Ancient Wheats Higher in Healthy Carotenoids

Canadian researchers from the Food Research Program, Agriculture and Agri-Food Canada evaluated several primitive and modern wheat species, and found the highest levels of carotenoids including lutein, zeaxanthin and beta-carotene in Einkorn. Durum, Kamut® and Khorosan had intermediate levels, while common bread or pastry wheat had the lowest levels of carotenoids.  The carotenoids studied are thought to be important to eye health, among other functions.

Whole Grains High In Antioxidants

Dr. Rui Hai Liu of Cornell and his colleagues discovered that whole grains contain protective antioxidants in quantities rivalling or exceeding those in fruits and vegetables. Corn, for instance, has almost twice the antioxidant activity of apples, while wheat and oats almost equal broccoli and spinach in antioxidant activity.

Optimum Germination Conditions for Wheat

Scientists at the University of Alberta germinated wheat under various conditions to determine how to maximize the production of antioxidants.  First, they steeped the grains in water for 24 or 48 hours, then sprouted them in the dark for 9 days. Vitamins C and E and beta-carotene, which were barely detectable in the dry grains, increased steadiily during the germination period. Grains steeped for 48 hours became wet, sticky, discolored and acidic-smelling after germination, leading researchers to conclude that 24 hours of steeping and 7 days of sprouting would produce the best combination of antioxidant concentrations and sensory properties.
