Mothers who consume diets rich in a form of the B vitamin, niacin, give birth to babies at low risk for developing eczema by age 12 months, according to a study from the University of Southampton, UK. The researchers assessed the amount of nicotinamide and related tryptophan metabolites that can be converted to that form of niacin in 497 pregnant women. That information was compared to rates of eczema in their children at ages six- and 12-months. Results showed that babies of mothers with high levels of nicotinamide had a 30% lower chance of developing atopic eczema at 12 months. The researchers suggest that nicotinamide improves the overall structure, moisture, and elasticity of skin, therefore potentially altering the disease process associated with eczema.
