Your teeth carry secrets: centuries of history about your ancestors, from where they lived to what they ate and where they traveled.

    “O People of the Scripture! Do not exaggerate in your religion nor utter aught concerning Allah save the truth. The Messiah, Jesus son of Mary, was only a messenger of Allah, and His word which He conveyed unto Mary, and a spirit from Him. So believe in Allah and His messengers, and say not “Three”. Cease! (it is) better for you! Allah is only One God. Far is it removed from His transcendent majesty that he should have a son. His is all that is in the heavens and all that is in the earth. And Allah is sufficient as Defender.”
    Holy Quran 4: 171

Hear about her incredible plan to serve delicious, nutritious daily meals to millions of kids across Africa by 2030.
