Drinking a lot of coffee can cause side effects such as increased heart rate, anxiety, indigestion, and insomnia. It’s because of caffeine. According to the U.S. Food and Drug Administration (FDA), it is generally safe to consume up to 400 mg of caffeine per day.
However, experts recommend that people who have low caffeine tolerance or are pregnant or breastfeeding should limit their caffeine intake.
Many of these people choose decaffeinated coffee as an alternative.
How do you make decaffeinated coffee?
There are three main ways to remove caffeine from coffee. ▲Method using water (Swiss Water Process) ▲Method using solvent (methylene chloride, ethyl acetate) ▲Method using carbon dioxide.
Among them, the extraction method using methylene chloride as a solvent is called the European method, and controversy over its harmfulness has recently emerged. In experiments on rats, it was discovered that consuming large amounts of methylene chloride could cause cancer.
Accordingly, the U.S. non-profit organization ‘Environmental Defense Fund’ submitted a petition to the Food and Drug Administration (FDA) in January to ban the use of this substance in food production.
“Intake is important,” registered dietitian Miranda Kalati said in a recent interview with USA Today.
Most of the compounds used in the decaffeination manufacturing process, such as methylene chloride, are removed during the processing process. The FDA set the residue standard at less than 0.001%. This is said to be a small enough amount that it does not actually affect health.
Nevertheless, Mr. Galati advised, “It is better to choose decaffeinated coffee made using the Swiss water process or another method that does not use methylene chloride.”
In Korea, coffee ingredients must be extracted using only water, alcohol, and carbon dioxide. However, this is not something to be reassured about. European style is considered to be relatively less expensive and has better flavor, so a significant amount of decaffeinated coffee distributed globally uses methylene chloride as a solvent. There is a possibility that it is mixed among imported products. If you are unsure, you should carefully examine the brand before making your choice.
Is decaffeinated coffee better for your health?
Most nutrition experts say the term ‘healthiest’ is subjective. Because health goals and concerns are different, the standards set for each person are also different.
According to Johns Hopkins University School of Medicine, both caffeinated and decaffeinated coffee offer similar health benefits, including healthy liver enzyme levels and a reduced risk of colon cancer.
Mr Galiti said caffeinated coffee “may offer unique benefits, such as improved mood, improved alertness and improved athletic performance.” However, he explains, “If caffeine makes you feel jittery, anxious, or interferes with your sleep, it’s best to drink decaffeinated coffee. Decaffeinated coffee offers many of the same benefits as regular coffee without the potential downsides of caffeinated coffee.” .
He added, “Decaffeinated coffee contains antioxidants and other plant compounds that may help prevent type 2 diabetes, mental decline, and some cancers.”
