We often forget that caffeine doesn’t just mean coffee. Though often associated as the main source of fuel for those early risers, caffeine can be found in all different food and beverage sources that may be unknown by some. Caffeine can be found in energy drinks, soda, tea, chocolate, and more.
Caffeine is often consumed as a way to boost energy levels, and effects can last from six to twelve hours after consumption. Peak performance of caffeine occurs after one hour of consuming the substance. The Food and Drug Administration (FDA) recommends that you should consume no more than 400 mg of caffeine a day. This is equivalent to about 4 cups of coffee a day. Refer to the table on the following page to review typical caffeine levels of popular food and beverage items. The American Heart Association suggests that moderate coffee drinking, 200mg or less, has less heart related risk factors.
Side effects of caffeine include
1. Restlessness
2. Dehydration
3. Dizziness
4. Shakiness
5. Rapid heart rate
Avoid caffeine intake When:
1. You are taking certain medications – it can
interact with the drug
2. You have trouble sleeping – try to consume
caffeine no sooner than ten to twelve hours before you are going to sleep
3. You are prone to stomach ulcers
4. You suffer from migraines or high blood pressure
5. You are pregnant
Trivia:
Is caffeine withdrawal real?
Yes, when you have caffeine regularly for a
long period of time, it can cause a physical dependence and you can experience
withdrawal without it = headaches, irritability, difficulty concentrating.
Be MINDFUL
of your caffeine intake! You don’t have to stop drinking caffeine but make sure
to be aware of how much you are drinking, what food or drinks contain caffeine, and not
to exceed recommended daily intakes.
