I have a couple of questions.
I learnt yesterday that animals don't have a problem with vitamin D, they process it through their fur. When we went furless we had to evolve so that we processed it through our skins. Does that mean that we have lost the ability to get vit D through our hair? I also read that bald men were more likely to experience severe coronavirus symptoms.
Also, one of my granddaughters has a couple of house cats, will they get enough vit D?
Cats and dogs can't adequately synthesis VitD through their skin so rely on diet for VitD. Indoor cats should be fine on a good diet.
I googled it yesterday and it came up with "Other mammals, including our own dogs and cats, synthesize vitamin D just fine because they activate it in their fur instead of their skin. We lost this option when we ditched the fur. Vitamin D deficiency is a uniquely human scourge."
And also "So in these cases, the creatures' skin secrete oils or waxes which coat and impregnate its fur or feathers. Sunlight then interacts with the oil and produces vitamin D, which is then ingested by the animal or bird when it grooms itself." Fancy that!
Depends what you read, my comment is from a veterinary point of view.
No, I think they are both true. If you take your dog for a walk then his fur will absorb lots of Vit D into the strands of hair which cover a much larger area then a patch of skin. Mind you they are not as good as cats at washing themselves so they need to get more of their vitamin D from their food. And most cats stay outside longer so maybe need to rely less on their food for it. My granddaughter is moving to a house with a garden in July which may be just as well. I've no idea what she feeds them with.
It's a bit like us. We get the vitamin from the sun and our food or a supplement. As I've hardly been outside I get mine from supplements.
If we all had brilliant diets with lots of oily fish we wouldn't need supplements.
This ad in the paper was what started me thinking about it.

I read that as we age and our skin becomes thinner it is harder to absorb the vitamin D. My partner who is 82 spends time outside with his fishing buddies and gets lots of sun but awhile back was tested through his clinic and was deficient in D. He took supplements for awhile to bring it up. So there was be something to the thin skin. Almost all older people are deficient. 😒
Yes, I know that's right and when I go out these days, very rarely, the only part of me the sun sees is my face and hands. And hair.
Still with my 75 mg of vit D a day (3000 iu) I am pretty sure I am not now deficient in it.
For years I took 12 mg in the tablets I got from Tesco's and thought I would be fine then found out that I was deficient. Without this forum I would still be deficient!
Yes. I live in Florida. "The land of sunshine" as they call it. Lol! I do wear capris and get some on my lower legs too. But I know it's not enough. Drs here are so reluctant to test for deficiencies. I'm going to see a new Dr soon and hoping he'll be better. See if I shouid take supplements.Also Florida has LOTS of mosquitoes so a good reason to cover the skin. I've read mosquitoes love female humans more than males. Don't know if it's true but I sure get swarmed by them when I go outside. Can't be because I'm sweet! 😂😝
Take care.
Even for a young person face and hands make very little. That is why women who cover for religious reasons and do not supplement are usually very deficient. Whole body exposure is the best - as nature intended. Even though having an old skin my vit D still goes up in the summer even though I take the same amount of supplement year round. Because I actively sunbathe. It's good for your blood pressure too regardless of season as UVA rays provoke nitric oxide formation . Even in winter I sunbathe at midday if there is no wind as the sun is strong enough here.
I would like to sunbathe as you do. But I don't joke about the mosquitoes. They are in Florida year round and they carry diseases. There was just an alert for people to be careful being outside as the mosquitoes are carrying Lyme disease and the kind that causes encephalitis. And I don't remember right now but some other disease. They are nasty things. Sometimes if there is a nice breeze I will go and lay on the deck with shorts on and sleeveless top. The breeze will keep the mosquitoes from flying. So I try. But I totally agree with what you're saying. It's just not all of us can sunbathe as you do. 😔Take care.
We have mosquitoes . We have a screen door on the French window in our bedroom to keep them out in summer. As we get down to - 10°C in the winter that kills a lot off. They only seem to come out at night. You are right about mosquitoes liking females more. It's always me that gets bitten not my husband!
Yes where I originally come from, Kansas, and other states, they seem to come out at night or at least are worse at night. And winter in other states kill them off til spring comes again. But Florida being warm all year round the mosquitoes are year round too. 😣. They are much smaller than the mosquitoes in other parts of the country. But they are more numerous here. Lots of lakes and swamps, canals, and other water sources for them to breed year round. Scientists are always working on a way to keep them from breeding and some mosquitoes that have been genetically modified somehow have just been released in another area of Florida that will hopefully kill them off. It's an experiment that I hope works. It's over my head but I'm hoping whatever it is works. For years the local government agencies in many states have had big trucks basically full of liquid insect killer. We called them fog trucks. They would roll out when the sun went down and spray out these chemicals like a fog to kill off as many mosquitoes as they could. Bad thing is the spray was bad for humans and animals. You would be told to stay indoors and bring your pets in. !!!! Some places quit doing that but some still do. So spraying poison isn't exactly an answer. And I call Florida the bug capital of the country. Sooo many species of bugs here. Huge cockroaches. I think every species there is, is in Florida. Yuck. But on the other side, there are beautiful flowers and birds. Any place we live I suppose has the good and the bad. It's funny though. Florida is called "The land of sunshine". What they don't say that when it turns really hot, which is starting, most people stay in their homes in the air conditioning. Only go out in the mornings or evenings when it might cool off some. The heat and humidity gets to be too oppressive. I imagine more people will be flocking to the beaches in the heat since our governor has lifted most of the covid guidelines. 🙄 What a mixed up world it has become. But do take care. Be safe and well.
Here in the Limousin we have a more humid heat than in the south of France. You cannot leave a book out in summer after 8pm - the pages start to wrinkle! With climate change it has become drier over the last 5 years compared to when we first moved here 20 years ago. We don't have a lot of pollution as the main "crop" here is beef raised naturally in the green fields. There are some apple orchards too but no arable crops.
Sounds beautiful though without all the pollution. Florida has a lot of agriculture. Vegetables and beef too. A lot exported and also raised for other areas of the country to consume. But the soil is so overused here and not really good for growing unless it is fertilized and of course chemical fertilizers. So much of what is grown here has no taste. Can't tell if you're eating a cucumber or strawberry. And the strawberries look so good. No taste though. But people eat them. It depends on which state you live in as to how long the growing season lasts and what grows well where. In Kansas we probably had 4 good months of growing for a garden and when I grew up there we always had a vegetable garden in the summer. I sure miss that. And our vegetables tasted so good. No chemical fertilizers. And we had a big strawberry patch and unlike Florida strawberries ours were so sweet and juicy. We'd have strawberry shortcake often. 😊 Such good memories. And dad had flower gardens to. Tulips and irises, daisies. And lilac bushes. Jonquils. Petunias. Beautiful.
Yes the weather seems to be changing everywhere. I think it's mostly just mother nature at work. The earth cycles. I read not long ago the earth is overdue for an ice age. Hard to believe. But that's what some scientists said. Who knows. The earth does what it will. We can't stop it. I do think man isn't helping. But that won't change when we have countries like China and India still spewing out pollution. It has to be every country. Not just a few. I think it may be a couple more centuries or more and man will be his own demise. Unless there is drastic change in the future.
I am making a pot of soup. It's called 15 bean soup. 15 different beans and I add my own seasonings. It comes with a seasoning packet but it's full of sodium and chemicals so I throw it out and use my own. Might be ready for lunch. 😁. I better go. I suspect there's a couple of people seething because we're off topic. 😱 So off to check my boiling beans and what to add. Oh today is Mother's day here. I don't know if other countries celebrate it or not. Whether you do or not, HAPPY Mother's day!
Take care.
Not sure when Mother's day is here in France. I should because my adopted daughter is only adopted here and not in the UK! She always keeps to the UK Mother's day which is in March. I use beans in stews with pork. They go well together and you can use less pork. They are nice with chorizo as well. Spices like cumin and ginger go well.
Sounds good. I use ham in my 15 beans. I get low sodium ham. Not fond of chorizo. I try to keep it as healthy as possible. 😊 Have a great rest of your day!
I'm on the south coast and we have gnats sometimes. Wildlife is limited to squirrels.
It is wearing too many clothes that leads to vit D deficiency! And hanging around inside . Not to mention smearing our skin with noxious chemicals. Africans living a traditional lifestyle wearing next to nothing have levels round about 45-50ng/mL. And they probably wear more today than they did before stupid missionaries got hold of them. People who work as beach swimming guards or at outdoor pools also have high levels . You are right about animals. I expect pet food has fortification.
Cats and dog produce vitimin d in their fur ...then lick it off... They can adequately synthesize it in their fur. Its not a very veterinarian perspective if you ignore basic biology.
Dogs get it by living their hair. If you lick your hair you'll probably get some vitimin d as well since the greasy substance if you let it flow will have some vitamin d and lots of other things too. But personally I don't have hair anywhere that I can reach to lick.
Actually I've just realised that apart from my elbows everywhere I can't reach is where the hair is... Maybe we licked our own fur away! Lol!
All your cats and dogs will get enough vitamin d if they consume it in their fortified tin's of " food" even if they are house cats. Cats and dogs who are washed very often have the oils washed away and so don't get it from their fur either...Most dog foods have vitimin d in the food.
You're a bit like Schrödinger's cat!
Maybe we should all take our clothes off outside 😉? I've really noticed the difference if it's sunny and I spend time outside. As for the coronovirus myth - if the bald man is overweight and over 50 maybe he will suffer more from the virus. There's an excellent British study called PERFORM that you can read or listen to where they talk a little bit about some risk factors. It's something to do with having more ACE2 receptors in the body due to overall size.
Yes, you are right. But were they looking at men with male pattern baldness as against those with a lot of hair?
I was wondering about the mechanism where the vitamin d, which they say is produced in an animal's fur, actually gets into the animal. It can't be just by grooming because most animals don't lick their fur. Maybe the oil rests on the skin and is absorbed that way. Maybe humans still get vit D through the hair they've got. It's just that they've got much less.
Vitamin D in the diet? Not many oily fish in the jungle and cows eat grass.
I haven't found any reliable information that dogs get Vit D through licking their fur. It's almost all through their diet. The recommended amount is between 500IU and a max of 3,000IU per kg of food. I checked my dog's food and it has 778IU/kg so that's good.
