After age 70, bone loss accelerates to 1-2% per year, making fractures increasingly likely with every passing decade. But bone is living tissue that responds to nutrition, exercise, and targeted supplementation throughout your entire life. The right approach won't just slow bone loss — emerging research shows it can actually increase bone density even in your 70s and beyond.
## Understanding Bone Health After 70
Your bones are constantly being broken down and rebuilt in a process called remodeling. After 70, the breakdown outpaces the rebuilding. The goal isn't to stop this process — it's to tip the balance back toward building by giving your body the raw materials and mechanical signals it needs.
## The Bone-Building Nutrition Plan
5 Nutritional Priorities for Stronger Bones
## Foods That Build Bones vs. Foods That Weaken Them
Bone-Building vs. Bone-Depleting Foods
| Bone Builders | Serving | Calcium (mg) |
|---|---|---|
| Plain yogurt | 1 cup | 415 |
| Sardines with bones | 3 oz | 325 |
| Fortified orange juice | 1 cup | 300 |
| Collard greens, cooked | 1 cup | 266 |
| Calcium-set tofu | 1/2 cup | 253 |
## Exercise: The Other Half of the Equation
Nutrition provides the raw materials, but exercise provides the signal that tells bones to grow stronger. Weight-bearing exercise — walking, stair climbing, dancing — stimulates bone formation. Resistance training with bands or light weights is even more effective. Studies show that adults over 70 who combine resistance training with adequate calcium and vitamin D can increase bone density by 1-3% per year.
- Walk for 30 minutes daily — this alone reduces hip fracture risk by 40%
- Do resistance band exercises 2-3 times per week targeting major muscle groups
- Try standing heel raises and wall push-ups for weight-bearing bone stimulation
- Balance exercises like Tai Chi reduce fall risk while loading bones
- Avoid high-impact jumping or twisting that could cause fractures in weakened bones
- Swimming and cycling are great for fitness but don't build bone — add weight-bearing activities
## Medications: When Lifestyle Isn't Enough
If your DEXA scan shows a T-score of -2.5 or lower, your doctor may recommend osteoporosis medications. Bisphosphonates like alendronate remain the first-line treatment in 2026, reducing fracture risk by 40-50%. Newer options include denosumab injections every six months and romosozumab for severe cases. These medications work best when combined with the nutrition and exercise strategies above.
## Getting Tested
Every adult over 65 should have a DEXA bone density scan. Medicare covers this test once every two years. If you haven't had one, ask your doctor at your next visit. Knowing your baseline allows you to track whether your bone-building efforts are working.
Start today by calculating your daily calcium intake from food. Most Americans get only 600-800mg daily — far below the 1,200mg target. Close the gap with food first, then supplements if needed.
