Spicy food is a staple in many Indian households, especially in states like Rajasthan, where fiery curries and chilli-rich dishes are a part of everyday meals. While spices can add flavour and even offer certain health benefits, a recent study suggests that consuming excessively spicy food over a long period may increase the risk of certain types of cancer.
A study published in the journal Frontiers in Nutrition found that people who regularly consumed large amounts of chilli peppers had a higher risk of developing gastrointestinal cancers. These include cancers of the stomach, colon, rectum, and particularly the esophagus—the food pipe that carries food from the mouth to the stomach.
The researchers analysed data from 14 separate studies involving nearly 1.1 lakh participants, including around 5,000 people diagnosed with gastrointestinal cancers. According to the findings, individuals with the highest chilli consumption had a 64% greater risk of developing gastrointestinal cancers compared to those who consumed the least amount of chilli.
One of the main concerns highlighted in the study is the possible link between excessive chilli intake and esophageal cancer. This type of cancer develops in the food pipe, and one of its early warning signs is persistent heartburn. Other symptoms may include difficulty swallowing, unexplained weight loss, chest or back pain, frequent stomach discomfort, swelling in the throat, poor digestion, and a constant feeling of illness.
The heat in chilli peppers comes from capsaicin, a naturally occurring compound responsible for their spicy taste. Capsaicin is known for its anti-inflammatory properties and has been studied for several potential health benefits. However, researchers note that consuming very high amounts of capsaicin over a prolonged period may repeatedly irritate the lining of the esophagus in some individuals.
Some earlier studies have also suggested that continuous irritation and inflammation of tissues could contribute to abnormal cell changes over time. However, scientists stress that the current evidence does not prove that spicy food directly causes cancer. More research is needed to understand the relationship and identify whether other dietary and lifestyle factors also play a role.
Experts say there is no need to eliminate spicy food completely. Instead, moderation is key. People who frequently experience acid reflux, heartburn, or persistent digestive problems after eating spicy meals should consult a healthcare professional rather than ignore the symptoms.
The study serves as a reminder that while chilli peppers can be part of a healthy diet, excessive consumption may not be suitable for everyone. Paying attention to your body's signals and maintaining a balanced diet can go a long way in supporting long-term digestive health.
