For the few people who require more than 500 to 600 mg of calcium in supplement form, the dose should be split. For best absorption, calcium carbonate should be taken with meals. Calcium citrate may be taken anytime.

More Antioxidants in Loose Tea or Tea Bags?

Tea (from the Camellia sinensis plant) is a rich source of flavonoid phytonutrients, which function as antioxidants. The amount and relative proportion of these compounds in tea leaves depends on a variety of factors, including growing conditions, post-harvest processing (including the fermentation that converts green tea to oolong and black teas) and storage time before brewing. The form of tea, whether as loose leaf or the broken leaf (pekoe) and even smaller particles (fannings or dust) in bags, is not a clear determinant of its antioxidant capacity.

Is Bagged Salad as Safe as You Think?

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 bacteria’s ability to attach to the sides of the plastic bags, as well as to the leaves, as reported in Applied and Environmental Microbiology.

Sniffing Out Alzheimer’s Disease

A decade or more before memory-related symptoms of Alzheimer’s disease (AD) appear, disordered processes are underway in the brain - including changes that may affect sense of smell. In a study published in Annals of Neurology, researchers gave 183 community-living older adults cognitive tests to assess brain function, followed by tests of their ability to recognize and remember familiar odors, such as leather, menthol and grape.

Exercising with Chronic Disease

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.

Sleep Apnea May Slow Weight Loss

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.

Diabetes-friendly meals feature the same healthy foods - whole grains, colorful non-starchy vegetables, whole fruits, lean protein, fish, low-fat dairy, nuts and healthy fats - recommended for everyone.
