If u can tolerate something like 30-35g carb per meal or 100g carbs a day without your bg going overboard, you can add fruits to your diet quite easily. Take whole fruits about 100g serving per meal, avoid juice and blending fruits (made the glycaemic index much higher). When you take fruit in a meal, you will need to reduce your grains, vegetable roots, and other carbs to ensure your total carb intake for that meal do not make your two hours bg go overboard.
Some fruits are better than others. The good ones from my observation are payaya, orange. Be cautious about those vert sweet and low fibre varieties. At times, i also regularly use red tomato as fruit intake because they are technically a fruit but much lower in carb and high in lycopene. I also like use 5 black grapes with some payaya to make up 100g, to be taken before exercising.
