Spelt is the best grain, warming, lubricating and high of nutritional value. It is better tolerated by the body than any other grain. Spelt provides the consumer with good flesh and good blood and confers a cheerful disposition. It provides a happy mind and a joyful spirit. No matter how you eat spelt, either a bread or in other foods, it is good and easy to digest.... If someone is ill boil some spelt, mix it with egg and this will heal him like a fine ointment.... Spelt porridge, spelt bread and spelt coffee constitute the ideal breakfast.... Spelt is the food of the future.
--Hildegard von Bingen, 1133
One of the oldest cultivated grains (since 5000 B.C.), Triticum spelta, it's an ancient cousin of modern wheat ( Triticum aestivum). Nutritionally, it has large amounts of B complex and 10 to 25% more protein content than the common varieties of modern wheat. More popular in Europe than the United States, spelt is known as farro in Italy and dinkle in Germany. The Swiss probably introduced it to North America, and it was cultivated in the U.S. (acreage peaked in 1909) but its tough hull made processing difficult, and other varieties of wheat (bred for higher gluten content and easier threshing) supplanted it. It is still grown for feed, and organic spelt is popular with natural food companies (you can find spelt pastas, spelt cookies, spelt flours and muffin mixes at health food stores).

Though it does contain gluten, people with sensitivies and wheat allergies report being able to tolerate spelt without side effects-- but consult your doctor if you want to try it.

Spelt berries can be cooked like wheat berries.
