Osteoporosis is a health condition that can sneak up on you, often showing no symptoms until a bone breaks. Dr. Rozalina McCoy, an endocrinologist at the University of Maryland School of Medicine, explained that osteoporosis is diagnosed via a DEXA scan, which measures bone density and fracture risk. While low bone density is a key indicator, bone quality also matters. Risk increases with age, especially for women over 50 and men over 70. According to research in Clinical Medicine, 50% of women and 20% of men over 50 will experience an osteoporosis-related fracture.
Dr. Yesika Garcia, an endocrinologist in Manhattan, noted that after menopause, estrogen levels drop, removing a protective effect on bone density. However, there are ways to lower risk, including a focus on one often-overlooked food: sardines.
Key Strategies to Reduce Osteoporosis Risk
Dr. Deborah E. Sellmeyer of Stanford Medicine emphasized that nutrition and weight-bearing activity are crucial. She recommends 30 minutes daily of impact activity like brisk walking, progressive weight and resistance training twice a week, and balance training such as tai chi or yoga. Avoiding falls is also vital: use good lighting, clear trip hazards, and keep up with eye exams.
Calcium and Vitamin D: The Bone-Building Duo
All four endocrinologists agreed that calcium and vitamin D are the only nutrients proven to reduce fracture risk. Dr. Jad Sfeir of the Mayo Clinic recommends 1,000–1,200 mg of calcium and 800–1,000 IU of vitamin D daily, preferably from food. Protein is also important for bone structure.
Sardines: A Nutrient Powerhouse
While a balanced diet is key, Garcia highlighted sardines because they contain both calcium and vitamin D. One 3-ounce serving provides 325 mg of calcium (30% of the daily goal) and 46 IU of vitamin D (17% of the goal). For maximum benefit, eat sardines two to three times a week. If sardines aren't your preference, dairy products like milk, yogurt, and cheese are excellent calcium sources. Vegans or lactose-intolerant individuals should monitor their levels with bloodwork and consult a doctor or dietitian.
Foods and Drinks to Avoid
Alcohol is the top offender, suppressing bone-building cells and interfering with vitamin D. Soda is second, due to phosphoric acid that leaches calcium from bones. Excess sodium also causes calcium loss through urine. As Garcia said, "Osteoporosis is common but not inevitable. It is largely preventable." Start supporting your bones early through diet and exercise—it's never too late to improve bone density.
