Daily tea drinking boosts health but has surprising risks

Drinking tea daily can bring a range of health benefits, from protecting teeth to lowering the risk of serious diseases. Experts suggest that three to five cups a day may offer the best results—but too much could cause problems.

Tea contains powerful antioxidants that help fight damage from smoking, pollution, and excessive sun exposure. These compounds also reduce the risk of stroke and certain cancers by preventing harmful oxidation in the body. Both black and green tea can suppress bad bacteria in the gut while supporting good bacteria, aiding digestion and metabolism.

Regular tea drinkers may also develop stronger muscles and avoid gastric ulcers, thanks to its calcium content. The drink even helps heavy alcohol consumers by reducing some of the negative effects. For teeth, tea inhibits plaque formation, cutting the risk of cavities and decay.

However, drinking more than five cups a day—especially caffeinated varieties—can lead to anxiety, insomnia, and reduced iron absorption. Kenya, one of the world's top tea producers, grows around 500,000 tons annually, mainly in regions like Kericho, Nyeri, and Kiambu.

With its ability to lower heart disease risk, prevent tooth decay, and support gut health, tea remains a simple yet effective health aid. Sticking to three to five cups daily maximises benefits while avoiding potential downsides like sleep issues or nutrient loss.
