Iced Coffee or Hot Coffee: Which is Healthier?


Have you ever wondered which one is healthier between iced coffee and hot coffee? Which has the higher caffeine content to cheer up the day? Or are they actually the same? Find out the answer in this article. 

Benefits of drinking coffee for health

Regardless of how it is served, coffee itself basically contains a number of health benefits that are good for the body. 

Drinking coffee regularly is reported to reduce the risk of type 2 diabetes, heart disease, cancer, depression, and various diseases related to neurological disorders, such as a myotrophic Lateral Sclerosis (ALS) and Parkinson's. 

One report from the NIH-AARP Diet and Health Study states that drinking one cup of coffee daily can reduce the risk of premature death by 6 percent. Drinking 2-3 cups of coffee can even reduce the risk of premature death by 10 percent. 

Although it is not known what is the reason behind these health benefits, health experts believe that coffee's high content of antioxidants, polyphenols, and minerals play a major role in making it happen. 

Then, which is better: drinking iced coffee or hot coffee?

A professor of epidemiology and nutrition at the Harvard TH Chan School of Public Health, Frank Hu, MD. PhD., said that the temperature of coffee brewing has no effect on the nutritional content of coffee. When it comes to taste, of course, this all depends on the taste of each individual. 

Both a cup of hot black coffee and a glass of iced coffee are practically zero calories and have no significant nutritional value. 

A cup of black coffee and cold coffee without sugar are both devoid of carbohydrates, fat, protein, and other important macronutrients, such as calcium and fiber. The nutritional value of the two versions of this drink will only change when added flavors or sweeteners. 

If you want to compare which one has a stronger caffeine content between iced coffee and hot coffee, actually both are the same. 

The reason is, iced coffee was originally made from steeping hot water which was then added with ice cubes. However, the effects of caffeine on iced coffee will appear more quickly. 

Iced coffee is safer for people with digestive disorders

Although the effect of caffeine in cold coffee is arguably higher than warm coffee, the taste of iced coffee is not as sour as warm brewed coffee. 

The average cold coffee has a pH level of 6.31 as opposed to the hot version which contains a pH of 5.48 - on the pH scale, the lower the number the more acidic the substance is. 

The reason is, the hot water used to brew coffee will release a more concentrated acid from the coffee beans. Meanwhile, ice cubes will dilute the coffee concentrate more so that the taste is more "tame".

This means cold coffee may be a safer choice for satisfying coffee cravings for people who are sensitive to caffeine or have digestive problems, such as heartburn or acid reflux (GERD), explains Joan Salge Blake, RD, associate clinical associate at Boston University, and author of Nutrition & You, reported by Health. 

In addition, low-acid foods/drinks have been associated with a variety of health benefits, such as supporting bone health, reducing muscle mass loss, maintaining heart and memory health, to reducing the severity or incidence of hypertension and stroke, according to an article in the Journal of Environmental and Public Health.

Cold coffee doesn't make teeth yellow

Both iced coffee and hot coffee can stain teeth because they contain tannins (a type of polyphenol), the compound responsible for discoloring your teeth. But the yellow tooth effect of iced coffee is still lighter than regular coffee because it contains less tannins.

In addition, most iced coffee is served with a straw. Drinking through a straw will minimize direct contact between the coffee and your teeth, which will help reduce the acidic effects of the drink on your teeth. As a result, teeth can remain white maintained. 

Cold coffee is better than hot coffee, but...

Iced coffee is a favorite choice for many people to quench thirst, because it is not only fresher but also comes with a variety of additional flavors and variations in how to serve it. 

However, don't be fooled by the colorful syrup and the sweetness of the whipped cream that adorns your iced coffee. These kinds of creative toppings will double the nutritional and calorie value of black coffee, which was previously zero. 

Not to mention, generally iced coffee is served in a larger container than a cup of hot coffee. The benefits of coffee will not be felt by the body if you consume it in this way because the health risks of added calories and sugar will outweigh the actual benefits of coffee. 

To be able to achieve all the benefits of drinking coffee as optimally as possible, you should choose black coffee without sugar and other sweeteners. Whether it's in an iced version or accompanied by a warm steam moon. 

You also still have to pay attention to your daily coffee portion every day. The reason is, drinking coffee can actually be a master's weapon for your health.
