Preparing for surgery involves more than just the logistics of the procedure itself. Nutrition plays a vital role in ensuring optimal outcomes and a smoother recovery. An anti-inflammatory diet, in particular, can offer significant advantages in the weeks and months leading up to surgery.
Understanding Inflammation and Its Impact
Inflammation is a natural immune response to injury or irritation. However, chronic, low-grade inflammation can hinder healing processes. Certain foods, especially those that are processed and high in sugar, can promote inflammation within the body. Medical conditions such as Crohn’s disease, ulcerative colitis, irritable bowel syndrome, heart disease, elevated blood pressure, diabetes, and obesity can induce inflammation. Recognizing the signs of inflammation is also important; these can manifest as swollen fingers, tight rings, abdominal distention, or fluid retention.
How an Anti-Inflammatory Diet Helps
Adopting an anti-inflammatory diet helps reduce this chronic inflammation, allowing the immune system to respond more effectively to the surgical procedure. This dietary approach offers numerous benefits:
- Building Nutrient Reserves: A nutrient-dense diet helps build up the body’s reserves of essential vitamins, minerals, and beneficial compounds, providing the necessary building blocks for healing and stress management during surgery.
- Targeted Immune Response: By avoiding pro-inflammatory foods, the immune system can mount a more targeted response to the surgical site, promoting efficient healing.
- Stable Blood Sugar: Avoiding sugary foods and refined carbohydrates prevents blood sugar spikes and dips, supporting a well-regulated metabolism and consistent energy levels.
- Weight Management: If weight loss is desired before surgery, an anti-inflammatory diet can aid in shedding extra pounds while providing essential nourishment.
- Healthy Gut Microbiome: A fiber-rich diet supports beneficial gut bacteria, strengthening immune function, reducing inflammation, and influencing mood and energy levels.
- Healthy Skin: Nutrients from whole plant foods and omega-3 fats nourish and strengthen the skin, while limiting sugar prevents damage to collagen and elastin.
Basics of an Anti-Inflammatory Diet
An anti-inflammatory diet focuses on minimally processed, whole foods. Processed foods, often found in boxes, bags, or cans, contain multiple ingredients, including unrecognizable or non-food substances. A whole food, on the other hand, is a one-ingredient item like an apple, orange, or cucumber.
Key Components:
- Minimally Processed Foods: Focus on whole, one-ingredient foods.
- Healthy Fats: Include sources like avocados, olive oil, fatty fish (salmon), nuts, and seeds, which provide anti-inflammatory omega-3 fats.
- Lean Proteins: Opt for fish, poultry, eggs, beans, lentils, tofu, and plain Greek yogurt.
- Complex Carbohydrates: Choose whole foods like fruits, vegetables, and whole grains, which provide fiber, vitamins, and minerals.
- Herbs and Spices: Incorporate ginger, turmeric, garlic, cinnamon, and rosemary for their potent anti-inflammatory effects.
- Hydration: Aim for 2-3 liters of fluid daily, mainly from water, herbal teas, and low-sodium broths.
Specific Diets to Consider
While the term "anti-inflammatory diet" doesn't refer to a specific regimen, several diets fall within this category:

- Mediterranean Diet: This diet emphasizes whole foods, including fish (especially omega-3 rich options like salmon and tuna), fresh fruits and vegetables, legumes, nuts, and extra virgin olive oil. It eliminates processed oils found in ultra-processed foods.
- DASH (Dietary Approaches to Stop Hypertension) Diet: Designed to reduce blood pressure, the DASH diet is similar to the Mediterranean diet but doesn't specifically emphasize fish or extra virgin olive oil to the same extent.
- Plant-Based Diet: A whole foods plant-based diet can help suppress inflammation, provided it focuses on minimally processed options. High-quality, grass-fed, organic lean meats can also be included in moderation.
Foods to Embrace and Avoid
Foods to Embrace:
- Fruits and Vegetables: Colorful fruits and vegetables are rich in antioxidants and fiber.
- Healthy Fats: Avocados, olive oil, fatty fish, nuts, and seeds.
- Lean Proteins: Fish, poultry, eggs, beans, lentils, and tofu.
- Whole Grains: Brown rice, quinoa, oats, and whole-grain bread.
- Spices: Turmeric, ginger, garlic, cinnamon, and rosemary.
Foods to Avoid:
- Processed Foods: Packaged snacks, fast food, and convenience meals.
- Sugary Foods: Candy, cookies, cakes, soda, and fruit juice.
- Refined Grains: White bread, pasta, and pastries.
- Fried Foods: Foods soaked in oil with Omega 6 fatty acids.
- Unhealthy Fats: Foods high in saturated and trans fats, such as fried foods, heavy meats, and cured meats.
- High-Sodium Foods: Many soups and snack foods.
Personalizing Your Anti-Inflammatory Diet
Identifying personal trigger foods is crucial. An elimination diet can help determine which foods cause an inflammatory reaction in your body. Start by cutting out ultra-processed foods, artificial sweeteners, gluten, and processed dairy and sugar. If symptoms persist, further eliminate highly allergenic foods. Skin and blood tests can provide additional guidance by identifying foods that trigger an increased antibody response.
Sample Meal Plan
Here’s a sample meal plan for a week on an anti-inflammatory diet. Remember to stay hydrated by sipping on water, herbal teas, and low-sodium broths throughout the day. Feel free to adjust portion sizes based on your individual needs and hunger levels. If you have specific dietary restrictions or allergies, make substitutions as needed. The key is to focus on whole, minimally processed foods while limiting sugary, refined, and fried fare.
When building your own meals and snacks, focus on combining a balance of fibre-rich whole grains or starchy vegetables, colourful non-starchy vegetables, plant or lean animal proteins, and healthy fats. Some dairy can be included in moderation, but it’s best to choose low-fat or non-dairy options. Yogurt and kefir with live cultures can be beneficial due to their probiotic content. However, some people may be sensitive to dairy, so pay attention to how your body responds. Focus on healthy, unsaturated fats from sources like nuts, seeds, avocados, olive oil, and fatty fish. These contain beneficial compounds like omega-3s and monounsaturated fats.

Practical Tips for Transitioning
Transitioning to a new way of eating can be challenging. Start by making small, gradual changes. Begin with the foods you know don't serve you well, such as highly processed items. Instead of eliminating everything at once, focus on reducing sugar or salt intake first. Give yourself six months to a year to fully change your diet, as drastic changes rarely lead to long-term success.
Eating Out on an Anti-Inflammatory Diet
It is possible to maintain an anti-inflammatory diet even when eating out. Many restaurants now offer whole grain, vegetarian, and vegan options. Look for dishes featuring vegetables, whole grains, legumes, and lean proteins. Don’t hesitate to ask for modifications like dressing on the side or no added salt.

Benefits Beyond Surgery
Following an anti-inflammatory diet offers benefits beyond surgical preparation. It can improve energy levels, digestion, sleep, and overall well-being. Many individuals notice reduced swelling, improved sleep, weight loss, and better blood pressure and blood sugar values. Mental benefits include reduced anxiety, stress, and brain fog.
The Role of Probiotics and Prebiotics
- Probiotics: Live microorganisms that confer health benefits when administered in adequate amounts. While research on their effectiveness in treating inflammatory bowel disease (IBD) is ongoing, some studies suggest that probiotics can help maintain remission in ulcerative colitis (UC) patients. Foods like yogurt and fermented milk supplemented with bifidobacteria may also be beneficial.
- Prebiotics: Non-digestible food ingredients that support the growth and activity of health-promoting bacteria in the gastrointestinal tract. Oat bran and germinated barley foodstuff (GBF) have shown promise in improving gastrointestinal symptoms and reducing inflammation in UC patients.
Consulting a Dietician
Dieticians can provide personalized guidance in creating an anti-inflammatory diet plan. They can review your current eating habits and suggest specific foods to eliminate or incorporate. Tracking your food intake and symptoms is essential, especially when following an elimination diet.
