Boost your Bone Strength with Extra Virgin Olive Oil

dreamstime_s_17124055The beneficial effects of the Mediterranean Diet on cardiovascular health have long been recognize. In recent years, the diet has also been shown to support bone health, even reducing the risk of osteoporotic fractures!  A recent study published in Clinical Nutrition explored the effect of the Mediterranean Diet, in particular the consumption of different varieties of olive oil, on the risk of osteoporosis-related fractures. The study concluded that a Mediterranean diet with a high consumption of extra virgin olive oil (EVOO) was associated with a lower risk of osteoporosis-related fractures in the middle-aged and elderly Mediterranean population.  The consumption of other oils, including other common olive oils, was NOT associated with a lower risk of fractures in the study.  So what’s the difference between olive oils and what makes EVOO so beneficial?

The difference lies with how the oil is extracted and processed:
Extra virgin olive oil is made from the first cold pressing of the olives and pits and no heat or chemicals are used during this production process.
Virgin olive oil is the oil produced from the second cold pressing.
Pure olive oil is a blend of processed olive oil and a small percentage of EVOO.
Light or extra light olive oil is the lowest quality of olive oil and is manufactured by using chemicals and heat to remove impurities.  Sometimes it is blended with other oils such as canola oil.

Procuring the oil from the first pressing is essential because it contains the highest concentrations of phytonutrients and polyphenols which have well-known anti-inflammatory properties and may also play a role in the prevention of bone loss.  Oleuropein, a key phenolic component of EVOO, may prevent bone loss associated with osteoporosis by increasing formation of osteoblasts (bone forming cells).  Two other phenols, tyrosol and hydroxytyrosol, may increase bone formation while reducing inflammation that initiates bone breakdown.

Because the processing of the olive oil affects the polyphenol levels, consuming pure, authentic extra virgin olive oil is essential to acquiring all the bone building benefits.  Unfortunately, much of the olive oils in your local food stores have been found to be adulterated with cheap soybean or other inferior oils, mislabeled or even rancid.  In a 2010 study done by UC Davis , 79% of the EVOO tested were rancid, of poor quality or adulterated with cheaper, refined oils. ConsumerLab.com evaluated 10 EVVO products for quality as well as polyphenol content and found that only 7 of the 10 passed, with 3 being uncertain that they were even EVOO.  See the chart below for the EVOO testing and results.

What if you use a brand not tested by ConsumerLab.com, how do you know its quality or purity?  Unfortunately, it is impossible to judge the purity of EVOO just looking at it or tasting it.  However, there are things that you can look for to help you identify a quality oil.

Consumerlabs.com suggests evaluating your olive oil using the following guidelines:
1.  Look for a certification seal on the label: USDA Quality Monitoring Program, North American Olive Oil Association (NAOOA), California Olive Oil Council (COOC), the Extra Virgin Alliance (EVA).
2.  Choose an oil that includes a harvest date:  It is best to buy an oil within 15 months of its harvest date, not to be confused with the “Best By” date.  Unfortunately, not all labels provide a harvest date.
3.  Choose an oil packaged in dark glass: Dark glass protects the oil from oxygen and light.  Also, storing oil in a cabinet will protect it from light and keep it fresh longer.
Its important to note that cooking also affects olive oil.  It has been shown that temperature, cooking time and cooking method all modify the chemical structure of olive oil and deplete the polyphenols and vitamin E within a short period of time.

Recommendations when cooking with olive oil:
1.  Keep heating time to a minimum
2.  When possible, add olive oil in the later stages of cooking
3.  When cooking for longer period of time, add small amounts of olive oil frequently to replenish

To ensure you are getting all the valuable polyphenols to boost your bone health, add 3-4 tablespoons of cold EVOO to salads, pasta, fish or anything else. In addition to protecting against cardiovascular disease, using quality EVOO is another way you can build strong, healthy bones for life!

â„¢Here’s why leafy greens should be at the top of your dietary list for bone health: 

1. Calcium-Rich Goodness

While dairy products are known for their calcium content, green leafy vegetables can be just as potent. Calcium is a fundamental mineral for bone health, and leafy greens like kale, collard greens, and turnip greens provide an excellent plant-based source of this nutrient. One cup of cooked kale can offer as much calcium as a cup of milk, making it an essential addition to your diet.

 

2. Vitamin K: The Bone Protector

Leafy greens are rich in vitamin K, a nutrient vital for bone health. Vitamin K helps in the activation of osteocalcin, a protein that binds calcium to the bone matrix, strengthening bones. Additionally, vitamin K helps reduce excessive bone demineralization, protecting against bone loss and fractures. Spinach, kale, and Swiss chard are particularly high in vitamin K, making them superstars for your skeletal system.

 

3. Magnesium for Bone Metabolism

Magnesium is another crucial nutrient found abundantly in leafy greens. About 50-60% of the body’s magnesium is stored in the bones, where it plays a pivotal role in bone metabolism and mineralization. Magnesium also assists in converting vitamin D into its active form, which aids in calcium absorption. Incorporating greens like spinach and kale into your diet ensures you get enough magnesium for optimal bone health.

 

4. Maintaining Alkaline Balance

A diet rich in leafy greens helps maintain the body’s acid-base balance, which is essential for bone health. When the body becomes too acidic, it may leach calcium from the bones to neutralize the acid, leading to weakened bones. Leafy greens, being alkaline, help maintain a balanced pH, preventing calcium loss and keeping your bones strong and healthy.

 

5. Packed with Antioxidants and Other Nutrients

Green leafy vegetables are packed with a range of vitamins and minerals that contribute to overall health. Vitamin C, found in greens like kale and spinach, is necessary for collagen formation, which is a critical component of bone structure. Additionally, the antioxidants in leafy greens help protect bone cells from damage and reduce inflammation. The concept of osteoimmunology highlights the connection between the immune system and bone health. Nutrients found in leafy greens help modulate immune responses, reducing inflammation and promoting bone regeneration and repair.

 

6. Fiber for Digestive Health

Leafy greens are high in dietary fiber, which supports a healthy digestive tract and promotes regular bowel movements. Fiber also aids in maintaining a healthy gut microbiome, which is crucial for bone health. A healthy gut microbiome can enhance nutrient absorption, including calcium and magnesium, synthesize essential vitamins such as vitamin K2, reduce inflammation, and regulate hormones, all of which further support bone health.

 

 I recommend aiming to get 2-3 cups of leafy greens a day

 

Practical Ways to Add Leafy Greens to Your Diet

1. Smoothies: Add a handful of your favorite greens to your smoothie.

2. Salads: Make leafy greens the base of your salads. Mix varieties like arugula, romaine, kale, and spinach for a nutrient-packed meal.

3. Soups and Stews: Add chopped greens to soups, stews, and broths. They add flavor and a nutritional boost.

4. Stir-Fries: Incorporate greens like bok choy or Swiss chard into your stir-fries for a quick and healthy dinner.

5. Wraps and Sandwiches: Use large leafy greens as wraps or add them to sandwiches for extra crunch and nutrition. 

 

NOTE: While green leafy vegetables are incredibly beneficial for bone health and overall well-being, it is important to be mindful of their oxalate content. Oxalates, are naturally occurring compounds found in many plants, including leafy greens, nuts, seeds and certain vegetables. They can bind to minerals in the gut which can interfere with their absorption. For this reason, oxalates are considered anti-nutrients. I delve deeper into the topic of oxalates in my BONES Methodâ„¢ Program where I discuss what foods have the highest oxalate content, the best alternatives, and how to manage oxalate intake effectively. Supporting optimal bone health doesn’t require perfection—it requires balance. In this program you will discover how a well-rounded, nutritious diet can contribute to strong bones and overall wellness.

Incorporating green leafy vegetables into your daily diet is a simple and effective way to support your bone health. These greens provide a rich source of calcium, vitamin K, magnesium, fiber, and antioxidants, all of which are essential for maintaining strong and healthy bones. Additionally, their benefits extend to supporting digestive health and boosting immune function, making them a cornerstone of a bone-healthy diet. So next time you plan your meals, make sure to include a generous serving of leafy greens and give your bones the nourishment they need to stay strong for life.

 

 Eat like a horse, and enjoy the benefits of strong, healthy bones for years to come!
