She offered her top tips for combating any issues people may have going on in their guts, revealing what foods they should and shouldn't be eliminating from their diets.
Dr Jenkins recommended people consume a range of plant-based foods that are high in fibre while avoiding processed foods that are high in fat and sugar "as much as possible".
Dietary fibre is an indigestible food component that acts as a prebiotic.
According to the NHS, Government guidelines say people's intake of dietary fibre should be around 30g a day, as part of a healthy balanced diet.
The expert noted that generally people eat around 20g per day, so encouraged further intake by eating specific foods.
She suggested adding beans, pulses, wholegrains, fruit, and vegetables to a person's diet to boost their intake.
For those people wanting to lose weight quickly, she advised: "Emphasise bananas, onions, garlic, soybeans, artichokes.
"And if you are short of eating your 5-a-day of fruit and vegetables, plus on a diet, then bridge those dietary gaps with a multivitamin and multi-mineral supplement."
