White Bread with Jam and the Blood Sugar Rollercoaster

In my bachelor’s in human nutrition, we were split into groups for a simple experiment. We were going to test how different breakfasts affected fasting blood sugar. One group had egg and bacon, basically keto. Another tested a smoothie. A third ate whole grain bread with ham, cheese, and vegetables. And one group, my group, tested white bread with jam.

I had never eaten white bread with jam for breakfast. Not like that. Not as a deliberate “test meal” on an empty stomach, watched and measured. I still remember the moment I saw my blood sugar curve. It felt like watching a rocket launch. A sharp rise, then a drop. And in my body, it felt just as dramatic. I felt shaky, heavy, off. Not just hungry again, but wrong. Like my system had been pushed and then left to deal with the consequences.

Watching everyone’s results side by side did something to me. It made nutrition feel less like theory and more like physiology in real time. The same classroom. The same assignment. Different breakfasts. Different bodies. Different curves.
