Health effects of wine

Is wine fattening? Freeknowledgecreator (talk) 04:30, 18 January 2020 (UTC)

Wine does contain some calories from sugar and some from alcohol. So whether it causes weight gain (which I assume is what you mean by the phrase "fattening" rather than meaning it specifically produces fat) would depend on what you compare it with. Water and coffee or tea with no additives would contain fewer calories, while something like a milkshake would contain far more. The conditioned response discussed in the previous question could also apply here. You might also read up on the Mediterranean diet, as wine is an important component.NonmalignedNations (talk) 04:45, 18 January 2020 (UTC)

Beer is known for being caloric. But have you ever heard someone called a "wine-belly"? ←Baseball Bugs ^{What's up, Doc?} carrots→ 10:01, 18 January 2020 (UTC)

The idea that any drink or foodstuff is fattening depends only partly on the number of calories it contains. If insufficient exercise or activity is undertaken to 'burn' the calories consumed then any drink or foodstuff will be fattening. Only liquids or foodstuffs with zero calories are not 'fattening'. @Bugs, a beer belly has little relationship with beer consumption. I'm sure we all know someone with a "water melon" (as they say in Andalusia) who drink moderately or not at all. Richard Avery (talk) 11:51, 18 January 2020 (UTC)

Not sure how reliable, but see Calories in Red Wine: Do They Really Matter?. Alansplodge (talk) 21:01, 18 January 2020 (UTC)

Similar arguments could be made for white wine. NonmalignedNations (talk) 06:33, 19 January 2020 (UTC)

Quantitative connection of electronic effects in structure of substances to bond energy

What is the quantitative connection between the strength of the inductive effect, electromeric effect, mesomeric effect and bond energy and/or bond polarizability/electric moment? Thanks.--109.166.137.226 (talk) 23:53, 18 January 2020 (UTC)

You can drop electromeric effect as a specific independent idea. Per IUPAC, "The term has been deemed obsolescent or even obsolete (see mesomeric effect, resonance effect)". DMacks (talk) 18:07, 19 January 2020 (UTC)

Taking the mentioned aspect into consideration, how can these effects be connected to a bond dissociation energy from homolysis (chemistry) or heterolysis (chemistry) or perhaps difference of heats of hydrogenation(addition(s)), theoretical (based on assumed fixed double bonds) and experimental?--109.166.139.194 (talk) 21:16, 21 January 2020 (UTC)
