Calcium and vitamin D may not be the only protection against bone loss
New study finds diet rich in fruits and vegetables may strengthen bones
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."
New discoveries are revealing that dairy milk may be the biggest cause of illness in the world today. The Milk Imperative breaks new ground by revealing exactly how dairy milk causes osteoporosis and prostate cancer, backed up with the latest scientific studies. This book is sending shock waves through the dairy industry, and whether or not you consume dairy milk The Milk Imperative will change your life forever. Many non-dairy milk recipes also included.
Here are some of the secrets that milk suppliers don't tell you:
1. Low-fat milk is actually more fattening than regular whole milk! This is so for several reasons. For example, enzymes in regular milk get removed in low-fat milk: with no enzymes to 'eat up' the fat, more fat gets stored as surplus body fat. The Milk Imperative explains exactly why low-fat milk is not only more fattening, but much worse for health than regular milk.
2. Virtually all the latest research is saying that dairy milk is the single biggest cause of prostate cancer in men. This is no exaggeration. Here is an extract from one of the many similar studies quoted in The Milk Imperative:
" A summary of studies of prostate cancer shows a repeated association between consumption of dairy products and an elevated risk of developing prostate cancer. For example, in one study consuming two glasses of milk per day was associated with a 50% greater risk." Report from the 'Harvard School Of Public Health Nutrition Roundtable', Section 3: 'Calcium: Too Much of a Good Thing?'
3. Dairy milk is bad for motherhood. Did you know that dairy milk can harm a baby even before it is born? Milk contains a cocktail of harmful hormones, allergens, antibiotics, bad fats, rancid cholesterol, toxins, cow blood, bacteria, viruses, PCB's, dioxins, heavy metals, and more. Some of these harmful substances get passed into the delicate body of the unborn child, and later cause ill-health and impaired development as he/she grows up. For the mother, after giving birth dairy milk creates hormonal changes that prevent her from losing weight and regaining a slim figure.
We've all heard about lactose intolerance and milk allergies, but this is just the tip of the iceberg: dairy milk causes more disease than just about anything else by promoting harmful calcification. As fully revealed in The Milk Imperative, new discoveries are revealing for the first time that harmful calcification (and microcalfication) is at the root of most human illness, from cancer to heart disease. Even more shocking is to discover that the calcium and phosphorus in dairy milk play a major role in causing harmful calcification.
Advertisements Saying Dairy Products Help You Lose Weight Are Misleading
There have been recent claims that dairy products can help people lose weight, and the dairy industry has hyped the assertion by investing millions of dollars in commercial advertising. However, a new review of the evidence published in the journal Nutrition Reviews reveals that neither dairy nor calcium intake promotes weight loss. Amy Joy Lanou of the University of North Carolina at Asheville and Neal Barnard with the Physicians Committee for Responsible Medicine in Washington, DC, evaluated evidence from 49 clinical trials from 1966 to 2007 that assessed the effect of milk, dairy products, or calcium intake on body weight and BMI, with or without the use of dieting.
Evidence from the trials showed that neither dairy products nor calcium supplements helped people lose weight. Of the 49 clinical trials, 41 showed no effect, two demonstrated weight gain, one showed a lower rate of weight gain, and only five showed weight loss. An association between calcium or dairy intake and weight loss seen in some observational studies may be attributable to other factors, such as exercise, decreased soda intake, lifestyle habits, or increased fiber, fruit, and vegetable intake.
“Our findings demonstrate that increasing dairy product intake does not consistently result in weight or fat loss and may actually have the opposite effect,” the authors conclude.
This study is published in the May 2008 issue of Nutrition Reviews.
University of Adelaide scientists are part of an international research team that has uncovered the first example of a bacterium causing disease in humans by targeting a molecule that is incorporated into our bodies from our diet. The discovery was published today in the prestigious international journal Nature. Microbiologists Dr Adrienne Paton and Professor James Paton, and their collaborators, have shown that a potent bacterial toxin, Subtilase cytotoxin, specifically targets human cells that express a sugar called Neu5Gc on their surface. "Remarkably, humans cannot make Neu5Gc, and so we should all be resistant to the toxin," Professor Paton says. "However, consuming foods that have high levels of Neu5Gc, such as red meat and dairy products, leads to uptake of the sugar by human cells and this makes them susceptible to attack by the toxin." Subtilase cytotoxin is produced by E. coli bacteria that cause bloody diarrhoea and haemolytic uraemic syndrome (HUS) in humans. Professor Paton says in HUS, toxin-induced damage to the delicate cells lining the blood vessels causes clots, damage to red blood cells and kidney failure. Humans usually become infected with the potentially deadly E. coli after eating contaminated food, as occurred during Adelaide's Garibaldi outbreak in 1995. "Red meat and dairy products, the richest dietary sources of Neu5Gc, are also the foods that are most commonly contaminated with the E. coli bacteria that produce the toxin," Professor Paton says.
