Soda Overview: Why Do People Like it? 

Soda is one of the few drinks beloved by many people, even if it has been proven to have harmful effects. This drink is so tasty that people can look past its impact and become addicted to this drink. Some people even drink it with every meal. Soda can also be found almost everywhere. Vending machines have them. Fast-food chains offer them with their meals, and you can even find them at supermarket checkouts.

Coffee Vs. Soda (Differences Compared) 

It’s no doubt that coffee and soda are two favorite beverages that many people drink every day. They're both tasty and contain caffeine, making them addictive to many individuals. If you're wondering which is a better choice, we have listed down their differences for you.  


When people discuss soda, the last thing you’d probably hear is its acid levels. Unfortunately, it’s not the same with coffee. Coffee is infamous for being acidic. However, it has a lower pH level compared to soda. But don’t confuse pH levels and the state of being acidic with the actual acidity of the coffee. 

Acidity plays a crucial role in the taste of coffee. When coffee is in its natural state of being green, it contains a variety of both good and bad acids. Some of these acids disappear after being roasted, but some remain. The main culprits for the high acidity of coffee are chlorogenic acid and quinic acid. 

Chlorogenic acids or antioxidants are usually broken down during the roasting process. This is why many people often equate coffee beans that are darker and roasted longer with having lower acidity compared to other beans. Those chlorogenic acids that are not broken down during the process turn into quinic acid. You can usually find quinic acids in darker roasted coffee beans, and the reason for the sour sensation in your stomach after drinking coffee.  


Both soda and coffee contain caffeine, but coffee has more caffeine compared to soda. An 8-oz (237 ml) cup of brewed coffee has around 95 to165 mg of caffeine, and a 1-oz (30 ml) shot of espresso contains 47 to 64 mg of caffeine. 8-oz coffee drinks with other ingredients like latte and mocha have 63 to 126 mg of caffeine.  

Even decaf coffees contain small amounts of caffeine. A regular cup of decaf coffee will give you 2 to 5 mg of caffeine, perfect for those who are sensitive to this substance. However, you should note that the caffeine content depends on the beans’ origin, how they are processed, and the preparation methods. So, brewing coffee longer can increase the amount of caffeine in a cup.  

Compared to coffee, soda contains less caffeine. For example, an 8-oz cup of black cola soda only has around 24 to 46 mg of caffeine, while citrus-flavored sodas and root beer don’t have any caffeine in them.  

Sugar Content 

Sodas are already sweetened by sugar,  high-fructose corn syrup, or artificial sweeteners, such as sucralose or aspartame. This means that you don’t have control over how much sugar you’ll consume when you drink sodas.

On the other hand, coffee doesn’t come with sugar, and you are in charge of how much sugar you want unless you buy a pre-made coffee drink. So if you’re going to get the same amount of sugar in your coffee as in your soda, you need to add ten teaspoons of sugar. This is why even though soda has less caffeine content, it gives you more energy than a cup of coffee.  

Calorie Content 

According to the Harvard School of Public Health, an average can of sugar-sweetened soda has 150 calories.

An equal serving of coffee (12-oz) only has four calories. While diet sodas contain zero calories, it isn’t suitable for your diet, especially if you are trying to lose weight. Zero-calorie sodas make you crave other sugary drinks and food throughout the day and often contain high amounts of artificial sweeteners.  

While coffee contains fewer calories, adding sugar, cream, or syrup to it will raise the calorie count and be as high-caloric as sodas.  


Soda contains carbonation giving it the distinctive taste that many people refer to as crispy or bite. Only later in the tasting process, your tongue picks up other flavors and sugar in sodas. However, if the soda has less carbonation, the different flavors and sugars are much easier to taste.

Depending on where it comes from, how it's grown, and the brewing process, coffee can be bitter, sweet, sour, or a combination of two or all three flavors. However, the taste of coffee can easily be modified by adding sugar, coffee, or other ingredients like chocolate.  


Sodas often contain carbonated water, high fructose corn syrup (sugar), caffeine, caramel color, natural flavors, carbon dioxide, organic diol, phosphoric acid, citric acid,  Brominated vegetable oil (BVO), and many other ingredients, depending on the manufacturer. On the other hand, brewed coffee only has coffee and water, and other drinks may have milk, sugar, chocolate, syrup, caramel, and other ingredients depending on the beverage you drink.  

Health Effect 

Coffee has numerous health benefits proven by various scientific studies. For example, it can help improve brain functions such as concentration and memory and reduce the risk of certain diseases, including Alzheimer’s diseasedementiaParkinson’s diseasetype 2 diabetes, and stroke. It is also rich in antioxidants and contains small amounts of vitamins such as manganese, B2, B3, and B5.  

On the other hand, sodas may not be suitable for your health because of their high sugar contents. Consuming it in massive amounts can contribute to diabetes, weight gain, and cardiovascular conditions. According to the Centers for Disease Control and Prevention (CDC), consuming too many added sugars can lead to health problems.
