The Scotsman reports fad diets like Atkins and processed convenience foods are taking Scotland by storm. With more and more Scottish citizens adopting these diet-styles, health correspondent Lyndsay Moss says Scottish bones could be at risk.
A balanced diet including calcium, vitamin D and other minerals is vital for healthy bones, which are less at risk of fracture.
But the National Osteoporosis Society (NOS) warned that many Scots could be putting their bones at risk due to food fads and because they are eating more processed foods than before.
The charity said regimes such as the low-carbohydrate Atkins diet and the cabbage soup diet could mean people are not getting a nutritional balance.
Bone health is one of the less-discussed aspects of low-carbohydrate diets. A great place to find out more about it is at AtkinsExposed.org, which addresses bone health several times. Here are some highlights:
- "Some high-protein, very-low-carbohydrate, weight-loss diets are designed to induce ketosis. When carbohydrate intake or utilization is insufficient to provide glucose to the cells that rely on it as an energy source, ketone bodies are formed from fatty acids. An increase in circulating ketones can disturb the body's acid-base balance, causing metabolic acidosis. Evidence suggests that even mild acidosis can have potentially deleterious consequences over the long run, including low blood phosphate levels, resorption of calcium from bone, increased risk of osteoporosis, and an increased propensity to form kidney stones."

- "Urinary excretions of calcium and acids are correlated positively with intakes of animal and nondairy animal protein but are correlated negatively with plant-protein intake." Read more.
- "The concern with bone health arises from the fact that muscle protein has a high sulphur content. When people eat too much of this meat protein, sulfuric acid forms within our bodies which must somehow be neutralized to maintain proper internal pH balance. One way our bodies can buffer the sulphuric acid load caused by meat is with calcium borrowed from our bones." Read more.
- "Despite having some of the highest calcium intakes in the world, the Inuit also have some of the worst rates of osteoporosis." Read more.
