Your bones do much more than hold your body upright. They protect important organs such as your brain, heart, and lungs, store minerals like calcium, and work together with your muscles to help you move.
Although bones look hard and solid, they are living tissues that are constantly breaking down old bone and building new bone. This process continues throughout life, but it changes as we get older.
During childhood, the body builds bone faster than it removes it. Most people reach their greatest bone strength, known as peak bone mass, by their late twenties or early thirties. After that, bone breakdown slowly becomes faster than bone formation.
As a result, bones gradually become thinner and weaker. For some people, this leads to osteoporosis, a condition that greatly increases the risk of broken bones, especially in the hips, spine, and wrists.
The good news is that many everyday habits can help protect your bones and slow this natural loss. One of the most effective ways is regular physical activity. Bones become stronger when they are challenged. Weight-bearing exercises, where your feet support your body weight, encourage the body to make more bone tissue.
Walking, jogging, dancing, hiking, tennis, climbing stairs, and gardening are all helpful activities. Strength training with weights or resistance bands also improves bone strength by placing healthy stress on both muscles and bones.
Research published in the Journal of Bone and Mineral Research has shown that people who regularly perform weight-bearing exercise tend to have higher bone density than those who are inactive. Even moderate exercise performed consistently can make a meaningful difference over time.
Healthy eating is just as important. Calcium is the main mineral that gives bones their strength. About 99% of the body’s calcium is stored in the skeleton. If the diet does not provide enough calcium, the body removes calcium from bones to keep the heart, muscles, and nerves working properly.
Over many years, this can weaken the skeleton. Good sources of calcium include milk, yogurt, cheese, calcium-fortified plant milks, tofu made with calcium, almonds, and leafy green vegetables such as kale and bok choy.
Vitamin D is equally important because it helps the body absorb calcium from food. Without enough vitamin D, even a calcium-rich diet cannot fully protect your bones. Sunlight helps the skin produce vitamin D, although the amount varies depending on the season, skin type, and time spent outdoors.
Vitamin D is also found in oily fish such as salmon, sardines, and mackerel, egg yolks, and fortified foods. Some people, especially older adults, may need supplements after discussing this with their healthcare provider.
Several other nutrients also support healthy bones. Magnesium helps bones use calcium effectively and is found in nuts, seeds, beans, whole grains, and leafy vegetables.
Vitamin K supports proteins involved in building bone and is abundant in green vegetables. Research published in Nutrition Journal suggests that people with higher intakes of magnesium and vitamin K have a lower risk of fractures.
Protein is another nutrient that is sometimes overlooked. Bones are not made of minerals alone. They also contain collagen, a protein that gives bones flexibility and helps prevent them from breaking easily.
Eating enough protein from foods such as fish, eggs, dairy products, beans, lentils, soy foods, poultry, and lean meat helps maintain healthy bones and muscles, which also reduces the risk of falls.
Some lifestyle habits can damage bone health. Smoking slows the formation of new bone and reduces blood flow to bone tissue. Drinking excessive amounts of alcohol can interfere with the body’s ability to absorb calcium and vitamin D and may increase the risk of falls. Reducing or avoiding these habits can benefit both bone health and overall wellbeing.
Maintaining a healthy body weight is also important. People who are underweight often have lower bone mass and a greater risk of fractures. On the other hand, carrying too much weight may place extra stress on joints and make movement more difficult. Regular exercise and a balanced diet help people maintain a healthy weight while supporting strong bones.
Looking after your bones is a lifelong investment. Small daily habits, such as taking a brisk walk, eating calcium-rich foods, getting enough vitamin D, including enough protein in your meals, and staying physically active, can help preserve bone strength for many years.
These simple choices may reduce the risk of osteoporosis and fractures, helping you stay active, independent, and healthy as you grow older.
If you care about bone health, please read studies that plant-based diets can harm your bone health without these nutrients, and how to ease arthritis with anti-inflammatory foods.
For more health information, please see recent studies that too much of this vitamin may increase your risk of bone fractures, and results showing this type of exercise may protect your bone health, slow down bone aging.
