As the saying goes, “you are what you eat."
Daily calcium and vitamin D requirements increase with age. Use the table below to determine how much of these essential nutrients you need.*IU=international units
* Total diet plus supplement. Healthy adults between 19 and 50 years of age require 400 to 1000 IU daily. Those over 50 years or younger adults at high risk (those with osteoporosis, multiple fractures or conditions affecting vitamin D absorption) should receive 800 to 2000 IU daily. Taking more than 2000 IU of vitamin D daily should be done only under medical supervision.
CalciumAccording to Osteoporosis Canada, women older than 50 years of age require 1200 mg/day of calcium (supplement & dietary intake combined). Making sure you get enough calcium is an important step towards good bone health. By doing so, you’ll maintain an adequate supply so that your body doesn’t have to dip into the reserve of calcium in your bones.
It’s strongly recommended that you get the calcium you need from your diet whenever possible.
If you can’t get enough calcium from the foods you eat, you can also take a supplement.
What are some easy ways to work high-calcium foods or beverages into my diet?
Start the day with a cup of milk in your hot or cold cereal – just one cup of milk contains at least 300 mg of calcium.
Add a slice of cheese to a sandwich or having a canned salmon sandwich are both excellent lunchtime ideas that add another 200 to 500 mg of calcium.
For supper, a tofu stir-fry with a cup of green vegetables such as broccoli and kale can boost your calcium approximately 300 mg.

Vitamin D helps your body absorb calcium from the foods you eat. Your body naturally produces vitamin D when you’re exposed to sunlight; however, during the winter months, most Canadians do not get enough sun exposure to produce adequate amounts of vitamin D. The best way to enhance your vitamin D intake is through dietary sources and supplements.
What are some easy ways to work high-vitamin D foods or beverages into my diet?
Vitamin D fortified milk, yogurt and orange juice.
Several kinds of fish – such as salmon, sardines and swordfish – and some fish oils (halibut and cod liver oil).
Whole eggs (vitamin D is found in the yolk).

In addition to getting enough calcium and vitamin D, here are a few more things to keep in mind when planning your meals:Consume caffeine, alcohol and salt with moderation
Coffee, tea and soft drinks contain caffeine, which may decrease calcium absorption and contribute to bone loss – choose these drinks in moderation.
Avoid excessive alcohol intake – consume no more than 2-3 alcoholic drinks per day.
High-salt foods should be monitored – try to limit your sodium intake to no more than 2100 mg/day (about one teaspoon of salt).
Ask your doctor how much you need.
Get Into The Kitchen!
If you find yourself pressed for time, it may be tempting to opt for convenience foods instead of cooking from scratch. Unfortunately, processed foods tend to contain more of what you don’t need (for example salt, which can decrease your body’s ability to retain calcium) and not enough of what you do – vitamins, minerals and other nutrients in a fresh or close to fresh state.
Fortunately, there are ways to cook that don’t require an hour in the kitchen. With a bit of knowledge and advance preparation, you can take advantage of “healthy conveniences” like using frozen vegetables to ensure you eat healthy. You can even make use of your microwave!
