For coffee lovers, seasonal changes often change their habit of drinking coffee every morning, and the iced coffee in their hands gradually heats up to hot coffee as the temperature rises. Of course, both can provide you with much-needed caffeine, but a new study suggests that hot coffee may have more health benefits than cold coffee.

In a study published Oct. 30, 2018 in the journal Science report, researchers at Thomas Jefferson University in Philadelphia compared the acidity and antioxidant activity of hot and cold coffee. Hot coffee showed a higher level of antioxidant activity. Antioxidants are thought to be associated with some of the famous health benefits of drinking coffee, including reducing the risk of heart disease, diabetes and early death.

Dr. Megan Fuller, an assistant professor of chemistry at Jefferson and co-author of the study, said in a statement, "in the regulatory role, it shows that drinking coffee is good for the human body, especially hot coffee has stronger antioxidant capacity. "

However, Dr. Fuller and another co-author, Dr. Niny Rao, pointed out in the research paper, "further research is needed in the future to study any possible differences in the cooking temperature and time of coffee that have an effect on people's health. "

Dr Fuller and Dr Rao also found that hot coffee was similar to cold-extracted coffee in terms of acidity. Historically, cold-extracted coffee has been thought to be less acidic than hot coffee, so it is relatively mild for people's stomachs.

In the new study, however, the pH value (pH levels) of both cold and hot coffee samples fell between 4.85 and 5.13. According to this range of numbers, Dr. Rao said in a public statement that "a cup of cold coffee" should not be seen as a simple solution when the body needs caffeine but wants to avoid gastrointestinal suffering.

However, as a loyal fan of cold coffee, you don't have to worry so much. Because your favorite cold coffee still contains the antioxidants that people need. Antioxidants, like those found in other hot foods, such as polyphenols (polyphenols, also known as polyhydroxyphenols) and minerals (minerals), are health promoters.

Moreover, cold-extracted coffee still has its unique characteristics: cold-extracted coffee is usually more delicious. Dr. Frank Hu, dean of the Harvard School of Public Health and professor of epidemiology and nutrition, told Health that cold coffee has a special flavor, so people don't have to add any fat or calories, such as cream, milk or sugar, so as not to spoil its original charm. But sometimes, drinking hot coffee, which is more antioxidant, is also a good choice for coffee lovers.
