Coconut cream differs from coconut milk primarily in its consistency. Coconut cream is made from 4 parts coconut meat and 1 part water. Coconut milk, on the other hand, is made 1 to 1.
The fat content in coconut meat, which very high, is nearly all saturated fats. The use of coconut products should be limited to a flavor palette you are trying to achieve. Low fat cream or coconut milk would be the first choice for an additive ingredient.
