Serving size, prep, and portion notes for black coffee
Black coffee is the classic high-caffeine trigger: it sits at the top of the caffeine scale, and a single cup delivers roughly 80 to 120 mg. For sensitive people that is enough to spark jitters, a racing heart, anxiety, disrupted sleep or a sudden dash to the bathroom. Coffee is also naturally acidic, a separate issue for reflux and sensitive stomachs even though the acidity is not a histamine or salicylate problem. The upside is that black coffee is otherwise clean, with no gluten, lactose, FODMAPs or nightshade, so if caffeine is your trigger, moving to decaf keeps almost everything you like about the cup.
Watch for
Very high in caffeine (roughly 80 to 120 mg a cup), the main driver of jitters, palpitations, anxiety and broken sleep / Naturally acidic, which can aggravate acid reflux, GERD and a sensitive stomach independently of the caffeine / Caffeine is a diuretic and gut stimulant, so coffee often triggers urgency or loose stools on an empty stomach / Decaf still contains a little caffeine (usually 2 to 5 mg a cup), not zero, but low enough for most caffeine-sensitive people
