Talk:Nutrient

The piece I wrote on nutrients in water quality is modified from a similar piece I wrote for my company at [1] (http://www.aecos.com/CPIE/Nutrients.html) and provided with appropriate permission Marshman
Qaz -- um, what? Ethanol (unique among the simple alcohols) is a nutrient; humans can metabolize it for its energy content. The liver converts it to acetic acid which is a glucose breakdown product (see Krebs cycle). Why do you think heavy drinkers tend to get fat? Zack 19:48, 15 Mar 2004 (UTC)
I'm not sure where the division of substances into two groups originated from. Although not "wrong", it is not really all that correct either. I've added a cautionary paragraph, but the whole top section could probably be rewritten. Maybe it just need to be clarified better? Metabolism is primarily energy production, so the terminology seems off - Marshman 06:00, 16 Mar 2004 (UTC)
I don't see fiber mentioned on this page.
- For the same reason you do not see corn chips, t-bone steaks, or green tea. Fiber is a form that biological tissues take, it is not a nutrient per se. - Marshman 23:48, 6 Apr 2004 (UTC)
Many people believe that boiling vegetables makes them lose nutrients. Wikipedia:Reference_desk#Boiling_veg So does it somehow destroy the nutrients, or just leach the nutrients into the water ? Boiling water is not anywhere close to hot enough to destroy minerals (elements) or amino acids or protiens. (Boiling water "denatures" protiens, but they curl right back up again after they cool off). If it's true that all nutrients can survive boiling water, please say that in the article. If some nutrients are destroyed in boiling water, please say which ones in the article. Thank you. --DavidCary 16:19, 18 Jun 2005 (UTC)
- Boiling vegetables in water will remove salts and minerals into the water and will alter proteins, so there certainly is some nutritional value destroyed by the process. But the caloric (energy) content is not changed - Marshman 02:19, 21 Jun 2005 (UTC)
