Carotenoids and Breastfeeding
by Anne Eglash MD, IBCLC, FABM
Few people would argue with the statement that vegetables and fruit are good for us. We are told that eating more produce reduces various health risks such as high blood pressure, heart disease, stroke, and various types of cancers. Carotenoids, which are antioxidants responsible for the yellow, orange, and red colors of various fruits and vegetables, appear to protect us from several diseases. Carotenoids are also found in egg yolk, trout, and salmon. There are approximately 50 different types of carotenoids in the human diet, but 95% of the carotenoids found in human blood include beta-carotene, alpha-carotene, lycopene, beta-cryptoxanthin, lutein and zeaxanthin.
A recent study found that increasing carotenoids in the maternal diet increases the amount of carotenoids in breastmilk. These same authors have outlined the role of carotenoids in pregnancy and infant health, which is our current topic.
Carotenoids have their highest concentration in colostrum, causing its deep yellow color. The carotenoid concentration in breastmilk decreases by the third week, during the mature milk stage when the milk turns white. After this time, the level is dependent on the maternal diet. Carotenoid levels are highest in breastmilk fat. Infant formulas are not required to contain carotenoids, although some do. Humans cannot manufacture carotenoids on their own, so they must come from the diet. People who consume a diet heavy in carotenoids may have a yellowish hue to their fat just under the skin, such as on their palms and soles. Infants who love carrots and sweet potatoes also display carotenemia, typically evidenced by their bright yellow noses. This is a benign condition.
Carotenoids are considered anti-oxidants, which play a role in reducing the effects of oxidative stress in the human body. Oxidative stress, such as decreased blood flow to the fetus or maternal tobacco use, causes bodily damage, contributing to the risk of infant illness such as necrotizing enterocolitis, respiratory distress syndrome, and bronchopulmonary dysplasia.
- Carotenoids have their lowest concentration in the brain.
- Lower maternal serum levels of carotenoids has been found in some research to be associated with preterm birth.
- High maternal plasma levels of carotenoids is associated with less risk of small-for-gestational-age status of the newborn.
- Carotenoids promote optimal retinal development and help to prevent retinal damage in infants.
- There is good evidence that carotenoids help prevent pre-eclampsia.

The traditional base for so many French recipes is a sauté of onion, carrot, and celery. Wild carrots form the root of “Queen Anne’s Lace” which grows in the fields and along roadways. I wonder if it too contains carotene; it’s white.

Very good information for all ages. Clear science to help encourage mothers to breastfeed.

Does this mean a nursing mother eating a substantial amount of spinach everyday will increase the carotenoids in her breast milk and may be a factor contributing to cause a 1.5 year old toddler to have yellow or orangey soles aside to her(toddler) eating pumpkin and carrots?

The spinach in her breastmilk will increase the carotenoids in her breastmilk. I have no idea if that would be sufficient to markedly increase the amount of carotenoids in the infant’s subcutaneous tissue. I have not seen studies on this.
