Buckwheat a humble source of quality proteins |
Due to little exposure,
many people have a lot of
misunderstanding about Vegetarian Nutrition.
Some may have been influenced
by the
incomprehensive health education system,
some may have been misled by the
media,
while others may have been illusified by
their own personal experience,
when they perceive vegetarian diet being incomplete or mal-nutritive.
In fact, if one were to spend some time flipping
through
some science text book or scientific publication,
it’s easy to find out that
plant based diet is nutritious.
However, because vegetarianism is not deemed
as
a concerned issue in our modern society,
even though, some people may raise the
topic on a dining table,
eventually not many will seriously research into
vegetarianism.
This is why the misunderstanding
of vegetarian nutrition is
always persistent,
if not worsen by “hear-say” across dining tables.
Among all pitfalls and myths about vegetarianism,
the most
common one is about proteins:
Proteins, from biological perspective,
is ubiquitous (i.e.
everywhere).
As long as the food we take is a living thing,
including animals,
plants, algae, fungi and bacteria,
it
contains proteins.
Simply, all living things
are made up of cells and cells
must be made of proteins!
Hence, when we hear that vegetarians
are not getting any
protein as they don’t consume meat,
we know it’s absolutely incorrect.
Regarding proteins,
vegetarians, however, have to take note
of how to take the right quantity of the right quality proteins:
In plant based diet,
although, all plants contain proteins,
but the distribution of proteins across different plant parts is not even.
With
some exceptions, in general,
leaf (e.g. Choy-sum, Bak-Choy),
flower (e.g. Lily
flower, Ba-wang-hua),
fruit (e.g. tomato, eggplant) and
stem (e.g.celery, Lily
bulb) contain less proteins
than
root (e.g. sweet potato, tapioca) and
seeds
(e.g. soybean, millet).
Therefore, if there is a need to increase proteins
intake,
one will need to take more of the root and seeds.
The quality of a protein refers to
the completeness of all
18 types of amino acids
that make up the protein.
If a food item contains
proteins with 18 types of amino acids,
then it’s deemed a source of good
quality protein.
If a protein contains less than 18 types of amino acids,
then
it’s deemed as sub-quality protein.
In general, scientists perceive that meat
proteins
(containing all 18 types of amino acids)
is always better than plant
proteins
(with some exceptions like beans and some seeds).
This is because
plant
proteins are usually lack of one or two types of amino acids.
That is why we
often hear the remarks that,
in order to improve proteins intake,
one must
consume meat, and that
the poor quality of plant proteins will cause
malnutrition.
But, those are very biased notions.
Every plant food is lack of
different amino acids.
In a plant based regime,
one is encouraged to diversify
the intake of different vegetables and grains,
so that each plant food will
complement each other.
There is never an issue of amino acid deficiency.

On another matter,
a lot of vegetarians are over-worried
about proteins deficiency
to the extent of compulsively consume
large amount of
soybeans, tofu, beans and soy milk.
This is not recommended for a vegetarian.
Although beans are very high in proteins,
they are also very “acidic”.
“Acidic”
food refers to food
which causes metabolic burden in our body.
If our overall
intake of acidic food increases,
leading to our metabolic burden worsening,
our
internal organs will age faster or become susceptible to diseases.
For developing children and sick people who needs a lot of
proteins,
it’s suggested that they take alkaline grains with good quality
proteins
(ie with all 18 types of amino
acids).
The examples are millet, quinoa, amaranth seeds and buckwheat.
These
staple grains can be taken on daily basis and
will not cause substantial
metabolic burden to the body.
With these proper knowledge and critical analyses
about
plant based diet,
we now understand that proteins
has never been an issue and
should not deter our confidence in a plant based regime.
Next, we will discuss about the pitfalls and myths about
carbohydrates in a vegetarian diet.

To complete amino acid, it is to combine legumes with grains.
ReplyDeleteRegarding carbohydrates, it would be better to use simple carbohydrates so that the body won't be tired easily otherwise the body uses so much energy to convert complex carbohydrates into simple carbohydrates.
That's what I read.
combination and diversification is the trick, it does not necessary have to be just legume and grain.
ReplyDeletecomplex carbo is not necessarily a bad thing, as it will be discussed on the subsequent post :)
