The leader Andrés Guacurariknown as “Andresito”promoted the cultivation of yerba mate in Misiones during the 19th century. With a legacy that transcends generations, mate is not only a tradition but also a symbol of history, which promotes unity and friendship. However, excessive consumption in summer can have unwanted consequences for health.
Whether bitter, sweet, hot or tereré, mate is much more than a drink; It is also an ally for well-being. Yerba mate is rich in antioxidants, vitamins of group B and C and minerals such as potassium, magnesium and iron. But doctors warn that excessive consumption at high temperatures can cause adverse effects such as dehydration, insomnia or gastric irritation.
“Its low calorie and sodium content makes it an ideal option for those looking for a balanced diet. It acts as a powerful diuretic and natural antioxidant that helps combat fluid retention and constipation. It is a source of group B vitamins, essential for the functioning of the body, vitamins C that help the immune system and minerals such as potassium, calcium and iron. Likewise, its xanthines stimulate the central nervous system, improving concentration and energy levels. In addition, it stands out for its satiating function, being an appetite suppressant,” he highlighted. Ana Alvarez Tartaglia, Graduate in Nutrition from Boreal Salud (MP 1316).

However, some key disadvantages should be considered. “Its diuretic effect can lead to dehydration if consumed in excess. Drinking it at very high temperatures can damage the mucosa of the mouth and pharynx. In excess, it can cause insomnia, anxiety and palpitations due to its caffeine content. It can reduce the absorption of iron, affecting people with anemia and can cause gastric irritation in people with gastritis or other digestive conditions,” the specialist explained.
Excessive consumption of mate can trigger various side effects, so it is essential to identify when this limit is reached. If combined with other stimulants, such as coffee or tea, the tolerable amount of mate decreases significantly. Some signs of overconsumption include trouble sleeping, feeling nervous, digestive discomfort, and palpitations.

“It should be emphasized that there are population groups that must limit or avoid their intake. Pregnant and lactating women can consume mate, but in moderation, due to its caffeine content. People with anemia should avoid it during meals so as not to interfere with iron absorption. Those with gastritis or other digestive conditions should refrain, as it may aggravate symptoms. Likewise, those who take medication for diseases such as depression or Parkinson’s could experience adverse interactions,” they added from Boreal Salud.
In high summer temperatures it is essential to maintain adequate hydration with water and avoid replacing it with mate. However, in balance, mate remains a healthy and representative tradition of Argentine culture.
