While it’s okay to have one or two cups of coffee, taking a pot of coffee every day can be detrimental to your health. Generally speaking, one once cup of coffee gives about 95mg of caffeine – this will vary in different commercial coffee brands. Depending on what you take, you should expect the caffeine levels to be somewhere between 0-500 mg. To reap maximum benefits, you should consume 300 mg of caffeine every day. If you enjoy a single cup of coffee a day, you’ll have nothing to worry about. Let’s get these figures straight.
Learn How Many mg of Caffeine in a Cup of Coffee
Most coffee lovers in the U.S and Europe enjoy brewed coffee. This is basically pouring hot water over ground coffee beans. One cup of brewed coffee (8oz.) contains 95 mg of caffeine on average. Not to mention, this could go as high as 185 mg. To get the recommended 200-300 mg of caffeine per day, you should consume about three cups of brewed coffee.
In those trying mornings, a shot of espresso coffee can be a real eye-opener. Well, it will depend on the caffeine content on your cup of coffee. A shot of espresso contains 63mg of caffeine. This is far much higher than the regular coffee which averages 14-16 mg of caffeine per ounce. It also means a double shot of espresso will give 125mg of caffeine. Realistically, espresso coffee has more caffeine. The brewing method will affect the caffeine content.
Note: The caffeine count will depend on the type of bean used and the method of preparation. Other factors that make the difference in the caffeine levels of espresso include:
The ideal water temperature for brewing espresso is 95-105 degrees Celsius. Because the temperature is going to make a big difference in the caffeine content, you may want to maintain at the recommended level. Don’t forget to use high quality espresso maker.
The grind size will determine how quickly your espresso shot will be extracted. When the grid is too coarse, there will be an under extraction and when it’s too fine, you’ll get an over-extraction. If you want to get more caffeine, you’ll use more ground coffee. You can use espresso machine for grinding.
Caffeine is released during the first minute of extraction, so you may want to brew your espresso shot within 20-30 seconds.
Instant coffee is prepared by grinding coffee beans and placing in hot water solution. One teaspoon of instant coffee contains 57 mg of caffeine irrespective of the water or milk. It’s worth mentioning that the strength of flavor will depend on the amount of coffee powder mixed with water. In some cases, instant coffee may contain less caffeine than brewed coffee based on the coffee beans and the brewing method used.
This coffee is prepared by pouring hot water over the coffee beans (ground) in a filter. It’s a common way of making coffee in the UK. One mug will give about 95-115 mg of caffeine.
Latte and cappuccinos
Over the years, latte coffee has become one of the popular drinks around the globe. A great latte starts with finely ground coffee beans. One cup of latte (8oz.) contains 175 mg of caffeine. Cappuccinos are made either as single/double shot and then milk is added. Although milk does not contain caffeine, you’ll find that some of these drinks will taste stronger than others.
While most people believe that decaffeinated coffee is 100% caffeine free, this is far from the truth. So, how many caffeine in a cup of coffee? Well, one cup of decaffeinated coffee contains about 7 mg of caffeine. Obviously, the caffeine content will depend on the method of decaffeination and the serving method.
Factors that affect caffeine in your coffee
As the brewing process starts, the type of coffee beans you use will determine the end results. The different varieties of coffee will give the final concentration. It’s scientifically proven that coffee from high altitudes tends to have less caffeine. Arabica and Robusta are the two common coffee beans. Arabica is always considered to be of premium quality. It’s good to note that the brewing and roasting process will make the whole difference.
The finest grinds will give the highest concentration of coffee. To put it succinctly, the way the coffee beans are ground will have a significant impact on the caffeine content.
If you want to know the exact amount of caffeine used, you should pay close attention to the size of your coffee cup. Most high-end coffee shops are known for their notoriously large cup sizes (Up to 25oz.). This is about 2-3 times that of standard coffee cups. Believe it or not, the caffeine content in your coffee will also be determined by whether you use lighter or darker roasts.
Caffeine levels in commercial brands
It’s scientifically proven that some commercial coffee brands have higher caffeine content compared to the regular home-brewed coffee. To some, it’s all about the way you prepare the coffee. So, how many mg of caffeine in a cup of coffee? Let’s look at some of the high-end brands out there.
Starbucks is arguably the most famous coffee chain in the industry. One shot of espresso contains 75 mg of caffeine while larger drinks (up to 3 shots) may contain up to 225 mg of caffeine. This includes cappuccinos, lattes, Americanos, and macchiato. The decaffeinated coffee contains about 15-35 mg of caffeine depending on the cup size. Of course, the caffeine content will vary in both caffeinated and decaffeinated coffee.
The standard K-Cup coffee pods will have about 130 mg of caffeine per cup while lighter roasts contain more caffeine than darker roasts. According to Starbucks, the caffeine content will vary based on the brewing equipment and coffee grounds used. This beverage is of consistently high quality regardless of the time of the day or locale.
McDonald’s is a popular coffee in McDonald’s restaurants. The caffeine content will vary depending on the roasting method, coffee blend, and coffee variety. A small cup contains 109 mg while a large cup contains up to 180 mg of caffeine. Their decaffeinated drinks contain 8-14 mg of caffeine depending on size. Recent studies have revealed that Starbucks coffee has twice much caffeine as McDonald.
It started in the 1950s and then grew into a worldwide franchise comprising of over 10,000 coffee shops. A recent test revealed one cup of Dunkin Donuts coffee contains 218 mg of caffeine. Their decaffeinated coffee contained 74 mg of caffeine which is almost the same as an espresso shot. The caffeine content is lower compared to that of Starbucks.
What happens if you take too much caffeine?
According to modern science, the recommended amount of caffeine is 400 mg a day – healthy for adults. Pregnant women should limit their intake to 200 mg a day while adolescents should not take more than 100 mg a day. However, what constitutes a safe amount is still a work in progress. A growing body of evidence suggests that the average half-life of caffeine is about 1.5 to 9 hours. Babies are also likely to suffer from caffeine overdose when breast milk contains an excessive amount of caffeine.
While caffeine consumption may help to boost your mood and physical performance, this happens when consumed in low amounts. Just like drugs, taking too much can have serious side effects. Before we dive into this, let’s look at the symptoms of caffeine overdose. They include;
- Increased thirst
- A Headache
Here are some red flags that you may be consuming too much caffeine.
1. Anxiety and nervousness
Anxiety is the body’s natural response to situations as threatening or worrisome. Extreme intakes of coffee 1000mg or more per day may cause jitteriness and nervousness. Since caffeine stimulates the fight or flight response, it can trigger an anxiety attack. If you notice you’re feeling nervous, it’s probably a good idea if you cut on your caffeine intake. You can also keep anxiety at bay by delaying the first cup – you’ll be surprised how your body will manage the energy levels.
2. Cause insomnia
It’s estimated that more than 50 million Americans suffer from insomnia. And the reasons are many too much work, web surfing, and TV watching. The main culprit to blame is caffeine. It boosts adrenaline production interfering with the wake sleep-cycle. This happens very on fast-in for about 15 minutes. With the coffee shop just around the street corner, it can be tempting to go for a few cups to stay alert. But, did you know it takes about 6 hours to eliminate caffeine from our bodies? There is no doubt that coffee will cause sleep problems if it’s taken late into the night. To restore the normal wake sleep-cycle, you may want to cut on your caffeine intake.
3. Digestive problems
Caffeine can stimulate the digestive tract leading to nausea, diarrhea, and stomach upset. For many years, people have linked stomach ulcers with too much caffeine but there is no conclusive study on this area. Although small amounts may cause gut motility, it can also cause GERD. Note; coffee is acidic which may irritate the lining of the stomach. To be on the safe side, you may want to take coffee in moderation.
4. Can cause high blood pressure
While it’s still unclear how caffeine raises blood pressure, people who take caffeinated beverages tend to have high blood pressure. There are two schools of thought on this issue. Some researchers believe that caffeine makes the adrenal glands release more caffeine. Others think that caffeine keeps the arteries widened.
If you’re concerned about your body’s blood pressure, ask your doctor whether you should stop drinking caffeinated beverages. Be sure to cut the intake gradually to avoid withdrawal headaches. Keep in mind that drinking in moderation (200mg a day) will keep your blood pressure at stable levels.
5. May cause muscle breakdown
High caffeine intake can cause Rhabdomyolysis, a condition associated with damaged muscle fibers. To reduce the risk of muscle breakdown, you should not consume more than 250mg of caffeine a day.
To reap the benefits of coffee, you must take in moderation. It was recently revealed that drinking two cups of coffee can have remarkable benefits to your health. Unlike other caffeinated beverages, coffee gives endless benefits. It prevents Alzheimer’s disease, reduces type-2 diabetes, supplies the body with antioxidants, and more.
How to maximize benefits while minimizing the harm of caffeine
A delicious cup of coffee perks you up and offers an array of health benefits. It’s unfortunate that most of us unintentionally hinder the true benefits of coffee. Here are some essential tips to ensure you get the most nutritional value out of every cup of coffee.
Don’t overdose on coffee
As mentioned above, too much coffee can wreak havoc your health. The truth is, drinking too much won’t increase the benefits. You can still realize the health perk with one or two cups of coffee. This is an essential tip to people struggling with diabetes, anxiety, and high blood pressure.
Don’t use caffeine every day
While coffee floods your body with antioxidants, calms stress, and repairs your DNA, it’s always important that you take some breaks. If you’re a true coffee lover, you should avoid taking this healthy drink the first thing in the morning. Throwing yourself a few cups of coffee when you wake up is not going to increase your energy levels.
A few minutes when we wake up our bodies produce high levels of cortisol so drinking coffee will not give extra energy. It’s prudent that you give yourself the natural boost between 10 am and 12 pm. Only take if you have to but limit yourself to one cup a day. And if you’re hoping to consume less caffeine, make sure you reach for the dark roast.
Drink your coffee within 20 minutes
Do you find yourself in the vicious cycle of heating your coffee every time? Any coffee that sits around increases acidity which may cause indigestion. To get all the benefits, it’s necessary that you take your coffee while it’s still hot – within 20 minutes.
Store coffee in an airtight container
Always store your coffee beans in an airtight container. Why? The levels of free radicals tend to increase when exposed in air. A cool dry place will ensure the antioxidants stay in place.
Try alternatives to caffeine
Unprocessed chocolate has the same compounds as those found in caffeine. It stimulates blood flow giving you more energy and promoting alertness.
Use coffee as a beverage, not a desert
There is nothing wrong if you want to add some sweetness to your coffee, but you shouldn’t turn this into a sugary treat. You can add milk and cream without affecting the health perks.
How caffeine works in the body
The main role of caffeine is to stimulate the nervous system. Once you take coffee, it blocks adenosine, a neurochemical that increases in the body making you feel sleepy and less alert. Simply put, caffeine mimics the presence of adenosine. Secondly, it increases the production of dopamine which activates the pressure parts of the brain. Finally, it suppresses melatonin hormone which regulates the sleep-wake cycle. For caffeine boost to kick in, you need 15-25 minutes.
Caffeine intake during pregnancy
If you’re pregnant, you’ll limit your coffee intake to 200-300mg a day. While there are different opinions on this area, you should visit your doctor to help you make a healthy choice for your baby. Pregnant women who are used to taking high levels of caffeine can deliver babies with low weight. Caffeine is a stimulant which may have a negative effect on your heart rate and blood pressure levels. Just like other drinks, it crosses the placenta of the babies which can interfere with metabolism.
If you rely on a delicious cup of coffee to keep you awake, you’re not alone. Caffeine is used by millions of people to improve concentration and focus. To be a savvy caffeine consumer, inquire about the specific sources of caffeine. If in doubt, order the small drip coffee. But why do you need to know how much caffeine is in your coffee?
Well, this will help you track how much coffee you’ve consumed in a day – no more guesswork. If you go beyond the caffeine limit, you’ll experience the negative effects. Remember, people will react differently to caffeine based on age, fitness level, and tolerance.
