Sources of lycopene

The current "sources" section is redundant with the references section. Instead, there should be a sources section that gives a listing of fruits and vegetables that provide significant amounts of lycopene, and the concentrations in each. And someone please, please trim down this article. --LostLeviathan 00:42, 20 May 2006 (UTC)

so you are saying that tomato ketchup contains about 3 to 13 times the amount of lycopene contained in a raw tomato? how many thousands of liters of tomato ketchup are we talking about here? — Preceding unsigned comment added by 92.40.253.123 (talk) 20:25, 12 February 2013 (UTC)

I think the "Dietary sources of lycopene" table may have the quantity column mislabeled, using "ug" (micrograms) per g (gram) rather than mg (milligrams) per gram.69.254.138.16 (talk) 23:55, 27 September 2013 (UTC)

Yes. I changed it. So it in accordance with other sources, including the third external link. Andres (talk) 13:30, 19 April 2014 (UTC)

I think ug/g is more realistic - e.g. how can GAC contain 2000-2300 mg/g? That's over 2g/g which is clearly impossible. — Preceding unsigned comment added by 86.30.57.15 (talk) 22:26, 9 June 2014 (UTC)

Dietary and healt promblems from lycopene

Does anyone know any health promblems caused by lycopene? My father says that he cannot sleep properly if he eats any food containing lycopene. There are some other people who conform my father's observation.--Hannu 08:44, 29 June 2006 (UTC)

Americentrism

article states "Almost all lycopene in the American diet comes from tomato-containing foods."

so what? I'm not American, and I want to think Wikipedia is serving my needs for information. Perhaps put it under some section or separate article on American / international comparison of dietary habits. but take it out of here I think.—Preceding unsigned comment added by 218.186.9.4 (talk • contribs)

You're right, I have removed the sentence. --Dirk Beetstra ^{T C} 17:46, 29 August 2006 (UTC)

Plastic pitted by tomato acid?

The article suggests that plastics can be pitted by tomato acid. Not likely! --Slashme 08:26, 7 November 2006 (UTC)

Orange tomatoes are more bio available lycopene than red!

this should be included somewhere: see this news article.

I've added a brief mention at the end of Dietary sources. Rod57 (talk) 12:08, 20 June 2009 (UTC)

Section order

First, wouldn't it make more sense to describe the "Nutritional benefits" of lycopene before listing its "Dietary sources"? Coming into this article knowing nothing I read the dietary sources thinking, "that's nice, but why should I care where I can get it?" Secondly, the only fact in the "Production" section is that it's also found in a specific fungus...Is there any reason why that cannot also be within the "Dietary sources" section? If there are no objections, I will edit the article as such. -Verdatum (talk) 07:05, 2 February 2008 (UTC)

Lycopene in hawthorn berries....???

There is little info of lycopene in hawthorn berries from literature and hopefully, more scientific researches for this are required.--124.78.208.145 (talk) 12:48, 9 May 2009 (UTC)

Molecular Formula

There seems some mistake. The molecular formula C₄₀H₅₆ (molar mass: 536.87 g/mol) is same for following molecules-

• Carotenes
  • α-Carotene
  • β-Carotene
  • γ-Carotene
  • δ-Carotene
  • ε-Carotene
• Lycopene

How can that be possible? ABHIJEET (talk) 07:49, 24 November 2013 (UTC)

They are isomers. Andres (talk) 13:28, 19 April 2014 (UTC)

Lactolycopene

Hello, I'm new to Wikipedia editing and am trying to learn how to add new material. I added a small section on lactolycopene/ateronon to this article earlier but I think someone has removed it. Please could I have some feedback on where I am going wrong with the content I'm posting? Many thanks — Preceding unsigned comment added by 86.188.154.214 (talk) 11:30, 2 December 2014 (UTC)

In general, and especially for medical content, Wikipedia prefers secondary sources; the guidelines for health-related content are set out at WP:MEDRS. I took a look at the ateronon article and that had problematic sourcing which I trimmed, and added some content from NHS Choices. From that it seems this is just another dietary suppplement marketed with over-promised benefits. This product is itself perhaps a little too tangential even to mention here in this article? Alexbrn ^{talk|contribs|COI} 12:37, 2 December 2014 (UTC)

Agreed... to the IP, adding: it's generally insufficient on Wikipedia to source medical claims to primary sources, or to publicity or popular press articles based on studies. Also the URL to Cambridge's website regarding Cambridge's own study isn't sufficiently independent to be able to establish weight. Zad68 03:00, 3 December 2014 (UTC)
