The website (lifehacker) says that there are alternatives to dairy products that contain large amounts of calcium, such as green leafy vegetables, nuts, seeds and canned fish.
He added that some foods are fortified with added calcium, such as soybeans, rice and oats.
The site advised to look at the nutrition information panel on food labels, to find out how much calcium they contain.
However, it is more difficult for the body to absorb calcium from foods compared to dairy products, which means that the body needs to eat more foods that contain calcium to improve bone health.
The human body’s need for calcium varies, depending on several factors, including age and gender, and the amount ranges between 360-1000 milligrams per day for adolescents and older women.
A 250ml cup of milk contains about 300 milligrams of calcium.
In the event that a person does not drink milk, he must replace it with other nutrients such as protein, which is found in meat and poultry, and potassium found in green vegetables.
