In addition to being an unhealthy oil that's high in saturated, artery-clogging fat, palm oil should be avoided in foods to help protect endangered orangutans. These intelligent animals, found in tropical rain forests in Sumatra and Borneo, are being eradicated as their homeland is cleared to make room for palm tree oil farms. As the rainforest land is cut, orangutans are displaced and killed, and baby orangutans are often left orphaned. To avoid palm oil, look for pure oils like sunflower, olive, corn or coconut oil. Avoid anything labeled "vegetable" oil -- there is a strong likelihood that a high percentage of that vegetable is actually palm.
