What you need to know about calcium

 

Calcium is an important mineral for people of all ages. Your body uses calcium to build healthy bones and teeth. If you don’t get enough, your bones can become weak and fragile over time. Calcium also helps your heart, muscles and nerves work properly.







What foods contain calcium?

Calcium can be found in a variety of foods including milk, yogurt, cheese, kefir, calcium-fortified soy beverage, canned fish, cooked spinach, legumes and almonds.

What helps me absorb calcium? 

Vitamin D helps your body absorb calcium and can be found in fatty fish (like sardines, salmon, tuna and mackerel), eggs, margarine, cow’s milk and other fortified milk alternatives such as soy, rice and almond beverages.


What lowers calcium absorption?

  • Caffeine: Aim for no more than 400mg of caffeine per day for adults (or approximately 2-3 cups of coffee per day). Pregnant and breastfeeding women should have no more than 300mg of caffeine per day.
  • Alcohol: Limit alcohol and have no more than 2-3 drinks per day.
  • Smoking: If you need help quitting, visit Health Canada’s On the Road to Quitting program.
  • Foods that contain oxalates such as spinach, sweet potatoes, rhubarb and beans can lower calcium absorption. However, you do not need to avoid these foods if you are meeting your calcium needs and following Canada’s Food Guide.
  • Medications: Ask your health care provider if any medications you take may affect calcium absorption.
