More alkaline diet strengthens skeletal health
The ACC/AHA 2008 Task Force on Performance Measures’ Statement on Performance Measurement and Reperfusion Therapy will webpost on Monday, November 10 at 2 pm ET. The statement clarifies key issues in the measurement of reperfusion therapy for patients with ST-segment elevation myocardial infarction. The use of reperfusion therapy, drugs or procedures that restore blood flow

Diets that are high in protein and cereal grains produce an excess of acid in the body which may increase calcium excretion and weaken bones, according to a new study accepted for publication in The Endocrine Society’s Journal of Clinical Endocrinology & Metabolism (JCEM).
The study found that increasing the alkali content of the diet, with a pill or through a diet rich in fruits and vegetables has the opposite effect and strengthens skeletal health.
“Heredity, diet, and other lifestyle factors contribute to the problem of bone loss and fractures,” said Bess Dawson-Hughes, M.D., of Tufts University in Boston, Mass. and lead author of the study. “When it comes to dietary concerns regarding bone health, calcium and vitamin D have received the most attention, but there is increasing evidence that the acid/base balance of the diet is also important.”
Average older adults consume diets that, when metabolized, add acid to the body, said Dr. Dawson-Hughes. With aging, we become less able to excrete the acid. One way the body may counteract the acid from our diets is through bone resorption, a process by which bones are broken down to release minerals such as calcium, phosphates, and alkaline (basic) salts into the blood. Unfortunately, increased bone resorption leads to declines in bone mass and increases in fracture risk.
“When fruits and vegetables are metabolized they add bicarbonate, an alkaline compound, to the body,” said Dr. Dawson Hughes. “Our study found that bicarbonate had a favorable effect on bone resorption and calcium excretion. This suggests that increasing the alkali content of the diet may attenuate bone loss in healthy older adults.”
In this study, 171 men and women aged 50 and older were randomized to receive placebo or doses of either: potassium bicarbonate, sodium bicarbonate, or potassium chloride for three months. Researchers found that subjects taking bicarbonate had significant reductions in calcium excretion, signaling a decrease in bone resorption.
“In this study, we demonstrated that adding alkali in pill form reduced bone resorption and reduced the losses of calcium in the urine over a three month period,” said Dr. Dawson-Hughes. “This intervention warrants further investigation as a safe and well tolerated supplement to reduce bone loss and fracture risk in older men and women.”
When it comes to remodeling our bones-an ongoing process of break down and renewal that goes on throughout adulthood–researchers have new evidence that our guts play a surprisingly important role. The findings point toward novel methods for increasing bone mass in patients with diseases characterized by impaired bone formation, including postmenopausal osteoporosis, according to the

If you have trouble keeping weight off and you’re wondering why - the surprising answer may well be the cheeseburgers you ate - when you were a toddler. Surprising new research by University of Calgary, Faculty of Kinesiology researcher Dr. Raylene Reimer, published in an international journal, indicates a direct connection between an adult’s propensity

Researchers at the University of Toronto, Faculty of Medicine, Toronto, Canada, have discovered that adiponectin, a protein secreted from adipocytes, is a metabolic link that can explain, in part, the known positive relationship between obesity and both bone mineral density and reduced susceptibility to fractures. This study appears in the December issue of Experimental Biology

Adelaide researchers have made a world breakthrough in treating premature babies at risk of developmental disorders. A six-year study led by Dr Maria Makrides from the Women’s and Children’s Health Research Institute and Professor Bob Gibson from the University of Adelaide has demonstrated that high doses of fatty acids administered to pre-term infants via their

A new study from the psychology department at Tufts University shows that when dieters eliminate carbohydrates from their meals, they performed more poorly on memory-based tasks than when they reduce calories, but maintain carbohydrates. When carbohydrates were reintroduced, cognition skills returned to normal. “This study demonstrates that the food you eat can have an immediate
