Q: What kind of corn do people grow in Ghana?

A: We grow dent, flint, and a little sweet corn. The bulk of the corn will be dent corn. We do not grow yellow corn.

Q: Is cocoyam the same thing as taro?

A: Yes. However, in the common literature one can confuse the type of edible aroid, as the same aroid may be referred to with a different name in different locations. The best way of identifying the aroids is through the use of scientific/botanical names. I could send you the common English names and the scientific names if you are interested.

Q: How many kinds of African yam are there?

A: There are several. We can however refer to 4-5 major yam species. These are:

* Dioscorea alata
* Dioscorea rotundata
* Diascorea esculenta
* Diascorea dumetorum

Each of these has a common English name which may vary from place to place. The four listed are the major species. We may have in addition another 6-8 minor species.

Q: What are some papers you have written on traditional African foods:

A:

Elderly individuals should exercise caution when taking Ambien due to the heightened risk of pronounced sedation and/or muscle relaxation.
