Drinking Matcha May Have an Unexpected Side Effect, Health Experts Say

Drinking Matcha Could Impact Iron Absorption, Health Experts Warn

Health experts have recently raised concerns about the potential impact of drinking matcha on iron absorption in the body. Matcha, a powdered form of green tea popular for its numerous health benefits, may contain tannins that could interfere with the absorption of iron. As a result, experts are now sharing tips on how to enjoy matcha safely without compromising iron levels.

Matcha has a long-standing tradition in Japan, where it is whisked in hot water to create a frothy beverage. Over the years, it has gained global popularity for its antioxidant properties and amino acids. However, the increasing demand for matcha has led to warnings about its potential side effects, particularly concerning iron deficiency.

Registered dietitian Sarah Martel highlighted that tannins found in matcha can interact with iron absorption in the body. Tannins, a polyphenol compound present in various foods like tea, wine, and nuts, can bind to non-heme iron from plant-based sources, hindering its absorption. While a single intake of matcha may not lead to iron deficiency, frequent consumption alongside iron-rich meals could pose a risk, especially for vulnerable groups.

Individuals such as pregnant women, vegans, vegetarians, and young people, who rely on plant-based non-heme iron sources, may be more susceptible to iron absorption issues when consuming matcha regularly. To mitigate this risk, health experts suggest waiting at least an hour after drinking matcha before consuming iron-rich foods or supplements. Moderation is key, with one cup of matcha per day recommended for individuals with iron concerns.

Despite the potential impact on iron levels, matcha offers various health benefits. The amino acid l-theanine present in matcha is known for its calming effects when combined with natural caffeine content, providing an energy boost without coffee-related jitters. Additionally, factors like matcha grade and preparation method can influence tannin levels in the beverage.

Jennifer Lee, a registered dietitian and assistant professor, emphasised the importance of diversifying iron sources in one’s diet to offset any potential interference caused by matcha consumption. Leafy greens, tofu, and seeds are among the recommended iron-rich foods that can help maintain adequate iron levels while enjoying matcha in moderation.

While enjoying matcha, individuals are advised to be mindful of their overall iron intake and potential risk factors for iron deficiency. By incorporating balanced nutrition and being conscious of factors like tannin content, matcha enthusiasts can continue to savour their favourite tea while prioritising their iron health.

In conclusion, the popularity of matcha as a health beverage has raised awareness of its potential impact on iron absorption in the body. Health experts stress the importance of consuming matcha in moderation and balancing iron intake through a varied diet. By following these guidelines, matcha drinkers can continue to enjoy their favourite beverage while safeguarding their iron levels.
