Curd,
Yoghurt and Probiotics
So stop feeding it mindlessly... |
I have often written on this blog
(here
and here)
about the useful role antibiotics play in combating life threatening
infections. But I have also been
repeatedly asked by the readers about the side effects of giving antibiotics
and so I reasoned that instead of answering individually to every commenter who
raises the same question again and again let me write out a detailed blogpost
on it to which I can refer them to next time i get asked. So bear with me as I
take you on a slightly detailed tour of the side effects of antibiotics and
what we can do to minimize them.
For those who came late to class
or are just reading this blog for the first time- the short version is -
antibiotics are germ killers, drugs which destroy bacteria in our bodies. now
if you pay careful attention you can see that that I said "bacteria"
and not "harmful bacteria" for antibiotics not only kill off the
disease giving bacteria (called pathogens) but also their harmless cousins
living inside our body (called commensals) which actually have some good
effects on us- an example would be like spraying a weed killer and killing the
grass too.
Now if you think that this killing
off of a few harmless bacteria is of no consequence let me assure you that it
does have some direct effects on our health. The current theory of human health
called the human microbiome theory - says that human bodies are a mass of human
cells and bacterial cells with the bacterial cells outnumbering the human ones
- which means we are more bacteria than human. Kind of a difficult concept to
get around our head isn’t it?
So the theory goes on to say that
as long as these healthy and harmless bacteria dominate our bodies they do two
things for us. Their first help to us is - the good bacteria prevent the
harmful, disease causing bacteria (like Clostridium Difficile - the dysentery
causing bacteria) from multiplying limitlessly and dominating our stomach
(imagine getting daily dysentery or rather don’t) and the second benefit of the
good bacteria is that they produce good things for us like absorbing vitamins -
the intestinal bacteria or our gut bacteria is mainly responsible for absorbing
Vit.B-12 from our guts - from the food which we eat. In the absence of these
bacteria the vitamin is not absorbed and passes straight out through our body-
from the other end- uselessly.
Our Gut has a 100 trillion Bacteria inside it |
So that makes it a no-brainer doesn’t
it? we need these bacteria for better absorption and digestion of our food and
in the absence of these bacteria we are not only losing all the important bits
of the food we eat -getting nutritional deficiencies in the process but even if
we take tablets full of supplements even that is not going to be absorbed but
only lost from our bodies. Hence we need these bacteria to survive and they
need us to thrive- a simple give and take relationship- till death do us part.
Now all this is disturbed -
temporarily- when we take antibiotics. Our digestive system is put out of sync
with our body and we get loose stools called AAD- Antibiotics Associated
Diarrhea, which is by far the biggest side effect of taking antibiotics. And that’s
where some scientists thought up the idea of Probiotics- which is the very
opposite of Antibiotics. If "Anti"-biotics kill bacteria then
"Pro"-biotics help bacteria grow, right? And the way to do it is by
adding live bacteria to the diet through various supplements and food products
like yoghurt and curd.
Fortified Yoghurts come in many sizes |
Some of the commonest probiotics contain
organisms like Lactobacillus and yeasts which are freeze-dried to preserve them
in tablet form. Once inside our stomachs they can gain their original forms,
multiply and restore the good vs bad bacterial balance. The same purpose is solved
by eating yoghurts and curds and fermented products which contain natural
probiotic yeasts and bacteria. Yoghurts are thought to contain single varieties
of bacteria only while natural homemade curds have been found to contain both
yeasts and bacteria in abundant numbers - the more the merrier (better) .
So this has made it simple right? When
you take antibiotics you better take some probiotics too - to prevent the side
effects. But unfortunately it’s not so simple - hard scientific evidence of the
benefit of taking probiotics is still not available and there are still
questions about which are the actual beneficial bacteria and how much to take
and whether the yeasts (which are fungi) can take advantage of an already sick
body with a weakened immune system. Till now, despite numerous studies going on
all over the world, we don’t have clear answers for the doubts whether
probiotics really work as they are claimed to do. The only hard evidence is
from a Cochrane Review
(Johnston,2011)- Cochrane reviews can usually be trusted as good science- after
studying 3400 patients decided that probiotics work and are beneficial to a
certain extent.
So we can conclude off by deciding
that taking Probiotics helps in
preventing the stomach upsets after taking antibiotics even if we don’t know
which antibiotics is taken or for how long it is taken. And natural probiotics
like curds and yoghurts certainly are better than the tablet supplements which
have been stored for months together as dried forms. After all the very definition
of a probiotic is a LIVE bacteria which benefits the host by improving the
intestinal microbial balance and so what good is a tablet which has stayed in a
pharmacy fridge for months together and the bacteria are all dead. If fermented
milk contains the best bacteria which is made into the tablets- then its better
to eat some live yoghurts or curds in that case, right?
All natural, home-made Curds are the best |
So next time you hesitate to take
an antibiotic because antibiotic tablets always gives you a tummy ache and
loose stools - go eat some good, home-made curds and thank the good bacteria
for helping to restore balance inside your body.
P.S. there is one yucky way of
sending in the probiotic bacteria immediately (and directly) to your stomach -
only used in desperate cases - called Fecal Transplant- but let’s not even go
there - I don’t want to talk about it and chase you off my blog forever. So,
just eat curd/yoghurt through your mouth ok?
Remember? when MOM used to give curd rice if you have stomach upset? & that too with 'Aaaavakkaai' ooorukaai!!! perhaps saline transfusion in a palatable oral way !!! I am proud of my ancestors. Thank you Guns for lovely article. your warning at the beginning is really scary !!!
ReplyDeletehahhha...sir, thats just a gentle reminder to be mindful of what we eat..most times we either eat in a hurry or mindlessly in front of a screeen....and we dont even notice what is going in or what it would do to us....thats what i meant....
DeleteDoc, please cut off technical details and give us info in our language, i. e. Layman's language. Moral of the story: Eat curds. Period.
ReplyDeleteThanks a lot for useful posts as these, Doc. Much appreciated.
Joy always,
Susan
oopse..thats what i was planning to d with this one Susan..write it for everyone but seems i didnt. ok...will make more of an effort next time...the thing is we scientists spend all our time communicating with other scientists in alpha/beta/pi mode and we forget that all that jargon is simply to show off that we know it too....i am rebellin against my training to speak normal english..which i am sure i will soon start doing...thanks for the timely reminder.
