Gut bacteria play an important role in human health, such as supplying essential nutrients, synthesizing vitamin K, aiding in the digestion of cellulose, and promoting angiogenesis and enteric nerve function. Recently, Dr. Saurabh Sethi, AIIMS-trained gastroenterologist and liver specialist, also educated at Harvard and Stanford, took to his Instagram account and highlighted 5 simple swaps that can make a big difference for your gut.
Gut health can significantly influence your overall health and body. Trillions of microorganisms reside in the digestive tract that may include bacteria, fungi, and virus. The complex ecosystem is also known as gut microbiome. It functions as a supportive organ that can break down carbohydrate, synthesize vital vitamins, and regulate immune response. Gut health can affect digestive health, immune health, energy levels, mood, and even your metabolism.
While major lifestyle changes can boost gut health, experts suggest that even small dietary swaps can make a noticeable difference over a period of time. It is imperative to replace processed foods with gut-friendly food options that can support healthy digestion, nourish beneficial gut bacteria, and bring down inflammation.
According to a study published in National Library of Medicine, “Gut bacteria play an important role in human health, such as supplying essential nutrients, synthesizing vitamin K, aiding in the digestion of cellulose, and promoting angiogenesis and enteric nerve function.” 1
Recently, Dr. Saurabh Sethi, AIIMS-trained gastroenterologist and liver specialist, also educated at Harvard and Stanford, took to his Instagram account and highlighted 5 simple swaps that can make a big difference for your gut. 2
1. Replace Regular Bread With Whole Grain Sourdough: Dr Saurabh Sethi recommended to replace white bread for whole grain sourdough. The gut doctor said, "Sourdough's natural fermentation lowers its glycemic impact and produces compounds that support gut bacteria." Sourdough bread, produced from whole grain, is easier to digest when compared with highly refined white bread. The fermentation procedure used in sourdough can also help break down some specific compounds that can make nutrients easier for the body to absorb.
Also, whole grain sourdough offers more fibre that can support digestion and feed the beneficial gut bacteria.
2. Swap Flavoured Yogurt For Plain Kefir, Greek Yogurt, Or Dahi: The gut doctor suggested to replace flavoured yogurt with plain kefir, greek yogurt, or dahi. He said, "flavoured yogurts are loaded with sugar that kills the very bacteria you are trying to grow."
It is worth noting that flavoured yogurts often include added sugars and artificial ingredients that may not support gut health when consumed on a regular basis. Instead, it is ideal to select plain kefir, Greek yogurt, and curd as they can offer helpful probiotics without excess sugar.
3. Select Slightly Green Bananas Instead of Very Ripe Bananas: Bananas that are slightly green will offer higher resistant starch compared to overripe bananas. Resistant starch functions like a prebiotic that helps feed healthy gut bacteria. They also improve digestion, enhance gut balance, and helps maintain stable energy levels. Dr Sethi said, "more resistant starch=feeds good gut bacteria without spiking blood sugar."
4. Replace Diet Sodas With Lemon Water: Diet sodas may have artificial sweeteners that may harm gut bacteria in some individuals. Swapping sugary or artificially sweetened drinks with water infused with lemon can enhance hydration without excess additives. Hydration plays crucial role in maintaining healthy digestion and supporting healthy and regular bowel movements.
Saurabh Sethi said, "artificial sweeteners disrupt your microbiome in ways we are still discovering."
5. Replace Processed Deli Meat With Fresh Protein Sources: The highly processed deli meats may contain increased levels of sodium, preservatives, and additives that may not support your long-term gut health. Instead, you may select some fresh protein options like grilled chicken, fatty fish, tofu, paneer, turkey, and eggs. These protein-rich foods can offer crucial nutrients while being less processed.
The AIIMS-trained doctor said, "preservatives+additives disrupt gut balance and increase inflammation.
It is significant to make gradual dietary improvements as it is not only easier but more sustainable also when compared with extreme diet changes. Over a period of time, these small habits may improve digestion, support healthy gut bacteria, reduce bloating, enhance energy levels, and support overall health and wellness. It is worth noting that gut health may differ between individuals and no single food guarantees perfect digestion. Balanced nutrition, effective hydration, adequate sleep, and strong stress management can contribute to a healthier gut.
Simple food swaps like choosing whole grain sourdough, plain fermented dairy products, slightly green bananas, water with lemon, and fresh protein sources may help support better gut health naturally. Small daily changes can gradually make a meaningful difference in digestion and overall wellness over time.
FAQs
What are the best food swaps recommended for better gut health?
The article recommends five simple swaps: replacing white bread with whole grain sourdough, flavoured yogurt with plain kefir, Greek yogurt, or dahi, very ripe bananas with slightly green bananas, diet sodas with lemon water, and processed deli meats with fresh protein sources like grilled chicken, fish, tofu, or eggs. These swaps support digestion and beneficial gut bacteria.
How do these healthy food swaps improve digestion?
Healthy swaps improve digestion by increasing fiber intake, reducing added sugars and artificial additives, and providing beneficial probiotics and prebiotics. For example, sourdough’s fermentation enhances nutrient absorption, and resistant starch in slightly green bananas feeds good gut bacteria without spiking blood sugar, all contributing to better gut microbiome balance.
Which foods should be avoided to maintain good gut health?
Processed foods like white bread, flavoured yogurts with added sugars, diet sodas containing artificial sweeteners, and processed deli meats with preservatives and additives should be limited, as they can disrupt gut bacteria balance, increase inflammation, and negatively affect digestion and overall gut health.
Can gut-friendly foods help reduce bloating and improve energy levels?
Yes. Gut-friendly foods like whole grain sourdough, plain fermented dairy, and resistant starch-rich bananas nourish beneficial bacteria, which can reduce digestive discomfort such as bloating. Additionally, improved gut balance supports better nutrient absorption and stable energy levels over time, as highlighted by Dr. Saurabh Sethi.
How long does it take to see improvements in gut health through diet changes?
Improvements from small food swaps can be gradual and vary by individual. Consistently making gut-friendly dietary changes over a period of time can lead to noticeable benefits in digestion, energy, and gut bacteria balance. Combined with hydration, sleep, and stress management, these habits promote sustainable gut health.
