Calcium is vital for healthy bones and teeth. It is also important for muscle and nerve activity in our body, including our heartbeat. A lack of calcium can lead to rickets in children or osteoporosis in older adults.
Who is calcium important for?
It is important for all of us to eat calcium-rich foods throughout our lives. Growing youngsters (especially teenagers), and older men and women need extra calcium.
Where can I get calcium from?
The best sources of calcium are low-fat milk and milk products as the calcium in milk is easily absorbed by the body.
Calcium is also found in other foods, including dark green leafy vegetables, almonds, sardines, salmon with bones, tofu.
Vitamin D helps to increase the absorption of calcium in food.
Calcium from food is best. Calcium supplements should only be taken if you have difficulty getting enough calcium from your diet. Talk to your healthcare provider about what is best for you.
Tips to increase your calcium intake
- Select reduced-fat varieties of dairy foods.
- Have small amounts of raw, unsalted almonds as a healthy snack.
- Make a green leafy salad with 45g tinned salmon as a quick lunch.
- Have a pottle of low-fat, low-sugar yoghurt for a calcium-filled afternoon tea.
- Drink a glass of milk with your breakfast or lunch.
- Try adding some of the calcium-rich foods from the table below to your meals.
What else do I need to know?
Physical activity, especially weight-bearing exercise, is also important for healthy bones.
Calcium supplementation remains an area of controversy, so it is recommended you discuss possible supplementation, and dosage, with your doctor.
