I
have gone off sugar and yeast for Lent this year. Sugar I can cope
with, but yeast in practical terms means going off white bread and
many other breads. And guess what – I feel great! I do not want to
say that I did not feel great before, but – I definitely feel
greater than before!!! Lighter, would be one word to describe how I
feel. Even more alive, would be another way to describe it.
At
the same time I wonder why many of my clients seem to be intolerant
to wheat. Not particularly to gluten. But to wheat. How come that
wheat, which along with other grains has been a staple food for
centuries, is now causing so many problems?
The
simple truth is that wheat is not what it used to be. In ‘Lose
Wheat, Lose Weight’, Dr. Dawn Hamilton points out that there are
major changes in the way that modern wheat is cultivated and stored,
and in how bread is baked.
Up
to the 1950s wheat was grown on land that was regularly manured. It
would be harvested and then dried thoroughly to prevent mould
formation. It was then stored for months to mature. Only then would
it be considered suitable for milling into flour. In the bakery the
flour was then mixed with yeast and left to rise. This process might
take up to 24 hours to complete. It was kneaded, shaped and proved
again before baking. This produced a tasty wholesome loaf.
Nowadays
wheat is grown using chemical fertilisers and sprayed with pesticides
and fungicides while it is in the field. It is harvested and then
sprayed with a chemical (potassium bromate) to ‘mature it’ in 48
hours before being milled into flour. It is also common practice to
irradiate wheat to avoid insect contamination. During the milling
process the wheat germ is removed to improve shelf life.
Unfortunately this removes much of the natural goodness – the germ
contains Vitamin E and many B vitamins. The bran is removed,
drastically reducing the fibre. The natural yellow colour of the
wheat is not considered aesthetically pleasing and so the flour is
bleached using banzoyl peroxide which then has to be neutralised with
calcium carbonate (i.e. Chalk). Then preservatives and conditioners
are added to improve the texture. Vitamins are added back in, but not
necessarily in a form that the body finds easy to assimilate.
In
addition to flour, the average mass-produced loaf also contains
accelerators such as ammonium
chloride
to speed up the process of rising. Bakers use ‘flour improvers’
(e.g. soya flour) and
emulsifiers
such as sodium stearyol lactylate. Preservatives are also added so
that your loaf can
last
for a few days in the bread bin. The result of all of this, comments
Dr. Hamilton, is that “the amount of nutrition we get from many
wheat based foods, including cereals and pasta, is poor. Eating a
diet that is dominated by wheat means exposing oneself to a build up
of chemicals.“
And
that's it. If you have weetabix for breakfast, a sandwich for lunch
and then pasta for your evening meal, you aren’t really doing
yourself any favours. I don't say that you should eliminate wheat
from your diet completely but if you do eat a lot of wheat you might
want to reduce your intake and consider some alternatives. Have a
varied diet and if you have any issues with food intolerances, wheat
or otherwise, please feel free to get in touch.
