Chemotherapy changes the way the body eats, digests, and regulates blood sugar. For people already living with diabetes, this can turn everyday meals into a source of confusion, discomfort, and anxiety. This cookbook was created to bring steadiness back to the table. Chemo & Diabetes Cookbook is a practical, compassionate guide for managing blood sugar during cancer treatment using meals that are gentle, easy to digest, and realistic for low-energy days. Every recipe is designed with the physical realities of chemotherapy in mind, including nausea, taste changes, appetite loss, fatigue, and digestive sensitivity, while still respecting the needs of diabetes management. This is not a restrictive or perfection-based diet. It is a flexible framework that supports stability rather than pressure. Meals prioritize soft textures, low added sugar, balanced carbohydrates, and adequate protein to help reduce sharp glucose swings without overwhelming the body. Inside this cookbook, readers will find thoughtfully developed recipes including restorative breakfasts, stabilizing smoothies, healing soups, and simple comfort meals that can be eaten even on difficult treatment days. Clear instructions, minimal ingredients, and adaptable options make cooking possible when energy is limited. The book is written for adults undergoing chemotherapy who are also managing diabetes, as well as caregivers who need clear guidance without medical jargon. It is equally useful for those experiencing steroid-related blood sugar fluctuations during treatment. This cookbook does not promise outcomes or cures. What it offers is support, clarity, and confidence during an uncertain time. Each meal is an invitation to nourish the body gently, maintain steadier blood sugar, and reduce daily food-related stress. Food during treatment should not be another battle. This book exists to make eating feel safer, calmer, and more manageable, one meal at a time.
