Do you really know how much caffeine you're putting in your body every day?

If you’ve ever had the jitters because you haven’t had your 10am cup of coffee, you’ll know just how addictive caffeine can be.

But it’s not just coffee that’s behind your caffeine addiction.

According to a recent study by the Journal of Caffeine Research, caffeine is added into a variety of foods and drinks you’ve never thought about including: Bottled water, biscuits, chewing gum and even yoghurt!

That’s shocking when you consider just how dangerous too much caffeine can be for your health.

Why aren’t health institutes stricter with caffeine regulations?

They’re starting to be.

In fact, last year, “the FDA posted several warnings about illness and deaths related to the consumption of energy drinks that contain large amounts of caffeine,” reports Yahoo Shine.

But how much caffeine is too much?

According to Consumer Reports, the daily amount of caffeine consumed for a healthy adult shouldn’t exceed 400mg.

If you exceed this, you run the risk of harmful caffeine intoxication.

Just how dangerous is caffeine intoxication?

The World Health Organisation actually recognises caffeine intoxication as a medical condition, says Dr Marilyn Glenville. “Symptoms include nervousness, anxiety, restlessness, insomnia, upset stomachs, tremors and rapid heartbeat”.

It’s the last symptom that should concern you.

After all, “two known triggers of the heart rhythm disorder supraventricular tachycardia (SVT) are caffeine and alcohol”. SVTs can make your heart beat up to 160 beats a minutes. So if you suffer from low blood pressure, chest pain or a failing heart, adding SVTs to your health issues could prove fatal.

Bottom line: Limit your daily caffeine intake by checking the labels of things you buy. If you understand how much caffeine you’re ingesting, you’ll be able to ensure you don’t go over the 400mg limit.
