>Sugar is glucose plus whatever and is safe in moderation.
Lots of things that are addictive or considered a drug can be safe in moderation.
>Caffeine is a stimulant drug that you cannot give pregnant women at all and it gives you physical withdrawals if you try to quit.
Well that's just not true and I'd caution you to not speak in absolutes. Pregnant women can have finite amounts of caffeine. We just had our first child and my wife's doctor cleared her to have a cup a day during her pregnancy. A cup a day is, as far as I can tell, commonly considered OK[0].
"Current guidelines from the American College of Obstetricians and Gynecologists (ACOG) and other experts say that it's safe for pregnant women to consume up to 200 milligrams of caffeine a day, or around one daily 12-ounce cup of coffee."[1]
The conclusion for the first article you linked is:
> Avoiding caffeine as much as possible is your safest course of action. If you must get your fix, it is best to discuss this with your healthcare provider to make the healthiest choice for you and your baby.
If caffeine isn't so addictive then it should be no problem to give it up for pregnancy :)
Caffeine crosses the placenta to your baby which cannot metabolize it. There are numerous studies of how caffeine causes birth defects. I'll change my absolute but it doesn't really deter from my point that caffeine can be harmful drug in some scenarios (pregnancy) even when drinking it moderately (2-3 cups a day).
Sugar seems to stimulate as well. Perhaps not in the same sense as caffeine?
And I've definitely experienced sugar withdrawals that felt physical when I reduced my refined sugar intake. Could those have been psychological, but just felt physical? Psychosomatic - is that the right word?
Caffeine is a stimulant drug that you cannot give pregnant women more than a cup a day and it gives you physical withdrawals if you try to quit.
