Alfalfa

Alfalfa (Medicago sativa) is a herbaceous perennial plant. It is cultivated worldwide for its high nutritional value, particularly as animal fodder. The edible parts are typically the sprouts and leaves, which are consumed fresh or dried.

Alfalfa is most commonly found in health-focused products such as dietary supplements, smoothies, and herbal teas. It is valued for its nutrient profile, often marketed as a source of vitamins, minerals, and fibre. Manufacturers may include it for its perceived health benefits rather than for a specific technological function in food processing.

Alfalfa is not listed as an authorised food additive on the Register of Food Additive Authorisations in Great Britain, meaning it is typically consumed as a food ingredient or supplement. While generally considered safe, alfalfa sprouts have been linked to outbreaks of foodborne illness (e.g., Salmonella, E. coli) due to contamination during growth or handling. Evidence regarding specific health benefits from consuming alfalfa is mixed, with some studies suggesting positive effects on cholesterol levels or menopausal symptoms, while others show no significant impact.
