Is this a valid study? (most dietary studies are pretty poor) Is it the lack of sugar or is that people who don't put sugar in their coffee have a bunch of other things they do? Maybe people who don't put sugar in their coffee are less likely to eat donuts. Maybe people who don't put sugar in their coffee are more likely to workout. Maybe people who don't put sugar in their coffee are more like to have better genes for T2D and that same collection of genes makes the predisposed to not put sugar in their coffee. I'm not saying sugar isn't bad. It is! (I don't put sugar in my coffee) But, 1 teaspoon a cup doesn't sound like enough to have a measurable impact without knowing that everything else about the people is the same. Reminds me this podcast https://podcast.clearerthinking.org/episode/252/gordon-guyatt-evidence-based-medicine-and-its-discontents/ https://podcast.clearerthinking.org/episode/252/gordon-guyat...

Also: Does the addition of milk to coffee nullify or reduce its antioxidant effects, the way it reportedly does to tea?
- card_zero 2y ago
  Does "antioxidant" there just refer to tannin, really? If you like tea strong, it's necessary to add some milk to bind to some of the tannins so it remains drinkable and doesn't try to turn your esophagus to leather.

    > it's necessary This is silly, many societies drink tons of strong black tea without polluting it with milk or sugar, and do just fine. (I come from one, and have never had any problems with my esophagus — maybe it has already turned into leather without me noticing?) It does often cause nausea on an empty stomach, though, so filling it with something first might actually be useful.

      Hi Kazakhstan! Yeah, I guess one can adapt, but I think there's such a thing as excessive antioxidants, is all I'm saying. Neutralizing some percentage to taste isn't going to stop you getting the healthsome goodness of tea, along with its fluoride for cavity protection (and possible lead or cadmium content, just to even things out).

      you don’t need milk per se. you just need something that your body can digest alongside the tannin. i love strong tea and have had to be saved more than once from cramping and dry heaving from tannin overload.

    I don't think so. I remember hearing about it when some study came out, but can't find the exact reference.

      The Viennese often add whipped cream on top.
    - coldtea 2y ago
      Austrians do it ("einspänner" and "melange") - Germans and French will have that (called "wiener" style or "vienois"). Italians have their "Espresso con panna" (literally: "Espresso with cream") - would also use. The Swiss will often take their coffee with cream too. In Czech republic it's "kafe se šlehačkou", in Greece it's common in capuccinos or added at will to black coffee. Whipped creme is perhaps the most common form (cream + sugar whipped). Not sure about "half and half" though, think that's just an American thing / product.

      In Finland it's customary to have cream for coffee in "fancy" situations. At home everyone just drinks it black or with (oat)milk. But if you want it to taste better, just add a bit of cream =)
  - globular-toast 2y ago
    Where? I've been most places and never encountered this. It should be noted that in the US "half and half" is popular which isn't a thing in Europe but would be referred to as "cream" by Americans.

It’s a study with Walter Willett and Frank Hu, who are probably the most highly regarded nutritional researchers working in the field. Here’s a great video about how these researchers are using big data to reveal insights into nutrition: https://www.youtube.com/watch?v=X8JQtwLNKXg https://www.youtube.com/watch?v=X8JQtwLNKXg

Maybe putting sugar into your body without fiber has never happened in the history of human nature, and it's fool-hardy.

    Not much of eating it alone! But, good point I forgot about.

Coffee and sugar are like oil and water: you can try all you want to mix them but they will never form a whole. No matter how long you stir it... you take a sip, and there's a coffee flavor over here and a sugar flavor over there.
- iKlsR 2y ago
  Disagree, I use a tsp of cane sugar in mine, you can't agitate it efficiently by hand and it needs to be piping hot to help it dissolute. You need something like a cheap $10 handheld milk frother/mixer or something that can get into it better than your hand going anti-clockwise. I typically add a small amount of hot water and get a thick sweet enough paste then add more hot water if I'm doing instant and for ground the same but add a strain step at the end.

Regardless of how valid the study is, it is most likely useless. These kinds of studies have been done for decades and type 2 diabetes rates have only gone up. There has been clear evidence for decades that obesity and high carb diets increase risk of diabetes. Comparing tea to coffee or Skittles to m&Ms is a useless research project as far as diabetes goes. Because it is extremely unlikely that someone will discover that the cure for diabetes was a small change in lifestyle like that.

Why would sugar be bad?
- snapplebobapple 2y ago
  Diabetes is a problem with blood sugar regulation which is primarily accomplished via insulin regulation. if you have a problem regulating something it is almost always best to minimize both the amount and variability of use of that thing. The long answer is, in our time of great abundance, the most common version of type 2 diabetes by a mile is the one where blood sugar is always elevated because fat cells have stopped responding as well to insulin and insulin is also always elevated. Elevated insulin stops energy release from fat cells and keeps fat cells absorbing glucose and storing it as fat for as long as they can until they get large, unresponsive and usually start releasing inflammatory chemicals (aka they start causing you a bad time) thats when insulin jacks up further and once jacking insulin up stops working you now get classified as having type 2 diabetes. so in so far as our fat cells are not highly responsive to insulin, sugar is bad and inso far as sugar contributes to your fat cells getting unresponsive to insulin over time it's bad too (barring a famine that being at maximum fatness will help you survive).

I agree with you that dietary studies, particularly radically new findings, should be considered with appropriate skepticism. But it sounds like you're dismissing all science out of hand! What are we left with then - truthiness? Is there any indication that this study is a poor one? It seems to have a lot of positive indicators. It also generally agrees with what we already "know" about both coffee and about sugar. > I don't put sugar in my coffee We're on the same page. AeroPress?
