In the AJADD study, after institutionalized AD patients consumed two 4-oz glasses of apple juice a day for a month, their caregivers reported no change in the patients’ Dementia Rating Scale or their day-to-day abilities. What did change, however, was the behavioral and psychotic symptoms associated with their dementia (as quantified by the Neuropsychiatric Inventory), with approximately 27% improvement, mostly in the areas related to anxiety, agitation, and delusion.

Alzheimer’s disease is characterized by a progressive loss of memory, decline in cognitive function, behavioral changes, and the loss in ability to do daily activities, all of which causes a significant caregiver burden and increased health care costs. While pharmacological treatments can provide temporary reduction in AD symptoms, they’re costly and cannot prevent the ultimate decline in cognitive and behavioral function. That’s why the authors considered it important to discover any possible nutritional interventions.

“The modest, but statistically significant, impact of apple juice on the behavioral and psychological symptoms of dementia in this study adds to the body of evidence supporting the usefulness of nutritional approaches, including fruit and vegetable juices, in delaying the onset and progression of Alzheimer’s Disease, even in the face of known genetic risk factors,” write the authors, Ruth Remington, RN, PhD, Amy Chan, PhD, Alicia Lepore, MS, Elizabeth Kotlya, MS, and Thomas B. Shea, PhD, “As in prior studies with vitamin supplements, it indicates that nutritional supplementation can be effective even during the late stages of AD.” redOrbit

“It’s an exciting category right now,” says Arthur Gallego, spokesman for Vita Coco, which recently got an endorsement from pop singer Madonna.

Coconut water — the liquid found in green, i.e. young, coconuts — has been popular in tropical countries ever since someone figured out how to crack that nut. And it has been available in packaged form in ethnic markets and natural food stores for some time in the United States.

But now it is showing up in mainstream supermarkets, packaged in juice-box style packages and coming in an array of flavors, such as peach-mango and tangerine.

“What is incredible to see is that the consumption of coconut water has trickled down from the natural food stores to the mainstream,” says Rodrigo Veloso, founder and CEO of Los Angeles-based O.N.E., One Natural Experience, makers of O.N.E. Coconut Water.

Veloso’s company is bringing out O.N.E. Active, which sports fewer calories than its regular coconut water and adds ginkgo biloba, ginseng and catuaba. It comes in three flavors, including lemon-lime.

Yes, it is true. They are putting the lime in the coconut.

Already, coconut water has created some big-name buzz.

Besides Madonna, Matthew McConaughey and Demi Moore recently invested in Vita Coco, which was founded in 2004 and saw sales jump from about $4 million in 2007 to $20 million in 2009, according to Gallego. Meanwhile, Pepsi has invested in O.N.E. A third company in the market is Zico, founded in 2004.

While coconut water sales are growing, in the $40 million to $60 million range annually, they remain a drop in the bucket compared to billion-dollar drink brands like Red Bull, says Jeffrey Klineman, editor of Bevnet.com, an online review about nonalcoholic beverages.

“It’s definitely got people excited, but we don’t know how big it will be when it reaches the plateau,” Klineman says. “The question is, is it a nine-figure plateau or a billion-dollar plateau? Whether they become part of the beverage firmament is still not really settled.”

Fans of coconut water praise it for being relatively low calorie, natural and packed with important nutrients. An 11.2-ounce serving of Vita Coco contains almost 700 milligrams of potassium, more than a banana.

That is a good thing for Americans, who are fruit-and-veggie-shy and often do not get enough potassium, says Andrea Giancoli, registered dietitian and spokeswoman for the American Dietetic Association. At about 60 calories for an 11-ounce serving of plain coconut water, a little more for the flavored versions, the drink delivers good nutritional value. Still, not that many people exercise with the intensity that requires more than plain water for rehydration and some are not exercising at all, she points out.

“It’s perfectly fine to incorporate into part of your diet if you’re balancing out the rest of your diet, but I wouldn’t believe all the hype,” she says. “We live in this world where we’re always trying to find the answer to health and the answer to weight. It still takes good old-fashioned exercise and healthy eating.”
