Flavonoid-rich foods protect against Alzheimer’s
Berries, Apples and tea reduce the likelihood of Alzheimer’s and to suffer the related dementia diseases. The consumption of small amounts of flavonoid-rich foods, according to a recent study, useful to protect against the development of Alzheimer’s.
In the current study of the Tufts University, it was found that flavonoid-rich foods reduce the risk of developing Alzheimer’s disease. The results of the study were published in the English journal “the American Journal of Clinical Nutrition”.
2,800 people were examined for the study
The epidemiological study of 2,800 people over the age of 50 years, investigated diseases, the long-term connection between the consumption of foods containing flavonoids and the risk of Alzheimer’s disease and related dementia. While a lot of research on the connection between diet and dementia have studied over short periods of time, analyzed the new study, the exposure of over 20 years.
What flavonoids are?
Flavonoids are natural substances which occur in plants, including fruits and vegetables such as pears, Apples, berries, onions and plant based beverages such as tea and wine. Dark chocolate is another source. Flavonoids are associated with various health benefits, such as a reduction in inflammation.
Which led to a low uptake of Flavonolen?
The researchers found that a low intake of three flavonoid types with a higher dementia was associated risk. For example, a low intake of Flavonolen from Apples, pears, and tea was associated with a twice as high risk of developing Alzheimer’s disease and related dementias.
Four-fold risk of Alzheimer disease due to low consumption of blueberries and strawberries?
A low intake of so-called flavonoid polymers was associated with a twice as high risk for the development of and related dementia diseases. A lower consumption of anthocyanins, which occur, for example, in blueberries, strawberries and red wine, has even been associated with a four-fold risk for the development of Alzheimer’s and related dementia diseases.
People should take more flavonoids
The researchers analyzed a total of six types of flavonoids and compared the long-term recording with the number of later in life diagnosed diseases of Alzheimer’s and other dementias. So, they found that a low uptake (15. Percentile or lower) of three flavonoid types, compared to the highest intake (more than 60. Percentile) with a higher risk for dementia was associated.
How can be achieved a high intake of flavonoids?
A low consumption of only 15 percentile or lower means that per month, no berries (anthocyanins), about one and a half Apples per month (flavonols), and no tea (flavonoid polymers) were consumed. A high inclusion (60 percentile or higher) corresponded to about blueberries is 7.5 cups or strawberries (anthocyanins) per month, and eight Apples and pears, per month (flavonols) and 19 cups of tea per month (flavonoid polymers).
What foods are a good source of flavonoids?
Tea, especially green tea, and berries are good sources of flavonoids. Already one Cup of tea per day, or eating some of the berries two or three times per week would be sufficient to improve the values, report the researchers.
A healthy diet protects us from Alzheimer’s
Even with 50 years, the approximate age, in which the data were for the Participating for the first Time analyzed, it is too late for positive changes in the diet. There are currently no effective drugs for the treatment of Alzheimer’s disease are available, is the prevention of the disease through a healthy diet is a very important aspect, report the researchers.
