My blood sugar dipped in the evening, and I started experiencing mild hypoglycemia symptoms (a feeling of unease and shaky hands). Thanks to a timely boost with ramune candies, I was able to prevent a sharp drop. With the hot season approaching, there's always the worry of emergency snacks melting in my bag, but ramune is a reliable, melt-proof option I can carry anywhere. The blood sugar rise was gentler than expected, and the subsequent stabilization was perfectly ideal, making for a reassuring day.

Highlights

After 4:30 PM, my blood sugar dropped to 74 mg/dL, and I started feeling signs of hypoglycemia.
Eating 3 large-grain Morinaga Ramune candies gently raised my blood sugar by approximately 37 mg/dL.
The peak after the snack was kept around 111 mg/dL just after 5 PM, and the subsequent decline was very smooth.

[My Ramune Glucose Data]

Around 4:30 PM, you can clearly see the graph line dip to 74 mg/dL, just touching the green dotted line.
After eating 3 ramune candies around 4:50 PM, the graph gracefully curved upwards, forming a gentle peak.
Without any sharp spikes, by 5:30 PM, my blood sugar smoothly returned to a stable range in the 80 mg/dLs.

Japanese Food Mastering Blood Sugar with Type 1 Diabetes: A Personal Journey

　Here's how my blood sugar reacted after I had a Châteraisé soda ice pop for an afternoon snack. The impact of this frozen treat, which contains no fat or protein, is clearly visible in the graph.

　I know I seem to eat a lot of Châteraisé ice cream, but that's just because there's one nearby and they have so many tasty *and* affordable options. Rest assured, I am definitely NOT a shill for Châteraisé! (lol)

Key Takeaways

My blood sugar started rising immediately after eating the ice pop.
Since it contained absolutely no fat or protein, the carbohydrates seemed to be absorbed directly and quickly.
Although it seemed to stabilize for a moment, the subsequent rise in blood sugar is likely due to my lunchtime insulin wearing off and the effects of coffee.

My Blood Sugar After a Soda Ice Pop

The characteristics of this frozen treat—0.0g of fat and protein, and 13.4g of carbohydrates per stick—directly led to a significant spike in blood sugar.
The sugars and high-fructose corn syrup in the ingredients have a high GI (glycemic index, or speed of carbohydrate absorption), which I believe caused the rapid blood sugar increase seen in the yellow-hatched section starting from 14:20.
From a low of 97 mg/dL at 14:20, my blood sugar rose to approximately 130 mg/dL within just 50 minutes, during the hatched period.
Overall, there was a substantial blood sugar spike of +54 mg/dL. The subsequent rise is likely due to having almond sardines with coffee, and my lunchtime insulin effect wearing off. (My best guess!)
Despite being a modest 51 kcal, my blood sugar still climbed this high, simply because there was no "cushioning effect" from fat.

Weekly Blood Glucose Report (Week of May 24, 2026)

This week, my baseline blood sugar shot up dramatically from the middle to the latter half of the week. On Thursday, I even recorded a temporary, furious spike exceeding 400 mg/dL [cite: 1]. While I managed to recover towards the weekend, finally dropping to a reassuring level by Sunday night, it was a generally nerve-wracking week with intense fluctuations [cite: 1].

Weekly Continuous Trends

Day-by-Day Summary Analysis

On Thursday, May 21st, the graph turned stark red and shot up towards the evening, reaching a weekly high of 411 mg/dL. This was a major setback [cite: 1].
On Tuesday, May 19th, I observed a jagged and intense waveform with frequent ups and downs throughout the day, marking it as the most unstable period of the week [cite: 1].

Time-of-Day AGP Analysis

During the sleeping hours, from late night to early morning, my levels remained relatively calm, staying within the green baseline (below 180 mg/dL) [cite: 1].

Daily Summary

By Sunday night, my baseline finally dropped, firmly settling at the week's lowest point of 84 mg/dL, ending the week on a reassuring note.

Time-of-Day AGP Profile

Around 9 AM, the median of the dark blue line sharply surged, confirming this is the time when the impact of breakfast is most evident.
Around 6 PM, another clear peak was observed, suggesting I need to pay close attention to the carbohydrate content and eating order of dinner.
