Parsnips Overview

Parsnips are a sweet root vegetable similar to carrots but often even sweeter when roasted. They are high in carbohydrates compared to most vegetables and are not suitable for keto or strict low-carb eating. For diabetic-friendly plans, portion control is important because parsnips can raise blood sugar similarly to other starchy roots.
