Ginger Beer

Food · Drink · Food, Typed Supps

The most sugary thing in the soft drink fridge, sold on a health-food association.

Stage by stage

Heat, not dose (Taste): The ginger burn is a flavouring effect; the quantity is nowhere near a therapeutic one.
No anti-nausea action (Stomach): Trials used 1–1.5 g of dried ginger daily. A bottle supplies a small fraction of that.
Free sugar (Circulation): 9.8 g per 100 g — the highest of the mainstream soft drinks.
Fructose (Liver): Half the sucrose arrives as fructose, handled hepatically like any free sugar.

What the evidence supports

Settling nausea — insufficient evidence. Ginger itself has reasonable support at 1–1.5 g/day of dried rhizome, but commercial ginger beer supplies an undeclared and far smaller quantity, usually as extract or flavouring.

Timing

Nothing to time. If nausea is the reason, the root or a standardised capsule is the form that was actually studied.

Time to effect

15–30 min: Glycaemic peak.
—: No anti-nausea effect to wait for at this ginger content.

Allergens

None of the fourteen major allergens. Derived from what this food is, not from a product label.

Eating patterns

Fits: Vegan, Vegetarian, Pescatarian, Halal, Kosher, Gluten-free. Depends on the product: Keto, Low-FODMAP.

Environmental footprint

1.2 kg CO2e and 132 litres of freshwater per kg, matched to "Barley (beer)" in Poore & Nemecek (2018), Science 360.

Cost band

Cheap — roughly £2 per kg, as a band midpoint rather than a price.

Food vs. supplement

Ginger is one of the better-evidenced food remedies there is, with real trial support for pregnancy nausea at around a gram a day. Ginger beer is the clearest case in this batch of a product trading on a benefit it does not deliver.

Kitchen tip

Grate a thumb of fresh ginger into hot water. That is what the trials were testing, and it costs a fraction of the bottle.

Common myth

“Ginger beer settles an upset stomach.” In reality: Ginger does, at around 1 to 1.5 g a day — the dose used in pregnancy and post-operative nausea trials. Commercial ginger beer contains a flavouring quantity, usually undeclared and far below that, wrapped around 9.8 g of sugar per 100 g, which is the most of any mainstream soft drink. Fresh grated ginger in hot water gives you the thing that works.
