Ingestion of oat bran in excessive doses can lead to more health problems than advantages:

It is necessary to ingest abundant amount of water together with the oat bran to avoid the secondary problems that the ingestion of this supplement can originate.

Water softens fiber and facilitates its passage through the intestine. It is advisable to drink at least a couple of liters of water if this fiber supplement is included in the usual diet.

An excess of non-soluble fiber can produce intestinal problems such as diarrhea, belly swelling, flatulence or even intestinal occlusions.

Accelerating intestinal transit with fiber supplements such as oat bran can produce nutrient deficiency if it is prolonged for some time.

In case of osteoporosis, it is recommended not to take bran to avoid that this supplement inhibits the absorption of calcium (Phytates of the oat bran could reduce the absorption of this mineral). In these cases, oat flakes are more suitable.

Contraindications of bran for anemia

People with anemia should not take fiber supplements because these products are very rich in phytates, antinutrient substances that prevent the absorption of minerals such as iron, zinc or calcium by preventing their absorption (mineral thieves).

For this reason people with anemia or problems of mineral absorption should not take these fibers.
