Sugar in coffee or tea may not greatly affect health

A recent study has set out to answer one of life’s burning questions: does adding sugar to our daily cup of coffee or tea pose any health risks? Researchers from Denmark and the Netherlands embarked on this sugary mission, examining data from the longitudinal Copenhagen Male Study. Their findings may not be as sweet as that extra spoonful of sugar, but definitely worth a stir.

Pouring Over the Results

The study delved into the incidence of diabetes, deaths caused by heart disease or cancer, and all-cause mortality. So, did adding sugar to coffee or tea significantly impact these health outcomes? Drum roll, please… Not really. The researchers found that the addition of sugar didn’t pose any significant health risks.

Now, before you start celebrating this news with a spoonful of sugar, remember that excess sugar intake can still lead to health issues like tooth decay, obesity, and heart disease. The American Heart Association recommends limiting added sugar to 9 teaspoons for men and 6 teaspoons for women per day. Unfortunately, many people tend to exceed these recommendations, especially when a single can of soda contains more sugar than both men and women should consume in an entire day.

Whittling Down the Participants

To conduct their study, the researchers analyzed data from the Copenhagen Male Study, which started in the 1970s and focused on Danish men aged 40-59. The researchers looked at the coffee and tea habits of 2,923 men who had no history of heart disease, cancer, or type 2 diabetes. They meticulously combed through medical records, questionnaires, and follow-up appointments to assess the impact of sugar.

A Tea-sy Bit of Sugar

While the researchers didn’t ask participants about exact quantities of sugar added to their beverages, they assumed it was a small amount. And here’s when the sugar cubes start to crumble: the study revealed no statistically significant association between using sugar in coffee or tea and all-cause mortality, heart disease mortality, cancer mortality, or incident diabetes mellitus.

Sure, the sugar group had slightly higher death rates (89.9%) compared to the “no sugar” group (87.5%). But the differences were not significant enough to cause concern. Similarly, when it came to heart disease mortality, the sugar group had a slightly higher rate (38.2%) than the “no sugar” group (35.3%). The incidence of type 2 diabetes was also comparable between the two groups.

At-Home Drinks vs. Prepared Drinks

Before you start dunking your cookies into a sugar-laden coffee shop creation, keep in mind that this study focused on sugar added to homemade tea or coffee. These beverages usually contain significantly less sugar than their prepackaged counterparts. While most people add one or two teaspoons of sugar (about 4 grams per teaspoon) to their drinks at home, flavored coffee drinks from your favorite chain store can contain upwards of 30 grams of sugar.

Dr. Sarah Stombaugh, a family medicine physician who wasn’t involved in the study, underscores the importance of this distinction. She says that adding small amounts of sugar at home can be done without serious risk. However, those indulgent coffee shop treats should be approached with caution, as they often pack a sugary punch that rivals the destructive power of a kung fu kick.

Making Healthy Choices

While this study may offer reassuring news for sweet-toothed coffee and tea lovers, it’s vital to maintain a balanced and mindful approach to nutrition. The Centers for Disease Control and Prevention (CDC) recommend that added sugars should make up less than 10% of our daily caloric intake. But be warned, sugar can sneak its way into various consumables.

If you’re looking for sweetness, why not turn to fruits? Sure, they contain sugar, but they also provide essential nutrients and fiber that aren’t found in sugary beverages or snacks. As for that daily cup of joe or tea, a touch of sugar won’t hurt. Just remember to keep it within moderation, sit back, and enjoy your drink guilt-free.
