National Coffee Ice Cream Day (September 6) stacks a GL-zero beverage and a high-GL dessert: black coffee runs GL 0 per 100g, while vanilla ice cream carries a real load — the scoop decides the number.

The Day and the Stack

National Coffee Ice Cream Day (September 6) is a two-ingredient holiday, and the two ingredients sit at opposite ends of the GL ladder. Black brewed coffee runs a glycemic load of 0 per 100g — the drink itself is essentially carbohydrate-free. Vanilla ice cream is the opposite: sugar and dairy cream, with a GL that climbs with every scoop.

The Coffee Half Is Free

The coffee portion of the day costs nothing on the glucose ledger, as long as it stays black or takes a splash of milk rather than sweetened creamers. That is why coffee shows up so often in favorable diabetes patterns — the beverage is neutral, and the benefits (if any) come with the caffeine and polyphenols, not the sugar.

The Scoop Is the Number

The ice cream half is where the GL lives: a standard vanilla scoop carries a moderate-to-high load depending on portion, and 'light' or 'low-fat' versions trade fat for more sugar per gram. The measured version of the day: one small scoop of regular (not fat-free) vanilla with black coffee — the fat in the cream slows the sugar's absorption, and one scoop keeps the total in the treat range rather than the spike range.
