Study shows fruit juice benefits

A diet rich in fruit juice could cut the risk of Alzheimer's disease and other diseases, according to research.
A team at Glasgow University has carried out one of the first studies into the benefits of antioxidants.
The study found that grape, apple and cranberry juices contained high amounts of the beneficial chemicals.
Antioxidants are natural chemicals which reduce cell damage caused by free radicals, a major cause of disease and ageing.
Researchers from the Human Nutrition group at Glasgow University examined different juices and how much antioxidant they contained as well as the different chemical compounds.
Polyphenols are a very strong antioxidant that get rid of free radicals in the body.
It is believed they can maintain and improve health and also protect against chronic diseases.

Diet high in cholesterol can trigger onset of Alzheimer's, warn scientists

An unhealthy diet filled with high-cholesterol foods can increase your risk of Alzheimer's Disease, say scientists.

Studies have found that eating lots of foods containing saturated fats, such as butter and red meat, can boost levels of proteins in the brain linked to dementia. Now scientists have discovered this may be because such a diet affects cholesterol-clearing substances in the brain.

They hope the discovery could lead to new drugs which allow the clogging fats to be cleared more effectively and so help slow down the progression of the debilitating brain condition.

In Britain 500,000 people have Alzheimer's Disease in which the progressive loss of their brain cells leads to memory loss, mood changes and eventually death.
One of the key characteristics of people with the condition is the formation of clumps, or 'plaques' of beta amyloid proteins which are thought to destroy brain cells.

Scientists increasingly believe diet and lifestyle may affect the build up of these damaging proteins.

Studies have found a Mediterranean-style diet rich in plant foods and fish and low in red meat cuts the risk of developing the brain disease by up to two-thirds.
Research in mice has also found that those given high-cholesterol diets have more amyloid beta proteins in their brain.

And there is growing evidence that taking cholesterol-lowering statins makes people less likely to develop Alzheimer's later in life.

How three cups of coffee can cut Alzheimer's risk

DRINKING three cups of coffee a day can significantly reduce the chance of developing Alzheimer's disease, say researchers.
A ten-year study of 600 elderly men found those getting a regular caffeine fix experienced a much smaller decline in their mental abilities than non coffee-drinkers. Researchers believe caffeine may trigger a chain reaction in the brain that prevents the damage of Alzheimer's.
In a report on their findings, published in the European Journal of Clinical Nutrition, they raised the possibility that doctors may one day recommend coffee to the elderly.
"Drinking three cups a day was associated with the smallest cognitive decline," they said."
Alzheimer's affects an estimated 750,000 people in the UK.
Most die within ten years of being diagnosed, and the cost of caring for victims is more than for stroke, heart disease and cancer put together.
