Caffeine Craze: How Much Caffeine is REALLY in My Drink?

-


Have you ever walked in to class late with a Starbucks cup in your hand? Whether it’s a Pumpkin Spice Latte, cold brew, or just a regular drip coffee, you are holding one of the 400 million cups of coffee that are consumed every single day in the United States.  But how much coffee is too much… more specifically, how much caffeine is too much?

The average 8 oz cup of drip coffee contains 96 mg of caffeine. At Starbucks, however, an 8 oz cup of their popular Blonde Roast contains 180 mg of caffeine. Order a Grande (medium) and you’ll be consuming a whopping 360 mg of caffeine.  

To prevent adverse effects caused by caffeine, its recommended to keep caffeine consumption at 400 mg per day or lower. Excessive caffeine intake can cause headaches, nervousness, irritability, increased heart rate, and insomnia, making it important to be conscious of your intake. Other sources of caffeine include tea, soda, chocolate, certain medications, weight-loss pills, pre-workout, and energy shots, so your Grande coffee from Starbucks in the morning leaves very little room for additional caffeine in your day.

Caffeine is not required by the FDA to be listed on Nutrition Labels unless it is specifically added to the food or beverage – in other words, if it is not naturally found in the product. This can make it tricky to identify how much you are actually consuming. Many restaurants list caffeine content on their website, but average caffeine content of popular beverages is listed below.

Caffeine Content

Coffee, brewed

8 oz

95 mg

Coffee, Starbucks Blonde Roast

8 oz

180 mg

Coffee, Dunkin Donuts

8 oz

180 mg

Espresso

1 oz (1 shot)

40 mg

Black Tea

8 oz

47 mg

Green Tea

8 oz

25 mg

Energy Drink

16 oz (1 can)

160 mg

Starbucks Pumpkin Spice Latte

16 oz (medium)

150 mg

Starbucks Cold Brew

16 oz (medium)

205 mg

Coca Cola

1 can, 12 oz

34 mg

Coca Cola

1 bottle, 20 oz

57 mg

  

The average American consumes 2.7 cups of coffee per day. One important thing to ask yourself is – how do you define one cup? Eight ounces is defined as one cup or one serving of coffee, so a Grande (medium) Blonde Roast at Starbucks is actually two cups.

Coffee has become a staple in many college students lives. Being conscious of your caffeine intake can prevent many side effects that can occur with overconsumption. Consuming 400 mg per day or less in coffee or tea may actually provide benefits due to antioxidant effects. So, brew yourself a fresh cup and enjoy!

    I really enjoyed your post! I am recently finding myself drinking more coffee in order to get through these busy days and I have always wondered how much is too much? I know people who go through caffeine withdrawal and I knew that I didn't want to go down that road. I found your article very helpful and answered some of my questions I had. -AV

Are All Sugars Created Equal?

Are All Sugars Created Equal?  I think one of the most confusing nutrition topics for people is sugar. With so many conflicting stories out there, it’s difficult to separate the facts from the fiction. Not to mention, the types of sugars are endless. How do we know what’s best for our bodies? White or brown sugar? Cane or raw? Should we just go with Stevia instead? Is it even okay to consume artificial sweeteners? Should we avoid foods with high amounts of natural sugar in them? Each answer only seems to lead to another question!  Let’s start off with distinguishing the purpose of sugar in the first place. Do our bodies even need it? The short answer is yes! Sugars are carbohydrates (what we commonly call “carbs”), one of the three main macronutrients that our bodies need for fuel to function and survive. One of the major ways to categorize sugar is by separating the “natural” sugars from the “added” sugars. Natural sugars are, well, naturally found in foods. They give us the energy th

Do you struggle with pre and post exercise nutrition?

What should i eat before and after a workout? First things first…carbohydrates, proteins and fats are important for the body before  and after exercise. Exercising muscle preferentially uses carbohydrates from stored glycogen, but fats are also an important fuel source for energy production during exercise. Fats and carbohydrates are the two major fuel sources during exercise. Fats must be translocated and broken down from their storage form before they are used. Typically there is enough carbohydrate stored as muscle glycogen for exercise but as muscle glycogen stores decline, the skeletal muscle will then use some amino acids (basic components of all protein). More specifically, the amino acid leucine is used for energy.              It is important to consume an adequate amount of carbohydrates exercise to delay fatigue and minimize gastrointestinal distress. It is also important to consume enough fluids to prevent hypohydration. Now, lets talk about pre-exercise me
