The tomato soup from the popular ProLon fasting-mimicking diet was found to cause a significant average glucose spike of 53 mg/dL.

Across a dataset of 51 million glucose data points, Skittles were the single worst food, causing an average glucose rise of 83 mg/dL.

In an experiment, taking a simple walk after drinking a can of Coke lowered the median glucose spike by 33%.

Carbohydrates consumed alone without fat, protein, and fiber, referred to as 'naked carbs,' are more likely to cause significant blood sugar spikes.

Foods marketed as healthy, such as unsweetened oat milk, can cause a monumental glucose spike, whereas other non-dairy milks have virtually no response.

An optimal fasting glucose level is in the lower-normal range of 70-85 mg/dL, as levels in the high 90s are a lagging indicator of poor metabolic health.

Eating protein and fat before carbohydrates in a meal has been shown to significantly lower the subsequent glucose response.

Fructose doesn't spike glucose on a monitor but directly contributes to insulin resistance and fatty liver disease by creating uric acid and oxidative stress.

Peach pie causes a lower average glucose spike than many popular breakfast cereals like Cinnamon Toast Crunch, which is worse than eating dessert for breakfast.
