Your A1C reflects your average blood sugar levels over the past two to three months, making it an important measure of long-term blood sugar management. Research shows that following a Mediterranean eating pattern can help improve A1C levels while supporting heart health and overall well-being.
Rather than being a strict diet, the Mediterranean eating pattern is a flexible way of eating that emphasizes vegetables, fruits, whole grains, beans, lentils, nuts, seeds, fish, and healthy fats such as olive oil, while limiting highly processed foods, sugary foods and drinks, as well as processed meats.
These foods are rich in fibre, healthy fats, vitamins, minerals, and antioxidants that help reduce blood sugar spikes after meals, support heart health, and may improve insulin sensitivity over time.
Did You Know?
The Mediterranean eating pattern can fit any cuisine.
You don’t have to eat Mediterranean foods to enjoy its benefits. Whether you prefer Asian, South Asian, Middle Eastern, African, Latin American, Caribbean, or European cuisine, you can apply the same principles by choosing more vegetables, legumes, whole grains, lean proteins, and healthy fats. It’s about how you build your meals, not the recipes you follow.
Tips for Following a Mediterranean Eating Pattern
1. Fill Half Your Plate with Vegetables
Vegetables are rich in fibre, vitamins, minerals, and antioxidants. Aim to fill half your plate with a variety of colourful, non-starchy vegetables to support steady blood sugar levels and overall health.
2. Choose Whole Grains More Often
Choose whole grains such as oats, barley, quinoa, brown rice, and whole grain bread or pasta instead of refined grains whenever possible. They contain more fibre and can help support steadier blood sugar levels.
Because grains are a source of carbohydrate, portion size is just as important as choosing high-fibre options.
3. Include More Plant Proteins
Beans, lentils, chickpeas, tofu, tempeh, and edamame provide both protein and fibre, making them excellent choices for blood sugar management. Try including them more often in place of red or processed meats.
4. Choose Lean Protein Foods
Include lean protein foods such as fish, skinless poultry, eggs, tofu, and lower-fat dairy products to help build balanced, satisfying meals.
5. Eat Fish at Least Twice a Week
Aim to eat fish at least twice a week. Fatty fish, such as salmon, trout, sardines, and mackerel, provide heart-healthy omega-3 fats, while white fish such as cod, haddock, and tilapia are excellent lean protein choices.
6. Choose Healthy Fats
Replace butter or shortening with healthy fats such as olive oil, avocado, nuts, and seeds whenever possible. While these foods support heart health, they are also high in calories, so enjoy them in moderate portions.
7. Limit Red and Processed Meats
Choose red meat less often and limit processed meats such as bacon, sausages, deli meats, and hot dogs. Instead, include more fish, legumes, or other lean protein foods throughout the week.
8. Enjoy Fruit as a Snack or Dessert
Fresh, frozen, and unsweetened canned fruit can all be part of a healthy eating pattern. For a more satisfying snack, pair fruit with a source of protein or healthy fat, such as plain Greek yogurt, cottage cheese, or a small handful of unsalted nuts.
9. Build Balanced Meals
A simple way to put the Mediterranean eating pattern into practice is to use the Diabetes Canada Plate Method:
- ½ plate: Non-starchy vegetables
- ÂĽ plate: Lean protein
- ÂĽ plate: High-fibre carbohydrates, such as whole grains, beans, lentils, or starchy vegetables
Add a small amount of healthy fat, such as olive oil, avocado, nuts, or seeds.
Remember that portion sizes matter, especially for carbohydrate foods. A registered dietitian can help you determine the portions that best meet your individual needs.

The Mediterranean eating pattern is a flexible, enjoyable, and evidence-based approach to eating that can help improve A1C levels while supporting heart health.
Best of all, it can be adapted to your favourite cultural foods, family traditions, budget, and lifestyle. You don’t need to completely change the foods you eat. Small, consistent changes like eating more vegetables, choosing whole grains more often, including beans and lentils, and replacing saturated fats with healthier fats can make a meaningful difference over time.
