This evidence is particularly significant as bowel cancer remains one of the leading causes of cancer-related deaths globally
Recent studies have revealed promising evidence suggesting that consuming yoghurt regularly may significantly reduce the risk of developing bowel cancer. Oncologist Professor Justin Stebbing has emphasized that yoghurt, particularly varieties containing live cultures, can lower the likelihood of developing this serious condition by up to 20%.
According to Professor Stebbing, a leading figure in biomedical sciences at Anglia Ruskin University in Cambridge, the dairy product contains beneficial bacteria called Bifidobacterium. This strain of bacteria is believed to play a crucial role in preventing the formation of tumours, ultimately reducing the risk of bowel cancer.
However, the oncologist stresses that the yoghurt consumed should contain live cultures, as not all forms of the food deliver the same protective benefits. This is due to varying fermentation processes that can lead to different levels of beneficial bacteria in the final product. These fermentation variations can make some yoghurts less effective at providing the same protective effects.
The findings are based on research conducted in February 2025, which concluded that people who consume at least two servings of yoghurt every week for 30 years have a 20% lower risk of developing bowel cancer compared to those who do not. This evidence is particularly significant as bowel cancer remains one of the leading causes of cancer-related deaths globally.
In his article for The Conversation, Professor Stebbing states, “The emerging evidence suggests that regular yoghurt consumption may have a protective effect against certain aggressive forms of bowel cancer.” He goes on to explain that the presence of Bifidobacterium can help maintain a healthy gut microbiome, which is increasingly recognized for its crucial role in preventing a range of diseases, including cancer.
The idea that food can influence cancer risk is not new, with other studies pointing to the importance of a balanced diet rich in fruits, vegetables, and whole grains in reducing cancer risks. However, this new research adds a specific food—yoghurt—with proven potential in reducing the risk of a highly prevalent form of cancer.
The Rising Threat of Irritable Bowel Syndrome (IBS) in Young Adults
While yoghurt may offer benefits for preventing bowel cancer, another digestive issue, irritable bowel syndrome (IBS), is becoming increasingly common, particularly among young adults. IBS, a gastrointestinal disorder that causes symptoms such as abdominal cramps, diarrhoea, constipation, and bloating, is affecting more individuals, particularly those aged 20 to 40. Experts attribute the rise of IBS to factors such as high stress, sedentary lifestyles, poor dietary habits, and inadequate exercise.
Bir Singh Sehrawat, Director of Gastroenterology at Marengo Asia Hospitals, Faridabad, explains that IBS is often linked to an overly sensitive colon or an irregular immune system. In recent years, young adults have become more susceptible to this condition due to their diets, which often consist of fast food that is high in fats, sugars, and artificial additives. These dietary choices disrupt the delicate balance of gut bacteria, triggering IBS symptoms.
Additionally, mental stress is a significant contributor to IBS, with anxiety and hormonal imbalances interfering with normal digestion. The hormonal changes caused by stress can lead to discomfort such as bloating and altered bowel movements, further exacerbating IBS symptoms. As the pressures of modern life continue to escalate, the number of young people facing IBS is on the rise.
While IBS itself does not increase the risk of more serious conditions like colon cancer, it can severely impact daily life. Symptoms such as bloating, abdominal cramps, diarrhoea, and constipation can cause long-term distress and discomfort. Healthcare experts are therefore emphasizing the need to recognize IBS symptoms early on and seek medical advice to manage the condition effectively.
Preventing IBS: Lifestyle Changes and Dietary Adjustments
To reduce the risk of IBS, experts recommend a few lifestyle changes. A diet rich in fibre is essential, as it can help maintain gut health and regulate bowel movements. Reducing the intake of processed and fast foods, as well as staying hydrated, can also help alleviate symptoms.
In addition to dietary changes, regular physical activity can improve digestion and reduce the stress that often contributes to IBS. Experts also advocate for stress management techniques such as yoga and meditation, which can help calm the mind and alleviate the physical symptoms of IBS.
Despite the manageable nature of IBS, healthcare professionals warn that it is important not to ignore the symptoms, as untreated IBS can lead to further complications in the digestive system. If left unchecked, IBS can affect the colon and large bowel, leading to additional discomfort and more severe gastrointestinal problems.
The findings on yoghurt’s potential to reduce bowel cancer risk provide promising insights into the role of diet in cancer prevention. However, as the incidence of IBS increases among young adults, it is crucial to address the lifestyle factors contributing to this growing issue. Regular yoghurt consumption, along with a healthy diet and stress management, may play key roles in protecting the gut and preventing both IBS and cancer.
As always, it is important to consult a healthcare provider for guidance and treatment when experiencing digestive issues, ensuring early intervention for both IBS and other gastrointestinal concerns.
