This suggests that elements other than caffeine may be responsible for these protective effects ( 21). Each daily cup may reduce the risk up to 7% ( 17, 18, 19, 20). Type 2 diabetes, liver function, and premature deathĭrinking coffee, both regular and decaf, has been linked with reduced risk of type 2 diabetes. They cannot prove that coffee caused the benefits, only that drinking coffee is associated with them. This is because most studies assess coffee intake without distinguishing between regular and decaf coffee, and some don’t even include decaf coffee.Īlso, most of these studies are observational. However, the specific health effects of decaf coffee can be hard to determine. It’s linked with numerous health benefits, which are mainly attributed to its antioxidant content and other active substances. These include mainly chlorogenic acid and other polyphenols.ĭecaf coffee also contains small amounts of several nutrients.ĭespite having been demonized in the past, the truth is, coffee is mostly good for you. Summary:ĭecaf coffee contains similar amounts of antioxidants as regular coffee. This may not seem like a lot of nutrients, but the amounts add up quickly if you drink 2–3 (or more) cups of coffee per day. One cup of brewed decaf coffee provides 2.4% of the recommended daily intake of magnesium, 4.8% of potassium, and 2.5% of niacin, or vitamin B3 ( 1). In addition to the antioxidants, decaf also contains minor amounts of some nutrients. This reduces oxidative damage and may help prevent diseases like heart disease, cancer, and type 2 diabetes ( 13, 14, 15, 16). The main antioxidants in regular and decaf coffee are hydrocinnamic acids and polyphenols ( 1, 12).Īntioxidants are very effective at neutralizing reactive compounds called free radicals. This difference is most likely caused by a small loss of antioxidants during the decaffeination process. It’s actually the single biggest source of antioxidants in the Western diet ( 5, 6, 7).ĭecaf usually contains similar amounts of antioxidants as regular coffee, although they may be up to 15% lower ( 8, 9, 10, 11). Summary:ĭecaf coffee beans are washed in solvents to remove 97% of the caffeine content prior to roasting.Īside from the caffeine, the nutritional value of decaf coffee should be almost identical to that of regular coffee.ĭecaf coffee is loaded with antioxidants and contains nutrientsĬoffee is not the devil it’s been made out to be. This can make decaf coffee more pleasing to those who are sensitive to the bitter taste and smell of regular coffee. However, the taste and smell may become a little milder, and the color may change, depending on the method used ( 1). The nutritional value of decaf coffee should be almost identical to regular coffee, apart from the caffeine content. The beans are decaffeinated before they’re roasted and ground. Most of them include water, organic solvents, or carbon dioxide ( 1).Ĭoffee beans are washed in the solvent until the caffeine has been extracted from it, then the solvent is removed.Ĭaffeine can also be removed using carbon dioxide or a charcoal filter - a method known as the Swiss Water Process. There are many ways to remove caffeine from coffee beans. It’s coffee from coffee beans that have had at least 97% of their caffeine removed.
