Babies Who Start Solids Too Early More Likely To Be Obese

Ideally, babies are exclusively breast-fed for the first six months of their lives. Then, solid food — really, a misnomer since “solids” consist initially of soupy rice or barley cereal — is introduced. But a quarter of U.S. infants are introduced to solid foods before they hit four months.

Why parents disregard the recommendation from the American Academy of Pediatrics (AAP) and the World Health Organization to hold off on solids until six months and what that means for these babies down the road is the subject of two new studies in the AAP journal Pediatrics.

One study, published Monday by researchers at Children's Hospital Boston and Harvard University, shows that introducing solids before a baby's 4-month birthday is linked to a sixfold increase in that baby becoming obese by the time he's 3. This was true for infants whose mothers never breast-fed them or weaned them before four months.

ALZHEIMER'S DISEASE INHERITED THROUGH MATERNAL LINE, STUDY FINDS

A family history of Alzheimer's disease significantly increases the risk for developing this disorder, but a new study in Biological Psychiatry suggests that which of your parents has the disease is very important.

Alzheimer's is the most common form of dementia in late-life, affecting over 5 million elderly in the United States alone. In order to develop preventative treatments, it is necessary to identify those individuals who are at highest risk for developing Alzheimer's.

Although individuals with a parental history of Alzheimer's are at increased risk for developing the disease, the specific biological and genetic mechanisms accounting for this increased risk are not known.

An important consideration may be a phenomenon called genomic imprinting, where the pattern of the inherited disease differs based on whether the risk genes are inherited from the mother or the father.
