Low Vitamin D levels are associated with increased dementia risk
Vitamin D deficiency has recently been linked to many non-skeletal conditions, including mental and cognitive health. In a new study published in the journal Neurology, researchers sought to determine whether insufficient vitamin D blood levels were associated with an elevated risk of all-cause dementia and Alzheimer’s disease.
The study included 1,658 normally healthy adults who participated in the US population-based Cardiovascular Health Study. Participants were free from dementia, cardiovascular disease and stroke at the beginning of this study. Previously collected serum vitamin D samples were analyzed and dementia and Alzheimer’s status were assessed during follow-up using criteria by the National Institute of Neurological and Communicative Disorders and Stroke/Alzheimer’s Disease and Related Disorders Association.
Over an average of 5.6 years of follow-up, 171 adults developed all-cause dementia, including 102 cases of Alzheimer’s disease specifically. Compared to subjects with vitamin D blood levels at or above 50 nmol/L (20 ng/ml), participants who were severely vitamin D deficient (<25 nmol/L, or 10 ng/ml) were more than twice as likely to develop all-cause dementia. Subjects with vitamin D levels considered deficient (25 to 50 nmol/L) were 53% more likely to develop all-cause dementia than the group with sufficient levels. Compared to those with sufficient vitamin D levels, subjects that were severely deficient and deficient were 122% and 69% more likely to develop Alzheimer’s disease, respectively.
The results add support to the idea that vitamin D plays important roles in non-skeletal conditions, and confirms that vitamin D deficiency (below 50 nmol/L or 20 ng/ml) is associated with a substantially elevated risk of all-cause dementia and Alzheimer’s disease.

Predictors of vitamin D status in adults residing in the United States
Vitamin D status in humans is influenced by numerous factors, including dietary intake, skin color, season of the year and geographic location. Typically, the most important factor related to vitamin D status is exposure to sunlight and UV conversion in the skin to active vitamin D in the body. However, because of recommendations by several health agencies to limit sun exposure, vitamin D status in adults and children have declined in recent years.
In a new study published online in the European Journal of Clinical Nutrition, researchers sought to identify predictors of vitamin D status in an adult population and determine the extent to which supplemental vitamin D and other factors influence vitamin D status.
The current study included 743 healthy adult volunteers from across the United States (including Hawaii and Alaska). Serum vitamin D was measured, and information on diet, supplement usage, ethnicity, age and body mass index (BMI), and latitude of residence was collected and used to analyze vitamin D status in a summer and winter group of subjects.
The most significant positive predictor of vitamin D status was supplementation, and the most significant negative predictor of vitamin D status was BMI. Fortified beverages in the summer and dairy intake in the winter also had a positive influence on vitamin D status. Other negative predictors were race (African American, Asian and Hispanic) in the summer; and residing above 36 degrees N latitude and ethnicity (Asian and Hispanic) in the winter. When considering the level of 50 nmol/L (20 ng/ml) to be adequate, of the non-supplement users 38% had inadequate levels in the winter and 18% were too low in the summer. In contrast, only 2.5% and 1.4% of supplement users had insufficient vitamin D levels in the winter and summer, respectively. Among supplement users, the average vitamin D supplement intake was 1967 IU/day in winter and 2282 IU/day in the summer.
In this population of adults, vitamin D supplementation was the most important predictor of vitamin D status in both winter and summer. This research indicates that a large percentage of healthy, free-living adults in the U.S. who do not consume a vitamin D supplement are at a significant risk for a suboptimal vitamin D status and its consequences. Vitamin D supplements are an effective and practical method of reducing hypovitaminosis D in U.S. adults.

Your Brain on Hope
I returned from the 2014 USANA International Convention in Salt Lake City to find this powerful article in our email today. It was so insightful and inspiring that I had to share it.
I googled Dana Wilde and added a link below in hopes that I can attribute it to the correct person. I hope you are touched by the message and encouraged enough to take action. Cheers!
Your Brain on Hope by Dana Wilde
Have you ever met that network marketer who is brand new to their business and just bursting with enthusiasm? The one who is SO filled with excitement that everything he or she touches seems to turn to gold? Do you ever remember feeling like that yourself?
I remember hearing the president of my direct sales company call it, “ignorance on fire.” We don’t know what we’re doing, but we’re doing it with such gusto that we meet with success after success.
The reason for this phenomenon actually has its roots in brain science. When your brain is in a positive emotional state, it’s more resourceful. You literally get better ideas.
In addition, when you are in a positive emotional state, the reticular activating system in your brain is filtering through all of the available information in the world around you and matching you up with the right people at the right time. You’re having better results because you are “tuned in” to all the best opportunities around you.
Most of us want to feel like that enthusiastic newbie. Sometimes we look at our businesses and wonder, “Where has my mojo gone and how can I get it back?” We end up feeling frustrated with our business because it’s growing too slow or maybe we feel stuck or like we’re spinning our wheels.
Well, if you’ve ever felt like this, then I have good news for you. You don’t have to be bouncing off of the walls with excitement to start to gain some traction in your business. All you really need is a little “hope.”
When you are in a frustrated, stressed, or overwhelmed state of mind, you are literally stifling the creative pathways in your brain. In order to open up your brain and get your mojo flowing again, you MUST shift yourself to a positive state of mind and the entryway to that shift is the feeling of HOPE.
Hope is enough.
When you put yourself into a feeling of “hope” – and remain there as consistently as possible – you can accomplish great things quickly and easily, even if you never make it to feelings of enthusiasm, passion, or joy.
Many entrepreneurs have mood swings between the emotions of frustration and hope. Typically, they have small successes quickly followed by small setbacks. The typical entrepreneur will focus on the small success and feel good and then they will focus on the small setback and feel bad. Ping-ponging back and forth between these two emotions, they never really gain any traction, which is why many businesses grow incrementally instead of by leaps and bounds.
This is why getting to a feeling of hope is so important. If you can get yourself to a feeling of hope-and stay there consistently-you create a resourceful brain that finds solutions for you.
You start to have small successes, and if you focus on those successes and ignore the setbacks, it becomes easier to stay in a feeling of hope. If you stay with hope long enough, then the successes pile up and it becomes easier to have feelings of belief, positive expectation, knowing, joy, and appreciation.
And it all starts with hope.
So if you’re feeling frustrated with your business, how can you start feeling more hopeful right now? You can start with what I call, The Hope Exercise.
The Hope Exercise is really simple. It’s designed to help you focus on statements that generate the feeling of hope. In other words, if you “think” hopeful thoughts long enough, you will automatically start to “feel” hopeful.
Here’s how it works:
Whenever you feel frustrated or overwhelmed, just pause, take a deep breath and start saying phrases or statements beginning with the words … “I hope.”
Your statements might sound something like this:
“I hope I start to feel better.”
“I hope I find a way to get my business moving.”
“I hope I find a method that makes my business easier.”
“I hope I get some people to buy my product.”
“I hope someone walks up to me out of the blue and buys something.”
“I hope I make a lot of money in this business.”
“I hope I attain my goals.”
“I hope I start to feel more positive.”
“I hope I my business grows this year.”
“I hope things improve.”
“I hope I can think of another hope sentence.”
When you’ve said your hope statements a few times, pay close attention to how you “feel.” If you find your emotions dipping back into frustration again, keep applying your hope statements. This will ward off counter-productive thinking right away. It will get you quickly back into that hopeful feeling again!
Keep saying your new “hope phrases” until you experience emotional movement towards genuine feelings of hope.
Another important note: When you first start using hope statements you’ll find, though you’re making hopeful or optimistic statements, they might sound and feel more like frustration than hope to you. However, if you say your statements for several minutes, you’ll begin to feel your emotions soften, your mood lighten, and you’ll quickly start feeling better.
Better thoughts translate into better feelings and better feelings translate into a more resourceful brain and a more successful business.
While many of us would like to feel like that enthusiastic newbie all day, every day, you’ll soon realize that your “brain on hope” is a powerful force for positive change in your business and in your life.
