Herring (100 G)

Choose plain fresh, canned, or smoked herring without sweet glazes, sugar, honey, sweet sauces, or breading; check labels for added sugars and starches.

Avoid pairing herring with high-carbohydrate sides such as white bread, crackers, potatoes, or sweet pickles; instead serve it with non-starchy vegetables like cucumber, leafy greens, radishes, or broccoli.

Keep the herring portion moderate and eat slowly, especially if the meal also includes carbohydrate-containing foods.

Add fiber-rich low-starch foods to the meal, such as lentils, chickpeas, or a salad with chia or flaxseed, while keeping portions suitable for your carbohydrate target.

Use vinegar, lemon juice, herbs, mustard without added sugar, or olive oil for flavor instead of sweet marinades and creamy sweetened sauces.

If the rise continues with plain herring, compare your response to different brands or preparations and discuss recurring unexpected readings with a healthcare professional.
