Unlike wheat flour, rye flour has a lower glycemic index, making it a preferred option for people monitoring their blood sugar levels.
Rye flour contains soluble fibers (about 15% of its composition), which help maintain digestive health and contribute to normalizing blood sugar levels.
Additionally, rye flour is rich in vitamins and minerals such as magnesium, phosphorus, and B vitamins. These substances play a vital role in metabolism and maintaining the nervous system.

Rye flour has a glycemic index that varies from 50 to 65.
Glycemic load (GL) is also significant, so it is recommended to combine it with protein and fat-rich foods to reduce the overall impact on blood sugar levels.
Overall, while rye flour is considered a healthier alternative to white flour, it is not an ideal choice for a keto diet. It contains more carbohydrates than needed to maintain ketosis.
Including rye flour in a keto diet may be justified in rare cases, but it is better to focus on low-carb alternatives such as almond or coconut flour.
