Protect Your Bones: Key Nutrients and Bone Boosting Recipes

World Osteoporosis Day takes place every year on October 20.

The campaign, organised by the International Osteoporosis Foundation (IOF), aims to raise global awareness of the prevention, diagnosis and treatment of osteoporosis and metabolic bone disease.

Our bones are constantly being broken down and rebuilt in a process known as ‘bone turnover’. In our early years, bone is being built faster than it is being broken down, and we reach our 'peak bone mass' at some point during our 20s. After this time, preserving healthy bones becomes a vital health concern. If bone is broken down more quickly than it is remade, then osteoporosis can result.

This condition is of particular concern to postmenopausal women who produce less of the bone-protecting hormone oestrogen. Women lose more bone during their menopausal years than at any other time in their life. However, men are underdiagnosed with this disease and are more likely to go untreated.

The Key Three: Calcium, Magnesium and Vitamin D Calcium is widely understood to play a key role in bone health. After all, 99% of the body's calcium is stored in bone. However, a calcium-rich diet in the absence of other bone-building nutrients is not effective in building healthy bones. Good quality studies have even linked high calcium intake with increased risk of bone fracture. This is most likely because calcium must work alongside other nutrients to build and maintain healthy bones.

Calcium must be absorbed and retained effectively to benefit bones. This requires two more nutritional helpers: magnesium and vitamin D. These three nutrients work synergistically - none is effective without the others.

60% of the magnesium in our body is stored in our bones. Magnesium works hand in hand with calcium by stimulating the hormone calcitonin which helps to draw calcium into bone and keep it there. Magnesium is also required in order to convert vitamin D to its active form.

Unfortunately many of us fail to meet the recommended daily intake of magnesium. Deficiency in this mineral is a particular concern for girls. In a recent national survey, more than 50% of girls between the ages of 11 and 18 had inadequate magnesium intake, putting them at risk of osteoporosis in later years.

Vitamin D is also essential for calcium absorption, helping to transport calcium out of the intestine and into the bloodstream. An estimated 60-70% of the UK population are low in Vitamin D. Elderly people and darker skinned populations are at particular risk. It is difficult to obtain sufficient vitamin D from diet alone.

Supplements or sun exposure (around 15 minutes each day) are the best ways to obtain the daily requirement of this vitamin to support healthy bones.

Nutrients for bone retention Building healthy bone is only one part of the picture. Once healthy bone has been built, it is important to ensure that it is retained. Preventing bone from being broken down is essential in warding off osteoporosis. Special compounds in plant foods play a key role in preventing bone from being broken down. These compounds have 'bone resorption inhibiting properties'. They support bone health by 'turning off' osteoclasts, the cells that break down bone tissue.

Dried plums, a source of phenols, have been shown in human studies to improve bone density by preventing bone breakdown.

Other phytonutrients such as quercetin and hesperidin, present in fruits and vegetables such as onions, broccoli and citrus fruits, show similar benefits. Including these fruits and vegetables regularly alongside sources of calcium, magnesium and vitamin D is the key to nourishing strong and healthy bones.

Bone Boosting Recipes (Adapted from this original recipe)

Dried Plum ‘Bone Booster’ Snack Bars Prep Time: 10 minutes Cook Time: 30 minutes Serves: 8 Special phenolic compounds in dried plums increase levels of a hormone linked to bone formation. These compounds also help to prevent bone from being broken down. Dried plums, or prunes, are also high in antioxidants and provide essential nutrients for bone health such as potassium, boron and copper. Soy flour provides a source of ‘bone boosting’ phytoestrogens, while almonds, pumpkin seeds and sunflower seeds are useful sources of calcium and magnesium.

Ingredients

Olive oil cooking spray ¼ cup Dried Plum (Prune) purée ¼ cup honey ¼ cup orange juice 1 egg white 2 tsp grated orange zest ¼ cup soy flour ½ tsp cinnamon ½ teaspoon baking powder ½ cup rolled oats ½ cup whole almonds ½ cup unsweetened shredded coconut ¼ cup raw pumpkin seeds ¼ cup raw sunflower seeds

Directions Heat oven to 325ºF. Spray an 8x8” baking pan with cooking spray and line with parchment paper, leaving the paper overhanging on 2 sides. In a large mixing bowl, whisk together dried plum purée, honey, orange juice, egg white and orange zest. In small bowl, whisk together flour, cinnamon and baking powder. Fold flour mixture, oats, almonds, coconut, pumpkin seeds and sunflower seeds into dried plum mixture. Press mixture evenly into prepared pan. Bake about 30 minutes or until firm to the touch. Cool on rack; remove from pan, using paper to lift it out. Cut in four, then cut across in half to make 8 bars.

‘Better Bones’ Banana Oat Bars Makes one 9x9-inch pan.6 Servings.

Oats and flaxseed provide lignans which support bone and hormonal health after menopause.

Bananas provide potassium which helps to prevent loss of calcium from the body.

Anti-inflammatory omega 3, in the ground flaxseed and walnuts, is linked with improved bone density.

Special phenolic compounds in dried plums increase levels of a hormone linked to bone formation. These compounds also help to prevent bone from being broken down.

Dried plums, or prunes, are also high in antioxidants and provide essential nutrients for bone health such as potassium, boron and copper.

2 large, very ripe bananas 1 teaspoon vanilla (optional) 2 cups rolled oats 1/4 cup pitted, chopped prunes 1/4 cup chopped walnuts 2 tbsp ground flaxseed Grated nutmeg or cinnamon (optional)

Heat the oven to 350°F and lightly grease a 9x9-inch square baking dish with olive oil.

Peel the bananas and mash their flesh in a medium mixing bowl until no large chunks remain. Stir in the vanilla, if using. Add the oats and stir them in. Stir in the prunes and nuts.

Pat the thick mixture evenly into the baking pan. Sprinkle the top lightly with cinnamon. Bake for 30 minutes or until the edges just begin to crisp up.
