Nutrition for Healing Broken Bones More Quickly

Nutrition for Healing Broken Bones More Quickly

Nutrition affects all aspects of your health, keeping your brain healthy and your bones strong. It is essential to give your bones the nutrients they need to maintain bone density and speed up the bone healing process.

Bones serve as a repository for calcium and phosphorus, produce bone marrow, and serve as anchors and supports for muscle contraction. Bones are both strong and flexible. After a bone fracture, your bone needs to repair the fracture and strengthen damaged bone. Consuming foods rich in key nutrients can help broken bones heal faster. Choose whole foods, healthy sources of fat, protein, and complex carbohydrates to support your bones and overall health.

Hormones control the balance of calcium and phosphorus in bone, and mechanical stresses on bone impact its density. Consuming healthy foods and engaging in regular weight-bearing exercise keep your muscles and bones ready for top performance. By managing your body composition, you can help avoid unwanted damage to bones and joints.

Protein

Protein makes up about half of bone volume and one-third of its mass. It provides a matrix for calcium-phosphate crystals to settle within.1 While calcium and other mineral salts give bone strength, protein is used to make collagen, which gives bone flexibility. Low protein intake is associated with decreased bone density and potentially increased fracture risk.2 The effect of dietary protein on bone appears to be favorable, but scientific evidence is lacking.1

Dietary sources rich in protein include the following:

  • Yogurt
  • Eggs
  • Beans
  • Legumes
  • Corn
  • Salmon
  • Beef
  • Oats
  • Almonds
  • Chicken
  • Cottage cheese
  • Milk
    Lentils
  • Fish
  • Quinoa

Iron

Iron is essential for red blood cell development. Too much or too little iron can upset the delicate balance between bone production and destruction. Bone is like a calcium bank. Deposits are made after you consume dietary calcium or a supplement. Withdrawals are made as body organs need calcium. Bones are completely reformed about every ten years. Areas of bone under increased stress build up bone, and bone that is not stressed breaks down. This is why exercise is also important for maintaining healthy bones.

Iron overload can cause3

  • Decreased bone mass
  • Osteoporosis
  • Osteopenia
  • Altered bone structure
  • Altered bone mechanics
  • Increased fracture risk

Iron is essential for delivering oxygen to bone and is involved in collagen production and vitamin D metabolism. Iron deficiency is thought to adversely affect bone, but the mechanism is unclear.4

The RDA for iron is based on age:

AgeIron requirement
0 to 6 months0.27 mg
7- 12 months11 mg
1-3 years7 mg
4-8 years10 mg
9-13 years8 mg
14-18 years11 mg male, 15 mg female, nonpregnant, not lactating
19-50 years8 mg
51 and older8 mg

Excellent sources rich in dietary iron include:

  • Fortified breakfast cereals
  • Oysters
  • White beans
  • Beef liver
  • Lentils
  • Spinach
  • Artichokes
  • Beef
  • Mackerel
  • Tuna
  • Shellfish

Calcium

Calcium is the principal mineral in bones. It provides bone strength and structure. Bones store more than 98% of the calcium in your body.5 Your body withdraws calcium from your bones throughout the day to supply the needs of other body organs. Calcium is essential for muscle contraction, blood clotting, hormone release, and sending messages throughout the nervous system. Bone is continuously remodeled in response to the stresses your muscles put on it.

Calcium cannot be produced by the body and must be consumed in the diet.

The U.S. RDA for calcium varies throughout your lifetime:

AgeUS RDA calcium
0-6 months200 mg
7-12 months260 mg
1-3 years700 mg
4-8 years1,000 mg
9-18 years1,300 mg
19-50 years1,000 mg (nonpregnant or lactating)
41-70 years1,000 mg male, 1,200 female
70 plus years1,200 mg

Calcium absorption decreases with age, and there is an inverse relationship between the amount of calcium in food and the percentage absorbed. For example, if you consume 200 mg of calcium daily, about 45% is absorbed. If your intake increases to 2,000 mg per day, the percentage absorbed drops to 15%.6 Supplying your body with calcium can significantly reduce bone loss.7

Dietary sources rich in calcium include:

  • Milk
  • Yogurt
  • Cheese
  • Tofu
  • Green leafy vegetables
  • Broccoli
  • Intact sardines and salmon with bones
  • Almonds
  • Legumes
  • Soybeans
foods with calcium

Vitamin C

Vitamin C (ascorbic acid) is essential for building collagen, the protein that gives bone flexibility. Collagen forms a matrix in bone, and the calcium salts sit in this matrix. Severe vitamin C deficiency causes scurvy, which results in weakened bones, poor wound healing, and impaired immunity. After completing a systematic review of the scientific literature, researchers concluded that vitamin C improves bone healing and bone formation, though they were unable to recommend a specific vitamin C dose.8

The RDA for vitamin C is:

AgeVitamin C
0-6 months40 mg
7-12 months50 mg
1-3 years15 mg
4-8 years25 mg
9-13 years45 mg
14-18 years75 mg males, 65 mg females
19 and older90 mg males, 75 mg females

Your body cannot produce vitamin C, so it must be consumed in the diet or as a supplement. Foods rich in vitamin C include the following:

  • Oranges
  • Grapefruits
  • Peppers
  • Broccoli
  • Strawberries
  • Potato
  • Spinach

Vitamin D

Calcium cannot be absorbed from the small intestine without vitamin D. Vitamin D comes in two forms: D2 and D3. Vitamin D2 is known as ergocalciferol, and it is found in plants and mushrooms. Vitamin D3, known as cholecalciferol, is commonly found in meats, fatty fish, and egg yolks. Vitamin D, whether from food, supplements, or exposure to ultraviolet light, must be activated in the body before it is useful.

Vitamin D promotes calcium absorption from the gut and helps maintain healthy calcium and phosphate levels in the bones and throughout the body. It also reduces inflammation, modulates the immune response, and plays a role in glucose metabolism and cell growth.

The U.S. RDA for vitamin D varies throughout your lifetime.9

AgeVitamin D
0-12 months400 IU
1-70 years600 IU   nonpregnant, not lactating
Over age 70800 IU

Few foods naturally contain vitamin D, but these have some:

  • Rainbow trout
  • Salmon
  • Tuna
  • Mackerel
  • Fish liver oils
  • Beef liver
  • Egg yolks
  • Cheese
  • Some mushrooms
  • Fortified milk and dairy
foods with vitamin D

Vitamin K

Vitamin K is essential for blood clotting, but it is also important for bone health. Vitamin K and vitamin D have a synergistic role in maintaining bone density and reducing fracture risk. Preliminary results from a human intervention study suggested that a combination of vitamin K and vitamin D improved bone density.10,11

The adequate intakes (AIs) for vitamin K vary by age:

AgeVitamin K
0-6 months2.0 mcg
7-12 months2.5 mcg
1-3 years30 mcg
4-8 years55 mcg
9-13 years60 mcg
14-18 years75 mcg
19 and older120 mcg males, 90 mcg female

Dietary sources rich in vitamin K include the following:

  • Collards
  • Turnip greens
  • Spinach]
  • Kale
  • Broccoli
  • Soybeans
  • Cauliflower
  • Cabbage

B Vitamins

Vitamin B12 deficiency is associated with decreased bone density. However, the mechanism is not well understood. Decreased vitamin B12 may be linked to decreased growth hormone and insulin growth factor 1.12

The US RDA for vitamin B12 varies by age.

AgeVitamin B12
0-6 month0.4 mcg
7-12 months0.5 mcg
1-3 years0.9 mcg
4-8 years1.2 mcg
9-13 years1.8 mcg
14-18 years2.4 mcg
19 years2.4 mcg

Dietary sources high in vitamin B12 include the following:

  • Beef liver
  • Clams
  • Tuna
  • Nutritional yeast
  • Salmon
  • Beef
  • Milk
  • Yogurt
  • Cheese
  • Egg

Potassium

Dietary potassium may neutralize acids in your body and reduce calcium loss from the bone. In one study, men aged fifty and older and postmenopausal women who consumed the most potassium in their diet had the highest bone density.13

The US RDA for potassium varies by age.

AgePotassium
0-6 months400 mg
7-12 months860 mg
1-3 years2,000 mg
4-8 years2,300 mg
9-13 years2,500 mg male, 2,300 mg female
14-18 years3,000 mg male, 2,300 mg female nonpregnant, not lactating
19-50 years3,400 mg male, 2,3600 mg female nonpregnant, not lactating
51 years and older3,400 mg male, 2,600 mg female

Dietary sources high in potassium include the following:

  • Apricots
  • Lentils
  • Squash
  • Prunes
  • Raisins
  • Potato
  • Kidney beans
  • Orange juice
magnesium rich foods

Magnesium

Like potassium, magnesium can also neutralize acids, protecting bone density. Magnesium helps with over 300 chemical reactions throughout the body. Magnesium deficiency reduces bone density and interferes with vitamin D production. Magnesium helps activate vitamin D, and vitamin D increases magnesium absorption.14

The U.S. RDA for magnesium is based on age:

AgeMagnesium
0-6 months30 mg
7-12 months75 mg
1-3 years80 mg
4-8 years130 mg
9-13 years240 mg
14-18 years410 mg male, 360 mg female nonpregnant, not lactating
19-30 years400 mg male, 310  mg female nonpregnant, not lactating
31- 50 years420 mg male, 320 mg female nonpregnant, not lactating
51 years and older420 mg male, 320 mg female

Foods rich in magnesium include:

  • Pumpkin seeds
  • Chia seeds
  • Almonds
  • Spinach
  • Cashews
  • Cereal
  • Black beans
  • Edamame

Supplements

Because of dietary restrictions and personal preferences, not everyone consumes the recommended daily allowance of these nutrients. Supplements can help fill the gap.

vitamin supplements

What Not to Eat

The foods to avoid when you have a broken bone are processed, calorie-dense, and nutrient-poor.

It’s also a good idea to avoid15-19

  • Salty foods: Salt increases calcium excretion in urine.
  • Soda: While the mechanism is not completely understood, increased soda consumption might increase bone fracture risk.
  • Caffeine: Caffeine can decrease calcium absorption and increase bone loss, but study results have been inconsistent.
  • Alcohol: Excessive chronic alcohol consumption decreases bone mass and density.
