Yerba mate, also known as mate, is an herbal tea native to South America. It is made by steeping the twigs and dried leaves of the Ilex paraguariensis plant in hot water. Traditionally served in a gourd and sipped through a filtered metal straw, yerba mate is known for its numerous health benefits. However, some researchers have linked smoked yerba mate to certain types of cancer. In this article, we will explore the potential risks and benefits of smoked yerba mate.
What is Yerba Mate?
Yerba mate is an herbal tea that has gained popularity in recent years. It is often consumed for its potential health benefits, including its anti-inflammatory and stimulant effects. Yerba mate contains various antioxidants and nutrients, such as xanthines, saponins, polyphenols, and caffeoyl derivatives. The caffeine present in yerba mate can increase mental focus and energy levels without the jittery effects often associated with coffee consumption. Additionally, yerba mate is believed to improve sports performance, protect against common infections, boost the immune system, and lower the risk of heart disease.
Does Smoked Yerba Mate Cause Cancer?
While yerba mate is generally considered beneficial for the body, research suggests that excessive consumption of smoked yerba mate over a prolonged period of time may be linked to certain types of cancer. Studies have shown an association between smoked yerba mate and lung, mouth, stomach, esophageal, laryngeal, and bladder cancers. This is due to the presence of polycyclic aromatic hydrocarbon (PAH), a known carcinogen also found in grilled meat and tobacco smoke. Increased exposure to PAHs can affect various systems in the body, including the immune, reproductive, and neurological systems, and can increase the risk of cancer development.
Furthermore, drinking very hot yerba mate tea, at temperatures at or above 147ºF (64ºC), is associated with a higher risk of cancer compared to drinking mate tea at cooler temperatures. Consuming liquids at higher temperatures can damage the respiratory and digestive lining, leading to potential harm.
Yerba Mate Side Effects
While yerba mate is known for its potential health benefits, consuming it in excess can lead to various side effects. Similar to coffee and other caffeine products, yerba mate tea may cause headaches, anxiety, nervousness, upset stomach, nausea and vomiting, ringing in the ears, and irregular heartbeat. It is important to consume yerba mate in moderation to avoid these side effects.
Additionally, certain individuals should take precautions when consuming yerba mate tea. Pregnant and breastfeeding women should be cautious due to the high concentration of caffeine in yerba mate, which can increase the risk of transferring caffeine to the fetus and potentially lead to complications such as miscarriage, low birth weight, and premature birth. Individuals who smoke tobacco or drink alcohol may also be at a higher risk of developing cancer when consuming yerba mate. Those with anxiety disorders or irritable bowel syndrome (IBS) should be aware that excessive consumption of yerba mate can worsen their symptoms.
Is Roasted Yerba Mate Safe?
Roasted yerba mate is a popular variation of yerba mate tea. It is made by roasting the leaves of the yerba mate plant before steeping them in hot water. Like traditional yerba mate, roasted yerba mate contains caffeine and may offer similar health benefits. However, research on the specific effects and safety of roasted yerba mate is limited.
In general, drinking yerba mate tea, including roasted yerba mate, is not linked to health problems in most adults when consumed in moderation. It is important to note that excessive consumption, especially when combined with other risk factors such as smoking or heavy alcohol consumption, may increase the risk of certain types of cancer. Pregnant women should consult with a healthcare provider before consuming yerba mate due to its caffeine content.
In conclusion, while yerba mate is known for its potential health benefits, excessive consumption of smoked yerba mate over a prolonged period of time may increase the risk of certain types of cancer. It is important to consume yerba mate in moderation and be aware of potential side effects. Pregnant women and individuals with certain health conditions should exercise caution when consuming yerba mate. As always, it is recommended to consult with a healthcare professional for personalized advice.
