Summary

This product is a minimally processed flour made from fortified wheat, which provides essential nutrients like calcium, niacin, iron, and thiamin. The processing level is low, and it does not contain any harmful additives or seed oils. However, as a refined flour, it lacks the fiber and nutrient density of whole grain alternatives, which slightly impacts its overall healthfulness.

Calcium carbonate
Neutral

Calcium carbonate is added to fortify flour with calcium, an essential mineral for bone health. It is a common fortification agent in many food products. However, it does not provide additional nutritional benefits beyond calcium fortification.

Risks

Excessive intake may lead to hypercalcemia, but this is unlikely from fortified flour alone.

Benefits

Contributes to daily calcium intake, supporting bone health.

Iron
Neutral

Iron is an essential mineral added to flour to prevent anemia and support oxygen transport in the body. Fortification helps address common dietary deficiencies. However, it does not provide additional benefits beyond its role in preventing deficiency.

Risks

Excessive iron intake can lead to toxicity, but this is unlikely from fortified flour alone.

Benefits

Essential for the production of hemoglobin and overall energy levels.
