What you eat could be your most powerful weapon against daily pain – here’s where to start

Nobody tells you that the daily management of pain becomes one of the quiet preoccupations of life after 60. The knee that aches getting out of bed. The migraine that derails a morning. The digestive discomfort that makes social eating feel like a minefield. These are not dramatic complaints – they are the background noise of an ageing body, steady and persistent and quietly exhausting.

The medical system has answers for many of them. But there is a simpler tool that is consistently underestimated, available to most of us three times a day, and increasingly supported by serious science: food.

The relationship between what we eat and how we feel is more direct than most people realise. Inflammation, nerve sensitivity, gut health and brain chemistry are all influenced, meal by meal, by the choices on our plate. None of this is a substitute for medical advice or prescribed treatment. But for the millions of Australians managing migraines, joint pain or irritable bowel syndrome, the right dietary changes can meaningfully reduce the frequency and intensity of symptoms – sometimes dramatically.

Here is what the evidence actually says.

Migraines: feed your brain, calm the storm

Migraine is far more than a bad headache. It is a neurological event – and for the one in seven Australians who experience them, finding reliable prevention is a constant project.

Recent clinical reviews support anti-inflammatory and mitochondrial-supporting dietary approaches for migraine prevention, with particular emphasis on magnesium, riboflavin (vitamin B2), omega-3 fatty acids and coenzyme Q10. What does that look like on a plate?

Fatty fish – salmon, sardines, mackerel, tuna. Omega-3 fatty acids show prophylactic benefit in randomised trials and network meta-analyses for migraine, with favourable tolerability. Aim for two to three serves per week.

Leafy greens and legumes. These are rich in magnesium and folate – two nutrients strongly linked to migraine frequency. Spinach, kale, lentils and chickpeas are practical daily options.

Whole grains over refined carbohydrates. Increased consumption of whole-grain bread and whole-grain pasta, combined with decreased intake of white bread, showed a statistically significant correlation with a reduction in both migraine attack frequency and the use of rescue medications per month. Swap white bread, white rice and processed cereals for oats, brown rice, quinoa and whole-grain alternatives.

Nuts and seeds. Almonds, sunflower seeds and pumpkin seeds are excellent sources of magnesium. A small handful daily is an easy addition that adds up.

Water – consistently. Dehydration is one of the most reliably identified migraine triggers. Eight glasses a day is the baseline; more on hot days or after exercise.

Higher adherence to a Mediterranean-style diet overall is associated with lower migraine frequency and disability in observational studies – so rather than focusing on individual foods, think of the pattern: more fish, more vegetables, more whole grains, less processed food, less sugar.

Joint pain: fight fire with food

When joints ache – whether from osteoarthritis, rheumatoid arthritis or general inflammation – what is happening inside the body is an inflammatory process. And inflammation, it turns out, is significantly influenced by diet.

Most of the foods that positively impact inflammation are plant foods containing nutrients and plant chemicals that appear to reduce inflammation, including antioxidants, fibre and omega-3 fatty acids.

Fatty fish, again. Fatty fish such as salmon, mackerel, sardines and trout are excellent sources of omega-3 fatty acids, which have been shown to reduce joint stiffness, swelling and pain. The Arthritis Foundation recommends 600 to 1,000mg of fish oil daily for those with joint pain.

Extra virgin olive oil. Olive oil contains a compound called oleocanthal, which scientists have determined has similar anti-inflammatory qualities to NSAIDs like ibuprofen. Replacing butter and other saturated fats with good olive oil is one of the simplest dietary upgrades you can make.

Berries – especially cherries, blueberries and strawberries. Blueberries and strawberries have been found to reduce inflammation markers by 10 to 15 per cent in individuals with arthritis. The deep red and purple pigments are anthocyanins – potent antioxidants that target inflammatory pathways directly.

Turmeric and ginger. Both have well-documented anti-inflammatory properties. Turmeric’s active compound, curcumin, has been shown to reduce inflammation and joint pain in multiple studies. Add them to curries, smoothies, soups or warm drinks.

Nuts. A study found that people who ate the most nuts over 15 years had a 51 per cent lower chance of inflammation. Walnuts, almonds and Brazil nuts are particularly useful.

Broccoli and other cruciferous vegetables. Broccoli contains sulforaphane, a compound that research suggests may slow the progression of osteoarthritis. It is also rich in vitamin C, which supports collagen and cartilage health.

The broader pattern matters here too. The Mediterranean and DASH diets, which limit added sugar, refined carbohydrates and saturated fat, are anti-inflammatory standouts recommended for arthritis management.

IBS: gentle food for a sensitive gut

Irritable bowel syndrome affects up to 30 per cent of Australians and is one of the most common reasons people seek medical attention. The cramping, bloating, unpredictable bowel habits and discomfort it causes can significantly curtail daily life. The good news is that dietary management is one of the most effective tools available.

The key insight from current research is that IBS is highly individual. What triggers symptoms in one person may be well-tolerated by another. That said, several dietary strategies have solid evidence behind them.

The low-FODMAP approach. The low-FODMAP diet involves temporarily restricting short-chain carbohydrates that are poorly digested in the small intestine and then fermented by gut bacteria in the colon, triggering gas, bloating and abdominal pain in sensitive individuals. Common high-FODMAP foods include garlic, onion, apples, milk, mushrooms and wheat bread. Working with an accredited dietitian to identify your personal triggers is the recommended approach – this is not a permanent elimination but a structured process of identification and reintroduction.

Soluble fibre. General dietary tips for IBS include eating more high-fibre foods like fruit and vegetables, legumes and whole grains. Soluble fibre – found in oats, psyllium, carrots, bananas and sweet potato – is particularly gentle on the gut, helping to regulate bowel movements without the fermentation that insoluble fibre can trigger in sensitive individuals.

Fermented foods – yoghurt, kefir, miso. Fermented products such as yoghurt and kefir target the gut microbiota by promoting microbial diversity and improving gut barrier function and immune modulation. A daily serve of plain, live-culture yoghurt is a simple and practical starting point.

Peppermint. Peppermint oil is a well-established treatment included in IBS guidelines due to its antispasmodic effect on intestinal smooth muscle, which reduces abdominal pain and discomfort. Peppermint tea after meals is a gentle, food-based version of this.

The Mediterranean diet. There is growing evidence that a Mediterranean diet – which focuses on extra virgin olive oil, fruit, vegetables, whole grains, nuts and seeds, fish and small quantities of red meat – may reduce IBS symptoms and has also shown benefit for the depression that frequently accompanies IBS, via its effect on the gut microbiome.

The pattern that connects all three

Look across these three conditions and a consistent picture emerges: more fish, more colourful vegetables, more whole grains, more olive oil, less processed food, less sugar. This is broadly the Mediterranean dietary pattern – and it appears in the evidence for migraine, joint pain and IBS alike.

That is not a coincidence. The common thread is inflammation and gut health, two systems that are influenced by every meal. You do not need to overhaul your kitchen overnight. Adding one or two of these foods each week, and gradually reducing the processed foods that work against them, is a practical and sustainable way to start.

Talk to your doctor before making significant dietary changes, particularly if you take blood thinners or other medications that can be affected by certain foods. And if symptoms are severe or worsening, a referral to an accredited dietitian is well worth asking for.

Food won’t fix everything. But for many people, it fixes more than they expect.
