Default Mushrooms, Vitamin D and More Food Facts

I didn't know this ...

Quote:
Mushrooms make vitamin D in sunlight.

Most people are aware that the human body makes vitamin D in response to sunlight. Less known is the fact that mushrooms, even picked ones, can perform the same feat - which means that eating mushrooms that have been exposed to sunlight can be an excellent way to supplement your "D" levels.

In the summer of 2004, mycologist Paul Stamets discovered that the level of vitamin D in freshly picked, indoor- grown shiitake mushrooms rose from 110 IU (international units) to an astonishing 46,000 IU per 100 grams when the mushrooms were placed outdoors in the sun for just six hours with the gills facing up (when the gills were facing down, the level rose to 10,900 IU).

This means that eating just one gram of sun-treated shiitake - about one tenth of one mushroom - would give you 460 IU, close to the FDA's recommended daily dose of 400 IU, and about half of Dr. Weil's recommended 1,000 IU.

In his book, Mycelium Running: How Mushrooms Can Help Save the World, Stamets concluded, "(In) populations where vitamin D is seriously deficient, sun-exposed dried mushrooms can help address a serious health issue."

wow, that is really interesting. wonder what the gills do.. when you think about it, the gills face downward in a normally growing mushroom.. so normally they wouldn't get sunlight, right? It is interesting that they would absorb so much?

but, what a delicious way to get your vitamin D.

Received 27 September 2004; revised 6 December 2005; accepted 17 January 2006. Available online 17 March 2006.


Abstract

Kinetics of conversion of ergosterol to vitamin D2 has been investigated in cultivated edible mushrooms. It was observed that the rates of conversion of ergosterol to vitamin D2 were varied in different types of mushrooms. Oyster mushrooms (Pleurotus ostreatus) showed the highest conversion rate followed by Shiitake (Lentinula edodes) and Abalone (Pleurotus cystidus) whereas the lowest conversion rate was observed in Button mushrooms (Agaricus bisporus). Both initial moisture content and temperature of irradiation influenced the conversion of ergosterol, and a 2 � 2 factorial design was used to study this influence. It was shown that the conversion of ergosterol to vitamin D2 followed zero-order kinetics, where the rate constant varied with temperature according to the Arrhenius equation (K0 = 7.32 s−1; Ea = 51.5 kJ mol−1). Vitamin D2 yields from Shiitake mushrooms with respect to temperature of irradiation (T) and moisture content of the mushrooms (M) can be calculated from the equation:


D2=-91.3+2.25*T+71*M.
the equations says that the more moisture (M), the more D2. Also, the higher the temperature of irradiation (T), the more D2 created. However, I can't tell from this study what the range of temperature and moisture was..

but still, I guess the more moisture content of the mushroom, the more D2 that can be created for a set temperature.

I wonder if this might be a clue that the earth emits some miniscule amount of UV rays?

don't know.. maybe MadScientist would.

I know the earth emits infrared (heat) radiation. I'm no help, am I?

Mushrooms in general seem to be a "superfood". power food.

so.. I am going to post my "secret" recipe for mushroom spaghetti sauce.

ingredients:
  • first.. go to the grocery store and buy plenty of mushrooms. at least a lb.
  • tomato paste - a couple of cans. I buy organic tomato paste.. besides knowing that it isn't gmo.. it tastes MUCH better. really. a big difference. not so for everything, but tomato paste.. yes.
  • tomato sauce.. one 8 oz can. you will mainly use the paste.. but some people to add some sauce anyway.
  • also, garlic, (or garlic powder).
  • Italian seasoning (easy, and you can use it in so many things),
  • fennel (optional).
  • red wine (optional)
  • I use ground turkey, but, ground meat (or no meat) would be fine.
  • olive oil (hey, this is italian.. you must use olive oil)
instructions:
  1. wash mushrooms. then slice. rinse again to make sure they are clean.
  2. cook ground meat (if you are using it), drain, and put aside.
  3. heat the pan, put a little oil oil in.. heat, then put in the sliced mushrooms and sprinkle with salt. toss them around a bit, then cover the pan. You want to keep the liquid.. and there will be some liquid. The heat and salt reduces the mushrooms and produces a lot of "mushroom liquid"
  4. when mushrooms are cooked (and smell good), add tomato PASTE. the tomato paste will blend with the mushroom liquid to make sauce. if you need to.. add another can of tomato paste. you can add the sauce if you want more of a tomato type sauce. Depends on how many mushrooms and how thick you like your sauce. this is an individual thing.
  5. crush a couple of cloves of garlic and add (or add garlic powder)
  6. add a tbsp. Italian seasoning.
  7. optional: add a dash of wine
  8. optional: add a tsp of fennel ... you will get a bit of an italian sausage taste with this. probably better to skip this the first time you make it.
  9. add ground meat if you cooked it (in step 2)
  10. cover and simmer at low for at least 20 minutes. longer if you have time.
you will have a sauce with a LOT of mushrooms.. and the sauce will have a bit of a more mushroom flavor because of the tomato paste and mushroom liquid.

this is good with pasta.. but you don't have to serve this with pasta.. you can serve it over plain chicken breasts. with some mozarella

my husband likes it with cottage cheese. (strange, I know.. but I tried it, and it is pretty good).

and .. a good healthy combo. tomatoes, mushrooms, garlic, oregano, olive oil, mineral salt (if you use mineral salt). what's not to like?

I like your recipes, Scorpiotiger. I don't know what "Italian seasoning" is, so can you give me a breakdown of the ingredients? Is it something you buy as a branded product? I'm sure I can put it together, once I know what's in it.
We have about a gallon of olive oil, but I must whisper this quietly - it's Greek! I pefer the Iliada brand for taste and quality.

I have a similar recipe but when I cook the mushrooms I sautee them in butter and soy sauce. I cook them until they are browned, almost a little cripsy - golden.

then I take the shrooms out and reconstitue the dripping in the pan that have almost dried up and add it to the sauce.

And yes! Fennel is the best secret ingredient to a sauce! I use it all the time.

My question is do the mushrooms, the common ones you purchase in the supper market have any significant medicinal value as the reshi and shitake do?

I don't think necessarily the Earth might emit UV, but possibly reflect it.

If you think about it, a lot of UV for example is reflected by Windows, to my understanding, although a lot can get through, depnding on the kind of furnishings you have adorning your window.

The ground could also possibly do this, or maybe the soil has a UV saturation point, like a sponge, whereby the UV is dealt with by organisms, until UV in soil is lowered enough, to take more UV.

I kind of like the thought, that UV could be reflected onto the underside of edible Fungi like that, creating the effect of increased nutrient levels, via said method.

Were this possible, the amount of reflection or any, could also theoretically depend on the type of soil, I.E. Clay, Loamy, Peaty etc etc.

I've had people say.. this is really good.. but what is it that is in it? I like it.. but I can't identify it. Then I will say.. like italian sausage? they will say, Yes!! but what is it? Then they are really surprised when I tell them.

but.. a little fennel goes a long way, imo.

another ingredient that you would not expect.. nutmeg in creamed spinach. goood.

well, I found this on PubMed:
https://www.ncbi.nlm.nih.gov/pubmed/18287364
Quote:
White button mushroom enhances maturation of bone marrow-derived dendritic cells and their antigen presenting function in mice.

Ren Z, Guo Z, Meydani SN, Wu D.
Nutritional Immunology Laboratory, Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University, Boston, MA 02111, USA.


Mushrooms have been shown to enhance immune response, which contributes to their antitumor property.



White button mushrooms (Agaricus bisporus) (WBM) constitute 90% of the total mushrooms consumed in the United States; however, the health benefit of this strain in general is not well studied. Furthermore, little is known about WBM's immunologic effects. Dendritic cells (DC) are the most potent antigen presenting cells and play a pivotal role in immune response by linking innate and adaptive immune responses.



In this study, we investigated the effect of in vitro supplementation with WBM on maturation of bone marrow-derived DC (BMDC) of C57BL mice. BMDC were differentiated in the presence of whole mushroom concentrate at 50, 100, or 200 mg/L.



Results showed that mushroom supplementation dose dependently increased the expression of maturation markers CD40, CD80, CD86, and major histocompatibility complex-II. Consistent with the changes in the phenotypic markers, functional assay for DC maturation showed that mushroom supplementation decreased DC endocytosis and increased intracellular interleukin (IL)-12 levels.



Furthermore, using a syngeneic T cell activation model, we found that WBM-supplemented DC from BALB/c mice presented ovalbumin antigen to T cells from DO11.10 mice more efficiently as demonstrated by increased T cell proliferation and IL-2 production.



In conclusion, WBM promote DC maturation and enhance their antigen-presenting function. This effect may have potential in enhancing both innate and T cell-mediated immunity leading to a more efficient surveillance and defense mechanism against microbial invasion and tumor development.
so.. it sounds like they are good for the immune system.

interesting.. I found this:
UV SOLAR RADIATION � a basic review
Quote:
Ground reflection
Part of the UV radiation that reaches the ground is absorbed by the Earth�s surface and part of it is reflected back to space. The amount of reflected radiation depends on the properties of the surface. Most natural surfaces such as grass, soil and water reflect less than about 10% of the incident UV radiation. Fresh snow, on the other hand, may reflect up to about 80% of the incident UV radiation. During spring and with a cloud-free sky the reflection of snow may increase the UV irradiance on inclined surfaces to summer values. This is important at higher altitudes and at higher latitudes. Sand may reflect about 25% of the UV radiation and can increase the UV exposure at the beach. Up to 95% of the UV radiation penetrates into the water and up to 50% penetrates to a depth of about 3 m (in clear ocean water).

I don't see how why mushrooms would be designed to catch reflected UV rather than direct rays. The normally only grow in dark or shady areas. If the gills were designed to catch UV, they would be on top.

Maybe direct rays are too strong and the cap is UV resistant, but the gills are to absorb the very weak reflected UV.

Hey ST thanks. I won't be having mushroom racist thoughts in the grocery store anymore. Those little guys will no longer be subject to my mushroom bigotry as they are moving to the forefront of equality
