Why do we need Calcium?

What You Must Know About Calcium Intake

  • Calcium deficiency causes osteoporosis, accelerates tooth decay, causes muscle tension, and often associated as one of the causes for high blood pressure.
  • To absorb the calcium that we eat, we need another essential nutrient- Vitamin D. Vitamin D is mainly sourced through Sun light, fatty wild fish like mackerel and tuna, egg white and not to forget, fortified foods and drinks.
  • Too much caffeine, alcohol and sodium affects the calcium absorption by body and may cause a deficit. Limiting these will lead to a better calcium availability on a daily basis.
  • Calcium consumption per day should be 100-1200 mg which can be stretched till 2500 mg as a maximum. For persons who are taking supplements of iron, magnesium, zinc or other trace elements should avoid taking any food that is high in calcium. This is since calcium absorption inhibits proper absorption of these metallic nutrients for a short while. Also, more calcium leads to constipation and occurrence of kidney stones.

Now that we know about why calcium is needed, let’s take a look at how to achieve the recommended amount of calcium intake every day. Here are the best foods that provide calcium.
