Mushrooms (1 Cup, Whole)

Check the mushroom dish for higher-carb additions such as flour-based sauces, breadcrumbs, sweet glazes, or large amounts of onions; these are often more likely to cause the rise than plain mushrooms.

Choose simply prepared mushrooms—grilled, sautéed, roasted, or in a clear broth—and avoid sugary sauces or breaded preparations.

Have mushrooms as part of a balanced meal with protein and fat, such as eggs, plain Greek yogurt, tofu, chicken, fish, or avocado, rather than eating the dish with refined starches.

Reduce the portion and test a smaller serving on a different day to see whether the response is dose-related.

Add low-starch vegetables such as spinach, broccoli, zucchini, bell peppers, or leafy salad to increase meal volume without adding many digestible carbohydrates.

Take a gentle 10–20 minute walk after eating, if appropriate for you, and compare your glucose response with and without the walk.
