Some leading experts on gut health have revealed the foods they always avoid so as not to run the risk of getting some nasty gastro issues.
While it's very often things like highly processed foods and sweets which we are told to avoid, some of these might surprise you as they could be staples of your diets.
But eating these foods can lead to some health affects like bloating, gas and even more serious health problems.
Gastroenterologist at Tufts Medical Centre, Doctor Harmony Allison, avoids something consumed by many fitness fans daily - protein bars.
She told the Huffington Post: "I never eat protein bars. They tend to be highly processed and contain lots of additives that are of unknown utility."
The doctor went onto say that more natural sources of protein such as from nuts, pumpkin seeds or Peanut Butter would be a far better alternative.
A second expert, Dr Reezwana Chowdhury, went for something very different as she always avoids steak.
The gastroenterologist at Johns Hopkins said: "Red meat and processed meat increase the risk of colon cancer and colon polyps."
Although red meat is an important source of essential vitamins and amino acids, Dr Chowdury says to aim for no more than 100 grams per day – and ideally no more than once a week.
Dr Simon C Matthews, again of Johns Hopkins and advisory board member to Vivante Health, has gone for something a little bit more mainstream.
Many doctors have been warning against fizzy drinks and this is something that Dr Matthews chooses to avoid at all costs.
He said: "While they can be easy on the way down, these drinks are linked to chronic conditions as well, such as diabetes and heart disease."
These drinks can make you bloat, as well as burp and give you a nasty bout of acid reflux.
The final food which Dr Shilpa Grover has warned against eating something which is a staple in many UK diets - white bread.
The director of the onco-gastroenterology programme in the division of gastroenterology at Brigham and Women's Hospital explained that refined grains can wreak havoc on our guts.
So, it could be an idea to steer clear of these in the supermarket, or minimise your consumption, if you want to maximise the health of your gut.
