Similar to what anthropologist Amanda Henry has said, there are a lot of time periods in the human history but there are only theories to answer questions on what people actually ate then.
Pigs, chicken and water buffalos (carabao) are not only of importance to the Philippine rice economy but are also consumed by many Filipinos.
They highly depend on the herbs, bark and roof of trees, leaves of plants and vegetables for their medicine.
Ancient Filipinos also believe that their health is greatly affected or influenced by the spirits and natural forces around them.
They also believe that skin diseases are brought upon by a ‘theory’ of attachment to the body or sometimes, inherited from past ancestors.
To avoid tooth decay, they chewed betel nut or tobacco because they believe that these kill the “worms” that were brought by drinking water or eating food.
