does not absorb the mineral well from these sources.
Calcium supplements should be avoided if at all possible as they interfere with the absorbtion of iron and zinc.
