The British government are the only
government that I am aware of to have done a study over time on the depletion
of the nutrient value of food caused by modern farming methods. The study that
I am referring to was started in the 1930's and concluded in the 1990's. The
years 1940 and 1992 are of particular importance in the study. A selection of
vegetables, fruits and meats from those two particular years were compared in
the raw and, where appropriate, cooked states to determine the loss of critical
minerals such as calcium, iron, magnesium, potassium, zinc etc.
A very brief summary of the findings of the losses over this 52 year
period is as follows: vegetables lost on average 31% of their mineral content;
fruits lost on average 23%; and meats lost on average 30%. There is no reason
to suppose this loss of essential nutrients hasn't continued from 1992 to the
present time. The reasons for the losses are modern methods involving intensive
farming, the mechanisation of farms, fertilizer policy and the use of chemicals
and sprays on crops.
That particular study just related to the state of the land that the
selection of vegetables, fruits and meats came from. Whilst the condition of
the land from which products are sourced is important, the other variables to
consider with food in order to get the best nutritional value from it is: how
fresh is it; how is stored; and how is it cooked ? Vital nutrients can be lost
with cabbage, for instance, simply by overcooking it. These variables are such
that there is no guarantee that you are getting all the nutrients that you need
on a daily basis from what you consume.
If we cannot derive
all the vitamins, minerals and fibre we need daily from the food we eat, what
can we do to compensate? The answer to that question is to take supplements to
make up for the deficiency in the diet. A good way to do this is to take a multi-vitamin
and mineral tablet or capsule daily. Most of these contain all the essential
vitamins and minerals required to maintain good health, and compensate for any
deficiencies in the diet. These tablets or capsules can be obtained from health
food shops, from the major supermarkets or can be obtained from suppliers via
the Internet.
People
concerned about aging could additionally take Brewer’s Yeast on a daily basis which
usually comes in tablet form. Brewer’s Yeast is an excellent food supplement
containing large amounts of iron, magnesium zinc and other minerals, as well as
essential amino acids and all the B vitamins.
