Sri Lankan cuisine is unique blend of South Asian (especially Tamil and Sinhalese), Arab trader, Portuguese, Dutch, and British colonial influences. Healthy components – fish (Sri Lanka is island; abundant seafood); chicken; lentils (dhal); abundant vegetables; coconut (fresh and milk); aromatic spices (cinnamon – Sri Lanka is major producer; cardamom, cloves, pepper, turmeric, fenugreek, curry leaves); chili (bird’s eye); herbs; rambutan and mango. Distinctive features – very spicy food (one of world’s spiciest cuisines); rice as staple (multiple meals per day); coconut in many forms; curry leaves; pandan leaf; tempering technique. Concerns – white rice (bath) in large portions; hoppers (rice/coconut crepes); string hoppers (rice noodles); pittu (rice/coconut steamed mix); kiribath (milk rice with coconut); roti (often coconut milk added); curd and treacle (jaggery-based sweet); pol sambol can be high oil; ghee in some dishes; sweetened tea. Sri Lanka has 8-10% adult diabetes prevalence; rising in urban populations. South Asian populations – higher lifetime diabetes risk overall. Best choices – fish curry (ambul thiyal – sour fish curry with goraka; very flavorful, low oil); chicken curry (kukul mas); crab curry (small portion); dhal curry (parippu – lentils with coconut milk); mallum (chopped greens with coconut – very diabetes-friendly); vegetable curry; ela batu (tender brinjal); winged bean curry; pol sambol (coconut-chili-onion-lime relish – moderate portion); kola kanda (herbal porridge); soups. Watch portions – rice (bath) main carb culprit; hoppers (appa); string hoppers (idi appa); pittu; kiribath (festive milk rice); kottu (chopped roti with vegetables/meat; very high carb); rotti; curd and treacle; watalappan (jaggery custard); kavum (oil sweet); aluwa; sweet biscuits. Coconut is in virtually every Sri Lankan meal – fresh grated coconut, coconut milk (thick and thin extractions), coconut oil, coconut treacle, young coconut water, coconut flesh. Nutrition – coconut high in saturated fat (medium-chain triglycerides – MCT including lauric acid); cardiovascular implications historically debated. Per ½ cup coconut milk (canned full-fat) – 230 cal, 5 g carb, 1 g fiber, 2 g protein, 24 g fat (22 g saturated). For diabetes – coconut milk increases calorie and saturated fat substantially; portion control important; “lite” coconut milk available (half calories/fat). Sri Lankan red rice (rathu kakulu) – whole grain, brown rice variety; lower GI than white; better fiber; available at Sri Lankan grocery stores. Strategies for rice – portion control (½ cup cooked rice per meal); brown rice substitute; cauliflower rice for some dishes; fill plate with curry and vegetables first; eat dhal/lentils first.
