A study released in the British Medical Journal suggests that obesity during pregnancy has long-term effects on the unborn child. The study found that middle-aged adults who were born to obese mothers had an increased risk of premature death and cardiovascular problems. In the U.S., approximately 35% of pregnant women are clinically obese (BMI >30) at the start of pregnancy.
A new study in Nature Communications suggests that consuming added sugar, even within the recommended guidelines, may be toxic to your health. In the study, mice consuming added sugar in proportion to the recommended guidelines experienced negative effects on survival, reproduction, and competitive ability. Though the study occurred in mice, the results suggest that consuming added sugar, even within recommended levels, can also have detrimental effects on human health.
A study in the Journal of Applied Physiology confirms that the taller you are, the fewer calories you burn for any given walking speed. In order to burn the same number of calories as a shorter person, a taller person will need to walk faster. I wonder if this applies to other modes of exercise as well?
Two new studies came out recently suggesting that autism may be linked to pregnancy and delivery. One study found an association between low maternal levels of thyroxine, a thyroid hormone, and autism. Another found that women whose labors were induced or sped up were slightly more likely to have an autistic child. The study notes that it is not the induction itself that led to the autism, but rather an underlying problem with the pregnancy that prevented the normal progression of labor. The authors note that women should not be afraid of being induced as the risk of harm to a baby in distress is much greater than the modest risk of autism.
