Snacking with diabetes requires a dual focus: keeping blood glucose stable while also protecting cardiovascular health. The good news is that the snacks best suited to blood sugar management — those high in protein, healthy fats, and fibre — are also the ones with the strongest evidence for cardiovascular protection.
What Makes a Snack Heart-Healthy and Diabetes-Friendly?
The ideal snack for someone with diabetes and cardiovascular risk should: have a low glycaemic index (to avoid blood sugar spikes); contain protein and/or healthy fat (to slow glucose absorption and promote satiety); be low in sodium (to support blood pressure management); and be free from trans fats and refined sugars (which drive inflammation and LDL elevation).
