Middle-aged and elderly women constitute a high-risk group for osteoporosis, with a prevalence rate of approximately 20% among women over 50. Postmenopausal women experience reduced estrogen levels, leading to postmenopausal osteoporosis. It is common to observe women with hunched backs, often caused by spinal compression fractures resulting from osteoporosis.
How to prevent osteoporosis?
Ages 50–60
Generally, osteoporosis falls into two categories: postmenopausal osteoporosis and senile osteoporosis. Postmenopausal osteoporosis typically emerges around age 50 after menopause, while senile osteoporosis generally appears after age 62 in women and 72 in men.
During the initial 3–5 years after menopause, consistent long-term preventive calcium supplementation is essential, with daily intake of 1200–1500 mg. Milk is the optimal dietary source of calcium.Other calcium-rich foods include kelp, dark green vegetables, beans, dried shrimp, sesame seeds, and almonds. Beyond calcium supplementation, note that bone matrix forms the foundation of bone structure. Its primary components are proteins, amino acids, and minerals. Long-term vegetarian diets lacking sufficient protein can also lead to osteoporosis.
After Age 60
The most severe and common consequence of osteoporosis is fracture. For those already diagnosed with osteoporosis, the primary method to prevent osteoporotic fractures is fall prevention, followed by maintaining bone mass and strengthening bone density.The most common fracture sites in the elderly are the spine, wrist bones, and hip bones. Once a fracture occurs, bed rest for one month can result in a 10% loss of bone mass. Simultaneously, muscle atrophy begins, and mobility declines. This is particularly devastating for the elderly, who often have limited remaining bone mass to begin with.
How should osteoporosis be treated?
One approach is foundational therapy: including calcium and vitamin D supplementation. The other is pharmacological treatment: effective medications can increase bone density, improve bone strength, and thereby reduce fracture risk. These drugs fall into two categories: first, bone resorption inhibitors, with bisphosphonates being the primary choice; second, bone formation promoters.These medications must be used under medical supervision, typically for at least one year. They can alleviate osteoporosis symptoms and demonstrate good efficacy in preventing fractures.
What foods are beneficial for osteoporosis?
1. Vitamin K
Proteins essential for bone formation, such as osteocalcin and other proteins, require vitamin K to function properly.Individuals with low vitamin K levels face a 30% higher risk of hip fractures during running. Recommended daily intake is 90 micrograms for women and 120 micrograms for men.
Beneficial foods: Broccoli, spinach, kale, celery, and other leafy greens.
Proteins essential for bone formation, such as osteocalcin and other proteins, require vitamin K to function properly. Spinach is rich in vitamin K.
2. Magnesium
Women with osteoporosis often suffer from severe magnesium deficiency. Although magnesium accounts for only 1% of all minerals in bones, deficiency makes bones brittle and more prone to fractures.A daily intake of 400 milligrams is sufficient for most people. Additional supplementation can be beneficial as it helps prevent constipation often associated with calcium supplementation.
Beneficial foods: Whole grains, brown rice, almonds, peanuts, and spinach.
3. Protein
Though bones may seem inactive, they are constantly engaged in a dynamic process of breakdown and rebuilding.Protein is a crucial nutrient for bone synthesis. In fact, 22% of bone composition is protein. Approximately 1 gram of protein per kilogram of body weight is needed, but excessive intake should be avoided. Otherwise, it may acidify the blood, depleting calcium from bones and causing further damage.
Protein is a key nutrient for bone formation, and tofu is a protein source.
4. Vitamin B12
A 2008 study indicated that individuals with insufficient vitamin B12 intake experience greater bone loss. Vitamin B12 regulates homocysteine levels in the blood, a metabolite linked to heart disease and hip fractures.Healthy adults require 2.4 micrograms of vitamin B12 daily.
Beneficial foods: Shellfish, lean beef, and low-fat dairy products. Individuals over 50 should consider supplements, as vitamin B12 absorption becomes less efficient with age.
