Prevention of Osteoporosis

Three factors essential for keeping your bones healthy throughout your life are:

  • Nutrition
  •  Protein
  • Fruit and veg
  • Adequate amounts of calcium
  • Adequate amounts of vitamin D
  • Other vitamins and minerals
    • B Vitamin & Homocysteine
    • Magnesium
    • Vitamin A
    • Vitamin K
    • Zinc
  • Regular exercise

Calcium

Men and women between the ages of 18 and 50 need 1,000 milligrams of calcium a day. This daily amount increases to 1,200 milligrams when women turn 50 and men turn 70. Good sources of calcium include:

  • Dark green leafy vegetables
  • Canned salmon or sardines with bones
  • Soy products, such as tofu
  • Calcium-fortified cereals and orange juice

If you find it difficult to get enough calcium from your diet, consider taking calcium supplements. But too much calcium has been linked to heart problems and kidney stones. The Institute of Medicine recommends that total calcium intake, from supplements and diet combined, should be no more than 2,000 milligrams daily for people older than 50.

Vitamin D

Vitamin D is necessary for your body to absorb calcium. Many people get adequate amounts of vitamin D from sunlight, but this may not be a good source if you live in high latitudes, if you’re housebound, or if you regularly use sunscreen or you avoid the sun entirely because of the risk of skin cancer.
Scientists don’t yet know the optimal daily dose of vitamin D. A good starting point for adults is 1000 international units (IU) a day, through food or supplements. If your blood levels of vitamin D are low, your doctor may suggest higher doses.

 

Nutrition and bone, muscle and joint health are closely related. A healthy diet can help you prevent and manage osteoporosis and related musculoskeletal disorders by assisting in the production and maintenance of bone. Conversely, if you’re not getting the right nutrients you’re putting yourself at greater risk for bone, muscle and joint disease.

So which nutrients should you be getting, and what’s the best way to get them?

Two of the most important nutrients are calcium and vitamin D. Calcium is a major building-block of bone tissue (the skeleton houses 99% of the body’s calcium stores). Vitamin D is key at it assists your body to absorb calcium – the two go hand in hand.

There are a number of foods, nutrients and vitamins, besides calcium and vitamin D, that help to prevent osteoporosis and contribute to bone, muscle and joint health, including protein, fruits and vegetables, and other vitamins and minerals.

 

Protein

Adequate dietary protein is essential for optimal bone mass gain during childhood and adolescence. It’s also responsible for preserving bone mass with ageing. Lack of protein robs the muscles of strength, which heightens the risk of falls, and contributes to poor recovery in patients who have had a fracture1.

Lean red meat, poultry and fish, as well as eggs and dairy foods, are excellent sources of animal protein. Vegetable sources of protein include legumes (e.g. lentils, kidney beans), soya products (e.g. tofu), grains, nuts and seeds.

Fruits and Vegetables

Fruits and vegetables contain an array of vitamins, minerals, antioxidants and alkaline salts – some or all of which can have a beneficial effect on bone. Studies have shown higher fruit and vegetable consumption is associated with beneficial effects on bone density in elderly men and women2,3.

Other vitamins and minerals

B Vitamins and Homocysteine

Some studies suggest high blood levels of the amino acid homocysteine may be linked to lower bone density and higher risk of hip fracture in the eldery. Vitamins B6 and B12, as well as folic acid, play a role in changing homocysteine into other amino acids for use by the body, so it is possible that they might play a protective role in osteoporosis. Research is ongoing as to whether supplementation with these B vitamins might reduce fracture risk.

Magnesium

Magnesium plays an important role in forming bone mineral. Magnesium deficiency is rare in well-nourished populations. The elderly are sometimes risk of mild magnesium deficiency, as magnesium absorption decreases with age. Particularly good sources of magnesium include green vegetables, legumes, nuts, seeds, unrefined grains and fish.

Vitamin A

The role of vitamin A in osteoporosis is controversial. Vitamin A is present as a compound called retinol in foods of animal origin, such as liver and other offal, fish liver oils, dairy foods and egg yolk. Some plant foods contain a precursor of vitamin A, for example in green leafy vegetables, and red and yellow coloured fruits and vegetables. Consumption of vitamin A in amounts well above the recommended daily intake may have adverse effects on bone.

Such high levels of vitamin A intake are probably only achieved through over-use of supplements, and intakes from food sources are not likely to pose a problem. Further research is needed into the role of vitamin A in bone health, although many countries at present caution against taking a fish liver oil supplement and a multivitamin supplement concurrently.

Vitamin K

Vitamin K is required for the correct mineralization of bone. Some evidence suggests low vitamin K levels lead to low bone density and increased risk of fracture in the elderly. Vitamin K sources include leafy green vegetables such as lettuce, spinach and cabbage, liver and some fermented cheeses and soya bean products10,11.

Zinc

This mineral is required for bone tissue renewal and mineralization. Severe deficiency is usually associated with calorie and protein malnutrition, and contributes to impaired bone growth in children. Milder degrees of zinc deficiency have been reported in the elderly and could potentially contribute to poor bone status. Sources of zinc include lean red meat, poultry, whole grain cereals, pulses and legumes12,13.

Exercise

Exercise can help you build strong bones and slow bone loss. Exercise will benefit your bones no matter when you start, but you’ll gain the most benefits if you start exercising regularly when you’re young and continue to exercise throughout your life.
Combine strength training exercises with weight-bearing exercises. Strength training helps strengthen muscles and bones in your arms and upper spine, and weight-bearing exercises — such as walking, jogging, running etc .
