Researchers found that consuming out-of-hand nuts led to higher intakes of healthy fats, fiber, and lower carbohydrate intake. This was associated with a reduced risk of hypertension and low HDL cholesterol levels in both children and adults.
A study analyzing data from 47 studies found that increasing height increases the risk of ovarian cancer by 3% per decade. For body mass index, risks vary depending on whether women have taken menopausal hormone therapy, with an attenuated relationship in never-users.
A recent study published in PLoS ONE found that the Body Mass Index (BMI) substantially under-diagnoses obesity in the US, with 39% of Americans classified as overweight being actually obese. The researchers suggest using leptin levels in conjunction with BMI to provide a more accurate measure of adiposity.
