Top New Travel Videos: “Istanbul” By Eliane Hajj

Filmed and Edited by: Eliane Hajj

Istanbul, formerly known as Byzantium and Constantinople, is the most populous city in Turkey and the country’s economic, cultural and historic center. Istanbul is a transcontinental city in Eurasia, straddling the Bosporus strait (which separates Europe and Asia) between the Sea of Marmara and the Black Sea. Its commercial and historical center lies on the European side and about a third of its population lives in suburbs on the Asian side of the Bosporus. With a total population of around fifteen million residents in its metropolitan area, Istanbul is one of the world’s largest cities, ranking as the world’s fifth-largest city proper and the largest city in Europe.

 

Brain Health Studies: Blueberries, Flavonoid-Rich Foods Lower Risks Of Alzheimer’s And Dementia

From the American Journal of Clinical Nutrition (April 22, 2020):

FlavonoidsOur findings imply that higher long-term dietary intakes of flavonoids are associated with lower risks of ADRD and AD in US adults.

Our findings provide new evidence that diets higher in flavonols, anthocyanins, and flavonoid polymers are associated with a lower risk of developing ADRD. These associations were sustained after accounting for a variety of potential confounders including key nutrients related to ADRD risk and overall diet quality. Similar findings were seen with AD risk for flavonols and anthocyanins but the association with flavonoid polymers was no longer statistically significant.

Along with improvements in healthcare and medical technology, the aging of the baby boom generation will result in an unprecedented rise in the number of older Americans (12). Currently, there are >50 million Americans aged ≥65 y, and that is projected to more than double by 2060 (3). A consequence of this increase in older adults is the escalation of age-related diseases (45). Alzheimer disease (AD) and related dementias (ADRD), a group of symptoms in which there is progressive deterioration in cognitive function severe enough to interfere with a person’s daily living activities, are regarded as among the most significant public health challenges largely affecting adults aged >65 y (6). AD is the most common form of dementia, making up ∼60–80% of dementia cases. Currently, 5.8 million Americans are living with AD, and by 2050 that is projected to escalate to 14 million (7).

Travel & Wellness Books: “Be Well” By Kari Molvar

Be Well - Gestalten BookBe Well delves into one of life’s greatest pleasures; a day spent rejuvenating the body and nourishing the spirit. Humans have practiced self-care for centuries—in the sweat lodges of the American Southwest, Roman baths, the hammams of the Ottoman Empire, Japanese onsens, and Finnish saunas. Today, a new interest in self-care is redefining how we accomplish wellness, and there have never been more options.

 

In our increasingly switched-on lives, a growing industry of highly choreographed experiences is geared to help us switch off. Be Well is a journey around the world’s most extraordinary spaces for achieving this, looking at the innovative practices they offer and how to carry them into everyday life.
