Caffeine and Its Impact on the Body

Yerba maté is often sought after due to its high caffeine content, which is known for its ability to stimulate the body and enhance mental performance. One serving of yerba maté contains approximately the same amount of caffeine as a cup of coffee, which can be advantageous for those who need a quick energy boost. However, the high caffeine content can cause negative effects of yerba maté, especially in people sensitive to this stimulant.

For individuals who are not accustomed to caffeine or consume it in larger doses, drinking yerba maté can cause unpleasant conditions such as nervousness, anxiety, irritability, or tremors. It can also result in a rapid heartbeat or sleep problems. Insomnia is one of the most common negative effects of yerba maté, especially if the beverage is consumed later in the day. This phenomenon is primarily observed in people with lower caffeine tolerance or those who drink large quantities of yerba maté.

In addition to the aforementioned issues, the caffeine in yerba maté can also contribute to dehydration. Caffeine has a diuretic effect, which means it promotes urine excretion, and if sufficient hydration is not maintained, dehydration can occur, leading to further health complications such as headaches, fatigue, or dizziness.

Potential Risk of Esophageal Cancer

One of the more serious negative effects of yerba maté, which is still under research, is the potential increased risk of esophageal cancer. Studies conducted in South America indicate that people who regularly consume yerba maté in very hot forms may be at a higher risk of developing esophageal cancer. Hot liquids passing through the esophageal lining can cause irritation and, in the long run, contribute to the development of cancerous cells.

Although there is no definitive evidence yet that yerba maté itself causes cancer, it is advisable to ensure that yerba maté is not consumed too hot. Drinking lukewarm or warm beverages can help reduce this potential risk. The impact of temperature on health is a known factor for other beverages as well, such as coffee or tea, and it's important to recognize that hot drinks can have an adverse effect on our bodies.

Toxins in Yerba Maté

Another important aspect to consider is the toxins present in yerba maté. Studies have shown that during the drying process of Ilex paraguariensis leaves, used to make yerba maté, contamination with polycyclic aromatic hydrocarbons (PAH) can occur. These substances are considered carcinogenic and are also present in cigarette smoke or polluted air. Although these are relatively small amounts, long-term consumption of yerba maté with these substances could pose a potential risk to human health.

In addition to PAH, yerba maté may also contain traces of heavy metals, such as aluminum or cadmium. These substances can have toxic effects on the human body when consumed excessively. For instance, cadmium is associated with kidney damage, and long-term exposure to high doses of heavy metals can lead to chronic health problems.

Interactions with Medications

Drinking yerba maté can also affect the efficacy of certain medications. The caffeine in yerba maté can interact with heart medications, antidepressants, or blood pressure medications. This interaction can cause undesirable effects, such as irregular heart rhythms or increased blood pressure. If you are taking medications, it's important to consult with your doctor about yerba maté consumption to avoid potential health complications.

Yerba maté is a fascinating beverage with many health benefits, but it's essential to be aware of its potential risks. The negative effects of yerba maté, such as caffeine side effects, the risk of esophageal cancer when consuming hot drinks, or the presence of toxins, cannot be ignored. As with any beverage or food, moderation is key to minimizing these risks.

If you wish to try yerba maté or regularly consume it, focus on the quality of the purchased product and ensure that yerba maté is consumed judiciously. Regular hydration, limiting the consumption of hot beverages, and moderation in the use of this stimulating drink will help you benefit from its advantages without facing its negative effects.
