The research adds to evidence that Western style food is the reason why heart disease claims about 94,000 lives a year in the UK - more than any other illness

The research adds to evidence that Western style food is the reason why heart disease claims about 94,000 lives a year in the UK – more than any other illness

The Western diet really IS a killer: People who eat white bread, butter and red meat are most likely to die young 

  • Those who ate fried and unhealthy food had doubled risk of early death
  • Key culprits include red meat, white bread, butter, cream and sweet foods
  • Findings ‘help explain’ why heart disease is still the UK’s biggest killer

The typical Western diet, high in fat and sugar, really does lead to an early grave, new research suggests.

A study of more than 5,000 civil servants found those who ate the most fried and sweet food, processed and red meat, white bread and butter and cream doubled their risk of premature death or ill health in old age.

It adds to evidence that ‘Western style food’ is the reason why heart disease claims about 94,000 lives a year in the UK – more than any other illness.

The findings published in The American Journal of Medicine are based on a survey of British adults and suggest adherence to the diet increases the risk of premature death and disability later in life.

Lead researcher, Dr Tasnime Akbaraly, of the National Institute of Health and Medical Research in France, said: ‘The impact of diet on specific age-related diseases has been studied extensively, but few investigations have adopted a more holistic approach to determine the association of diet with overall health at older ages.’

She examined whether  diet, assessed in midlife, using dietary patterns and adherence to the Alternative Healthy Eating Index (AHEI), is associated with physical ageing 16 years later.

The AHEI is an index of diet quality, originally designed to provide dietary guidelines with the specific intention to combat major chronic conditions such as heart disease and diabetes.

Dr Akbaraly added: ‘We showed that following specific dietary recommendations such as the one provided by the AHEI may be useful in reducing the risk of unhealthy ageing, while avoidance of the “Western-type foods” might actually improve the possibility of achieving older ages free of chronic diseases.’

The researchers analysed data from the British Whitehall II cohort study and found following the AHEI can double the odds of reversing metabolic syndrome, a range of disorders known to cause heart disease and mortality.

They followed 3,775 men and 1,575 women from 1985-2009 with a mean age of 51 years.

Using a combination of hospital data, results of screenings conducted every five years, and registry data, investigators identified death rates and chronic diseases among participants.

At the follow up stage, just four per cent had achieved ‘ideal ageing’ – classed as being free of chronic conditions and having high performance in physical, mental and mental agility tests.

About 12 per cent had suffered a non-fatal cardiovascular event such as a stroke or heart attack, while almost three per cent had died from cardiovascular disease.

About three quarters were categorised as going through ‘normal ageing’.

The researchers said participants who hadn’t really stuck to the AHEI increased their risk of death, either from heart disease or another cause.

Those who followed a ‘Western-type diet’ consisting of fried and sweet food, processed food and red meat, refined grains, and high-fat dairy products, lowered their chances for ideal ageing.

พ่ออายุมากกลับสร้างลูกอายุยืนยาว ยิ่งเป็นแบบเดียว 2 ชั้นซ้ำยิ่งดีใหญ่

ผู้ชายที่เป็นพ่อคนเมื่ออายุมาก กลับทำให้ได้ลูกที่มีอายุยืนกว่าปกติ ยิ่งกว่านั้นหากมีปู่ ที่มีลูกเมียตอนเมื่อมีอายุแล้วเข้าด้วย ยิ่งดีใหญ่จะยิ่งได้ลูกหลานที่มีอายุยืนยาวยิ่งขึ้น

วารสาร “สมาคมวิทยาศาสตร์แห่งชาติ” ของสหรัฐฯ รายงานว่า นักวิจัยมหาวิทยาลัยนิวคาสเซิลได้รู้ข้อมูลจากการวิเคราะห์ดีเอ็นเอของหนุ่มฉกรรจ์ 1,779 คน พบว่า องค์ประกอบทางพันธุกรรมของตัวเชื้ออสุจิ ก็จะเปลี่ยนแปรไปตามอายุของเจ้าของ ซึ่งมีผลทำให้อายุยืน และจะถ่ายทอดไปถึงลูกด้วย

ผู้เชี่ยวชาญรู้มานานแล้วว่า อายุขัยขึ้นอยู่กับความยาวของส่วนปลายของโครโมโซม อันเป็นโครงสร้างทางพันธุกรรม ที่เรียกว่า “เทโลเมียร์” มีลักษณะเหมือนกับปลอกพลาสติกหุ้มปลายเชือกผูกรองเท้า ซึ่งจะสึกสั้นลงไปตามอายุ แต่ของตัวอสุจิมันกลับยาวออกไปตามอายุของเจ้าของ ยิ่งในผู้ที่มีพ่อและปู่ ที่มามีลูกเต้าเมื่อมีอายุมากแบบเดียวกันด้วยแล้ว มันจะยิ่งยาวขึ้นไปอีก.

Children with older fathers and grandfathers ‘live longer’

By Michelle RobertsHealth editor, BBC News website
12 June 2012 Last updated at 02:24 GMT

Delaying fatherhood may offer survival advantages, say US scientists who have found children with older fathers and grandfathers appear to be “genetically programmed” to live longer.

The genetic make-up of sperm changes as a man ages and develops DNA code that favours a longer life – a trait he then passes to his children.

The team found the link after analysing the DNA of 1,779 young adults.

Their work appears in Proceedings of the National Academy of Sciences.

Shoelace tips

Experts have known for some time that lifespan is linked to the length of structures known as telomeres that sit at the end of the chromosomes that house our genetic code, DNA. Generally, a shorter telomere length means a shorter life expectancy.

Like the plastic tips on shoelaces, telomeres protect chromosomal ends from damage. But in most cells, they shorten with age until the cells are no longer able to replicate.

However, scientists have discovered that in sperm, telomeres lengthen with age.

Telomeres (in red) cap the ends of chromosomes

And since men pass on their DNA to their children via sperm, these long telomeres can be inherited by the next generation.

Dr Dan Eisenberg and colleagues from the Department of Anthropology at Northwestern University studied telomere inheritance in a group of young people living in the Philippines.

Telomeres, measured in blood samples, were longer in individuals whose fathers were older when they were born.

The telomere lengthening seen with each year that the men delayed fatherhood was equal to the yearly shortening of telomere length that occurs in middle-aged adults.

Telomere lengthening was even greater if the child’s paternal grandfather had also been older when he became a father.


“Very few of the studies that linked telomere length to health in late life have studied the impact, if any, of paternal age”

Prof Thomas von ZglinickiProfessor of Cell Gerontology

Although delaying fatherhood increases the risk of miscarriage, the researchers believe there may be long-term health benefits.

Inheriting longer telomeres will be particularly beneficial for tissues and biological functions that involve rapid cell growth and turnover – such as the immune system, gut and skin – the scientists believe.

And it could have significant implications for general population health.

“As paternal ancestors delay reproduction, longer telomere length will be passed to offspring, which could allow lifespan to be extended as populations survive to reproduce at older ages.”

Prof Thomas von Zglinicki, an expert in cellular ageing at Newcastle University, said more research was needed.

“Very few of the studies that linked telomere length to health in late life have studied the impact, if any, of paternal age. It is still completely unclear whether telomere length at conception (or birth) or rate of telomere loss with age is more important for age-related morbidity and mortality risk in humans.

“The authors did not examine health status in the first generation offspring.”

It might be possible that the advantage of receiving long telomeres from an old father is more than offset by the disadvantage of higher levels of general DNA damage and mutations in sperm, he said.
