What is required to stay healthy as you age? More often than not, the answer to that comes in fragments: eat better, move more, maybe take up crosswords.
All true - and all somewhat beside the point. Healthy ageing isn't really due to any single habit performed brilliantly. It's about five separate areas:
-
Nutrition
-
Movement
-
Mental wellbeing
-
Preventive care and
-
Social connection
each pulling in roughly the same direction.
None of them will do enough on their own, which is worth knowing before diving into any one of them individually. Someone who eats well but never sees another soul, or exercises diligently but skips every health check, is still leaving a fair amount of their longevity journey entirely up to chance.
But before we go further, and although it is NEVER too late to take action, you should know that the ideal time to act on healthy ageing is in your 40’s and 50’s. Because that lays the foundation for health in your 60s and 70’s.
Nutrition: the foundation, not the whole house
Food gets more attention than almost anything else when it comes to healthy ageing, and reasonably so: nutrition is at the base of everything. A diet built around vegetables, olive oil, fish and wholegrains - in short, the Mediterranean diet is consistently linked with lower rates of heart disease, better blood sugar control, and reduced inflammation. It isn't a magic bullet on its own, but it's difficult to age well without it.
Movement: less about the gym, more about daily life
Exercise does more than protect the heart. Regular physical activity preserves the muscle mass and balance that keep everyday independence intact, walking upstairs, carrying shopping, getting up off the floor without a production number.
It will also help improve sleep quality, which in turn makes it easier to stick with everything else on this list; poor sleep and low activity levels have excellent chances of dragging each other - and you - down together.
We’ve covered the healthy lifestyle habits that support this, including how much exercise makes a measurable difference and how sleep fits into the picture in more detail at the link, but the short version is that consistency beats intensity by a wide margin.
Purpose does more than people expect
Brain health and mental wellbeing usually get treated as separate from physical ageing, which undersells both. A genuine sense of purpose - ikigai in Japanese, "a reason to get up in the morning" - has been linked to a 46% lower risk of mortality over the following four years in people who report the strongest sense of it, a figure that rivals the impact of not smoking.
Staying mentally engaged matters just as much. Learning new skills, taking on projects, staying curious rather than coasting, gardening, all appear to support what researchers call neural plasticity - which is the brain's ongoing ability to form new connections well into later life. It's not just a matter of doing puzzles for the sake of it or to pass time; it means staying involved in things that genuinely require thought.
The checks people skip when they feel fine
It's easy to assume prevention only matters once something's gone wrong. In practice, the opposite is true: catching problems early is what keeps them small, and it's an area people are often surprisingly casual about - particularly once they feel perfectly well.
In England, adults aged 40 to 74 without an existing cardiovascular condition are entitled to a free NHS Health Check every five years, covering blood pressure, cholesterol and diabetes risk. Cervical, breast and bowel screening programmes catch the kind of early-stage changes that are far easier to treat than late-stage ones. Annual flu vaccination matters more with age, given that a weakened immune response tends to accelerate other forms of decline.
Hearing checks belong on this list too, more than most people assume. Cognitive decline appears two to three times more common in people with untreated hearing loss who also lack regular social contact - which brings this full circle to the final pillar.
The pillar that's easiest to neglect
Staying regularly in touch with family, friends and neighbours isn't just pleasant: it appears to be genuinely good for you, particularly in terms of cognitive health. This is one of the clearer threads running through what is true of people who live to 100: strong, regular social ties show up again and again as one of the more consistent habits behind healthy longevity, right alongside diet and movement rather than trailing behind them.
Putting the five together
None of this requires a complete life overhaul, and nobody manages all five pillars perfectly all the time. What the evidence consistently favours is breadth over intensity: eating reasonably well most days, staying on your feet regularly, keeping something to look forward to, turning up to the check-ups, and keeping people in your life. Small, unglamorous, everyday things.
That, more than any single supplement or superfood, is what staying healthy as you age looks like: five ordinary habits, all important, working together for the common goal of living a long, healthy life.
Part of a Series
This article is part of series on staying healthy as you get older and improving your quality of life.
It’s not only a goal almost everyone shares, but has huge implications on national healthcare spending, productivity and economic resilience.
It strongly recommends the Mediterranean diet as the best way of eating but recognises that maintaining strength and aerobic fitness is also a critical part of a healthy ageing lifestyle.
It also suggests a supplement to help reach the increased plant nutrient levels that you need as you get older.
DailyColours® contains 161 plant nutrients – nutrients that are missing from an ordinary vitamin and mineral pill. Clinical trials show that it offers Mediterranean diet benefits in a daily supplement. You can see it here.
