The Vitamin-D Debate: How Much is OK?

The Vitamin-D Debate: How Much is OK?

Spend a few minutes soaking up some rays and your body will start to pump out more vitamin D. Many health officials believe Americans are D-deficient, but in the age of sunblock and self-tanners, how many vitamin-D pills should we be popping? New guidelines for the optimal dietary dose are expected in the fall, and definitive studies on vitamin D’s effects on cancer, heart disease and cognition are ongoing. In the meantime, here’s where the science stands.

Cancer
Vitamin D may prevent cancer by suppressing the cell growth and blood-vessel formation that feed tumors. At least that’s the idea, based on animal studies and analyses of human cells. But trials in which patients take vitamin D have not shown a consistent lowering of cancer risk.

One four-year trial of 1,200 postmenopausal women found a 77% lower risk of all cancers among those taking calcium and 1,000 IU of vitamin D a day than among those taking a placebo. A larger study, however, in which subjects took 400 IU of vitamin D — in the absence of an official daily recommended intake, that’s the "adequate" intake for adults ages 51 to 70 — did not show lower breast-cancer risk.

The data are strongest for colorectal cancer: subjects with higher blood levels of vitamin D were half as likely as those with lower levels to develop the disease. 

Heart Disease
Studies on animals and human-cell cultures indicate that vitamin D has a protective effect on the heart, controlling the release of stress hormones that lead to high blood pressure and inflammation.

Studies on human subjects confirm this link. In one trial, men whose blood work showed D levels below 30 nanograms per milliliter — the amount the Institute of Medicine says adults should aim for — were twice as likely to have a heart…

Turning Sunshine into Performance?

Turning Sunshine into Performance

vitamin d exposure By Ilene

Does vitamin D have anything to do with investing and stock and options trading? Maybe. Preliminary research suggests that lack of vitamin D is associated with impaired mental abilities. And this may indicate that obtaining sufficient levels of vitamin D may improve cognitive performance

Researchers stopped short of advising more sunshine, or fruit-flavored gummy D supplements (yum!), to improve one’s cognitive function. But further research is warranted.

In addition, and perhaps most importantly, many children appear to be deficient in vitamin D (see below) so it may be worth investing in some of those gummy Ds. 

Does Vitamin D Improve Brain Function?
New studies show low vitamin D levels may impair cognitive function

By Diane Welland, in Scientific American  

The push to prevent skin cancer may have come with unintended consequences—impaired brain function because of a deficiency of vitamin D…

“We know there are receptors for vitamin D throughout the central nervous system and in the hippocampus,” said Robert J. Przybelski,… “We also know vitamin D activates and deactivates enzymes in the brain and the cerebrospinal fluid that are involved in neurotransmitter synthesis and nerve growth.” In addition, animal and laboratory studies suggest vitamin D protects neurons and reduces inflammation.

Two new European studies looking at vitamin D and cognitive function have taken us one step further…

The scientists found that the lower the subjects’ vitamin D levels, the more negatively impacted was their perform­ance on a battery of mental tests…

A second study, led by scientists at the University of Manchester in England… looked at vitamin D levels and cognitive performance in more than 3,100 men aged 40 to 79 in eight different countries across Europe. The data show that those people with lower vitamin D levels exhibited slower information-processing speed…

Although we now know that low levels of vitamin D are associated with cognitive impairment, we do not know if high or optimum levels will lessen cognitive losses. It is also unclear if giving vitamin D to those who lack it will help them regain some of these high-level functions…

Do you remember this commercial?

The Etrade commercial aired during Super Bowl XLI in 2007. The following year, the financial crisis set in, markets plunged, and investors lost 50%, or more, of their wealth.

However, this wasn’t the first time it happened.

The same thing happened in late 1999. This commercial was aired 2-months shy of the beginning of the “Dot.com” bust as investors ...

Is Crude Oil Sending a Bearish Message to the Stock Market?

Courtesy of Chris Kimble.

Crude Oil (NYSEARCA: USO) and the S&P 500 Index (INDEXSP: .INX) have peaked and bottomed together several times in the past 9 months. See points (1) and (2) on the chart above.

In summary, the correlation between Oil and the stock market has been quite interesting and demands investors attention.

Crude Oil has been creating lower highs of late and is breaking price support at (3).

If the correlation remains the same, Crude Oil may very well be sending a bearish message to stocks.

Tricky spot for active investors – careful here.

Despacito - How to Make Money the Old-Fashioned Way - SLOWLY!

Are you ready to retire?  

For most people, the purpose of investing is to build up enough wealth to allow you to retire.  In general, that's usually enough money to reliably generate a year's worth of your average income, each year into your retirement so that that, plus you Social Security, should be enough to pay your bills without having to draw down on your principle.

Unfortunately, as the last decade has shown us, we can't count on bonds to pay us more than 3% and the average return from the stock market over the past 20 years has been erratic - to say the least - with 4 negative years (2000, 2001, 2002 and 2008) and 14 positives, though mostly in the 10% range on the positives.  A string of losses like we had from 2000-02 could easily wipe out a decades worth of gains.

Still, the stock market has been better over the last 10 (7%) an...

A good start from :

It's Not Capitalism, it's Crony Capitalism

Excerpt:

The threat to America is this: we have abandoned our core philosophy. Our first principle of this nation as a meritocracy, a free-market economy, where competition drives economic decision-making. In its place, we have allowed a malignancy to fester, a virulent pus-filled bastardized form of economics so corrosive in nature, so dangerously pestilent, that it presents an extinction-level threat to America – both the actual nation and the “idea” of America.

This all-encompassing mutant corruption saps men’s souls, crushes opportunities, and destroys economic mobility. Its a Smash & Grab system of ill-gotten re...
