One of the increasingly common concerns among all types of consumers is metals. That's why metal-free matcha is highly valued. But let's dig a little deeper and reveal the metals in matcha that it typically contains naturally and which ones it shouldn't contain.
Metals in Matcha: Essential Nutrients and Risks to Consider
A matcha, in addition to being a drink rich in antioxidants and chlorophyll, it also naturally contains several essential metals for healthHowever, like any plant crop, it can be exposed to contaminants if it's not sourced reliably. In this article, we explain which metals are naturally present in matcha and why it's essential to choose a high-quality product.
Essential metals naturally present in matcha
Although the amount of these minerals may seem small, a daily serving of matcha (approximately 1 gram or ½ teaspoon) can contribute to the supply of key micronutrients for the body:
- Potassium: 27 mg
Helps regulate blood pressure and fluid balance in the body. - Magnesium: 2.3 mg
It participates in muscle and nerve function and in energy production. - Calcium: 4.2 mg
It is essential for bone and dental health. - Zinc: 0.062 mg
Contributes to the immune system and wound healing. - Phosphorus: 3.5 mg
Supports cellular development and energy production. - Iron: 0.17 mg
Essential for the formation of red blood cells and the transport of oxygen.
Heavy metals: a risk that should not be ignored
Matcha, like any plant, can absorb elements from the soil, including potentially toxic heavy metals. Among the most common are:
- Lead: It can be absorbed by the roots of the tea plant, especially if the soil is contaminated. Its accumulation in the body can cause neurological problems and other health disorders.
- Arsenic: Also present in some agricultural soils, it can pass into the plant and then into the matcha. Prolonged exposure to arsenic is linked to toxic effects on various organs.
How to avoid contaminated matcha?
To minimize these risks, it is important to choose matcha that meets these criteria:
- Certified origin: Choose matcha grown in regions with controlled soils and responsible agricultural practices, such as Japan (especially Kagoshima or Uji).
- Laboratory tests: Serious producers make periodic analysis to ensure that heavy metal levels are below legal and safe limits.
- Transparency: Trusted brands often share these analyses or certify their products with quality seals.
