Practical
Consumer tips
- 1
If buying Barley, opt for 'hulled' over 'pearled' to keep the bran and maximize fiber.
- 2
If buying Rye bread, look for 'whole grain rye' or 'pumpernickel'—many commercial rye breads are mostly refined wheat flour with caramel coloring.
- 3
Introduce both Barley and Rye slowly into your diet to give your gut time to adjust to the high fiber content and avoid bloating.
- 4
Cook Rye berries like you would brown rice, but allow for a longer cooking time—soaking them overnight helps.
