On October 25 the Daily Mail ran Erica Lamberg’s article on rhubarb, resting on two clinicians and two studies done in metabolic and laboratory models. Its own closing summary says rhubarb ‘may support’ cholesterol, digestion and liver health. Three verbs do the selling: ‘slashes’, ‘eases’, ‘wards off’. Each is a deed already done, with rhubarb as the doer. The loaded verb turns a maybe into a result. The article’s closing summary uses a different verb: its fiber and plant compounds ‘may support healthy cholesterol levels, digestion and liver health.’ The two experts quoted say ‘can help reduce cholesterol’ and ‘can support a heart-healthy eating pattern’. Neither says ‘slashes’ or ‘wards off’, and neither says rhubarb prevents liver disease. The evidence sits low on the page. The first study arrives in the 11th paragraph: ‘specific plant fractions from raw rhubarb’ tested ‘in metabolic models’, with no count of subjects, no dose, and no word on people or animals. The liver study tested extracts ‘in laboratory models’. Neither paper is linked, and no author or funder is named. The suggested serving, ‘About 100 to 200g, roughly one or two fresh stalks’, is tied to neither study. The ‘$2’ has no source. The headline rides the halo: one good quality stands for all of them. Rhubarb has fiber, and the dietitian says certain fibers can help manage cholesterol, so the stalk borrows that standing for digestion and the liver too. The tell is the gap between verbs: when the headline acts and the expert says ‘can help’, the expert’s verb is the one the evidence carries. The warning about toxic leaves, oxalates and ‘laxative dependence’ comes about 23 paragraphs in.
