Preventing Osteoporosis

Plant SterolsThe National Osteoporosis Foundation estimates that 50% of women and 25% of men, over the age of 50, will have an osteoporosis-related fracture during their lifetime.1 The best protection against osteoporosis is a combination of weight-bearing exercise and excellent nutrition.

Bone strength is directly related to muscle strength.
The most effective way to strengthen bone and protect against osteoporosis-related fractures is by increasing muscle strength.2 Weight-bearing exercises are ideal for improving balance and building bone strength.3 While swimming and biking are good for cardiovascular conditioning, they will not help protect against osteoporosis like running or lifting weights can.4 In women, who are at a risk for osteoporosis, back strengthening exercises are especially beneficial and can provide lasting protection against spinal fractures.5 For women, in addition to doing weight-bearing exercises, I also recommend wearing a weighted vest for a few hours each day for stronger bones. A weighted vest can be worn, not only during exercise, but also while you work or shop and bend, stand, and move throughout the day. Wearing a weighted vest has other benefits as well, such as burning more calories, increasing core strength and stabilizing muscles, thus improving balance and decreasing the risk of falls.6-9

Certain foods supply the body with the nutrients necessary to build and maintain healthy, strong bones. Other foods promote the breakdown of bone and osteoporosis.

The best foods for bone health are whole plant foods. Studies show that individuals with the highest consumption of fruit and vegetables have the strongest bones, and bone health-promoting effects of flavonoids, plum/prune polyphenols and additional phytochemicals are now being investigated.10-12

  • Greens, seeds, and beans are healthful calcium sources: A diet full of natural plant foods provides the calcium required to build strong bones. Green vegetables in particular are rich calcium sources. For example, one four-ounce serving of steamed kale has just as much calcium as one cup of milk. Broccoli, bok choy, sesame seeds, and garbanzo beans are also excellent calcium sources. Furthermore, the body absorbs about 50% of the calcium in green vegetables, compared to only 32% of the calcium in milk.12
  • Green vegetables for vitamin K: Vitamin K is a crucial component for maintaining healthy bones. Higher intake vitamin K1 is associated with bone health, and in supplementation trials using vitamin K2 (which is low in plant foods), fracture risk was greatly reduced.14,15 It is important to get both K1 from green vegetables and K2 from a supplement.
  • Nuts and seeds for magnesium: Nuts and seeds are rich in magnesium, an essential mineral, which is used for the formation of bone tissue.16
  • Beans, nuts, and seeds for plant protein: For most people following a Nutritarian diet, maintenance of bone mass, muscle mass and muscle strength with age can be achieved easily with a Nutritarian diet that includes seeds, nuts and beans. For healthy bones, it is important to ensure adequate protein intake in mid-life and especially after the age of 70.17 Although this is routinely accomplished with protein-rich plant foods, animal products may be added if muscle mass starts to fall too low on a completely vegan diet.
  • Beans, whole grains, nuts and seeds for phytate: Phytate is known as an “anti-nutrient,” a substance that prevents us from absorbing certain minerals, however the phytate in many plant foods might actually benefit bone health. Studies have found that women who consume more phytate had either greater bone mineral density or less bone mass loss.18-20 Phytate appears to help to prevent osteoporosis by preventing bone breakdown by bone-resorbing cells.21

The worst foods for bone health are foods that promote calcium loss:

  • Salt promotes the excretion of calcium in the urine.22,23
  • Caffeine also contributes to urinary calcium loss. High caffeine intake is associated with increased bone loss and osteoporotic fractures.24,25
  • Soda, including diet and decaffeinated soda, is associated with bone loss. Soda consumption increases parathyroid hormone (PTH) in the blood, which increases blood calcium concentrations by stimulating bone breakdown. This increased blood calcium is then excreted in the urine.26-28
In Osteoporosis Protection for Life, I have put together a comprehensive approach that combines dietary advice, supplements, and special bone-strengthening exercises, which can provide significant improvements, when compared to drug treatment, for osteopenia and osteoporosis. This DVD provides the information that is needed to put an effective osteoporosis prevention plan into place and take action. Just a few minutes a day, or fifteen minutes twice a week, is all that it takes to complete the exercises that can keep your bones strong—for life.
