You're not alone if you start your day with coffee. Coffee can enhance alertness, attention, and make it easier to get out of bed, but it can also affect blood sugar.
Particularly if you are prediabetic or diabetic, the caffeine in coffee can have a dramatic impact on your blood sugar levels.
If you are watching your blood sugar levels, drinking coffee before breakfast is the worst habit you can have.
In a study conducted in 2020, British researchers discovered that consuming two cups of coffee before breakfast elevated blood sugar levels by up to 50 percent.
Caffeine suppresses adenosine. Adenosine helps your body manufacture and respond to insulin. This reduce insulin release & cell sensitivity, resulting to increased blood glucose.
Caffeine's potential to raise stress hormones like cortisol and epinephrine is a second way in which it might cause blood sugar levels to rise.
These hormones raise blood sugar in order to provide you with readily available energy to resist stress. As insulin synthesis decreases, blood sugar levels rise.
Waiting to drink your coffee until after you've had a nutritious breakfast will help reduce the impact it has on your blood sugar.
If you need something to get you going in the morning, try a cup of tea, half-caf coffee, or simply limit your coffee to 6 ounces.
