Exclusive breastfeeding tied to healthier cholesterol in teens



(MENAFN - Jordan Times) Babies who consume nothing but breast milk for their first three months of life may have healthier cholesterol levels by adolescence than infants who drink formula, a new study suggests.

Paediatricians recommend that mothers exclusively breastfeed infants until they're at least six months old because it can bolster babies' immune systems and reduce their risk of ear and respiratory infections, sudden infant death syndrome, allergies, obesity and diabetes. Breast milk does contain more cholesterol than formula, however, and little is known about how this might impact cholesterol levels later in life, researchers note in Paediatrics.

For the current study, researchers tracked 3,261 babies born in Hong Kong in 1997, until they reached an average age of 17.5 years. Overall, about 7.5 per cent of these infants were exclusively breastfed for the first three months of life; another 40 per cent consumed a combination of breast milk and formula and 52 per cent drank only formula.

By their late teens, compared to kids who had some formula as babies, those who did not had lower total cholesterol levels as well as lower levels of 'bad' LDL cholesterol, the study found.

'The differences we saw between breastfed and formula fed infants could be due to differences between the mothers who did and did not breastfeed,' senior study author Mary Schooling of the University of Hong Kong said by e-mail. 'However, the adolescents in our study were born in Hong Kong in 1997 when breastfeeding was not so common and there were few differences between the mothers who did and did not breastfeed.'

Only about 1 per cent of the teens in the study had high levels of low-density lipoprotein (LDL) cholesterol, the type that builds up in blood vessels and can lead to blood clots and heart attacks.

LDL levels were similar for teens who only had formula as babies and teens who were fed a combination of formula and breast milk.

But exclusively breastfed babies had lower LDL and total cholesterol, and lower levels of triglycerides, or fats, compared to babies only fed formula.

Even so, the results add to the evidence that early nutritional exposures — even in the first weeks or months of life — may modify so-called cardiovascular risk factors like cholesterol levels, said Christopher Owen of the Population Health Research Institute at St George's University of London.
