Talk:Cranberry juice

Health Benefits
Under the health benefits section it says that cranberry juice can prevent urinary tract infections (UTIs), however NHS direct clearly states that recent research disproves this theory showing that it is no more effective than a placebo. — Preceding unsigned comment added by 80.229.148.53 (talk) 11:24, 3 November 2013 (UTC)

Concerns over 'Health Benefits' section
I'm a bit worried about some of the sources used in the 'Health Benefits' section. Of particular concern are Basu et al (2011), and Neto (2007). These are the only sources used to support the claims about Cardiovascular Improvement and Prevention of Cancers respectively, but they both appear to be primary sources - clinical research papers. WP:MEDRS makes it clear that claims about biomedical information must be based on secondary sources - which these papers are not. I suggest that these sections be removed unless MEDRS-compliant sources can be found to support them. Girth Summit (talk) 14:33, 30 May 2018 (UTC)
 * I've gone ahead and removed the assertions. They could be reintroduced if stronger sources could be found.Girth Summit (talk) 11:24, 31 May 2018 (UTC)

Pure cranberry juice
Pure cranberry juice is often hard to find and very expensive. 8 fluid ounces of pure cranberry juice contains:
 * 0.3 mg of Iron (2% RDA)
 * 180 mg of Potassium (4% RDA)
 * 0.8 mg of Manganese (35% RDA)
 * 2.2 mg of Vitamin E (15% RDA)
 * 2.0 mg of Vitamin B5 (40% RDA)
 * 0.1 mg of Vitamin B6 (6% RDA)

Nutrition Facts from a case of unadulterated juice. Not a reliable source according to admin. Dana60Cummins (talk) 23:55, 12 January 2021 (UTC)
 * Some of these values are within the standard error of measurement provided in the nutrition table which derived from the USDA National Nutrient Database (used as the reliable source for Wikipedia articles on foods), whereas some are unlikely to be reliable (manganese, vitamin E). No WP:RS is provided by for their assertion that the above data are reliable or for the statement about "pure cranberry juice". Nutrient analysis isn't easy, so we should require a reliable analytical source for nutrient contents.
 * There is nothing "unpure" about a cranberry juice product that has been sweetened to make it palatable and fortified with tasteless nutrients. Perhaps "pure" is a matter of "raw" or "unsweetened", for which the USDA provides an analysis. Zefr (talk) 00:33, 13 January 2021 (UTC)
 * That's not correct. Sugar added is very unpure.  A person on a ketogenic for medical reasons clearly has a consequence of elevated blood sugar.Dana60Cummins (talk) 01:18, 13 January 2021 (UTC)
 * Again, an opinion and WP:OR, now requiring a more stringent WP:MEDRS source. You are on the edge of WP:DE and WP:TALKNO for using the talk page as your forum for unsubstantiated health claims. Zefr (talk) 01:22, 13 January 2021 (UTC)
 * It seems to me that there is a question of semantics here - this article is written on the assumption that cranberry juice is the WP:COMMONNAME for the red liquid typically marketed in the US and elsewhere as 'cranberry juice', which is made from the juice of the cranberry with certain additives including sugar. This meaning is related to, but distinct from, the unadulterated juice of the cranberry, which obviously has a different composition. This is discussed in the article, but I would not be averse to having a bit more explanation of this in the body of the article, perhaps fleshed out a bit in the lead too, if decent sources could be found.

Health Benefits needs updating based on new research
The 2012 meta-analysis got a 2023 update that reversed the conclusion and now states that it does help some groups with UTIs. Jasontherand (talk) 04:36, 29 June 2023 (UTC)


 * The full Cochrane review is behind a paywall (previously, they were open to the public), but this summary provides a general view of the analysis. The authors refer to cranberry "products" (not specifically juice) in the studies of the meta-analysis, so specific relevance to this article on juice is uncertain.
 * The variable nature of studies analyzed leads the authors to state that the certainty of evidence was moderate or low, and the products "probably" reduced the risk of UTI infection - not very convincing statements to change the current status of the article. The 2014 EFSA scientific review was that a cause-and-effect relationship between cranberry constituents and UTI risk could not be proven, This conclusion has not been improved upon since 2014.

overly focused on effects of consumption, needs section(s) on cultural relevance
i don't have the time at the moment to research it so I'm just putting this here hoping someone else will, but at minimum there should be a use section. Koricind (talk) 02:24, 6 September 2023 (UTC)
