GUT SANITATION SQUAD: PART 2

Hello, and thank you for continuing on to Part 2 of the Gut Sanitation Squad. Trust me, your gut will thank you.


So, in Part 1, we set the foundations: what fiber is, why it matters, how it fuels your microbiome, how it impacts gut disorders, and how your gut adapts. At the end, we left the big question: how does all this science translate into your daily life?


That’s exactly what Part 2 is about. We’ll unpack fiber types, show you where to find them, and explore practical ways to weave them into your meals so that your gut – and, by extension, your whole body – can thrive.



The Two Squad Members

Fiber isn’t one thing; it’s a category. There are two main types, and both play essential roles:


Soluble Fiber:

This type dissolves in water and swells up, forming a gel-like substance in the small intestine. Sounds icky, I know. But, in fact, this gel-like substance is what our gut thrives on. It slows down digestion, stabilizes blood sugar, supports the lowering of LDL cholesterol, prevents post-meal energy crashes, feeds the good bacteria, and keeps us full for a longer period. When the remains of this fiber travel down to the large intestine (colon), it sacrifices itself during the fermentation process, which leads to the production of short-chain fatty acids (SCFAs), the building blocks of our gut immunity – we covered this in Part 1. If fiber were a recipe, the bacteria would be the chefs, and SCFAs would be the powerful bite-sized meals they whip up to keep the gut thriving.


Insoluble Fiber:

As the name suggests, this one does not dissolve in water. It holds most of its integrity as it travels through us and comes out the other end. In fact, our bacteria can’t even ferment it well, so one might wonder what the point is. Insoluble fiber is responsible for the consistency and bulk of our stool. It helps keep our bowel movements regular, and I think it’s safe to say that we all have – at some point – experienced the bad side of this consistency. Constipation (occasional or chronic) often improves when insoluble fiber is on the plate. By binding to water, it softens stool and adds volume, making it easier to pass. Long-term, diets higher in insoluble fiber are also linked with lower risks of diverticulitis and colorectal issues – proof that even the “unfermentable” fibers play a powerful role. Think of it as a gentle brush in your colon, sweeping out old cells and bacteria and keeping the environment clean. That’s why you feel lighter and fresher after this daily ritual.



The Magic Word

If there’s one rule for fiber, it’s this: don’t just aim for more. Aim for diversity. If the word “fiber” makes you think of bland bran flakes, it’s time to refresh that image. Fiber-rich foods can be delicious, colorful, and incredibly varied.

An obvious source of fiber that we all know is fruits and vegetables. But, in reality, fiber is packed in all things nature. Imagine all parts of a plant through the lifecycle: the seeds, the grains, the stem, the leaf, the fruit – every single thing contains fiber.

So, how do we make this practical? Let’s break it down into familiar food groups with examples:

  • Fruits: Apples, pears, raspberries, blueberries, guava, kiwi, bananas

  • Vegetables: Broccoli, carrots, leafy greens, sweet potatoes, eggplant

  • Legumes: Chickpeas, lentils, black beans, peas, soybeans

  • Whole Grains: Oats, quinoa, brown rice, millets, barley

  • Seeds: Chia, flax, pumpkin, hemp, sesame, sunflower

  • Nuts: Pecans, almonds, walnuts, cashews, Brazil nuts


Making The Magic Work For You

Different microbes thrive on different fibers, and research suggests that aiming for 30 diverse plant foods per week is one of the simplest, most effective ways to cultivate a healthy microbiome for long-term health. Now, I know the number 30 sounds like an impossible task, but trust me, it’s not that challenging once you find sneaky ways to fit these into your day. I have prepared a detailed toolkit for people who are ready to take on this challenge, and some of my top tips are listed below:

  • Start by making sure at least one meal in your day has at least 4 bright colors.

  • Add one extra serving of vegetables to lunch or dinner. I like to have cucumber or carrot sticks dipped in Greek yogurt.

  • Swap your white basmati rice (or any other white rice) for brown or red rice – something that has gone through much less processing.

  • Make it a staple to add seeds like chia, ground flax, hemp, pumpkin, sunflower, or sesame into your yogurt, smoothies, or any one-bowl meal.

  • Choose whole fruit instead of fruit juice (even if it is “fresh juice”).

  • Find a recipe you like and cook those lentils kept in the jar at the back of your pantry.

  • Season or cook your meals with herbs like parsley, cumin, mint, oregano, ginger, nutmeg, and turmeric – all offer benefits.

  • Add a crunch to your salads or bowls by adding chopped nuts like walnuts and almonds.

Words of Caution

When it comes to fiber, make sure you do not go from 5 g a day to 25 g a day overnight. If your gut isn’t used to fiber, suddenly loading up can feel like chaos inside – gas, bloating, cramps, or even discomfort that makes you want to quit fiber altogether. This doesn’t mean fiber is “bad for you”. It just means your gut microbes need time to adjust.


Think of your gut as a muscle group at the gym. If you have not lifted heavy weights before, you wouldn’t bench press 80 kilos on the first day, right? Your muscles, joints, and nervous system need time to adapt to a new load. Similarly, if you’ve been on a low-fiber diet for years and suddenly load up on lentils, raw salads, and fiber-rich smoothies, your gut will 100% react. And it’s NOT the kind of reaction you will like.


Just as a smart gym plan starts with light weights, low reps, and gradual progression, your fiber journey should do the same. The key is to introduce fiber into your diet slowly and steadily. Otherwise, it will either pass through you like Niagara Falls or get jammed like New Delhi traffic.


And, as mentioned in Part 1, if you are someone with diagnosed gut issues, be wary of introducing fiber into your diet. You do not need to fear it. All you need is some guidance from a qualified professional.


Another non-negotiable is pairing fiber with adequate water intake and an active lifestyle, including 30 minutes of moderate exercise a day. This is absolutely essential to make sure that the fiber you consume does its job efficiently. Without these two habits, the fiber can make you feel fatigued, sluggish, and bloated.



The Long Game

At its core, fiber is not a quick fix. It is about consistency – showing up on your plate in different colors, textures, and flavors. Once you start, it doesn’t take long to notice shifts: lighter digestion, better energy, fewer crashes, and a sense of balance inside you. And the good news is, it’s growing all around you.


Start today. Add two more vegetables, keep the skin on your fruit, swap in whole grains, and stop fearing lentils and beans.

Because, at the end of the day, you don’t need miracles for your health. You just need fiber.


Thanks a lot for making it to the end! ☺
