Why Tuna Helps
Tuna is a powerhouse for anyone watching their glucose. Its packed with highquality protein, omega3 fatty acids, and virtually zero carbs. Protein slows digestion, which helps prevent the spikes that can send your blood sugar soaring after a meal. Omega3s, on the other hand, have been linked to improved insulin sensitivitymeaning your cells respond better to the insulin you already have.
Now, you might have heard whispers like why is tuna not good for diabetics? The short answer is: it usually isnt. The real concerns are mercury and sodium, not sugar. Choosing lightinwater canned tuna, rinsing it before use, and limiting the frequency (no more than 23 servings a week) keeps those worries in check while still letting you reap the nutritional benefits.
According to a study published in the journal on fish consumption and insulin response, regular intake of omega3rich fish like tuna can modestly improve glycemic control in adults with type2 diabetes.
