Everyday winners
Each with a reason.
- Lentils and beans: protein, fibre, folate
- Leafy greens: vitamin K, folate, lutein
- Berries and citrus fruit: vitamin C and polyphenols
- Nuts and seeds: healthy fats and magnesium
- Oily fish or flaxseed: omega-3 fats
- Curd and buttermilk: calcium and protein
- Turmeric, garlic and ginger: flavour with a possible mild benefit
- Whole grains and millets: steady energy
What to be cautious about
No food cures disease. Be wary of expensive powders and claims, and check with your doctor if you take blood thinners, since leafy greens and some supplements interact.
Foods for the brain
Leafy greens, berries, nuts, whole grains, olive oil and fish are the foundations of the MIND diet, which blends Mediterranean and DASH principles and has been associated with slower cognitive decline in observational studies. Walnuts, flaxseed and fatty fish supply omega-3 fats. Turmeric, saffron and green tea are being studied, though evidence is not yet strong. Avoid very high-sugar, high-fat processed foods, which are associated with poorer brain health.
Eat regularly, because skipping meals can affect concentration and mood.
Foods for the heart and bones
For the heart: oats, pulses, nuts, olive oil, fruit and vegetables, fish and low-fat dairy, with less salt, sugar, fried food and red meat. For bones: milk, curd, paneer, ragi, sesame, almonds, green leafy vegetables and fish with edible bones, with enough vitamin D and protein. For eyes: carrots, papaya, leafy greens and citrus fruit. For immunity: a varied, colourful diet with enough protein and zinc from pulses, nuts and seeds.
Variety is a better strategy than any single 'superfood'.
Hydration and healthy drinks
Thirst declines with age, so older adults are prone to dehydration, which causes confusion, constipation, dizziness and urinary infections. Aim for six to eight glasses of fluid a day, more in hot weather, unless your doctor restricts fluids. Water, buttermilk, coconut water, lemon water, soups and herbal teas all count. Limit sugary drinks, and keep alcohol modest or avoid it. Keep a water bottle within reach and sip through the day.
Check urine colour: pale yellow suggests good hydration.
Foods to limit or avoid
Highly processed foods, sugary drinks, sweets, deep-fried snacks, excess salt, processed meats and trans fats in some bakery products are associated with higher risk of heart disease, diabetes and some cancers. Alcohol should be limited. Be cautious of foods that interact with medicines, such as grapefruit and large amounts of leafy greens with blood thinners. Raw or undercooked eggs, meat and unpasteurised dairy carry infection risk in older adults.
Moderation and variety are the keys.
Eating for different seasons
In summer, favour cooling, hydrating foods: buttermilk, coconut water, watermelon, cucumber, curd rice and lighter meals. In monsoon, eat freshly cooked food, avoid raw salads from questionable sources and boil or filter water. In winter, enjoy warming foods such as soups, millets, sesame, jaggery in moderation and seasonal greens. Eating with the seasons offers variety and nutrients that suit the weather.
Local, seasonal food is usually the freshest and cheapest.
The evidence, food by food
Legumes lower cholesterol and blood sugar and feed gut bacteria. Leafy greens supply folate, vitamin K and lutein, linked with better brain and eye health. Berries and citrus provide vitamin C and polyphenols. Nuts reduce heart disease risk, as seen in the PREDIMED trial. Fatty fish provide omega-3 fats linked with lower heart risk. Fermented dairy offers calcium, protein and probiotics. Whole grains lower risk of diabetes and heart disease. None of these is magic, but together they form a pattern that protects.
What about turmeric, ginger and supplements?
Turmeric, ginger and garlic add flavour and have some anti-inflammatory properties in laboratory and small studies, but they are not proven treatments. Concentrated supplements can interact with medicines, for example turmeric with blood thinners. Use them as foods, in cooking, and ask your doctor before taking high-dose capsules.
Eating for immunity
Immune health depends on adequate protein, vitamins A, C, D and E, zinc and selenium, plus sleep, movement and vaccination. A varied diet usually supplies these. Test and treat deficiencies, particularly vitamin D and B12. Beware of products that claim to 'boost' immunity; a healthy immune system is balanced, not overdriven.
A shopping list for healthy ageing
Lentils, chickpeas and beans; oats, ragi and brown rice; leafy greens, carrots, tomatoes and seasonal vegetables; apples, guavas, papaya and citrus; almonds, walnuts and peanuts; curd and buttermilk; eggs and fish; olive or groundnut oil; turmeric, cumin, garlic and ginger. Keep this list on the fridge and stock up weekly.
Reading labels
Choose products with short ingredient lists. Check sodium (aim for low), added sugar (avoid when possible) and fibre (higher is better). Be sceptical of 'healthy' claims on the front of packs. Whole foods without labels, such as vegetables, lentils and nuts, are usually the best bargains.

Frequently asked questions
Is turmeric a miracle cure?
No. It adds flavour and may be mildly anti-inflammatory in a balanced diet.
Should I take omega-3 capsules?
Eating fish twice a week is better supported than capsules.
What about immunity boosters?
Good sleep, vaccination, movement and a balanced diet do more than any single product.
Is fruit juice healthy?
Whole fruit is better, since juice lacks fibre and concentrates sugar.
Are nuts safe with dentures?
Choose soft, chopped or ground nuts or nut butters.
Do I need organic food?
Eating more fruit and vegetables matters more than whether they are organic; wash produce well.
