Limes are thought to originate from the South East Asian region. There are several varieties, two of commercial interest are Persian/Tahitian (citrus aurantifolia) and key lime (citrus latifolia). Lime is complex in terms of all the mutations and hybridisations that have occurred, however, this has brought us our variety in citrus fruits. Key lime is a hybrid of citron and papeda (a wild “parent” citrus). Persian/Tahitian lime is a hybrid of key lime and lemon. They grow in tropical and subtropical climates such as Mexico, Peru and Brazil. The ingredient is a good source of potassium, vitamins A, B, C and D, calcium and magnesium. The high level of vitamin C and antioxidants found in the fruit help support the immune system. Limes are also beneficial for digestion due to their high acid content which help saliva break down food. They are also low in calories which is often why they are formulated into health drinks.
