Why food choices matter so much with diabetes
Diabetes is a condition where blood glucose (blood sugar) runs higher than it should, either because the body does not make enough insulin or does not use it well. Food has a direct, daily effect on blood glucose, which is why nutrition is such an important part of living with diabetes, alongside any medication, activity and monitoring your doctor advises. The reassuring part is that a diabetes-friendly diet is not a strange or expensive one. It is largely the balanced, mostly home-cooked Indian eating that suits the whole family.
What is the glycaemic index, and why does it matter?
The glycaemic index (GI) is a way of ranking carbohydrate foods by how quickly they raise blood glucose. High-GI foods, such as refined flour, white bread and sugary drinks, tend to spike blood sugar; lower-GI foods, such as whole pulses, millets and most vegetables, raise it more gently. GI is a useful idea rather than a strict rule. How a food is cooked, how much you eat and what you eat it with all change the effect. Pairing carbohydrates with protein, fibre and healthy fat generally slows the rise.
Which Indian foods are diabetes-friendly?
- Whole grains and millets such as bajra, jowar, ragi, brown rice, whole wheat, dalia and oats
- Pulses and legumes such as dal, chana, rajma, moong, lobia and sprouts
- Non-starchy vegetables such as leafy greens, bhindi, lauki, tinda, capsicum, cabbage and gourds
- Protein such as curd, paneer, eggs, fish, lean chicken and soya
- Whole fruit in sensible portions such as guava, jamun, apple, pear, orange and papaya
- Healthy fats such as nuts, seeds, and a little mustard or groundnut oil, plus methi seeds, cinnamon and plenty of water
Which foods should you limit?
- Sugary drinks, packaged juices and sweets
- Refined flour (maida) foods such as white bread, naan, biscuits and most bakery items
- Deep-fried snacks and namkeen
- Large portions of white rice and refined cereals
- Sweetened tea and coffee, and sugar-laden desserts
- Highly processed packaged foods high in sugar, salt or refined starch
How should you build a diabetes-friendly plate?
A simple, widely used idea is to picture your plate in parts: fill about half with non-starchy vegetables and salad, about a quarter with protein such as dal, curd, paneer, egg, fish or chicken, and about a quarter with a whole-grain carbohydrate such as millet roti or brown rice. Eating vegetables and protein alongside the carbohydrate, rather than a large plate of rice alone, helps flatten the rise in blood glucose. Regular meal timings and not skipping meals also help many people keep sugars steadier.
Building the plate, and the day around it
The same shape works at lunch and at dinner, and it is easier to hold to than a list of banned foods.
Fill half the plate with vegetables
Leafy greens, bhindi, lauki, tinda, capsicum, cabbage and gourds take up the most room and cost the least in blood glucose.
Give a quarter to protein
Dal, curd, paneer, egg, fish or chicken. This is the part most Indian plates are short of, and it steadies everything else on them.
Leave a quarter for the grain
Millet roti or brown rice rather than a large plate of white rice on its own. The portion matters more than the choice of grain.
Eat them together, not in turn
Vegetables and protein alongside the carbohydrate flatten the rise far more than the same food taken as a plate of rice first.
Keep the timings steady
Regular meals, and no skipped ones, help many people hold their sugars steadier through the day.
Keep dinner light and early
Moong and vegetable khichdi, or grilled paneer or fish with sauteed vegetables, is enough at the end of the day.
What does a sample diabetes-friendly Indian day look like?
This is a general illustration, not a prescription. Your portions and timings should be set with your doctor or dietitian, especially if you take medication.
- Early morning: warm water with a few soaked methi seeds or almonds
- Breakfast: vegetable besan chilla, moong dal chilla or vegetable oats with curd
- Mid-morning: a whole fruit such as guava or an apple
- Lunch: two millet or wheat rotis, dal or rajma, a large vegetable sabzi, salad and curd
- Evening: roasted chana or sprouts with unsweetened tea
- Dinner: light and earlier; vegetable and moong khichdi, or grilled paneer or fish with sauteed vegetables
Do people with diabetes have to give up rice, roti and fruit?
Usually not. Rice, roti and whole fruit can all fit into a diabetes-friendly diet when the portions are sensible and they are combined with protein, fibre and vegetables. Whole fruit, eaten whole rather than juiced, brings fibre and nutrients; it is fruit juice, sweets and refined snacks that need real caution. Completely banning familiar foods is hard to sustain and often unnecessary. Your dietitian can help set portions that suit your sugars and medication.
When should you see a doctor or dietitian?
Diabetes is a medical condition that needs proper diagnosis, monitoring and, for many people, medication, none of which an article can manage. Your blood glucose targets, medicines and how food fits around them should be set by your doctor and a registered dietitian, especially if you use insulin or tablets that can cause low blood sugar. See a professional promptly if your sugars are hard to control, or if you are pregnant or have other health conditions.
