High Total Energy Diets Linked to Incontinence

Women who consume high-calorie diets or diets high in saturated fats have an increased risk for urinary incontinence, according to a new study published in the American Journal of Epidemiology.

Researchers examined intakes of total energy, carbohydrate, protein and fats in relation to urinary incontinence (UI) in a cross-sectional sample of 2,060 women in the population-based Boston Area Community Health Survey (2002–2005). Data were collected from in-person home interviews and food frequency questionnaires. Logistic regression was used to calculate odds ratios and 95 percent confidence intervals for the presence of moderate-to-severe UI; a severity index was analyzed in secondary analysis of 597 women with urine leakage.


Salt and Preservatives in Processed Meat May Increase Risk of Heart Disease and Diabetes

Eating processed meat like bacon and sausages could significantly increase risk of heart disease and diabetes, while unprocessed red meat may not be as harmful as once thought, according to a new Harvard study.

The researchers defined unprocessed red meat as any unprocessed meat from beef, lamb or pork, excluding poultry. Processed meat was defined as any meat preserved by smoking, curing or salting, or with the addition of chemical preservatives; examples include bacon, salami, sausages, hot dogs or processed deli or luncheon meats.

Lead author Renata Micha said the two types of meat contain similar levels of saturated fat and cholesterol but processed meats in the US contain on average 4 times more sodium and 50 per cent more nitrate preservatives than unprocessed meats.

Micha said: “This suggests that differences in salt and preservatives, rather than fats, might explain the higher risk of heart disease and diabetes seen with processed meats, but not with unprocessed red meats.”
