Vitamin d deficiency.

Very good advice brassneck.....

This is probably the first time you've posted something worth reading Brass. Well done.

I take Vitamin D every day.....felt a lot better after I started taking it.

I also take a Multivitamin every day (was getting leg cramps....seems the cure is Magnesium)

Beware..... tried Waitrose own label but semi-liquified my lower bowel tract....now using Seven Seas.

NB : If you are in the Sun in a car..... you are not getting hardly any Vit D boost as the glass cuts out 95% of the beneficial light.

Mushrooms exposed to the sun can provide as much vitamin D as a health supplement, a study has found. Researchers recommend people take the fungi out of their wrapping and leave them outside for half an hour before eating.

Is that assuming clear sunlight, or the soupy half light, of an English day?

They don't like UV so make vit D to protect themselves. I think we have plenty of UV on cloudy days so it should work here. It's popular in the mountains in Hungary to slice and dry them in the sun to give them vit D through the winter. I'm guessing they were doing this long before anyone gave a name to vitamins.

And that's why mother nature is a racist, white supremacist beach.

People with dark skins, need far more exposure to sunlight in comparison to those with light skins to absorb their Vit D.

And if you take Vit D supplements, take one that includes K2 which helps to absorb the D.

It's all a load of bullshine anyway.

Always walk on the sunny side of the street.

Chemtrails give people with dark skins a Vitamin d deficiency.

Where do animals get their vitamins? They only eat grass.

And as far as Vit D is concerned, animals haven't got any exposed skin in which to absorb the sunlight.
Take a bear for instance, or a dog or a cat.
And many chickens we eat never see the light of day. And if they did they're covered in feathers.
Yet we're supposed to eat meat for its Vit D.

Seafood is supposed to be the richest source of Vit D.  So where do they get it from when they're under water all the time? 

Like I said - it's all bullshine designed to sell supliments.

I think animals make their own Crippen  ... 

  Winter sun is no good  ,it has no vit D benefits ...you should get  out in the daylight for an hour a day  exposing the skin  APRIL - SEPTEMBER  in the Southern UK  ...MAY to AUGUST in Scotland  ...you shouldn't need supps at all . 

your shadow  needs to be shorter than you as a rule of finger   ...appx 45 degree sun angle

''Most people can make enough vitamin D from being out in the sun daily for short periods with their forearms, hands or lower legs uncovered and without sunscreen from March to October, especially from 11am to 3pm.
A short period of time in the sun means just a few minutes – about 10 to 15 minutes is enough for most lighter-skinned people – and is less than the time it takes you to start going red or burn. Exposing yourself for longer is unlikely to provide any additional benefits.''

Someone I know who has suffered skin cancers, gets no sun exposure at all. He's always covered from head to toe.
Under the wide brimmed hat he always wears, his skin is so pale he looks like death.

Worked outdoors all his life.
Also diabetic which makes matters worse.

Dogs and cats form vitamin D in their coats by lying in the sun, then ingest it when they lick themselves. Same with anything with fur or feathers.

In humans ultraviolet light reacts with the oils in our skin to form vit D. The vit D then gets reabsorbed through the skin into the bloodstream. In animals the oils get into the coat, but the vit D gets trapped there, which is why they need to lick it off instead.

Interesting screaming.

But not according to this:

I'm not sure the author of that link has understood the study she quotes. It's entitled "Ineffective Vitamin D Synthesis in Cats Is Reversed by an Inhibitor of 7-Dehydrocholestrol-Δ7-Reductase".

https://academic.oup.com/jn/article/129/4/903/4721868

The authors of the study fed several groups of kittens an identically deficient diet and found they all suffered identical vitamin D deficiency, regardless of exposure to sunshine. But when they added an inhibitor of 7-dehydrocholestrol-Δ7-reductase to the diet of some of the kittens, this group showed a 5-fold increase in 7-dehydrocholesterol in their skin. (7-dehydrocholesterol is the oil which forms the precursor to vitamin D in human skin.)

So, with a more varied diet, cats evidently were capable of forming their own vitamin D via their skins and coats. However, the study seems to go on to show that with a more varied diet the cats would obtain enough vitamin D from their food in any case, making sunlight unnecessary, so they don't actually make any use of this vitamin D from the sun.

That's my reading of it, but I'm happy to be corrected.

Just to confuse the issue further, in 2012, thirteen years after that study, another author, from the College of Veterinary Medicine at the University of Illinois, stated:

“A lot is known about how humans, rodents, horses, cattle, pigs and sheep are able to synthesize vitamin D in their skin after exposure to the sun’s ultraviolet light,” says Dr. O’Brien. In fact, vitamin D got its original nickname—“the sunshine cure” —from the marked improvement tuberculosis patients made when they spent more time in the sun.

But Dr. O’Brien found that when she compared the vitamin D values from blood samples of healthy pet dogs and those of healthy dogs who spent all of their time indoors without exposure to sunlight, there was not a difference. And, studies show that cats also do not have the ability to produce adequate amounts of vitamin D in their skin.

“That is one of the aspects of veterinary medicine that makes it so challenging,” says Dr. O’Brien. “Although we know of a vast number of similarities across species, it is never a good idea to assume that any physiological trait is the same without testing to make sure.”

Does this mean that vitamin D isn’t as important for dogs and cats as it is for humans? Not at all.

“In the past 25 years, we’ve learned that nearly every type of cell in the vertebrate body contains receptors for vitamin D, not just the cells associated with skeletal health,” notes Dr. O’Brien.


I suppose the conclusion is that dogs and cats are capable of making vitamin D from sunshine, but not to any adequate extent.

I think.

The funny thing is that while Western diets are richer now than they've ever been, our health is as bad as it's ever been.
With heart disease, diabetes, cancer, arthritis, chronic fatigue and asthma, so common that it's almost expected for people to suffer something.

So much for nutrition.

look at various foodstuffs in the shop Crippen  - either over sweetened or oversalted , over processed or over sweetened with various  chemicals    ... yet everything else is tasteless fat free food and i'm not even convinced full fat is bad  ...i think it's good in moderation 

also , the air outside is putrid ...all you can smell and taste in towns is the stench of diesel  ... 

after saying that ,we live longer  albeit because of artificial means and therefore arte going to get more ill folk  ....plus old heavy smokers are still around but some in poor health .

another thing ...most packaged food is bulked out with flour ...it's hard work trying to find food on the go with any fresh imgdredients  unless u pay an arm and a leg
