message: You can merge with Daily Values if you like -- SO LONG as searching by RDI still brings up this page.  Daily Values sounds like some British thing and Merkins ain't gonna know to look there.

replies: text: DVs are for labelling. For some nutrients, the DV is the RDA (treat is as a minimum). For other nutrients, the DV is the UL (treat it as a maximum). I think we could merge the pages as long as we make that clear. 142.119.100.34 (talk) 23:45, 12 May 2024 (UTC)
thread_title: Merge with daily values?

message: I'm currently working on a template box with nutritional information: template:nutritionalvalue. I'm considering to add a link to this page with a more extensive list of RDA values (including age groups etc.), and maybe also the equivalents for different countries. Would this be appropriate? Are there for example copyright issues if you reproduce all the data from the official list? Han-Kwang 21:02, 24 June 2006 (UTC)
thread_title: Add a list of values

message: RDI/RDV is meaningless, because there are so many variables that determine what a persons intake should be, such as their gender, weight, age, activity levels, etc. that there is no possible way to determine what an average daily intake should be.Davez621 13:59, 2 September 2006 (UTC)
replies: text: The FDA tables give different values depending on age group and sex. If you look up the numbers, you will see that generally 25-year-old men have the highest need, and that usually these values are taken as a "Daily value" on nutritional labeling. Wikipedia is not a place for primary research, but if you can provide a reference that supports your concern, it could be mentioned in the article. Han-Kwang 00:13, 3 September 2006 (UTC)
thread_title: Completely meaningless

message: :I am suggesting that the page concentrate first on definitions of related terms (they are confusing) and then include the information from the joint US and Canada attempts to determine adequate daily input and toxic levels for nutrients. A separate section could include discussion of similar tables for various other nations and the EU. A reference should be included for each of these summary documents. The summary documents contain references to the specific research documents, which should probably not be cited in the Wiki.
:The RDI and DV are intended to show Adequate Intake for 97.5% of the apparently healthy population, subject to age group, sex, caloric intake, water intake, exercise level, and balance between nutrients. Most of this information is ignored by the public, because the easily available information (Food Labels) is the DV across all age groups, sexes, 2000 kcal (dietary calories) intake, 2.7 liter/day water intake, and an exercise level to balance a 2000 kcal intake. 
:Food labeling should be a secondary or tertiary priority. The first priority should be to define the different terms and how they relate (RDA, RDI, DRI, DV, UL and so on)Background Paper: Framework for DRI Development http://iom.nationalacademies.org/~/media/Files/Activity%20Files/Nutrition/DRIs/New%20Material/11Bckgrd%20PaperFramework%20for%20DRI%20Devel.pdf . The tables showing the DRI (adequate daily intake for 97.5% of the population) divided by age range and sex and the UL (Upper Limit of daily intake before toxic effects begin to appear) would be much more helpful than the tables currently in the page.

thread_title: =Not Meaningless

message: A male adult souild consume 400 calories a day.ГόΙΟ —Preceding unsigned comment added by 90.240.144.179 (talk • contribs) 
:I think a normal value is more like between 2000 and 3000 kcal/day, but it is very dependent on the type of physical activity of a person. Unlike the RDI values for minerals and vitamins, where a 50% extra intake does little harm, a 50% extra energy intake has a very significant effect on body weight. I therefore don't think calories should be listed together with vitamins, although I'm not sure about the opinion of the organisations which establish the RDI values.

thread_title: Energy intake

message: What is the difference between this article and Dietary Reference Intake. They both appear to be about the same thing.--DustWolf (talk) 22:46, 20 August 2008 (UTC)
replies: text: I agree. The situation with all these subtly different notions (RDA, RDI, DV, RDV, DRV), with meanings shifting in time, is already confusing, and having two articles adds to the confusion. Therefore I propose that the two be merged (see Talk:Dietary Reference Intake#Merge proposal). I hope that this merge can be executed by someone who knows the subject matter and can do a better job in explaining the relationship between these TLAs than the current articles. BTW, most dictionaries list Recommended Daily Allowance as the first or only meaning of RDA (for example Stedman's Medical Dictionary and The American Heritage Abbreviations Dictionary), but, although Recommended Daily Allowance redirects to Dietary Reference Intake, this name is not mentioned at all in these articles and its meaning remains unexplained.  --Lambiam 06:12, 4 August 2009 (UTC)

text: Yes confusing. This may help. In the United States DRI = Dietary Reference Intake, which includes Adequate Intake, Estimated Average Requirement, Recommended Dietary Allowance and Tolerable Upper Intake Levels (AI, EAR, RDA, UL). RDI = Reference Daily Intake, which is used for labels on food and vitamin/mineral supplements, expressed as a percentage of Daily Value. RDIs were originally set using the 1968 RDAs. RDAs have been repeatedly revised, but RDIs (and hence labeling) was frozen at the 1968 numbers.  The most extreme example is the vitamin biotin. 100% DV (from the RDI) is 300 micrograms, whereas over time the RDA has been revised downward to 30 micrograms.David notMD (talk) 11:18, 12 March 2016 (UTC)

text: May 20, 2016: FDA announced new RDIs. Food and supplement labels required to be in compliance by July 26, 2018, but can do so sooner. Examples: Thiamin RDI and hence 100% Daily Value changed from 1.5 mg to 1.2 mg. Biotin changed from 300 to 30 micrograms.David notMD (talk) 21:49, 20 May 2016 (UTC)

thread_title:  Conflicting Value in Sodium Article 

message: The recommended minimum intake (DRI) of sodium in the US and Canada for an apparently healthy adult is 500mg/day. Eating only meals cooked from scratch without any added salt can result in a daily sodium intake below 100mg/day. DRI Values Summary  http://iom.nationalacademies.org/Activities/Nutrition/SummaryDRIs/DRI-Tables.aspxBackground Paper: Framework for DRI Development  http://iom.nationalacademies.org/~/media/Files/Activity%20Files/Nutrition/DRIs/New%20Material/11Bckgrd%20PaperFramework%20for%20DRI%20Devel.pdf
The recommended maximum intake (UL) of sodium in the US and Canada for an apparently healthy adult is 2300mg/day. This assumes 2.7 liters of daily water intake (including the water in food, the water obtained by metabolism, and drinking almost 2 liters of water per day) and assumes a low level of sweating and an adequate potassium intake. Past UL for sodium have ranged between 2000mg and 2800mg per day. The UL is an estimate of the upper intake level that not known to pose any risk. The primary risk of high sodium intake is high blood pressure (hypertension). 
Initially, hypertension does not usually have any symptoms, thus the recommendation that people get their blood pressure checked at least once every 6 months (long term hypertension threatens the heart, kidneys, blood vessels, and brain). The median daily sodium intake among apparently healthy US adults is over 3400 mg, most adults in the US have a low potassium intake and the median daily water intake is far below 2.7 liters. This puts over half of the US population at risk for hypertension. Trends in the Prevalence of Excess Dietary Sodium http://www.cdc.gov/mmwr/preview/mmwrhtml/mm6250a1.htm
To adjust for sweating, one needs to increase water intake to compensate for exercise or high temperatures. For an average adult, jogging causes around 2 liters of sweat per hour, while heavy exercise can result in as much as 4 liters of sweat per hour. An additional 800 to 900 mg of sodium intake is required for every extra liter of water intake see Perspiration.

thread_title:  Clarification of Sodium Intake 

message: I find the subject confusing because there are so many very similar concepts, many with similar acronyms (RDA, RDI, DRV, DV, AI). A very careful explanation is needed to avoid confusing the reader and the article isn't great in that respect.
I suspect 99.9% of people don't need to know what an RDI is. Instead, they want to know what the Daily Value (DV) is. The %DV is, after all, what people see on food labels. 'Daily Value' redirects to this article so it's unfortunate this article focuses more on the RDI. The NIH explains Daily Values as follows, and it seems a lot clearer than wikipedia's RDI/DV article.
Note that RDIs are not mentioned at all! Maybe DV should have its own article or this article should be reworked to introduce DV first and, for those who want to go into that detail, introduce the RDI later.

thread_title:  Still confusing and DV is what most people want to understand, not RDI 

message: The chart implies that a good diet (for most people) is one that keeps every nutrient within the range between RDA and UL.
* But then what about RDI, where does that fit in? Is it just a more recently-updated version of RDA?
* I suppose that DV is a number used on labels, which for some nutrients is the RDA, for others the UL, and for others just a suggestion (i.e. the exact ratio of fats & carbs is less important than the total calories, protein, vitamins and minerals).
* Is DRI the larger set that includes RDA, RDI, DV and UL?
