Fresh Coconut - cocos nucifera
On my last visit to the Mother & Infant Hospital here in Vientiane, the above was one of my "prescriptions". (I will note, a prenatal vitamin and calcium was also included on the list.) Fresh coconut juice to be consumed daily. My husband (who is Lao) seems more intent on making sure I drink my daily dose of coconuts than my prenatals.
However, there is actually quiet a bit of science to this logic. (I'll leave you to google details, as there is a wealth of info online about the benefits of coconut.) The basic truth is Coconut has long been considered a nutritive tonic amoungst the Southeast Asians. It is often prescribed by traditional doctors for cases of low immunity and low energy.
