Coffee drinking reduces dementia risk

Coffee drinking reduces dementia risk

Regular cups of tea or coffee and exercise could protect against dementia in older age, research has suggested.

Frequent tea or coffee intake and physical activity can prevent mental decline, US scientists discovered in two separate studies.

In one, the progress of 1,200 elderly men and women with an average age of 76 was looked at by Dr Zaldy Tan, from Harvard Medical School, Boston.

Health checks after an average of 10 years showed that those who engaged in moderate to heavy levels of exercise had a 40% lower risk of developing dementia than the least physically active.

The trend was more evident in men than in women, the International Conference on Alzheimer's Disease in Hawaii was told.

Professor Clive Ballard, Director of Research at the Alzheimer's Society, said: "Whether it be a round of golf, a brisk walk or a session on the treadmill, 30 minutes of exercise five times a week can be beneficial at any age."

The second study, also presented at the conference, suggested that a regular cup of tea or coffee can stave off age-related mental decline.

Scientists led by Professor Lenore Arab, from the University of California at Los Angeles, monitored 4,800 people aged over 65 for more than 14 years.

Participants who drank tea regularly were between 17% and 37% less likely to suffer a reduction in mental ability than non-tea drinkers.

People who preferred coffee were also protected. Drinking coffee more than five times a week lowered the chances of mental decline by 20%.
