While it may be tempting to drink coffee the moment you get out of bed, a study from the University of Bath suggests that may not be the best idea.
Apparently, when you drink a strong coffee first thing in the morning, you impair the body’s glucose response. This limits your body’s ability to effectively tolerate sugar in breakfast and can affect overall metabolic and blood sugar control, especially if you slept badly the night before. In the study, those who drank coffee after having breakfast didn’t suffer from such blood sugar problems, suggesting it’s wiser for you to avoid drinking coffee before you eat.
“Put simply, our blood sugar control is impaired when the first thing our bodies come into contact with is coffee especially after a night of disrupted sleep,” said James Betts, the corresponding author of the new study. “We might improve this by eating first and then drinking coffee later if we feel we still need it. Knowing this can have important health benefits for us all.”
