Did you eat Rye bread?

Rye is a cereal grain that looks like wheat but is longer and more slender and varies in color from yellowish brown to grayish green. It is generally available in its whole or cracked grain form or as flour or flakes that look similar to old-fashioned oats. Because it is difficult to separate the germ and bran from the endosperm of rye, rye flour usually retains a large quantity of nutrients, in contrast to refined wheat flour.

white bread vs whole wheat

Bread is made out of flour that comes from grain kernels — usually wheat. A grain kernel has three parts: the bran, the endosperm, and the germ (so called because it's the part of the kernel that germinates into a new plant).
Whole grains contain all parts of the grain kernel. But refined grains, like the flour used to make white bread, have had the fiber-dense bran and the nutrient-rich germ processed out, leaving only the starchy endosperm. This means that refined grain is not as rich in essential fatty acids, vitamin E, magnesium, and zinc.
