NUTRITION WEEK – CALCIUM AND VITAMIN D DEFICIENCY IN CHILDREN


How is Calcium and vitamin D related
  • Calcium and vitamin D work together to protect your bones—calcium helps build and maintain bones, while vitamin D helps your body effectively absorb calcium. So even if you're taking in enough calcium, it could be going to waste if you're deficient in vitamin D.
  • Vitamin D is essential in helping the body absorb and use calcium; in fact, the body cannot absorb calcium at all without some vitamin D. Vitamin D comes from two sources. It is made in the skin through direct exposure to sunlight, and it comes from the diet.
  • Vitamin D helps the intestines absorb calcium. However, vitamin D must first be activated or "turned on" by parathyroid hormone (PTH). Once activated, vitamin D acts to greatly increase the amount of calcium that the intestines can absorb from food, sometimes by as much as two to four times.
  • Lack of calcium in our diet forces the body to take calcium from bones to keep blood levels normal, which weakens bones
Vitamin D
  • Vitamin D helps your body absorb calcium. Calcium is one of the main building blocks of bone. Vitamin D also has a role in your nervous, muscle, and immune systems.
  • In children and adults, symptoms of vitamin D deficiency include bone pain or tenderness, dental deformities, impaired growth, increased bone fractures, muscle cramps, short stature, and skeletal deformities such as rickets. “Rickets is a medical condition tied to low vitamin D levels.
  • Severe vitamin D deficiency in children can cause a disease called rickets – a disorder that softens and weakens the bones and can occasionally lead to skeletal deformities.
  •  Vitamin D in three ways: through your skin, from your diet, and from supplements. Body forms vitamin D naturally after exposure to sunlight.
What causes vitamin D deficiency?
  • You can become deficient in vitamin D for different reasons:
ü  When you don't get enough vitamin D in your diet
ü  When vitamin D is not absorb enough from food (a malabsorption problem)
ü  When you don't get enough exposure to sunlight.
  • Who is at risk of vitamin D deficiency?
ü  Breastfed infants, because human milk is a poor source of vitamin D.
ü  Older adults, because your skin doesn't make vitamin D when exposed to sunlight as efficiently as when you were young, and your kidneys are less able to convert vitamin D to its active form.
ü  People with dark skin, which has less ability to produce vitamin D from the sun.
ü  People with disorders such as Crohn's disease or celiac disease who don't handle fat properly, because vitamin D needs fat to be absorbed.
ü  People who have obesity, because their body fat binds to some vitamin D and prevents it from getting into the blood.
ü  People who have had gastric bypass surgery
ü  People with osteoporosis
ü  People with chronic kidney or liver disease.
ü  People with hyperparathyroidism (too much of a hormone that controls the body's calcium level) 
  • How can I get more vitamin D?
There are a few foods that naturally have some vitamin D:
ü  Fatty fish such as salmon, tuna, and mackerel
ü  Cheese
ü  Mushrooms
ü  Egg yolks

ü  You can also get vitamin D from fortified foods. Foods that often have added vitamin D include
ü  Milk
ü  Breakfast cereals
