There are lots of reasons why some individuals live long healthy and balanced lives while others don’t, however one of them is undoubtedly genes. That doesn’t mean we must be negative about our chances of ageing in good health. Even though our genes are handed down from our parents, the hand that we are dealt appears to be influenced by our lifestyle, too. Food, physical activity and tension can easily modification how genes function by adding “chemical tags” that act as on/off or dimmer switches, influencing our health and lifespan. The study of this process is known as epigenetics.
In a collection of research studies along with nonagenarians that were in robust health (the BELFAST studies), we found that participants carried fewer of the genes that are implicated in cardiovascular disease and showed some gene types which may have actually helped boost their immunity.
In the most recent BELFAST nonagenarians’ study, we built on these findings and asked energetic nonagenarians why they believed they had lived for so long and in such good health. Family history and personal stories are powerful tools as soon as used in parallel along with genomic analyses. They can easily recommendations us to understand how our beliefs, behaviour and lifestyle choices subtly fine-tune how our genes function in day-to-day life.
By talking to nonagenarians about their lives, we identified how important they considered their genes to be, however they likewise told us about several various other factors that they believed supported their long and healthy and balanced lives.
Genes and good health
Nonagenarian siblings recognised genes as important. Ellie, 99, said: “I suppose it was the family I was born in to – my mother’s female relatives all seemed to live in to their 90s. I can easily remember cousins and aunts, all were over 90.”
She added: “The men didn’t live so long.”
In fact, Ellie had observed something scientists still don’t understand: why women live longer compared to men. Evidence suggests that it may relate to male hormones in the womb leading to increased age-related disease.
Train physique and mind
All of the individuals in our study spoke about the importance of keeping mentally and physically active. Robert, a shopkeeper, said: “Hard job all my life. I believe that is the secret.”
Norman, 95, one of two nonagenarian brothers, both railwaymen, said: “I left school at 16 and, yes, we had to go to job then. It wasn’t like today as soon as you can easily keep your education going until you are 23 or 24.” His brother, Joyce, 96, agreed: “Yes we worked hard. There is no doubt about it.”
Samuel, 95, however “going on 25”, keeps mentally busy and told us that he had simply finished writing his tenth book.
The health benefits of physical activity are hard to ignore. Regular exercise changes our epigenome, activating genes that improve muscle function. Exercise not only protects our muscles however likewise our brains along with a possible dose-related effect – the more we do, the greater the effect. Exercise is great for everyone and it’s never too late to start.
Eat well
Many of the study participants mentioned the importance of Meals in ageing well. Norman said: “I have actually always led a quiet life. Didn’t smoke or drink to any extent and was always fed on good solid food. No junk food.” His brother, Joyce, added: “We always had sensible food. Never smoked, except for a couple of months.”
Eileen, 92, gave details of “good food, good healthy and balanced meals. Mama would certainly have actually a big pot of broth for us.”
There is truth in the saying: you are exactly what you eat. Scientists have actually provided evidence that fruit and vegetables may dampen cancer-causing genes, or may protect us from cancer by altering epigenetic markers.
Few participants smoked, avoiding the known epigenetic effects of cigarette smoke including lung damage, increased risk of dementia and cancer.
Be positive, stay social
Many of the participants described “being happy”, “always cheerful”, “never melancholy” and being content along with a “rich life” and family relationships. Typical examples from siblings include Samuel, 95, that said he is “interested in people, interested in life”. His sister Ethel, 93, added: “[I am] interested in things, and everything that’s going on.” Whilst Sarah, 95, one of two sisters, told us: “Oh, I am always happy” and her sister Mariah, 94, said: “I have actually simply a happy disposition”.
The ability or willingness to cope along with difficulties was an additional common attitude we observed. As Eileen, 96, told us: “[I] simply take points as they come.”
Successful ageing is considered to be more compared to the absence of disease and being able to live independently however involves being socially active. Friends and family are important factors in ageing well, making for good mental health, reasonable risk of premature death and can easily recommendations individuals deal along with stressful events in their lives.
The epigenetic adjustment of our genes – and the life stories of healthy and balanced nonagenarians – offer explanations about how diet, physical activity, tension and exposure to toxins and infections can easily subtly alter our genes and our predisposition to disease.
The key to ageing well may not depend on choosing our parents wisely (even if we could), however making good lifestyle choices.
