วารสาร “การแพทย์นิว อิงแลนด์” ของสหรัฐฯ รายงานว่า การศึกษาในเรื่องการดื่มกาแฟ กับคนจำนวน 400,000 คน ได้ผลว่า ผู้สูงอายุที่ดื่มกันแค่วันละ 2–3 ถ้วย มีโอกาสจะมีชีวิตต่อไปได้อีกไม่น้อยกว่า 14 ปี เหนือกว่าคนที่ไม่ดื่มหรือนานๆจะจิบที
กาแฟยังมีส่วนทำให้โอกาสที่จะเสียชีวิตจากโรคหัวใจ โรคหลอดเลือดสมอง การติดเชื้อ การบาดเจ็บ และอุบัติเหตุน้อยลงไปด้วย และแม้แต่ยังไม่อาจรู้สาเหตุชัด แต่ก็คิดว่ามันก็มีส่วนช่วยให้อายุยืนอยู่ด้วย
นักวิจัยนีล เฟรดแมน ของสถาบันสุขภาพแห่งชาติ กล่าวว่า “เรารู้ดีว่า มันมีฤทธิ์ต่อสมอง จึงอาจเป็นไปได้ว่ามันมีส่วนด้วย หรือไม่ก็อาจมีคุณต่อสุขภาพของกระดูก” เขาบอกห้ามว่า “สำหรับคอกาแฟแล้ว อย่าไปเลิก อาจจะมีบางคนบอกว่ามันไม่ดีอยู่บ้าง แต่ผมเห็นว่า มันช่วยยืนยันว่ามันไม่ได้เป็นภัย” แต่บอกต่อไปว่า “หากจะบอกว่ามันมีคุณ ก็ยังพูดไม่ได้ เพราะยังหาสาเหตุไม่เจอเหมือนกัน ผมยังไม่ได้ยุให้ใครรีบไปซดเสีย โดยหวังว่าจะได้ประโยชน์จากมัน”.

A cup of coffee can help the elderly live longer
A new study has demonstrated that drinking coffee can help the elderly live longer lives.
In a research study published in the New England Journal of Medicine, drinking coffee was linked to helping the elderly live longer lives. The study, from the National Institute of Health’s AARP Diet and Health, made the discovery by accident when the researchers were looking for links to why coffee might be unhealthy. The suggestion that drinking coffee could be risky behavior was debunked. It was found that those who drank 6 cups a day were 10 to 15 percent less likely to die than those who did not drink coffee at all. It was also noted that the more cups of coffee, the more likely one might live longer.
The study followed over 200,000 men and over 173,000 women aged 50-71 years. Excluded from the study were people with heart disease, cancer, and stroke. Although 13 percent of those who started the study passed away before it was complete, the findings were still significant.
Coffee comes from coffee trees that can grow up to 30 feet tall and live for 20 to 30 years. These trees are covered in dark green leaves that are waxy in appearance and grow in pairs. Coffee cherries grow along the huge leaves. From the flowering blossom to the complete fruit, it can take a year for the cherry to mature. The tree can live in any climate that does not have harsh fluctuations in temperature but it prefers to grow in mild climates with rich soil. Frequent rain and shady sun are also a favorite of the coffee tree.
People who are enjoying and benefiting from coffee everyday can all trace the roots of the history of coffee to the Ethiopian plateau where an ancient man took care of goats. One day he noticed that when his goats ate the cherries from a certain tree they become so full of energy they couldn’t sleep at night. Being his duty to report any strange incidents, he went directly to the abbot of his nearest monastery. The abbot then took the cherries and made them into a drink. He found it kept him awake and alert during his long evening of prayers. He then shared this with other monks. It became so popular, that soon people all over tried the new drink. The news then moved east to the Arabian peninsula where it became more commercial eventually spreading throughout the world.
While drinking several cups of coffee in this study was found to decrease a person’s risk of dying by 10 percent, experts advise that a person can become dependent on the drink and the effects of the caffeine. If trying to decrease the amount of consumption, the person should expect to have headaches. The researchers performed what was the largest analysis to date that suggested that coffee may have some health benefits. It is not known yet what helps the elderly live longer when they drink coffee, but further research may find what it is.

Caffeine fix it: How a regular cup of coffee could help you live longer
- Drinkers are less likely to die from heart disease, stroke, injuries, accidents, diabetes and infections

Too much caffeine used to be considered a bad thing. Now researchers say drinking coffee could extend your life.
They found following a study of 400,000 aged between 50 and 71, the more coffee you drink, the less likely you are to die from a number of different ailments.
These include heart disease, respiratory disease, stroke, injuries, accidents, diabetes and infections, but not cancer.
The US research published in The New England Journal of Medicine adds to evidence that coffee drinkers appear to enjoy better health.
Researchers at the National Cancer Institute, National Institutes of Health, Maryland, say they cannot establish whether coffee is the cause of a lowered risk of death, but they found a link.
The research followed a large number of people, 229,000 men and 173,000 women, taking part in a diet and health study between 1995 and 2008.
Participants were classified according to the amount of coffee they drank at the start of the study, into groups drinking up to six cups a day or more, and non-coffee drinkers.
There were 52,000 deaths during the period, with an ‘inverse association’ between coffee consumption and death.
This means those drinking greater amounts of coffee had an ever reducing risk of dying.
About one third of coffee drinkers were consuming decaffeinated coffee and the findings held for this group.
Experts say for this reason it is unlikely it is the caffeine ingredient giving health benefits, but there are known direct biological effects from antioxidants and magnesium contained in coffee.
Dr Euan Paul, executive director of the British Coffee Association said ‘This important research adds to the overwhelming weight of evidence which demonstrates that moderate coffee consumption of 4-5 cups of coffee per day is safe and may be associated with certain health benefits.
‘Whilst more research is required to determine whether the inverse association seen in this study is causal, these results are particularly encouraging because they build on previous research which has also suggested an inverse association between coffee consumption and total and cause-specific mortality.
‘Pregnant women should continue to moderate their caffeine intake to 200mg per day in line with NHS guidelines.’
