Talk:Grapefruit

message: I am surprised that there is still not a section that mentions that the grapefruit tastes terrible. Is it not a bit irresponsible to forget that? Otherwise someone might read this article, buy a grapefruit, and have a pretty bad afternoon.  —Preceding unsigned comment added by 171.64.181.142 (talk) 23:13, 11 March 2008 (UTC)

text: Yes, obviously bitter. Have you never tasted it? I can't think of anything else that so well-defines the concept of 'bitterness'. Bienfuxia (talk) 07:50, 3 December 2010 (UTC)

text: I have to agree with Cjsunbird here. I would never have thought of grapefruit as being bitter, but rather as being sour. Things that "define the concept of bitterness" to me are dark chocolate and very green vegetables (e.g. kale). Bitter and sour are often confused, but I've been unable to find an authoritative source that clearly explains the distinction.91.106.92.86 (talk) 15:50, 29 January 2011 (UTC)
replies: text: if you think about the difference between the taste of a lemon and the taste of a grapefruit, the distinction should be clear. Grapefruit IS sour, yes, but it is also bitter - unlike other citrus fruits. Bienfuxia (talk) 02:15, 16 February 2011 (UTC)
replies: text: I have to admit I outright came to this talk page because I was confused about the prominent use of the adjective 'sour' in the article, expecting it to be some larger point of contention. I'd also definitely say it tastes bitter, as per Bienfuxia. (For the record, I really like grapefruit.) I find the taste comparable to Bitter Lemon (the drink), which definitely has a strong bitter component (unlike lemon juice). What kind of source could we look for that might clear up the terminology here? Would 'sour and bitter' work better? I was honestly confused that I didn't find it in the lede paragraph. -pinkgothic (talk) 14:04, 28 December 2011 (UTC)

Something like http://www.gfex.com/index2.html

It's practical usage is a quite valuable information.

message: Can somebody review the info about drug interactions with grapefruit juice. Drug Interactions with Grapefruit Juice: An Evidence-Based Overview is a valuable reference.
- I've never commented in a discussion, so I apologize if I'm out of place. The CYP3A4 inhibitor effects look correct. It's also an inhibitor (although to a lesser extent, I believe) of CYPs 1A2, 2A6, 2C9, 2C19, 2D6, 2E1. Reference here: 
All operate in drug metabolization to some degree. 2D6 is particularly important.
There's been recent press releases about furanocoumarin being the cause of the increased drug absorption which seems to conflict with the information in this article. This info needs to be corrected. 148.87.1.171
Lots of drugs are metabolised by CYP3A4: I've added a few more that are known. The issue is complicated by the fact that grapefruit juice appears to inhbit primarily intestinal CYP3A4 and not hepatic (liver) CYP3A4. Jed 20:50, 14 November 2006 (UTC)

message: I have deleted much of the text in medicinal uses, not because I disagree with it, but because it is poorly arranged and redundant.  This is hashed out in Grapefruit seed extract and does not need to fill up an article about the fruit.   It is enough to note that GSE is not the antimicrobial product it is claimed to be. -- WormRunner 04:11, 3 September 2006 (UTC)
thread_title:  Grapefruit seed extract 

message: I think grapefruit is "Citrus maxima". Citrus paradisi is the latin name of Pomelo. Or maybe it's a french inversion. What we call Pomelo is a sugar fruit and what we call "Pamplemousse" is a more bitter fruit. It seems that in english, Pomelo is the one which is more bitter and grapefruit more sweet. Can anyone confirm ? ThxAbrahami 17:01, 9 October 2006 (UTC)

message: Uh, where did this assertion come from? –BozoTheScary 18:15, 19 October 2006 (UTC)
replies: text: Yep, they all either reference Hughes or one of his followers-on or just say "was called 'forbidden'" without saying by whom or when.  Again, support for Hughes being the one to first name it that, a name that was promptly culturally ignored, but nothing about any groups at any time calling it 'forbidden' nor anyone asserting that it was ever considered poisonous, like the original "Lore" section asserted.  If anything, it appears to be too new of a hybrid to have been around long enough for anyone to have called it anything much before Hughes got around to it, much less long enough for there to have been anything even remotely describable as 'lore'. –BozoTheScary 00:55, 20 October 2006 (UTC)

thread_title:  Merging Grapefruit Juice 

message: I don't have any specific sources for it, but it would seem to me that the red (or pink) grapefruits have greatly increased in popularity and prominence over, say, the last twenty years.  In fact, at least here in the U.S., it's very difficult to find proper white grapefruit anymore in many places.  This seems like something that might fit in well under the "History"... JoAnneThrax 15:05, 21 December 2006 (UTC)

thread_title:  Colors and popularity 

message: It seems like we have three articles on the same fundamental point - grapefruit juice acts on certain CYP enzymes.
I propose that we eliminate "grapefruit juice" and "list of drugs affected by grapefruit" entirely (redirect to grapefruit), since they revolve entirely around the CYP inhibition effect.  Instead of those pages, we can have a brief note in the main grapefruit article about the CYP interactions.  That way a reader can follow the link to CYP3A4 or whatever if they want specific information about that.
This way, people who want to know about grapefruits can get relevant information in the article.  The article is about grapefruits, not about enzyme/drug interactions - a mere note that it will occur, a brief warning for consumers, and a link to the appropriate articles should suffice.  CYP3A4 adequately covers the information expressed in grapefruit juice/list of drugs affected, and does so under a more appropriate title.
Any thoughts, suggestions?  My primary concern is that we have multiple articles with the same information, and that we could condense this information and put it into more appropriate articles. 129.170.202.243 07:02, 17 January 2007 (UTC)
replies: text: Good idea. No sense in having 3 different article about the same thing. I'm curious, since the grapfruit is a hybrid of the pummelo, does pummelo juice also have the same effect? Or is this some freak aspect of hybridization? --Calibas 00:51, 24 January 2007 (UTC)
thread_title:  Solution to Grapefruit/Grapefruit juice/List of drugs affected by grapefruit

message: Millions of Americans taking statins like Lipitor are warned to avoid grapefruits. They apparently contain a dangerous bitter acid (which apparently is not found in any other citrus fruit) that interferes with statins. --dunnhaupt (talk) 20:10, 11 December 2008 (UTC)

message: The following text: "Grapefruit peel oil is used in aromatherapy for its fat-disgregatingTemplate:Huh??? properties[citation needed] helping against cellulitis and it is historically known for its aroma.[31] Its high vitamin C content also promotes the synthesis of new collagen, helping improve skin tone. It also improves blood circulation and stimulates the lymphatic system to drain toxins from the body."
contains much unsourced material that frankly sounds like crap. E.g., vitamin C is not soluble in oil, so how could it be found in grapefruit peel oil?  Suggest deleting all but "historically known for its aroma."

thread_title:  growth 

message: There is a sentence in Nutritional Value that may have to be changed. It states that "Grapefruit contains large quantities of a simple polyamine called spermidine, which may be related to aging." It goes on to develop the benefits of spermidine as it relates to slowing the aging proccess.
HOWEVER, when you click that very link to get the spermidine page, it says:
" There is a popular myth that grapefruits contain high amounts of spermidine, which probably relies on the confusion between spermidine and putrescine. While citrus fruits show high amounts of putrescine, they contain very little spermidine."
Shouldn't this be changed in the Grapefruit article then?  — Preceding unsigned comment added by 71.224.205.24 (talk) 06:13, 29 January 2014 (UTC)
