Is caffeine bad for your heart???? Bad for running????

Coffee is so good for you. It's got what you crave. Tons of vitamins and antioxidants and electrolytes. It is kind of like Brawndo.

You may find some of that helpful, though a lot of it is on testing and the NCAA. Drinking a LOT of caffeine may cause heart problems (like it not working anymore). But that's an absurd amount, and it is very rare. Here's a guy who almost died after drinking 8 cans of an energy drink (probably red bull or monster):

Though he was also a smoker, and could have had an underlying heart condition. Green tea has a very low level of caffeine in it (~30 ml/cup IIRC) but coffee has several times more. I recommend you continue to drink coffee before your morning run as needed, but eliminate coffee from your diet for the rest of your day. Keep drinking green tea though.

Different people react differently to caffeine. I can drink a whole pot of coffee after dinner and still fall asleep an hour later.

I have noticed that if I have 6 shots of espresso just before I run, my heart is pounding a little extra during the first 2 miles. After that, I don't notice a difference. I'm sure it's not a health tonic but it's not that toxic either. And as you get older you'll appreciate its laxative qualities. :)

Yeah, but was that from the caffeine in 8 Red Bulls or from having 8x the usual amount of the entire energy blend?

Teddy Roosevelt drank a gallon of coffee per day. Voltaire reportedly drank 50-72 cups per day. I doubt that a completely natural substance so widely consumed can be dangerous. Those farmers in the Andes mountains chew on coca leaves and get a good "coke high" without the negative cardiac effects because the leaf as a whole contains moderating chemicals.

It can spike your blood pressure, so if you have underlying high blood pressure your doctor might tell you to lay off the caffeine. Beyond that, I think most studies have found coffee and tea to have positive effects on that heart.

Just do what works for you. If coffee or Pepsi or Dr. Pepper gives you your morning fix before and after you run so be it. Just run.

Yes every natural substance is healthy and good for you. FYI: Chewing coca leaves does not cause problems because of dosage not "moderating chemicals". The process of making cocaine is a process of concentrating the active ingredient and snorting is much different from chewing.

Like arsenic and lead, you mean?

You don't know sarcasm when you read it? Look at who I responded to.

Let's keep going: Pork fat is a natural substance, hence in no way damaging to your health.

I had one of my best 10 mile tempos after drinking a cup of black coffee an hour before said workout.

I know that Special Forces drink coffee and tea before they go out and snatch HVT in the Afghanistan in the middle of the night. I'm sure SEALs and Rangers do too.

I am in my 30s, female, drank coffee all my life but have become very sensitive to it. Causes bad problems, including palpitations, anxiety, clammy hands, etc.

Caffeine elevates blood sugar and stress hormones and causes the body to become very acid. If you guys concern about your health checks out this chart with details

Caffeine also contains certain other compounds that affect one negatively, even decaf. I still drink some coffee (Rich Aroma by Davidoff) but not every day and always mixed with decaf. Other days I drink green tea which gives me no problems at all.

I've experienced palpitations both when swimming and running after having moderate to high amounts (for me) of caffeine. Back when I didn't drink coffee regularly, I got palpitations after chewing RunGum before swim and track meets. As a regular coffee drinker, after drinking a can of nitro cold brew every morning for two weeks or so, I got a palpitation episode while running easy, and a mild one while at rest.

However, I think this is a pretty personal thing. For me, it seems likely to be a genetic issue.

If I drink a lot of coffee, especially in the afternoon, it will give me heart palpitations. I will randomly get these anyway, but too much caffeine usually increases the chances of me experiencing one.

It is not, just how most Americans consume it comes in an unhealthy method. Black coffee is fine. Coffee loaded with creamer and sugar not so much. Soda is bad, energy drinks are worse.

My doc asks me at the end: "So any problems you want to adress?"

Me: "Well, sometimes my hands starts to shake, I do not understand it."

Doc: "Do you drink a lot of coffee?"

Me calculating; 3 in the morning and then at the office with the kitchen close to my office 3 cups x 8hrs, and then afternoon.

"About 30 cups a day."
