In today’s India, digestive complaints such as constipation, bloating, irregular bowel habits, fatty liver, diabetes, and obesity are rising rapidly. While many patients focus on protein intake, supplements, or detox plans, one critical nutrient is consistently under-consumed – dietary fibre.
According to the 2024 ICMR-NIN Dietary Guidelines for Indians, adults should consume 25 to 30 grams of fibre per day. However, national surveys show that nearly 70 percent of Indians fail to meet this target.
For gastroenterologists and functional medicine specialists, fibre is no longer considered “roughage.” It is a biological regulator that shapes the gut microbiome, supports metabolic health, and protects the intestinal barrier.

Dietary fibre refers to plant-based carbohydrates that resist digestion in the small intestine. Unlike proteins and fats, fibre reaches the colon largely intact.
This resistance to digestion is what makes fibre powerful.
Instead of being absorbed as calories, fibre:
Modern science classifies fibre beyond just soluble and insoluble. Viscosity and fermentability are equally important.
Soluble fibre dissolves in water to form a gel-like substance.
Sources in India include:
Benefits:
Insoluble fibre does not dissolve in water.
Common Indian sources:
Benefits:
Found in:
Resistant starch acts like fermentable fibre and improves insulin sensitivity.
A healthy Indian diet must include a mix of all these forms.
When fibre reaches the colon, gut bacteria ferment it.
This fermentation produces short chain fatty acids including:
Butyrate:
Low fibre diets reduce butyrate production and promote harmful bacterial metabolites.
This is one reason why fibre and gut health are directly linked.
Fibre does more than improve digestion.
It influences hormonal signaling.
Short chain fatty acids stimulate release of:
These hormones:
For patients with prediabetes, obesity, or fatty liver, fibre acts as a natural metabolic regulator.
Dr. Gaurang Ramesh often emphasizes that gut-based metabolic correction starts with fibre diversity, not restriction.
The updated 2024 Dietary Guidelines for Indians recommend:
This shift addresses the growing burden of:
In Bengaluru and other urban centers, refined maida-based diets are replacing traditional millet and pulse-rich meals, widening the fibre gap.
Recent surveys show:
Consequences include:
In clinical practice at Arka Anugraha Hospital, many patients with irregular bowel movements simply lack adequate fibre intake.
Fibre increases stool bulk and frequency. It remains the first-line therapy for functional constipation.
However, hydration is mandatory.
Without adequate water, fibre can worsen hard stools.
Research shows that soluble fibre improves IBS symptoms.
Insoluble fibre such as wheat bran may worsen bloating in some patients.
Individual tolerance matters.
Fibre reduces straining during bowel movements.
It lowers risk of bleeding and prolapse.
High fibre intake reduces intraluminal pressure in the colon and decreases diverticular complications.
These are rich in insoluble fibre and micronutrients.
Provide soluble fibre and protein.
Fruits
Incorporating these daily easily reaches 25 to 30 grams.
Isabgol or psyllium husk is a gel-forming soluble fibre.
Benefits:
However:
At Arka Anugraha Hospital, fibre supplementation is personalized rather than generalized.
If high fibre increases bloating, consider:
Advanced tests such as hydrogen breath testing or anorectal manometry may be required.
Dr. Gaurang Ramesh integrates diagnostic precision before advising aggressive fibre loading.
Increase fibre gradually.
Steps:
Sudden high fibre can cause gas due to rapid microbial fermentation.
Breakfast
Vegetable oats upma or ragi porridge
Mid-morning
Guava or papaya
Lunch
Jowar roti, rajma, spinach sabzi
Evening
Roasted chana
Dinner
Brown rice, moong dal, lauki
This can provide approximately 28 to 32 grams of fibre.
Consult a gastroenterologist if you experience:
Fibre is powerful but not a substitute for diagnosis.
Long-term success involves:
With proper guidance, patients can maintain gut resilience and systemic health.
Dietary fibre is not optional. It is foundational to gut health, metabolic regulation, and long-term disease prevention.
The 2024 ICMR guidelines provide clear targets, but personalization remains essential.
Incorporating traditional Indian high fibre foods, maintaining hydration, and gradually increasing intake can transform digestive health.
If symptoms persist despite dietary correction, structured evaluation can help identify underlying motility or microbiome disorders.
