Matcha tea, the vibrant green powder celebrated for its antioxidant properties and energy-boosting effects, may come with unexpected health risks, according to nutritionists. While its popularity has soared among wellness enthusiasts, experts caution that excessive consumption could lead to high caffeine intake and interfere with iron absorption.
The Caffeine Concern
Unlike regular green tea, matcha contains higher levels of caffeine due to the way it's processed. A single serving can pack as much caffeine as a shot of espresso, which may cause jitters, insomnia, or increased heart rate in sensitive individuals. Nutritionists advise moderation, particularly for those with caffeine sensitivity or underlying health conditions.
Iron Absorption Issues
Another potential downside is matcha's impact on iron levels. The tea contains tannins, compounds that can bind to iron in food and reduce its absorption. This could be problematic for individuals with iron deficiency or those at risk of anaemia. Nutritionists recommend avoiding matcha around meal times to minimise this effect.
Balancing Benefits and Risks
While matcha does offer health benefits, including antioxidants called catechins, experts stress the importance of consuming it mindfully. 'It's about finding the right balance,' says one nutritionist. 'One to two cups a day is likely safe for most people, but drinking it excessively or at the wrong times could negate its benefits.'
For those concerned about caffeine or iron levels, alternatives like herbal teas or decaffeinated green tea might be preferable. As with any dietary trend, consulting a healthcare professional before making significant changes is always wise.
