Zinc and Taste Perception
It has become
well recognised that symptoms of Covid 19 include a loss of the sense of taste
and smell. These two senses work together and have long been known to be
affected by colds and respiratory infections.
These senses
often return after recovery but with some sufferers of Covid 19 the loss of
taste or smell, and sometimes both, persists for several months.
Loss of the sensations of taste and smell can
really affect the enjoyment of food and drink and hence intake.
One of the items that has been associated with
a loss of taste is an inadequate zinc intake. From experience, this does help
some individuals to recover their sense of taste and smell plus is being used
by researchers assisting people who have lost these senses.
Zinc is present in many foods particularly in
red meat.This provides about a third of the zinc in the diet.
Zinc is also found
in milk, cheese, eggs, shellfish, nuts and peas, beans and lentils.
Zinc also helps with
producing new cells, and is involved in the metabolism of carbohydrate, fat and
protein as well as being involved in wound healing and functioning of the
immune system.
It is well recognised that males need more zinc
than females as it is required for male fertility. 9.5mg a day for men (aged 19
to 64 years) and 7mg a day for women.
If you do not think you are having enough zinc and a supplement would be
helpful, make sure you take this some time apart from supplements such as iron
to be effective.
Also do not take more than 25mg of zinc supplements a day
unless advised to by a doctor.
