New Delhi: When it comes to maintaining good gut health, adding fibre-rich and nutrient-dense foods to your diet is important, but limiting certain highly processed foods may also help support digestion. Gastroenterologist Dr Saurabh Sethi has highlighted five foods he rarely eats because they may contribute to bloating, digestive discomfort and an unhealthy gut microbiome.
1. Flavoured oatmeal packets
Flavoured oatmeal may appear to be a healthy breakfast option because it contains oats, but some packaged varieties can contain significant amounts of added sugar.
Dr Sethi recommends choosing plain old-fashioned or steel-cut oats instead. Fresh berries, chia seeds and a small amount of honey can be added for flavour and extra fibre.
2. Packaged fruit juice
Fruit juice may provide vitamins, but removing much of the fruit’s natural fibre can make it easier to consume large amounts of sugar quickly.
According to Dr Sethi, a 12-ounce serving can contain around 8–10 teaspoons of sugar. Choosing whole fruits instead can provide fibre that helps slow sugar absorption and supports beneficial gut bacteria.
3. Flavoured yoghurt
Flavoured yoghurt can contain considerably more added sugar than plain yoghurt. Dr Sethi notes that some varieties contain around 15–19 grams of added sugar per serving.
Plain yoghurt can be paired with fresh fruit, nuts or seeds for a more nutrient-dense option. People who tolerate dairy well may also benefit from the naturally occurring live cultures found in some yoghurts.
4. Deli meats and hot dogs
Processed meats such as deli meats and hot dogs are another category Dr Sethi limits. They can contain high amounts of sodium, saturated fat and preservatives.
Regular consumption of processed meat has also been associated with an increased risk of colorectal cancer. Reducing intake and choosing less processed protein sources can therefore be a useful dietary habit.
5. Instant ramen
Instant ramen is convenient, but many varieties are high in sodium and made primarily with refined flour. A single packet can contain a substantial portion of the recommended daily sodium intake.
The noodles also generally provide little fibre. For a more gut-friendly meal, adding vegetables, eggs, beans or other fibre-rich ingredients can improve its nutritional value.
The bigger picture for gut health
Dr Sethi’s recommendations highlight a broader principle: gut health is influenced not just by what you add to your diet, but also by how frequently you consume highly processed, sugary or low-fibre foods.
Whole grains, vegetables, fruits, legumes, nuts and seeds can provide the fibre and diverse nutrients that support a healthy gut microbiome. At the same time, individual responses vary, so a food that causes bloating in one person may not cause symptoms in another.
These foods do not necessarily need to be eliminated completely. Limiting highly processed and high-sugar options and choosing minimally processed alternatives more often can be a practical approach to supporting digestion and overall health.
