hope it helped you ☺️
The average adult’s weight is made up of about two per cent calcium. Most of this is found in the skeleton and teeth – the rest is stored in the tissues or blood. Calcium is vital for healthy teeth and bones. It also plays a crucial role in other systems of the body, such as the health and functioning of nerves and muscle tissue.
Good sources of calcium include dairy foods like milk, yoghurt and cheese, and calcium-fortified products, such as some plant-based milks (for example, soy milk and rice milk) and breakfast cereals.
People at different life stages need different amounts of calcium – young children, teenagers and older women all have greater than average requirements.
According to the most recent National Nutrition and Physical Activity Survey of 2011–12:
Over half of all Australians aged two years and over consume inadequate levels of calcium from food sources.
Females are less likely to have adequate intakes of calcium than males.
73 per cent of females consume less calcium than recommended.
51 per cent of males consume less calcium than recommended.
It is much better to get calcium from foods than from calcium supplements. Be guided by your doctor about whether you need additional supplements. Too much calcium from supplements may cause other health problems.
