Bone is a living, growing tissue. It’s made up of collagen, a protein that forms a soft framework for bone, and a mineral component called hydroxyapatite, made primarily of calcium and phosphorus which are deposited in this framework to give bones strength and hardness. In addition to protein, calcium and phosphorus, there are other nutrients that help support bone health. Here are some key bone-building nutrients and where to find them.
Calcium makes up about 2% of your total body weight, and most of it is stored in your skeleton.
Where to find it: Milk and milk products (yogurt, cottage cheese, etc.), almonds, green leafy vegetables.
Phosphorus is the second most abundant mineral in the body, and it combines with calcium to form the crystalline structure of bone.
Where to find it: Phosphorus is in many different foods, and most people get plenty in the diet. Major sources include milk, fish, poultry, meat, beans, nuts, seeds and whole grains.
Vitamin D helps the body absorb calcium from the digestive tract.
Where to find it: Fatty fish, liver, some fortified foods. Many people don’t consume enough vitamin D, however, and may benefit from taking supplements.
Magnesium stimulates the production of the hormone calcitonin, which helps to move calcium from the bloodstream into the bones. It’s also needed to convert vitamin D into its active form, which, in turn, supports calcium absorption.
Where to find it: Green leafy vegetables, beans, nuts, seeds and whole grains.
Potassium helps to maintain calcium balance in the body, and it helps to reduce the loss of calcium in urine.
Where to find it: Melons, tomatoes, bananas, peaches, oranges, leafy greens, sweet potatoes, beans.
Vitamin C is necessary for the formation of collagen, the protein matrix of bone tissue.
Where to find it: Citrus fruits, broccoli, tomatoes, strawberries, kiwifruit, peppers, green leafy veggies.
Boron is a mineral that supports the body’s use of other bone-building nutrients, including magnesium, phosphorus and vitamin D.
Where to find it: Dried fruits like prunes, raisins and apricots, also peanut butter and avocados.
