GP Dr Donald Grant has warned that common fruits such as apples, pears, and strawberries can trigger unpleasant symptoms including bloating, diarrhoea, and allergic reactions. He explained that many people have difficulty metabolising fructose, a sugar found in fruit, leading to digestive issues.
Dr Grant, Senior Clinical Advisor at The Independent Pharmacy, said: 'It's not uncommon for people to find difficulty metabolising fructose - a sugar found in fruits. This can impact people in numerous ways with symptoms including bloating, increased flatulence and even diarrhoea.' He advised those with fructose malabsorption to avoid high-fructose fruits like apples, pears, and mangoes.
In addition to digestive problems, fruits can cause allergic reactions. Dr Grant noted that apples are a common trigger for oral allergy syndrome (OAS), where the immune system reacts to fruit proteins similar to pollen. Symptoms include swelling around the lips, mouth, and tongue. Other fruits that may cause OAS include pears, plums, and cherries.
Strawberries, kiwis, and avocados are among the most common fruits to cause allergic reactions, with symptoms ranging from hives and nausea to anaphylaxis. Dr Grant emphasised that reactions can develop at any stage of life and urged people to discuss any concerns with their GP.
For those experiencing diarrhoea, Dr Grant recommended Dioralyte Sachets to replace lost fluids and restore hydration. The NHS continues to advise eating at least five portions of fruit and vegetables daily as part of a balanced diet, but individuals with symptoms should seek medical advice.
