In the realm of nutrition, few elements are as underappreciated—and yet as vital—as dietary fibre. Often overshadowed by protein or the latest superfood trend, fibre quietly performs critical roles in our body that can transform our health. Think of it as the unsung hero of your digestive system and beyond.
In this article, we’ll explore why fibre is indispensable, where to find it, and how to make it a more prominent part of your daily routine.
What is Fibre?
Fibre is a type of carbohydrate that your body cannot digest. Unlike other carbs that are broken down into sugar molecules, fibre passes through your digestive tract mostly intact. This might sound unimportant, but that very characteristic is what makes it so beneficial.
Fibre comes in two main forms:
- Soluble fibre: Dissolves in water and forms a gel-like substance. It helps lower blood cholesterol and glucose levels.
Sources: Oats, apples, citrus fruits, barley, psyllium. - Insoluble fibre: Adds bulk to the stool and helps food pass more quickly through the stomach and intestines. It is essential for preventing constipation.
Sources: Whole wheat flour, wheat bran, nuts, beans, vegetables like cauliflower and potatoes.
The Health Benefits of Fibre
Fibre plays several superhero roles in our bodies:
1. Digestive Health
Fibre improves bowel regularity and prevents constipation. A healthy gut microbiome thrives on fermentable fibres, particularly those found in legumes, fruits, and vegetables.
2. Heart Health
Soluble fibre can help lower LDL (bad) cholesterol by binding to cholesterol particles in the digestive system and removing them from the body. This may reduce the risk of heart disease and stroke.
3. Blood Sugar Control
Fibre slows the absorption of sugar, improving blood sugar levels. For people with diabetes or insulin resistance, this is a powerful tool in maintaining glycaemic control.
4. Weight Management
High-fibre foods are more filling, reducing hunger and helping you eat fewer calories naturally. Fibre-rich diets are associated with lower body weights and healthier body composition.
5. Cancer Prevention
A fibre-rich diet may lower the risk of certain cancers, particularly colorectal cancer. The exact mechanisms are still being studied, but fibre’s role in gut health and toxin elimination is significant.
6. Hypertension prevention
Fibre also plays an important indirect but powerful role in managing hypertension (high blood pressure). While not a replacement for medication or medical management, a high-fibre diet is a key component of dietary strategies such as the DASH (Dietary Approaches to Stop Hypertension) diet, which is widely recommended for controlling blood pressure.
Studies have shown that increasing fibre intake by 10–25 grams per day can lower systolic blood pressure by 2–4 mmHg on average.
Soluble fibre has shown better effects when combined with potassium-rich diets.
How Much Fibre Do You Need?
The Indian Council of Medical Research (ICMR) recommends:
- Men: ~38 grams per day
- Women: ~25 grams per day
However, most Indians consume far less—often under 15 grams daily—due to low intake of vegetables, fruits, and whole grains.
Easy Ways to Increase Fibre Intake
- Start your day with oats or multigrain porridge instead of refined breakfast cereals.
- Include whole fruits (not juice) as snacks. Guava, pears, papaya, and apples are excellent choices.
- Choose whole grains like brown rice, millets (ragi, jowar, bajra), and whole wheat chapatis.
- Add legumes and lentils (chana, rajma, moong, masoor) to your lunch or dinner.
- Sprinkle seeds (chia, flax, sesame) over your meals or curd bowls.
- Consume vegetables with peels wherever appropriate, e.g. cucumbers, bitter gourd etc
A Word of Caution
When increasing fibre, go slow and hydrate well. A sudden spike without enough water can cause bloating or discomfort. Gradual increase over 7–10 days is ideal.
Conclusion: Fibre as a Daily Habit
Fibre isn’t just a tool for bowel regularity—it’s your body’s natural ally in preventing disease, stabilising blood sugar, managing weight, and nurturing your gut.
As a doctor and dietitian, I’ve witnessed the transformative effects of simple dietary changes. By making fibre-rich foods a daily habit, you’re investing in lifelong health and vitality.
