High glucose spikes common in healthy people
Normal blood glucose levels are often not normal at all — they stray much farther from the healthy ranges than commonly thought, according to research that reveals new patterns of glucose dysregulation in otherwise healthy people.
The research found that those considered non-diabetic by standard measures, in fact, often experience frequent elevations in blood glucose levels into the impaired glucose-tolerant or diabetic range.
Looking at the glucose spikes from 57 participants, the study authors found that most people can be classified into three distinct glucotypes or glucose behaviours: those whose glucose does not vary much (low); those who spike often (severe); and those in between (moderate).
To assess how different people react to the same meal, the team provided three different standardised breakfasts — cornflakes with milk, bread with peanut butter, and a nutrition bar.
