01How Much Caffeine Is Too Much?
Good morning, everyone. I'm a graduate student, and during exam season I used to drink coffee all day. One night, my heart was racing and I couldn't sleep at all. That made me wonder: how much caffeine is too much?
Buenos días a todos. Soy estudiante de posgrado, y en época de exámenes solía tomar café todo el día. Una noche, el corazón me latía a toda velocidad y no pude dormir nada. Eso me hizo preguntarme: ¿cuánta cafeína es demasiada?
02The Official Guidance
According to the U.S. Food and Drug Administration, four hundred milligrams a day is an amount not generally associated with negative effects for most adults. That's about two to three twelve-ounce cups of coffee.
Según la Administración de Alimentos y Medicamentos de Estados Unidos, la FDA, cuatrocientos miligramos al día es una cantidad que, en general, no se asocia con efectos negativos en la mayoría de los adultos. Eso equivale a unas dos o tres tazas de café de doce onzas.

03Caffeine in Common Drinks
Here's what surprised me. The FDA says a twelve-ounce cup of brewed coffee can contain anywhere from about one hundred thirteen to two hundred forty-seven milligrams. So two cups of strong coffee could already be over the limit.
Esto es lo que me sorprendió. La FDA dice que una taza de doce onzas de café filtrado puede contener entre unos ciento trece y doscientos cuarenta y siete miligramos. Así que dos tazas de café fuerte ya podrían superar el límite.

04Why the Range Is So Wide
Why is the range so wide? Caffeine depends on the type of coffee bean, how it's brewed, and of course, the size of the cup. A large café drink can be much bigger than twelve ounces.
¿Por qué el rango es tan amplio? La cafeína depende del tipo de grano de café, de cómo se prepara y, por supuesto, del tamaño de la taza. Una bebida grande de cafetería puede ser mucho más grande que doce onzas.
05Signs You've Had Too Much
The FDA lists several signs that you may have had too much, including a fast heartbeat, trouble sleeping, feeling anxious or jittery, an upset stomach, and headaches. I had almost all of them that night.
La FDA menciona varias señales de que quizá tomaste demasiada, entre ellas el corazón acelerado, problemas para dormir, sentirte ansioso o nervioso, malestar estomacal y dolores de cabeza. Esa noche yo tuve casi todas.

06Not the Same for Everyone
It's important to remember that this guidance isn't the same for everyone. The FDA suggests that people who are pregnant, breastfeeding, or taking certain medicines talk to a doctor, and medical experts advise against energy drinks for children and teens.
Es importante recordar que esta recomendación no es igual para todos. La FDA sugiere que las personas embarazadas, que están amamantando o que toman ciertos medicamentos hablen con un médico, y los expertos médicos desaconsejan las bebidas energéticas para niños y adolescentes.

07What I Do Now
Now I keep it simple. I have two cups of coffee before noon, switch to tea in the afternoon, and keep a bottle of water on my desk while I study.
Ahora lo mantengo sencillo. Tomo dos tazas de café antes del mediodía, cambio al té por la tarde y tengo una botella de agua en mi escritorio mientras estudio.
08Conclusion
To sum up, caffeine isn't bad, but the amount matters, and cups can be very different. Know roughly how much you're having, listen to your body, and ask a doctor if you're unsure. Thank you.
En resumen, la cafeína no es mala, pero la cantidad importa, y las tazas pueden ser muy distintas. Sepan más o menos cuánto están tomando, escuchen a su cuerpo y consulten a un médico si tienen dudas. Gracias.
