Blue 1 is a synthetic compound with no nutritional value added in processed foods just to increase their attractiveness. Although Blue 1 is approved by the FDA at a daily level of 12.5Â mg/kg per person, scientists demonstrated through several studies that this additive was toxic and carcinogenic. Blue 1 can penetrate the blood stream and lead to chromosomal aberrations, or neurotoxicity. This is particularly alarming for infants whose blood- brain barrier is not fully developed. While further researches are being conducted to assess the safety of food dyes, Blue 1 in infantsâ€™ formulas should be taken into consideration. Sources:
