What if one of the biggest drivers of age-related health problems isn’t a specific disease at all — but a quiet, invisible process happening in your body right now? Chronic low-grade inflammation, sometimes called “inflammageing,” is increasingly recognised as a key factor behind many of the conditions we associate with getting older. The good news? There’s a great deal you can do about it.
TL;DR
- Chronic low-grade inflammation (“inflammageing”) is linked to heart disease, type 2 diabetes, arthritis, cognitive decline, and other age-related conditions
- Unlike acute inflammation (which heals injuries), inflammageing is a persistent, low-level process that accelerates ageing
- An anti-inflammatory diet rich in oily fish, vegetables, berries, and wholegrains — alongside regular movement — can significantly reduce inflammatory markers
- TILDA research shows that inflammatory markers like CRP are common in Irish older adults and linked to poorer health outcomes
- Practical lifestyle changes including sleep, stress management, and social connection all help manage chronic inflammation
What Is Inflammageing?
Most of us are familiar with acute inflammation — the redness and swelling around a cut or sprained ankle. That’s your immune system doing its job, rushing to repair damage. It’s short-lived and essential.
Inflammageing is something different. It’s a chronic, low-grade inflammatory state that develops gradually as we age. Your immune system becomes slightly overactive, producing small amounts of inflammatory chemicals (like C-reactive protein, or CRP, and interleukin-6) even when there’s no injury or infection to fight.
Over time, this low-level inflammation can damage tissues and organs, contributing to conditions such as cardiovascular disease, type 2 diabetes, osteoarthritis, Alzheimer’s disease, and even some cancers. Research from the Irish Longitudinal Study on Ageing (TILDA) at Trinity College Dublin has found that elevated CRP levels are common among Irish adults over 50 and are associated with reduced physical function and poorer overall health.
What Causes Chronic Inflammation?
Several factors contribute to inflammageing, and many of them are within your control:
Diet: A diet high in ultra-processed foods, refined sugars, and saturated fats promotes inflammation. The typical Western diet, unfortunately, tends to be pro-inflammatory.
Physical inactivity: Sedentary behaviour is strongly linked to higher inflammatory markers. Muscle tissue, when used regularly, actually produces anti-inflammatory substances.
Excess body fat: Visceral fat (the fat around your organs) is particularly problematic — it actively produces inflammatory chemicals. Even modest weight loss can reduce inflammation significantly.
Poor sleep: Disrupted or insufficient sleep raises inflammatory markers. Adults over 50 who consistently sleep fewer than six hours show higher levels of CRP.
Chronic stress: Prolonged stress keeps your body in a state of heightened alert, which promotes inflammation. This is one reason why mental wellbeing and physical health are so closely connected.
Smoking and excess alcohol: Both are powerful drivers of inflammation. Ireland’s HSE provides free supports for quitting smoking (Freephone 1800 201 203) and managing alcohol intake.
The Anti-Inflammatory Plate: What to Eat
One of the most effective tools against chronic inflammation is your diet. The Mediterranean-style eating pattern has the strongest evidence base, and it translates well to Irish ingredients and tastes.
Fill up on:
- Oily fish — salmon, mackerel, sardines (aim for two portions a week). Irish waters produce excellent mackerel and salmon rich in omega-3 fatty acids, which are potently anti-inflammatory.
- Colourful vegetables and fruit — berries, leafy greens, tomatoes, peppers, beetroot. The deeper the colour, the higher the antioxidant content.
- Wholegrains — porridge oats (an Irish staple), brown bread, brown rice. These provide fibre that feeds beneficial gut bacteria, which in turn help regulate inflammation.
- Nuts and seeds — walnuts, almonds, flaxseeds. A small handful daily provides healthy fats and vitamin E.
- Olive oil — use as your main cooking oil. It contains oleocanthal, a compound with anti-inflammatory effects similar to ibuprofen.
- Herbs and spices — turmeric, ginger, garlic, and rosemary all have documented anti-inflammatory properties.
Cut back on:
- Ultra-processed foods, sugary drinks, and excess red meat
- Refined carbohydrates (white bread, pastries)
- Foods high in trans fats
You don’t need to overhaul your diet overnight. Even small, consistent changes — swapping white bread for wholemeal, adding a portion of oily fish each week, choosing berries over biscuits — can measurably reduce inflammatory markers over time.
Movement Is Medicine
Regular physical activity is one of the most powerful anti-inflammatory interventions available. When you exercise, your muscles release myokines — proteins that actively reduce inflammation throughout your body.
The WHO recommends at least 150 minutes of moderate-intensity activity per week for adults over 65, plus muscle-strengthening activities on two or more days. But any movement counts. Walking, swimming, cycling, gardening, dancing — they all help.
Ireland offers wonderful opportunities for staying active at every age. Get Ireland Walking coordinates free walking groups nationwide, many local leisure centres offer over-50s swim sessions, and organisations like Active Retirement Ireland run exercise programmes in communities across the country. Even a daily 30-minute walk along one of Ireland’s Slí na Sláinte marked trails makes a meaningful difference.
Sleep, Stress, and Social Connection
Managing inflammation isn’t only about diet and exercise. Three often-overlooked factors play a crucial role:
Sleep: Aim for seven to eight hours of quality sleep. If you’re struggling, speak to your GP — sleep problems after 50 are common and treatable. Good sleep hygiene (consistent bedtime, cool room, limiting screens before bed) can make a real difference.
Stress management: Chronic stress keeps cortisol elevated, which promotes inflammation. Mindfulness, meditation, time in nature, and creative activities all help lower stress hormones. Many community centres and ETBs around Ireland offer free or low-cost mindfulness courses.
Social connection: Loneliness and social isolation are associated with increased inflammatory markers — TILDA research has specifically documented this link among Irish older adults. Staying connected through community groups, volunteering, Active Retirement Ireland branches, Men’s Sheds, or even regular phone calls with friends and family is genuinely good for your physical health.
When to Talk to Your GP
If you’re concerned about inflammation, your GP can check your CRP levels with a simple blood test. This is particularly worthwhile if you have a family history of heart disease, diabetes, or autoimmune conditions, or if you’re managing an existing chronic condition.
Your GP can also help identify any underlying causes of inflammation and connect you with appropriate supports — whether that’s a referral to a dietitian through the HSE, a community exercise programme, or help with sleep or stress management.
Under the HSE’s Chronic Disease Management Programme, adults with conditions linked to inflammation (such as cardiovascular disease, COPD, or diabetes) can access structured reviews with their GP at no additional cost if they hold a medical card or GP visit card.
Small Changes, Real Results
Inflammageing isn’t something you can see or feel day to day, but addressing it can have a profound impact on how well you age. The encouraging message from the research is clear: lifestyle changes work, and it’s never too late to start.
You don’t need a radical transformation. Start with one change this week — perhaps an extra portion of oily fish, a daily walk, or a commitment to better sleep. Build from there. Over weeks and months, these small adjustments compound into measurable reductions in inflammation and real improvements in how you feel.
At Críonna Health, we believe that understanding the science behind healthy ageing empowers you to make informed choices. Inflammageing may be a natural part of getting older, but how much it affects your health is largely up to you.
