Chromium is practically destroyed when making white flour.
Chromium alongside insulin keeps blood sugar level at a constant. Should we not have enough chromium then we are susceptible to erratic behaviour and mood swings.
Bran loss can impact on moods. Refined carbohydrates, that is, white rice and white flour products consolidate in the gut, thereby resulting in constipation.
Diets of high refined carbohydrates are low in key nutrients which can lead to irritability and low IQ. This in turn can lead to antisocial behaviour.
