Eating for Diabetes After 60

Aims of nutrition in older adults with diabetes

• Keep blood sugar in the range the doctor sets, which is often less strict for frail older adults than for younger or fit people, to avoid hypoglycaemia; see fasting and post-meal sugar readings: what the numbers mean.
• Prevent low blood sugar, especially on insulin or sulfonylureas; see low blood sugar in older adults: recognising and treating it.
• Maintain weight, muscle and strength: avoid unplanned weight loss; see malnutrition in older adults: signs and prevention.
• Protect the heart and kidneys: blood pressure, cholesterol and kidney function; see eating for heart health after 60 and eating with chronic kidney disease: a family guide.
• Keep food enjoyable and culturally familiar, so that the plan is followed.

The basic plate

A simple model for lunch and dinner, adapted from the plate method used in diabetes education and the ICMR-NIN dietary guidelines:

• Half the plate: non-starchy vegetables, cooked or raw as teeth allow: leafy greens, beans, cauliflower, cabbage, bottle gourd, ridge gourd, lady's finger, brinjal, tomato, cucumber, carrot, drumstick, mushroom.
• A quarter: protein: dal, rajma, chole, sprouts, curd, paneer, egg, fish, chicken, soya.
• A quarter: carbohydrate, preferably whole grain or millet: one or two rotis of whole wheat, jowar, bajra or ragi, or a small katori (about half to three-quarters of a cup) of cooked rice, ideally brown, red or parboiled, or millet.
• A little healthy fat: a teaspoon or two of oil (groundnut, mustard, rice bran, olive) in cooking, a few nuts.
• Water or unsweetened buttermilk to drink.

Not too little: a frail or underweight older person may need more protein and calories than this basic model suggests; the dietician adjusts.

Carbohydrates: quality, quantity and timing

Carbohydrate raises blood sugar most. Indian meals are often heavy in refined carbohydrate: large amounts of white rice, maida, sugar, sweets, biscuits, white bread and potatoes.

• Choose slower-digesting carbohydrates: whole wheat atta, millets (ragi, jowar, bajra, foxtail, kodo, little millet), oats, barley, brown or red rice, parboiled rice, whole pulses, and vegetables with fibre. Mixed-flour rotis (wheat with besan, soya or ragi) lower the load.
• Watch quantity more than type: even healthy carbohydrate in large portions raises sugar. A common target is about 45 to 60 grams of carbohydrate per main meal for many adults, but individual targets differ; ask the dietician. One roti (about 6 inch) has about 15 to 18 grams; a small katori of cooked rice has about 20 to 30 grams.
• Spread carbohydrate evenly through the day rather than a large dinner after a small lunch.
• Combine carbohydrate with protein, fibre and fat, which slows absorption: eat dal and vegetables with rice or roti, curd with fruit, nuts with a snack.
• Order of eating: some studies suggest that eating vegetables and protein first and carbohydrate last lowers the after-meal rise; it is a simple habit to try.
• Limit refined sugar and sweets, and sugary drinks, but a small portion of a sweet with a meal is not forbidden for most; see below.
• Fruit: fruit contains fibre and vitamins; eat whole fruit in modest portions (one small serving, such as a small apple, a guava, a few papaya slices, a small orange, a handful of berries or half a small banana) as part of a meal or snack rather than large amounts or juices; very sweet fruit such as mango, grapes, chikoo and ripe banana in smaller portions. Fruit juice raises sugar rapidly and is best avoided.
• Potatoes, sweet potato, yam and corn have starch; limit portions.
• Check portion sizes with measures: a katori or a cup, not by eye.

Fibre

Fibre slows sugar absorption, helps cholesterol and bowels. Aim to build up gradually to about 25 to 30 grams a day with whole grains, millets, pulses, vegetables, fruit, nuts and seeds; see 10 high-fibre foods to keep gut healthy. A psyllium husk supplement can help some people but may lower sugar further in those on insulin or sulfonylureas, and must be separated from medicines; see psyllium husk: how to take it and who should be careful. Drink adequate fluids; see hydration for older adults: how much and how to remember.

Protein

Protein does not raise sugar much and protects muscle. Older adults with diabetes often need about 1.0 to 1.2 grams per kilogram of body weight a day unless kidney disease limits it; see how much protein do older adults need and high-protein Indian meals for seniors. Include dal, pulses, eggs, dairy, fish, chicken, soya, nuts and sprouts at each meal. In kidney disease, protein targets are individualised.

Fats

Choose healthy fats: groundnut, mustard, rice bran, olive and sesame oils in small amounts (about 3 to 5 teaspoons per day for most people, as the dietician sets), nuts, seeds, oily fish. Limit ghee, butter, vanaspati, deep-fried snacks, bakery items and trans fats, which raise cholesterol and heart risk; see 7 healthy fats for cooking and when to use. Do not cut fat so low that the diet becomes unpalatable and low in calories for a thin older adult.

Salt

Many people with diabetes also have high blood pressure and kidney problems; reduce salt: less pickle, papad, namkeen, processed foods and added salt at the table; see eating for heart health after 60.

Meal timing, medicines and low sugar

Eating pattern interacts with medicines.

• Regular meal times: avoid long gaps and skipped meals, especially with insulin or sulfonylureas (such as glimepiride or gliclazide), which can cause low blood sugar.
• Never skip a meal after taking diabetes medicine without advice from the doctor; call the doctor if the person is not eating, vomiting or ill; do not stop or change medicines on your own, though the doctor may adjust doses.
• Snacks: a planned mid-morning, mid-afternoon and bedtime snack may be needed for some on insulin; the doctor advises.
• Know the signs of low sugar: shakiness, sweating, hunger, confusion, drowsiness, odd behaviour, falls. Keep fast sugar at hand (glucose tablets, sugar, juice) and follow the doctor's plan; see diabetes and low-sugar emergencies: a family plan.
• Metformin may cause stomach upset; take with meals as prescribed; long-term use can lower vitamin B12; see vitamin B12 in older vegetarians.
• Monitoring: test blood sugar as advised; see how to test blood sugar at home step by step; keep a food and sugar diary to share with the doctor.
• Illness and "sick days": when ill, vomiting or not eating, call the doctor for advice on food, fluids and medicines.

Sample day (adapt with the dietician)

Breakfast could be a moong dal or besan chilla with curd, or idlis with sambar, with a small fruit; lunch one or two rotis or a small katori of brown rice with dal, vegetables, curd and fish, chicken or paneer; an evening snack of sprouts or a guava; and a lighter, earlier dinner such as vegetable khichdi with curd. Adapt for regional diets using local pulses, millets, vegetables and fish.

Sweets, festivals and eating out

• Occasional small portions of a favourite sweet, taken after a meal with protein and fibre, are better than prolonged restriction followed by large binges; sugar-free sweets made with artificial sweeteners are not automatically healthy and often contain refined flour and fat; see 10 sugar-free sweets to enjoy a guilt-free Diwali.
• At weddings and festivals: take a small plate, fill half with salad and vegetables, choose one or two items, and skip repeated servings; check sugar afterwards.
• Fasting (vrat, Ramadan, Navratri, Ekadashi): talk to the doctor beforehand; medicines may need to be adjusted by the doctor; low sugar and dehydration are risks; see fasting, festivals and older adults: staying safe.
• Avoid "diabetic" products that are marketed with unproven claims; check labels; see how to read a supplement label.
• Herbal remedies: karela (bitter gourd) juice, fenugreek (methi), cinnamon, jamun seed powder, neem, amla and others are widely used; some can lower sugar and interact with diabetes medicines, increasing the risk of low sugar; tell the doctor, and do not replace prescribed medicines with them; see supplements and medicine interactions: a safety guide and benefits of bitter gourd.

Special situations

In frail or underweight people, relax restrictions and focus on protein and calories; see loss of appetite in older adults: causes and practical fixes. In kidney disease, protein, potassium and phosphorus limits apply; see eating with chronic kidney disease: a family guide. Walking after meals lowers sugar; see exercise with diabetes in older adults.

Red flags

Seek medical advice promptly for repeated high readings, thirst and frequent urination, unexplained weight loss, repeated lows, blurred vision, slow-healing sores, numbness or foot problems. Seek urgent help for drowsiness, confusion, fast breathing, vomiting or a very high or very low reading with symptoms; call 112.

When to ask a professional

Ask the doctor to set personal blood sugar targets and review medicines. Ask a dietician or diabetes educator for a culturally tailored meal plan with portion sizes. Ask a pharmacist about interactions, especially with supplements and herbs. Seek help for low sugar, illness, weight loss or difficulty eating.
