We all have our guilty pleasures – a fizzy drink with pizza, a late-night burger, or a bit too much chocolate after a stressful day.
But for gastroenterologists, who spend their days studying how food affects the digestive system, there are certain things they actively avoid.
While an occasional indulgence won’t ruin your health, these gut experts tend to stay away from a few particular foods that can cause long-term issues for digestion, heart health, and overall wellbeing.

Protein Bars

Many protein bars promise a healthy boost, but gastroenterologists like Dr Harmony Allison from Tufts Medical Center prefer to skip the heavily processed versions.
They often contain artificial additives and preservatives that can upset digestion and cause bloating.
Steak
According to Dr Reezwana Chowdhury of Johns Hopkins, red meat – particularly steaks and burgers – is something she limits as much as possible.
High in saturated fat, it’s linked to a greater risk of colon issues when eaten in excess.
Hot Dogs And Processed Meats

For Dr Rabia De Latour at NYU Grossman School of Medicine, processed meats are best avoided altogether.
From bacon to cold cuts, these foods have been tied to a higher risk of colorectal cancer when eaten frequently.
Deep-Fried Fish Or Chicken
Dr Mahmoud Ghannoum, a microbiome researcher and co-founder of BIOHM, points out that fried foods aren’t just heavy – they can also disrupt gut bacteria over time.
Fried oils can contribute to inflammation and artery build-up, which may lead to more serious problems down the line.
Sugary Fizzy Drinks

Dr Simon C. Matthews of Johns Hopkins avoids sugary sodas and energy drinks.
While they’re refreshing in the moment, they can trigger bloating, reflux, and long-term issues such as diabetes and heart disease.
White Bread
Refined grains, according to Dr Shilpa Grover of Brigham and Women’s Hospital, are another no-go.
Diets high in white bread and processed grains have been linked to digestive problems like diverticulitis, while wholegrain alternatives support a healthier gut.
