Untitled edit
Do the sugar and fat substitutes belong in this list? They are not essential nutrients needed by the body, indeed, many of the sugar substitutes contribute nothing. The definition of macronutrient given on the disambiguation page suggests they do not belong.

Alcohol -- The Fourth Macronutrient edit
Alcohol is the second-most calorically food at 7cal/g, vs 9 for fat. I have included it therefore as a Macronutrient. It does produce energy for the body but is not necessary, just like carbohydrates -- no, they are not totally necessary, the body can produce glucose from protein for the brain. It's certainly not a micronutrient, though it does have a nutritional component. It is a traditional source of energy for much of the world and the current controversy regarding its benefit/harm is not a reason to exclude it. I've googled around for a clear answer but the definitions of macronutrient are vague and variable, especially the wikipedia page. Here is a Univ of Cambridge (UK) journal that supports that it the fourth macronutrient (substance that humans commonly consume that provides a great deal of caloric energy by weight?).: http://journals.cambridge.org/download.php?file=%2FPHN%2FPHN8_7a%2FS1368980005001266a.pdf Maybe it should be made clear it is inessential but does provide energy? . 38.108.125.194 (talk) 19:36, 11 April 2014 (UTC)
- Alcohol should probably be mentioned, albeit with a note of explanation, but the article currently lists water as a macronutrient, which it most certainly is not. And furthermore, the source it cites for that factoid doesn't even mention the word "water" but does mention alcohol as a macronutrient. I'm going to go ahead and change the article now. 202.155.85.18 (talk) 01:28, 12 February 2016 (UTC)
- I added alcohol, as per source. But the next line Macronutrients are defined as a class of chemical compounds which humans consume in the largest quantities (must be above a threshold amount) and which provide humans with the bulk of energy needs an update, the wording humans consume most and must be above threshold amount is very unclear and needs more explanations. --Stefan-S talk
Fibre links to the wrong page edit
The headline Fibre under "Macronutrients that don't provide energy" should link to https://en.wikipedia.org/wiki/Dietary_fiber but it's linked to the generic fibre article instead. — Preceding unsigned comment added by 77.119.130.121 (talk) 09:53, 26 August 2017 (UTC)
Heptadecenoic Acid Is Under Monounsaturated Fat edit
Heptadecenoic Acid appears under monounsaturated fat but is another name for the saturated fatty acid Margaric acid which is also listed under saturated fat. I am no chemist but this doesn't look right. The same goes for Pentadecenoic and Pentadecanoic acid. Giantsponge (talk) 16:13, 15 September 2018 (UTC)
Title change edit
I would rename this article list of human macronutrients as nutrients depends a lot on which species you are considering. And some articles of ecology reference this page wrongly when talking about plants or others. Any objection ? Hidodu (talk) 17:20, 23 March 2022 (UTC)

Oxygen is a macronutrient edit
A quick google search suggests oxygen is a macronutrient. Should it be added? Leitmotiv (talk) 16:47, 4 January 2023 (UTC)
