This tea made from the leaves of the Ilex paraguariensis plant is traditionally consumed in parts of South America. The indigenous Guaraní people first cultivated it before European colonization. People who drink it occasionally do not suffer from diseases. But regular, long-term consumption may increase the risk of mouth, esophagus or lung cancer. This is because it contains polycyclic aromatic hydrocarbons (PAHs) which are often carcinogenic. PAHs are also found in tobacco smoke and grilled meat. More research is needed to confirm these cancer links. Those with sleep issues should avoid it after 6 pm as it can cause problems.
The average South American drinks a lot of mate daily. This may explain why esophageal cancer is a major health issue in some countries. However, there’s no definitive evidence that hot liquids alone increase cancer risk. The cancer risk this tea poses seems to be due to its PAH content. But even that may not be concerning. One study suggests the tea may have beneficial effects on cholesterol, weight loss, heart health, inflammation and cancer risk. But more research is needed.
Cancer risk
Some studies link long-term, high intake (4-8 cups daily) with increased risk of mouth, throat and lung cancers. This seems to especially be true for people who smoke. A potential cause is PAHs in both tobacco and this tea. For healthy adults, occasional consumption likely poses little risk. But some studies suggest long-term, high intake may increase chances of certain cancers.
Is yerba mate bad for heart?
This tea contains caffeine and other stimulants. Studies show drinking 1-2 liters per day for a long time may increase the risk of mouth, throat, lung, kidney and bladder cancers. This risk goes up more if you also smoke or drink alcohol regularly. The caffeine in it can also cause side effects like headache, nausea and high blood pressure in people sensitive to it.
However, studies suggest moderate amounts may have helpful effects on cholesterol, weight loss, heart health, inflammation and cancer risk. More research is needed to confirm this though.
The tea is served hot or cold. It has a higher antioxidant level than green tea. This makes it good for preventing oxidative damage. It also has a smooth, rich flavor. So if you want an energizing drink, consider trying it. But avoid drinking liters per day for years on end.
Is yerba mate hard on the liver?
This popular drink with caffeine is made from the leaves of the Ilex paraguariensis plant. It contains antioxidants, saponins, and caffeoyl derivatives. These compounds may provide health benefits like stimulating the immune system, protecting the liver, reducing anxiety, and burning fat.
However, it also contains polycyclic aromatic hydrocarbons which are carcinogens found in tobacco. Excessive consumption has been linked to increased cancer risk. The caffeine in it can also cause side effects like insomnia, upset stomach, and high blood pressure in sensitive individuals.
The levels of caffeine and theobromine determine if it breaks an intermittent fast. Small amounts may not, but large amounts or tea form likely will. Moderation is key when consuming this tea.
