A Harvard-trained gastroenterologist has issued a health alert to Britain's tea lovers, warning that common brewing habits could be damaging digestive systems and livers across the nation.
The Nation's Favourite Drink Under Scrutiny
With Brits consuming over 100 million cups daily according to the UK Tea & Infusions Association, and 84% of the population drinking tea every day, this warning comes at a crucial time for public health. Dr Saurabh Sethi, a board-certified gastroenterologist with 1.3 million Instagram followers, has identified seven potentially harmful tea practices that could be compromising wellbeing.
The Seven Dangerous Tea Habits
1. Drinking Tea on an Empty Stomach
Dr Sethi's first recommendation urges people to avoid sipping tea without food. The acidity and compounds like caffeine and tannins can irritate the stomach lining, potentially triggering acid reflux, nausea, and general discomfort. This practice may also cause dehydration and hinder iron absorption, particularly problematic for those with anaemia.
2. Sweetened Teas and Their Hidden Dangers
The specialist warned against regularly consuming iced teas or milk teas containing 30-40 grams of sugar per serving. This substantial sugar intake significantly increases the risk of developing conditions like non-alcoholic fatty liver disease and diabetes.
3. The Truth About 'Detox' and Slimming Teas
Despite their appealing marketing, detox or slimming teas often contain laxative components that can cause dehydration and electrolyte imbalance when consumed excessively. Dr Sethi emphasises the importance of following NHS guidance on laxatives and never exceeding recommended doses.
4. Green Tea Extract Overconsumption
While green tea itself is widely recognised as healthy, Dr Sethi issued a stark warning about over-reliance on green tea supplements. These concentrated forms have been associated with a rare but real risk of liver toxicity, despite their antioxidant benefits.
5. The Temperature Danger Zone
Many Brits pour boiling water directly onto tea bags, but Dr Sethi advises waiting until the temperature drops below 65°C. Research from a 2020 Chinese study found that regularly consuming tea hotter than this significantly increases the risk of oesophageal cancer, specifically oesophageal squamous cell carcinoma.
6. Late-Night Caffeinated Teas
Although tea contains less caffeine than coffee, drinking chai or green teas late at night can disrupt sleep patterns. Caffeine lingers in the body, potentially hindering the liver and gut's natural overnight repair processes.
7. Bubble Tea's Hidden Calories
The gastroenterologist specifically cautioned bubble tea enthusiasts about the combination of high sugar content and starchy tapioca pearls. This sugary concoction can lead to unexpected calorie intake, potentially resulting in insulin resistance and non-alcoholic fatty liver disease.
Protecting Your Health While Enjoying Tea
Dr Sethi's recommendations don't suggest abandoning tea altogether, but rather adopting smarter consumption habits. Maintaining a balanced lifestyle with nutritious food choices remains crucial for mitigating potential health risks while continuing to enjoy Britain's most beloved beverage.
