Do you think age is also a factor?
When blood sugar levels are already elevated, then it mist be age-related. Lol.
But yeah, I couldn’t get my diabetic mom to skip sugar on her coffee, it it may really be by preferrence mostly. I started not putting sugar into my coffee (even the instant coffee powder) over 10 years ago, influenced by my very fit friend. Lol. But you know what I sometimes do? I eat dark chocolate with my black coffee. I love the way the chocolate melts in my mouth. 🤤
