Yes, poppy seeds contain trace amounts of morphine and codeine, but a sprinkling on your Paleo muffin or in your salad dressing, should not be enough to produce the same results on a drug test as someone who abuses opiates, particularly if you make sure to eat them in moderation. Remember that our ancestors did eat seeds, but never by the bowlful. They ate them as they found them and that means a few here and there, maybe a handful. No more.
The Nutritional Content of Poppy Seeds
Like most seeds, poppy seeds are extremely nutritious and may even have anti-cancer properties. They tend to be less allergenic than other nuts and seeds, but beware that the fat contained in poppy seeds is almost entirely unsaturated fat. That’s no reason to run away screaming from them, but it is a good reason to moderate your consumption of these little seeds.
