If you expect healthy foods to cost more, you're not alone (although this isn't always true).

Setting specific limits on sugar intake can alarm groups that profit from sugar use.

The conclusion was that sugar intake guidelines are based on low-quality evidence.

Hearing loss increases with age, affecting 40 to 66% of adults over age 65 and 80% of adults over age 85. Scientists are exploring whether iron deficiency contributes to the problem. Using clinical data from electronic medical records of 305,339 young to elderly adults, scientists examined the relationship between hearing loss and iron deficiency anemia.

In its 2017 update to the Standards of Medical Care in Diabetes, the American Diabetes Association included a new recommendation to assess the amount of fat and protein in meals, in addition to carbohydrate counting, to determine insulin dosing for people with type 1 diabetes on flexible insulin schedules.

About 1 in 6 Americans suffer a foodborne illness each year, often in their own homes, so safe food handling practices cant be overemphasized. Recently, scientists watched 100 episodes of cooking shows from 24 celebrity chefs preparing meat dishes and tracked the chefs food safety behaviors.

In a one-year weight loss trial based on dietary counseling, 175 obese adults with metabolic syndrome and at high risk for obstructive sleep apnea lost less weight and were 70% less likely to lose at least 5% of their weight, compared to those at low sleep apnea risk (assessed by a standard screening survey). Sleep apnea causes shallow breathing or breathing pauses during sleep.

Self-reported physical activity rates tend to decrease with age, especially in people with chronic disease, according to a recent CDC telephone survey of randomly-selected U.S. adults age 50 and older.

A decade or more before memory-related symptoms of Alzheimers disease (AD) appear, disordered processes are underway in the brain - including changes that may affect sense of smell.

Bags of lettuce and spinach may not be as pristine as they seem. British scientists found that during 5 days of refrigeration, traces of nutrient-rich juice released from crushed leaves in bags of salad greens nourished Salmonella bacteria and increased its growth by up to 280-fold compared to sterile water. The juices also enhanced the bacterias ability to attach to the sides of the plastic bags, as well as to the leaves, as reported in Applied and Environmental Microbiology.
