Yes, this raspberry vinaigrette can be a suitable choice for diabetics, especially with a small modification. Maple syrup, while a healthier sweetener, does contain natural sugars which can affect blood glucose levels. To make the dressing more diabetic-friendly, consider eliminating the maple syrup from the recipe. The natural sweetness from the raspberries should provide a subtle sweetness. As always, it's recommended that individuals with diabetes consult their healthcare provider or a dietitian when incorporating new foods into their diet.
