The most common debate among coffee-holics are commonly around instant coffee and brewed coffee. Let’s talk about instant coffee:
Pro 1. It’s normally cheaper than ground or bean coffee, and it’s quicker and easier to prepare
Manufacturers use hot water to make a coffee extract from ground roasted coffee beans. Spraying the extract into hot air in a tall tank causes it to dry rapidly.
The other common method (Spray drying or air drying) involves freeze-drying coffee extract to make instant coffee power. In the freeze-drying process, cutting the coffee crystals results in granules. Instant coffee has a very long shelf life when compared to roasted or ground coffee, and comes in caffeinated and decaffeinated versions.
Pro 2. Instant Coffee Has Less Detrimental Effects on Cholesterol
Lesser cafestol in coffee is a substance that can elevate cholesterol. Both instant coffee and filtered coffee prepared in an automatic coffeemaker contain very small amounts of cafestol. If you already have high cholesterol or a family history of heart disease, instant coffee is a better choice than French-press or Turkish coffee.
Pro 3. Instant Coffee Improves Your Heart Health
Some scientific evidence exists to show that people who drink instant coffee have a lesser chance of developing heart disease than those that do not. A 2008 study published in the “Annals of Internal Medicine” followed 129,000 people over 20 years and determined that those who drank four or more cups a day were significantly less likely to die from heart disease.
Pro 4. Instant Coffee May Well Have Decreased Negative Effects On Heart Disease Compared To Brewed or Filtered
Instant coffee may have a different effect on heart health than non-instant coffee. According to a 1993 study published in the “Journal of Epidemiology,” which surveyed 10,000 men and women and compared the rates of heart disease to those who drank five or more cups of instant coffee per day. Those who drank five or more cups of coffee had lower heart disease rates than those who did not. This study contradicted earlier studies that found an elevated risk of heart disease for coffee drinkers, but those studies centered on people who drank filtered or boiled coffee.
Con 1. Hallucinations with Instant Coffee
A preliminary study by a Durham University team in 2009 showed that people who drink seven cups or more of instant coffee a day are at a high risk of suffering hallucinations. This could be because caffeine increases the production of cortisone, a stress hormone.
Con 2. Toxic Compounds Are Much Much Higher In Instant Coffee
Instant coffee is high in acrylamide, a chemical compound that has been shown to cause cancer in animals. According to the Food and Drug Administration, acrylamide can also cause nerve damage. Acrylamide happens naturally in certain foods during high-temperature heating. Because the presence of acrylamide in food wasn’t discovered until 2002, scientists still don’t know the full extent of its dangers. The amount of acrylamide is measured in ppb, or parts-per-billion. Certain brands and types of instant coffee have very high amounts, compared with ground coffee. Nescafe Classic Instant Coffee has 471 ppb according to the FDA. In comparison, Classic Roast brewed coffee has only 13 ppb.
Con 3. Lower Antioxidant Properties
Coffee is rich in antioxidant compounds, which help protect the body against the harmful effects of free radicals. Free radical damage has been implicated in a variety of chronic diseases and conditions, including cancer, cardiovascular disease and aging. According to W.W. Huber and W. Parzefall at the Medical University of Vienna, coffee contains the compound methylpyridinium, which has anti-cancer properties and isn’t found in any other food source. Methylpyridinium isn’t found in the raw coffee beans but is formed during the roasting process from trigonelline. Which instant coffee has lesser.
Con 4. Caffeine Content lower in Instant Coffee
Instant coffee is lower in caffeine than brewed coffee. Instant coffee contains an average of 93 mg of caffeine in a prepared 8 oz. serving, according to the Center for Science in the Public Interest. The range of caffeine content in a 8 oz. cup of instant coffee is 27 to 173 mg. An 8 oz serving of regular brewed coffee contains an average of 133 mg of caffeine, with a range of 102 to 200 mg of caffeine. The type of coffee beans and brewing methods however did affect the caffeine content in coffee.
Personally I loves brewed coffee because I like coffee made by barista, a dedicated cup of coffee just for me. 🙂
