This was down voted, but it's all about the time scale. A major pathway of transporting energy from your food to your cells is via glucose in your blood and your cells then use or store it for later. Insulin production reduces the spike, but that response isn't instantaneous. So on a second by second basis numbers that would be concerning across an hour are fine. Similarly your average over an hour post meal can be much higher than a healthy average across a day.
