In recent years,
there is an enormous upsurge in awareness about use of Prebiotics and
probiotics in the daily diet. This has resulted in enormous marketing of
related dietary supplements. This ushers in for the use of natural, home based,
cost effective prebiotics that can be given across all ages. This post is to
guide physicians in counselling patients about the right use of pre and
probiotics. Regular intake of pre and probiotics will help to optimize
intestinal microflora. Infants at birth have sterile gastro intestinal tract
(gut), but bacterial colonization occurs rapidly. The regulation of the
intestinal defence system is essential for the prevention of immunological
diseases such as asthma, eczema, allergic rhinitis, type 1 diabetes mellitus
and list goes on.
Tamilian
cuisine includes foods like idly, aapam, koozh, kali which basically involves
fermentation in their preparation. Such processes not only improve the flavour
but increases the probiotic content and the bioavailability of essential micronutrients
(vitamins and minerals) to larger extent.
These
form the array of traditional pre and probiotics. These are non-digestible fibre
foods with minimal digestion in the small intestine and the much undigested
part will be fermented in the large intestine. To explain in abstract, in a
garden the seeds (probiotic bacteria) is added while the water and fertilizer (prebiotic
fibre) is essential for the seeds to grow and flourish. In the same way, the
fermentation feeds the beneficial bacterial colonies (probiotic bacteria)
resulting in better gut outcome and reduced health risk.
Scientific
literature indicates that increased prebiotic fibre intake supports immunity,
digestive health, bone density, weight management, and brain health. Siddha
list of prebiotics include green banana, onion, garlic, barley, beans, apple
with skin, potato with skin.
Unripe banana powder:
Low
in sugar and high in resistant starch (degraded on heating) can help diabetics
better control of glucose. Vazhai Kacchal as proposed by the Pathartha Guna Sinthamani
is capable of relieving irritable diarrhea, bleeding in ano, polyuria and
stomach ulcers.
Slow digesting,
low glycemic starch, metabolised in the small intestine, resistant starch,
insoluble dietary fibre, which resists digestion in the small intestine and reaches
the large intestine where it is fermented.
The
uses of green banana flour are that it addresses issues of digestibility,
insulin, glycemic response, colonic health and fermentation, satiety and other
metabolic problems. Apart from being potassium rich, it’s fermentation promotes
the growth of beneficial bacteria (R.bromii, Akkermansia, Bifidobacteria) which
help in tacking growth of potentially harmful bacteria and diarrhoea. Hence it
can be termed to be a Prebiotic. The colonic fermentation produces butyrate
which apart from being a primary nutrient for colonocytes, is also a
facilitator in gut tissue development, immune modulation, oxidative stress
reduction and diarrhoea control through sodium reabsorption.
Banana powder when mixed with
curd, fermented staple Tamilian foods will render the probiotic effect as well.
