Neanderthals roasted veggies, and may have used them medicinally

scibri (2544842) writes "The vision of Neanderthals as inflexible carnivores has been used to suggest that they went extinct as a result of food scarcity, whereas omnivorous humans were able to survive. But evidence is mounting that plants were important to Neanderthal diets — and now a study reveals that those plants were roasted, and may have been used medicinally.

Researchers used organic compounds embedded in 50,000-year-old dental plaque to study the Neanderthal diet. The plaque contained a range of carbohydrates and starch granules, hinting that the Neanderthals had consumed a variety of plant species. By contrast, there were few lipids or proteins from meat.

They also found, lurking in the plaque of a few specimens, a range of alkyl phenols, aromatic hydrocarbons and roasted starch granules that suggested that the Neanderthals had spent time in smoky areas and eaten cooked vegetables (Abstract).

Among the compounds found were chemicals from plants such as yarrow and camomile, which taste bitter and have no nutritional value. So why they would intentionally eat them? The researchers think they may have been using them medicinally — the plants are used by modern herbalists as anti-inflamatories and antiseptics."
