Blood sugar control is central to metabolic health, energy levels through the day, and long-term risk of type 2 diabetes. The foods and eating patterns that support steady blood sugar are well studied — high-fibre, minimally processed foods that digest slowly tend to produce a gentler glucose response than refined, fast-digesting carbohydrates. This hub gathers the foods, compounds and lab markers from across the encyclopedia most relevant to blood sugar management.

Common questions
What’s the difference between fasting blood glucose and HbA1c? Fasting blood glucose is a snapshot of your blood sugar at one moment, while HbA1c reflects your average blood sugar over roughly the past two to three months, which is why HbA1c is generally considered the more reliable long-term marker for diabetes risk and management.
Does fibre really help control blood sugar? Yes, particularly soluble fibre — it slows how quickly carbohydrate is digested and absorbed, which blunts the blood sugar spike that follows a meal. This is one of the more consistently replicated findings in nutrition research.
