Do you drink coffee every day? Many people can’t get through the day without a couple of cups of coffee. Some even drink 5 or more cups every single day. While most drink coffee for the caffeine, there could be health benefits to the habit too. So is coffee healthy for you?
Is Coffee Healthy for You?
A new study analyzed the coffee consumption habits and subsequent mortality of over 200,000 participants over a span of 21 to 28 years. The researchers found that coffee consumption of up to 5 cups a day was associated with a significant reduction in mortality. Specifically, a cup a day or less was associated with a 5% reduction in mortality; 1.1 to 3 cups a day was associated with a 9% reduction in mortality; 3.1 to 5 cups a day was associated with a 7% reduction in mortality; More than 5 cups a day was associated with a 2% increase in mortality. The benefits of coffee were greater when controlling for smoking.
The researchers found reductions in cardiovascular disease, neurological diseases, and suicide. However, previous studies have also found benefits for type 2 diabetes, liver cancer, prostate cancer, skin cancer. Here are the cardiovascular disease and heart disease benefits found in another study.
The downside to coffee is the loss of sleep and anxiety associated with too much caffeine. However, the researchers found health benefits from both regular and decaf coffee. So, opt for decaf coffee if you suffer from these problems.
Coffee is healthy for you. The researchers suggested that the benefits could be due to “the chlorogenic acid, lignans, quinides, trigonelline, and magnesium in coffee [that] reduce insulin resistance and systematic inflammation.” So don’t be afraid to drink a couple of cups of coffee a day!
