Lao food is one of the healthiest cuisines in the world. The herbs and spices typically used are credited with preventative and curative properties. MSG is rarely used, unlike in most Thai food. Medical findings confirm that lime juice, chilies, garlic and onions – used almost universally in Lao food – as well as lemon grass, galangal and kaffir lime are useful in lowering cholesterol and controlling blood pressure: all have anti-oxidant properties as well.
