We are continually being told that our collective waist lines are getting bigger, in fact, 66% of the adult population in the US are now either overweight or obese, defined by a Body Max Index (BMI) of 25 or greater. But what about the consequences of being underweight? Although only 5% of the population is considered underweight, defined by a BMI of less than 18.5, being underweight could in the event of serious illness, increase you chance of dying.
Hollow bones
Most think that obese people are at greater risk of lifestyle disease and illness but the underweight suffer from a plethora of conditions that place them at similar risk.
Because of inadequate calcium intake, one condition that the underweight are at risk of suffering from is Osteoporosis.
Most adolescents achieve peak bone mass by the twenties, dense bones reduce the effects of age related bone loss a serious condition and indirect cause of hospitalisation and mortality. Inadequate calcium intake during the growing years results in less than optimal bone density.
Without calcium you would be a jelly fish
Calcium plays an important role in a number of bodily activities and 99% of all calcium is stored in bones and teeth. Calcium is used for muscle contraction and relaxation, nerve function, blood clotting, nerve impulse and blood pressure. So, that next glass of milk is doing a lot more than just quenching your thirst, it may be saving your skeleton.
Stocking up on bone mass
Load bearing exercise and adequate intake of calcium is the best assurance that You won’t shatter when you reach your forties or fifties.
Men suffer from osteoporosis as well, although its much more prevalent amongst women due to the effects of menopause and hormone down regulation. Weight bearing exercise preferably weight training has been found to increase bone density by up to 1%, weight training also reduces the incidents of falls (a major cause of hip fractures and deaths)
Eating for a healthy skeleton
Adults calcium: 1000 mg /per day (19 to 50 yr)
Adults calcium: 1200 mg/per day (> 51 yr)
Phosphorus: 700 mg per day
Magnesium: Men 400 mg women 310 mg
Significant sources of calcium
Milk and dairy products, small fish with bones (salmon), bok choy, broccoli, chard, kale and legumes.
Start boning up
One of the best things we can do for our bones is to eat plenty calcium rich foods, exercise regularly and if you are one of the 5% that is underweight, eat more! Because the human skeletal system is more than something to hang your clothes on.
