For digestive problems

Discomfort after eating, constipation or an urgency to go to the loo can suggest a gut bacteria imbalance.

“The microbes that live in our digestive tract require fibre-rich foods,” says registered dietician Lola Biggs, for Together Health.

“Eating a wide range of varied fruits and vegetables and whole grains are needed to assist our colon’s function however, if your diet is low in fibre, introduce this gradually. Fermented foods can also play a key role – think kimchi, kombucha and sauerkraut.”

Consider a supplement such as Together Health’s Multibiotic Microbiome Support Capsules (£14.99, Holland and Barrett).
