Caffeine is one of the most used drugs throughout the world. Whether it’s ingested through tea, coffee, or even soft drinks, most of us drink caffeine in some form of another. While we enjoy our caffeinated beverages, however, it’s worth considering that caffeine is a stimulant and that drinking too much can be potentially problematic.

As with many things in life, there are many theories and recommendations on caffeine and how much is healthy. Some even recommend swapping coffee for other beverages to minimize consumption. But should you really swap coffee for tea?

Here is what you need to know about your caffeine intake.

Pros and Cons of Caffeine

Caffeine has many benefits, but it also has some drawbacks. These are the most significant pros and cons:

Pros: In addition to giving you that little extra energy, caffeine also has a host of other potential benefits. For instance, studies show that caffeine increases memory, improves hair growth, and even decreases chronic inflammation. Furthermore, caffeine may be protective against various diseases, including Alzheimer’s, while also reducing weight gain. Another study even shows that a moderate amount of caffeine intake can help strengthen heart muscle cells.  

Cons: Meanwhile, there are also drawbacks, and even dangers, in drinking too much caffeine. Of course, we know that multiple cups of coffee before bed can cause insomnia. However, overdoing your caffeine intake can also cause anxiety, upset stomach, headaches, and may even cause temporary hand tremors.

Side Effects and Long-Term Risks of Drinking Caffeine

Long-term abuse of caffeine may lead to high blood pressure, brittle bones, and an increased risk of heart attack among young people. Furthermore, excess caffeine may decrease fertility and even lead to miscarriage in women who are already pregnant.

While the short term and long-term drawbacks of caffeine sound scary, it is important to remember that these occur from consuming the substance in extremely high doses. A single cup of coffee before bed may cause some insomnia, but it won’t cause other problems unless you happen to have a caffeine allergy. With coffee, just as with most other things in life, moderation is key.

How Much Caffeine Should We Be Consuming Daily

How Much Caffeine Should We Be Consuming Daily

According to health professionals, you should be consuming up to 400 milligrams of caffeine a day. This is equivalent to about four cups of coffee, approximately two energy drinks, or ten cans of caffeinated soda.

It would be best if you also kept in mind that 400 milligrams are the maximum amount of caffeine that is considered healthy and that you can consume less while still reaping all of the wonderful benefits of caffeine.

How Much Caffeine in Tea

Most people count their cups of coffee and even their energy drinks for their caffeine intake, but many forget to consider tea. Like coffee, tea, including green tea, is a popular source of caffeine. In case you’re wondering how much caffeine in a cup of green tea or how much caffeine is in black tea, here is a quick rundown.

Caffeine in Black Tea

With an average of 47 milligrams per cup, caffeine in black tea can definitely help give you a bit of an energy boost to help you start your day. This is less than the average cup of coffee, which contains about 95 milligrams of caffeine.

Caffeine in Green Tea

A lot of people assume that there is no caffeine in green tea, and they aren’t’ entirely correct.  The question of does green tea have caffeine in it depends on the type of green tea in question. Some types of green tea are considered decaf green tea, but don’t let the name fool you because decaf green tea still has about 20-30 mg of caffeine.

With non-decaf brands, the green tea caffeine content can average between 40-50 mg per cup, which is just a little bit less than black tea.

Mixed and Herbal Teas

Mixed and herbal teas may have some caffeine content;  however, these can vary by tea blend. For instance, Earl Grey has 95-200 mg of caffeine per cup, while specific herbal tea blends have 24-40 mg per cup. For most accurate caffeine content for mixed and herbal teas, you should check the box, or take a moment to look up the specific blend online.

Other Caffeinated Beverages

In addition to tea and coffee, caffeine can be found in sodas and energy drinks. A typical can of soda contains 40 mg of caffeine, while many energy drinks contain about 200 mg. Of course, you should always check the bottle before you consume if you are carefully monitoring your caffeine intake.
