includes milk or eggs
will contain sufficient
protein of a high
biological protein.
protein from plant sources, with
the exception of soya, has a low
biological content, which means
that one or more of the essential
or indispensable amino acids
needed by the body are missing.
If proteins from different plant sources
are eaten together, the amino acid
content of the plant proteins will
complement each other.

with adequate intakes of
vitamin D among

Low vitamin D status may be due to a combination of low
exposure to sunlight and the type of vegetarian die followed,
particularly if milk and milk products are excluded.

and dairy products, so vegetarians

are likely to have adequate intakes of
calcium.
non-haem iron is obtained freom sources such as eggs, cereal
foods, green vegetables, nut and pulses. It is important to
remember that if vitamin C is consumed from fruit, fruit juices
and vegetables this will enhance the absorption of non-haem
iron.
