Berries, apples and tea can do wonders for your brain

If you'e looking for an easy way to keep your brain healthy, consider eating more berries, consuming more applies and drinking tea. There's good science to support the benefits of getting started early eating a healthy diet for preventing Alzheimer's disease and other forms of dementia. 
Alzheimer's risk significantly lower for older adults who consume these foods
Tufts University scientists looked at Alzheimer's disease risk among older adults and compared those that consumed scant amounts of apples, tea and berries that are loaded with antioxidants; published in the Journal of Clinical Nutrition. 
The study finding was based on conclusions extracted from dietary questionairres submitted during medical exams among heart disease risk patients participating in the Framingham Heart Study. 
One of the important highlights of this study, compared to others is that the risk of the brain disease was analyzed over a 20 year period, versus short term studies that have been pub…

Tiny vitamin in milk found to have remarkable health benefits

Researchers have discovered a small,  hidden vitamin in milk that has remarkable health benefits. The finding comes from mouse studies. Scientists discovered that high doses of a novel form of vitamin B3 that is present in small quantities in milk, and possibly other foods, makes mice stronger, faster and leaner without dieting and without exercise.
Hidden milk vitamin could prevent obesity and type 2 diabetes
Though the researchers aren’t sure about the human effects of the form of vitamin B3 -nicotinamide riboside or NR - which is a cousin to a precursor of the B vitamin Niacin, they now understand there are some potential benefits for preventing obesity and even type 2 diabetes.
In the mouse study, nicotinamide riboside offered the same benefits for health as eating a low-calorie diet and exercise, but the mice didn’t have to do either.
Dr. Anthony Sauve, associate professor of Pharmacology at Weill Cornell Medical College where the study was conducted explained in a press release:

How sleep deprivation alters the brain to raise anxiety

New information from sleep experts links too little sleep to higher anxiety levels. People who are already nervous have trouble sleeping. Conversely, lack of sleep can make already nervous people even more anxious, supercharging emotional responses from altered brain processes.

Lack of sleep triggers emotional brain centers
Researchers from theSleep and Neuroimaging Laboratory at the University of California, Berkeley used MRI's of the brain to find how lack of sleep triggers emotional centers in the brain; in particular, the amygdala that reacts to unpleasant events.

For the study, investigators performed functional MRI (fMRI) on 16 subjects: once after sleep deprivation and once after a good night’s sleep. They were shown either an unpleasant or neutral image while scientists looked at what happened in the brain.
For some of the study participants, sleep deprivation increased the anticipation of a negative event as much as 60 percent.
"Anticipation is a fundamental brain proces…

Ginseng gives cancer patients an energy boost in Mayo Clinic study (VIDEO)

Ginseng has long been used in Chinese medicine to boost energy. Now researchers at Mayo Clinic have found high doses of American ginseng (Panax quinquefolius) can give cancer patients suffering from fatigue that accompanies chemotherapy an energy boost.
For their study, the researchers tested primarily breast cancer patients (60 percent of participants).  Included were 340 patients who were either receiving cancer treatment or who had completed therapy.
Ginseng improves cancer patient's fatigue after 8 weeksThe study groups either received a placebo or 2,000mg of pure American ginseng root, which is an important note for women being treated for breast cancer.

Debra Barton, Ph.D., of the Mayo Clinic Cancer Center explained in a press release that ‘off the shelf’ ginseng is often processed with ethanol; giving it estrogen like properties that could pose dangers for breast cancer patients.
It took 8 weeks to see improvement in fatigue and symptoms of exhaustion, ‘feeling pooped’, ‘w…
