Wheat

At the Swedish University of Agricultural Sciences in Uppsala, researchers fed rye bread (with three varying levels of rye bran) and wheat bread to 16 people, then asked them to rate their appetite (hunger, satiety and desire to eat) for 8 hours afterward. [It’s not known if the wheat bread was whole wheat or refined wheat.] All through the morning and into the afternoon, the three rye bread breakfasts all decreased hunger and desire to eat, compared to the wheat bread control, with the rye bread containing the highest level of bran providing the strongest effect on satiety.

In Ankara, Turkey, scientists at Hacettepe University’s Department of Food Engineering compared 18 ancients wheats (12 emmer, 6 einkorn) with 2 modern bread wheats, to assess their total phenolics and flavonoids, phenolic acids, lutein, total yellow pigment, and total radical scavenging capacities. Results showed “remarkably higher total antioxidant activity” in emmer varieties, and “quite high levels of lutein” in the einkorn samples. In conclusion, the findings were considered to be key to “breeding wheat varieties for higher concentration and better composition of health-beneficial phytochemicals.”
