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…

Coronavirus stimulus check 2: Get it together, Congress

By Michelle Jones. Originally published at ValueWalk.

Many Americans are waiting for coronavirus stimulus check number 2, and the June jobs report caused some to think there won’t be one. However, it sounds like a second round of IRS stimulus checks is still possible. In fact, we might even be able to say that it’s likely.

"Panic-Driven Hoarding Of Bank Notes": People Aren't Abandoning Cash During The Pandemic, They're Socking It Away

Courtesy of ZeroHedge View original post here.

Habits change in the midst of a global recession, not to mention a global pandemic. We have already looked at how the pandemic has caused seismic shifts in many industries, but it is also causing a shift in how people think about, handle and (in this case) hoard cash. 

While we have been told non-stop that the pandemic is going to prompt the demise of paper currency and the words "digital dollar" continue to make appearances in government white papers and studies, the Bank of England found that there was a...

Golds quick price move increases the odds of a correction

Courtesy of Read the Ticker

Every market corrects, maybe profit taking, maybe of allowing those who missed out, to get in!


The current open interest on the gold contract looks to high after a very fast price move, it looks like 2008 may be repeating. A quick flushing out of the weak hands open interest may take place before a real advance in price takes place. The correction may be on the back of a wider sell off of risk assets (either before of after US elections) as all assets suffer contagion selling (just like 2008).

This blog view is a gold price correction of 10% to 20% range is a buying opportunity. Of course we may see  a very minor price correction but a long time correction, a price or time is correction is expected, we shall watch and...

Wild Volatility Continues As US Markets Attempt To Establish New Trend

We’ve continued to attempt to warn investors of the risks ahead for the US and global markets by generating these research posts and by providing very clear data supporting our conclusions.  Throughout the entire months of May and June, we’ve seen various economic data points report very mixed results – and in some cases, surprise numbers as a result of the deep economic collapse related to the COVID-19 virus event.  This research post should help to clear things up going forward for most traders/investors.

As technical traders, we attempt to digest these economic data factors into technical and price analysis while determining where and what ...

The tech bubble didn’t end well. BUT it did tell us that the world was shifting into the technology age…

Since the Nasdaq 100 bottomed in 2002, the broader markets have turned over leadership to the technology sector.

This can be seen in today’s chart, highlighting the ratio of Nasdaq 100 to S&P 500 performance (on a “monthly” basis).

As you can see, the bars are in a rising bullish channel and have turned sharply higher since the 2018 stock market lows. This highlights the strength of the Nasdaq 100 and large-cap tech stocks.

The COVID 19 pandemic is, predictably, worsening again in much of the US. Only the Northeast, and to a lesser extent some Midwestern states, have been consistently improving. And that trend could also reverse as those states fully reopen.
