== User Zefr revoked new Myth section in Carrot article ==
Regarding page:<br/>
https://en.wikipedia.org/wiki/Carrot<br/>
Audit log shows user Zefr undid update citing "may be true but content & source are weak".<br/>
<br/>
Response from user Gedium:<br/>
1) "may be true" is incorrect as it is true. References below followed by reasoning followed by summary.<br/>
<br/>
1.1) https://en.wikipedia.org/wiki/Night_vision#Biological_night_vision<br/>
"The retinal must diffuse from the vision cell, out of the eye, and circulate via the blood to the liver where it is regenerated. In bright light conditions, most of the retinal is not in the photoreceptors, but is outside of the eye. It takes about 45 minutes of dark for all of the photoreceptor proteins to be recharged with active retinal, but most of the night vision adaptation occurs within the first five minutes in the dark. Adaptation results in maximum sensitivity to light. In dark conditions only the rod cells have enough sensitivity to respond and to trigger vision."<br/>
"Rhodopsin in the human rods is insensitive to the longer red wavelengths, so traditionally many people use red light to help preserve night vision. Red light only slowly depletes the rhodopsin stores in the rods, and instead is viewed by the red sensitive cone cells."<br/>
"Therefore, using red light to navigate would not desensitize the receptors used to detect star light."<br/>

1.2) https://en.wikipedia.org/wiki/Carotenoid<br/>
"Carotenoids that contain unsubstituted beta-ionone rings (including beta-carotene, alpha-carotene, beta-cryptoxanthin and gamma-carotene) have vitamin A activity (meaning that they can be converted to retinal), and these and other carotenoids can also act as antioxidants."<br/>

1.3) https://en.wikipedia.org/wiki/Rod_cell#Revert_to_the_resting_state<br/>
"Rods make use of three inhibitory mechanisms (negative feedback mechanisms) to allow a rapid revert to the resting state after a flash of light."<br/>
"The decrease in the concentration of calcium ions stimulates the calcium ion-sensitive proteins, which would then activate the guanylyl cyclase to replenish the cGMP, rapidly restoring its original concentration."<br/>

1.4) https://en.wikipedia.org/wiki/Rod_cell#Sensitivity<br/>
"A rod cell is sensitive enough to respond to a single photon of light[9] and is about 100 times more sensitive to a single photon than cones."<br/>

1.5) https://en.wikipedia.org/wiki/Retinal<br/>
"Retinal, also called retinaldehyde or vitamin A aldehyde, is one of the many forms of vitamin A (the number of which varies from species to species). Retinal is a polyene chromophore, bound to proteins called scotopsins and photopsins, and is the chemical basis of animal vision. Retinal allows certain microorganisms to convert light into metabolic energy."<br/>
"Retinylidene is the divalent group formed by removing the oxygen atom from retinal, and so opsins have been called retinylidene proteins."<br/>

1.6) https://en.wikipedia.org/wiki/Retinal#Vision<br/>
"Vision begins with the photoisomerization of retinal. When the 11-cis-retinal chromophore absorbs a photon it isomerizes from the 11-cis state to the all-trans state. The absorbance spectrum of the chromophore depends on its interactions with the opsin protein to which it is bound; different opsins produce different absorbance spectra."<br/>

1.7) https://en.wikipedia.org/wiki/Adaptation_(eye)<br/>
"Rods, whose photopigments regenerate more slowly, do not reach their maximum sensitivity for about half an hour."<br/>

1.8) https://en.wikipedia.org/wiki/Carrot#Nutrition<br/>
"The carrot gets its characteristic, bright orange colour from β-carotene, and lesser amounts of α-carotene, γ-carotene, lutein and zeaxanthin.[22] α- and β-carotenes are partly metabolized into vitamin A ..."<br/>

1.9) https://en.wikipedia.org/wiki/Photopigment<br/>
"Examples for photoreceptor pigments include retinal (for example in rhodopsin), ..."<br/>

1.10) https://en.wikipedia.org/wiki/Vitamin_C#Deficiency<br/>
"Men in the prison study developed the first signs of scurvy about 4 weeks after starting the vitamin C free diet, whereas in the British study, six to eight months were required, possibly due to the pre-loading of this group with a 70 mg/day supplement for six weeks before the scorbutic diet was fed.[44]"<br/>
<br/>
My analysis for a logical argument is that:<br/>
(re 1.8) Carrots contain beta-carotene, and less amounts of alpha-carotene which are partly metabolised into vitamin A.<br/>
(re 1.2) Carotenoids that contain beta-carotene, alpha-carotene can be converted to retinal.<br/>
(re 1.5) Vitamin A is metabolised into vitamin A aldehyde also known as Retinal. <br/>
(re 1.5) Retinal is a polyene chromophore, bound to proteins called scotopsins and photopsins, and is the chemical basis of animal vision.<br/>
(re 1.6) Vision begins with the photoisomerization of retinal.<br/>
(re 1.4) A rod cell is sensitive enough to respond to a single photon of light.<br/>
(re 1.1) Rhodopsin in the human rods is insensitive to the longer red wavelengths.<br/>
(re 1.3) Rods make use of three inhibitory mechanisms (negative feedback mechanisms) to allow a rapid revert to the resting state after a flash of light.<br/>
(re 1.1) It takes about 45 minutes of dark for all of the photoreceptor proteins to be recharged with active retinal.<br/>
(re 1.1) The retinal must diffuse from the vision cell, out of the eye, and circulate via the blood to the liver where it is regenerated.<br/>
(re 1.7) Rods, whose photopigments regenerate more slowly, take 30 minutes to reach maximum sensitivity.<br/>
(re 1.9) Examples for photoreceptor pigments include retinal (for example in rhodopsin).<br/>
<br/>
When people say something similar to "Eat your carrots as it helps you see better at night" this is incorrect as:<br/>
1) Carrots are only one source of beta-carotene, alpha-carotene. A healthy diet contains many other sources of beta-carotene, alpha-carotene.<br/>
2) The human eye rod minimum detection is 1 unit of photon.<br/>
3) The human body already has a limit on retinal quantity production.<br/>
4) Inhibitory mechanisms revert to a resting state.<br/>
5) Retinal is regenerated by the liver.<br/>
So the resting state is never increased as the human eye rod has already evolved to the maximum sensitivity of photons, thus carrots do not improve night vision sensitivity.<br/>
The only circumstance when carrots could help is when a diet is insufficient of beta-carotene, and alpha-carotene. Recalling that the human body has a buffer (i.e. blood plasma) where in the event the diet no longer provides required vitamins the buffer is used until depleted at which time organ failure commences. Vitamin C has about 2 weeks of buffer (source secondary, not recorded in Wikipedia.org, although when I locate the secondary source I will update Wikipedia.org), where when exhausted results in physical symptoms at about 4 weeks (re 1.10).<br/>
<br/>
2) Australian Geographic is a reputable publisher, however Outdoor Survival Bible (OSB) book lacks a reference section which does not make it ineligible, perhaps not a preferable source in user Zefr opinion. If OSB had a reference I would investigate the reference, and then do the same if the reference source referenced another source.<br/>
Question 2.1) Do all references have to be exhaustively verified to reach the original publication?<br/>
Question 2.2) Of the thousands of Wikipedia.org articles I have read many do not reference the initial source, so why has user Zefr required this to be mandatory?<br/>
Question 2.3) Encyclopedia is a tertiary source by definition which must reference sources. OSB is a secondary source and is permitted to be referenced.<br/>
<br/>
3) This update brings to other users attention that they can update the part and sources of the "Myth" section. Which currently had no entry although the Myth is extensively well known from my personal experience, so is appropriate to have an entry addressing it.<br/>

===The revert and subsection titles in question follow===
''Myth: See in the dark''
Gedium added:
"Sadly, while carrots are full of dietary fiber, antioxidants, and minerals, they don't actually help you see in the dark. This urban myth was put about by the Royal Air Force during the Second World War to explaining why they were enjoying such success during night air battles, and was actually used to disguise advances in radar technology and the use of red lights on instrument panels." Reference provided: |last=Beattie |first=Rob |title=[[Australian Geographic Outdoor Survival Bible]] |date=2011 |page=49

''Two points are disputed with the one reference Gedium used.'' 
::1) Carrots are not "full" of [[dietary fiber]] (only 2.8 g per 100 g consumed, see article table) and [[dietary minerals]] (all minerals analyzed are low in content, < 10% [[Daily Value]], see table). Science and regulatory guidelines for food labeling accept only vitamins A, C and E as dietary antioxidants. Carrots do not contain significant amounts of vitamins C and E, but the vitamin A value, as [[provitamin A]] [[beta-carotene]], is significant (104% vitamin A equivalent for the Daily Value, table). However, there is no evidence in the literature as [[WP:MEDRS]] that eating carrots = high vitamin A content contributing to eye health and improved night vision = myth about pilots eating carrots to improve night vision during WWII. The reference provided cannot be a [[WP:MEDRS]] source for carrot vitamin A and vision benefits. 
::2) The source provided, an outdoor guide not likely by its title to be specific about carrots, vitamin A, vision health or pilot dietary practices in WWII, is not verifiable, so fails [[WP:SECONDARY]] and [[WP:V]]. 
Finally, the discussion of this myth in the carrot article has low content value and seems to be Gedium's own interpretation, falling under [[WP:NOTESSAY]]. --[[User:Zefr|Zefr]] ([[User talk:Zefr|talk]]) 15:46, 5 September 2015 (UTC)

==Total vitamin A? 104% or 334% ?==
please see
http://nutritiondata.self.com/facts/vegetables-and-vegetable-products/2383/2

:Attempting to clarify: the Nutritiondata.com source (version SR-21; 2008 of the USDA National Nutrient Database) reports 16,705 IU of vitamin A per 100 g of raw carrots yielding 334% DV whereas the [https://ndb.nal.usda.gov/ndb/foods/show/2901?fgcd=&man=&lfacet=&count=&max=&sort=&qlookup=&offset=&format=Full&new=&measureby= most recent version SR-28 of the USDA database, here] reports 835 μg of vitamin A Retinol Activity Equivalents (RAE) per 100 g, converting to 104% DV. Vitamin A reporting readily leads to confusion because the relevant units may be presented as provitamin A beta-carotene (μg), vitamin A RAE (microgram, μg), or converted vitamin A (IU). Quoting from [http://lpi.oregonstate.edu/mic/vitamins/vitamin-A#RDA the Oregon State University source:] ''"provitamin A carotenoids like β-carotene are less easily digested and absorbed, and must be converted to retinol and other retinoids by the body after uptake into the small intestine. The efficiency of conversion of provitamin A carotenes into retinol is highly variable, depending on factors such as food matrix, food preparation, and one’s digestive and absorptive capacities."''
:In the United States and Canada, the [[Recommended Dietary Allowance]] is reported as vitamin A RAE, [http://lpi.oregonstate.edu/mic/vitamins/vitamin-A#RDA explained here as 900 μg RAE for adult males and 700 μg for adult females,] or an average of 800 μg for adults. In the Nutrition section and table, we have entered the 835 μg of RAE which the Wikipedia nutrition table converts to 104% DV per 100 g consumed (835/800 μg = 104%). --[[User:Zefr|Zefr]] ([[User talk:Zefr|talk]]) 17:02, 8 September 2016 (UTC)

== seed size ==

The article now contains a fancy image of highly magnified carrot seeds -- but the image contains no explicit or implicit scale information, obscuring the fundamental truth that carrot seeds are quite small. It would be good to have a similar image that includes a scale instead. Also an accompanying image of carrot seeds in the palm of a hand or some other similar image that conveys actual size in implicit natural way. -[[Special:Contributions/71.174.188.43|71.174.188.43]] ([[User talk:71.174.188.43|talk]]) 13:32, 21 March 2014 (UTC)

== Citation currently used for orange color origin explicitly says this is a legend ==

{{edit semi-protected|answered=yes}}
The article states:
* The western carrot emerged in the Netherlands in the 17th century,[52] its orange colour making it popular in those countries as an emblem of the House of Orange and the struggle for Dutch independence.[53] 
The citation, [53], points to http://books.google.com/books?id=KFQMt1Ww6osC&pg=PA81.

This citation explicitly refers to this as a "popular legend," and says that it was more likely that simple cooking preference led to the orange carrot being favored.

If a real citation of this legend can be found, then please use it. Otherwise the sentence should be edited to remove the second half, or by making it clear that this is unsubstantiated:
* The western carrot emerged in the Netherlands in the 17th century.[52] There is a popular belief that its orange colour making it popular in those countries as an emblem of the House of Orange and the struggle for Dutch independence, although there is little evidence for this.[53]

Currently the 'consumption' section contains said claim. It has 2 reference links. Both have in common that they lead to inaccessable books. At best such kind of references prove the claim insufficiently. If such a bold claim is raised, it has to be sufficiently supported by respective references, which give everyone direct access to information proving the claim. By this I'm not saying 'take out the claim', I'm saying that said claim in it's current form reduces the quality of the article and openly marking said weakness of the claim because of insufficient references is the least, which should be done.  <!-- Template:Unsigned IP --><small class="autosigned">—&nbsp;Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/178.201.144.69|178.201.144.69]] ([[User talk:178.201.144.69#top|talk]]) 17:57, 16 June 2018 (UTC)</small> <!--Autosigned by SineBot-->

== Not to 39%, by 39% ==

Carrots can be eaten in a variety of ways. Only 3 percent of the β-carotene in raw carrots is released during digestion: this can be improved to 39% by pulping, cooking and adding cooking oil.[55] 

This is wrong. 3% can be improved by 39% (increase to around 4%) NOT ''to'' 39%.  <!-- Template:Unsigned IP --><small class="autosigned">—&nbsp;Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/87.92.200.62|87.92.200.62]] ([[User talk:87.92.200.62#top|talk]]) 14:20, 26 May 2022 (UTC)</small> <!--Autosigned by SineBot-->

== Use of red lights on instrument panels ==

The [https://www.scientificamerican.com/article/fact-or-fiction-carrots-improve-your-vision/ article] referenced in the night vision section doesn't reference this at all, it only talks about advances in radar on the aircraft.

According to [https://forum.kerbalspaceprogram.com/index.php?/topic/82832-red-cockpit-lights/ this thread] the use of red lights supposedly gave the pilots better night vision as the photoreceptor rods in the eye are least affected by the longer wavelength (and hence lower energy) of red light. I haven't found a more reliable source about its use in WW2 aircraft, however it's not commonly used in aviation any more since as it makes it harder to read the readings on the instrument panels and interferes with night vision technology.

New to wiki editing so I'm not sure what to do here. I think it's ''plausible'' that the RAF believed this was giving them an advantage that they might want to obscure at the time, but the current reference doesn't support this. Open to more experienced opinions, but I think the red light reference should be removed or a stronger source should be found.

:Your analysis of the topic and sources was correct, and there is no good source to support the red panel lights having anything to do with beta-carotene from carrots and night vision.

Carrots can be stored for several months in the refrigerator or over winter in a moist, cool place. For long term storage, unwashed carrots can be placed in a bucket between layers of sand, a 50/50 mix of sand and wood shavings, or in soil. A temperature range of {{convert|32|to|40|F|C|order=flip}} and 98% humidity is best.<ref>{{cite web |url=http://www.backwoodshome.com/articles2/gist82.html |title=Successful Cold Storage |author=Gist, Sylvia |work=Backwoods Home Magazine |access-date=2013-03-21 |archive-url=https://web.archive.org/web/20110906104024/http://www.backwoodshome.com/articles2/gist82.html |archive-date=6 September 2011 |url-status=dead }}</ref><ref>{{cite web |url=http://www.plantea.com/carrots.htm |title=What's Up Doc?

== USDA nutritional data: "Carrots, mature, raw" (Foundation) vs "Carrots, raw" (SR Legacy) ==

This article uses the "Carrots, raw" from the "SR Legacy" USDA database ([https://fdc.nal.usda.gov/fdc-app.html#/food-details/170393/nutrients]). Since 2022, "Carrots, mature, raw" is available in the USDA "Foundation" database ([https://fdc.nal.usda.gov/fdc-app.html#/food-details/2258586/nutrients]). Should that be used instead? --[[User:Trougnouf|Trougnouf]] ([[User talk:Trougnouf|talk]]) 13:33, 13 December 2023 (UTC)

== Association with rabbits ==

I'm surprised this article doesn't mention the stereotypical association of carrots with rabbits. Can you add it in and find sources regarding this? [[Special:Contributions/128.235.13.36|128.235.13.36]] ([[User talk:128.235.13.36|talk]]) 15:44, 25 January 2024 (UTC)

== GA concerns ==

I am concerned that this article no longer meets the [[WP:GA?|good article criteria]]. Some of my concerns are listed below:

*There are uncited passages throughout the article, including the entire nutrition and most of the etymology sections. 
*The lead is quite short and does not mention all major aspects of the article. 

Is anyone interested in bring this article back to GA standars, or should the article go to [[WP:GAR]]? [[User:Z1720|Z1720]] ([[User talk:Z1720|talk]]) 21:51, 2 September 2024 (UTC)

:The nutrition section is cited to the nutrition table, which derives from the [https://fdc.nal.usda.gov/fdc-app.html#/food-details/170393/nutrients USDA FoodData Central entry for raw carrots.] [[User:Zefr|Zefr]] ([[User talk:Zefr|talk]]) 22:21, 2 September 2024 (UTC)
::{{re|Zefr}} The prose should also be cited to the USDA FoodData Central entry in case the reader cannot see the table. There is also other uncited sections in the article. Are you interested in fixing these up? [[User:Z1720|Z1720]] ([[User talk:Z1720|talk]]) 20:36, 9 September 2024 (UTC)
:::I don't know what conditions would exist where a reader could not see the nutrition table. The USDA FoodData Central table of nutrient contents would not be instructive for most users, as it does not convert data into familiar food label terms, like the [[Daily Value]] (DV) presented in the section (then calculated by the ''nutritionalvalue'' template). This has been discussed previously for other food nutrition sections, and having a summary of significant DVs in the prose, with the nutrition table referenced for more detailed review, seems to be clearest for covering nutritional content.
