Tea is a beloved beverage worldwide, celebrated for its soothing qualities, variety of flavours, and health benefits. However, for some tea drinkers, sipping their favourite brew can come with an unexpected downside: a feeling of nausea.
The culprit? most likely to be Tannins.
Tannins are naturally occurring compounds found in many plants, including tea leaves (black, green, oolong, white tea all contain some level of tannins). They belong to a group of polyphenols known for their astringent properties, which give tea its characteristic slightly bitter and dry taste. While tannins contribute to the complexity and depth of tea’s flavour, they can also interact with your digestive system in ways that may cause discomfort.
Here’s why tannins in tea might make you feel sick:
-
Irritation of the Stomach Lining
Tannins are astringent, meaning they bind to proteins and other compounds and can increase the acidity in the stomach. When consumed on an empty stomach, tannins can interact with the lining of your stomach, leading to irritation. This can cause symptoms like nausea, especially in people with sensitive stomachs.
-
Reduced Nutrient Absorption
Tannins can bind to dietary iron and other nutrients, reducing their absorption. This effect is most significant with non-heme iron, the type found in plant-based foods. While this doesn’t directly cause nausea, it can exacerbate existing deficiencies that might lead to feeling unwell.
-
Over-Brewing Intensifies the Effect
The longer you steep tea, the more tannins are released into the water. Over-brewed tea often tastes overly bitter and may have a higher tannin content, increasing the likelihood of discomfort.
How to Enjoy Tea Without Feeling Sick
If the tannins in tea leaves you feeling queasy, try these tips:
- Drink Tea with Food: Consuming tea alongside a meal or snack can buffer the stomach from tannins and reduce irritation.
- Add Milk or Lemon: Milk proteins bind to tannins, neutralizing their astringency. Lemon can alter the pH, potentially mitigating nausea.
- Choose Low-Tannin Teas: Green and white teas often have lower tannin levels than black teas, especially when steeped lightly. Herbal teas are another excellent alternative, as many are tannin-free.
- Mind Your Steeping Time: Follow the recommended steeping time to avoid over-extraction of tannins.
Tea is a wonderful addition to a healthy lifestyle, but for those sensitive to tannins, small adjustments can make all the difference. By understanding how tannins interact with your body, you can enjoy your cup of tea without discomfort.
