What is the difference between white and black poppy seeds?

Answer 1

Actually, very little. Most people cannot tell the difference in taste, and they have virtually identical nutritional value. There is a rumor that black seeds help keep hair from turning grey only -- though I assume this is just an old wive's tale. In terms of usage, black sesame seeds are used more in the Far East in Asian food (often, they coat meat in them before grilling/sauteeing, whereas white are preferred in the Middle East, where they are often ground into tahini.

Answer 2

There are several types of poppy seeds with two of the most commonly known as black poppy and white poppy. The health benefits of white and black poppy seeds are comparable, and the biggest difference is just color of the seed itself.

Answer 3

Black seeds are mature and, if planted, would yield new growth; white seeds are immature and not viable.
