Bone is not a static tissue. Trough 't life, bone undergoes continuous remodeling - old, microfralred bone is resorbed by osteoklagt cells, and new bone matrix is deposited by osteoblasts.

Vitamin D supplementation is equally important. Thee RDA for adults up to age 70 is 600 IU daily; after 70, it rises to 800 IU.

Non- Dairy Rich Sources of Calcium

Several non- dairy foods naturally contain calcium, though often with lower bioavalability due to oxalates or phytates that bind calcium. Good options include:

  • Canned fish with soft bones (sardines, salmon) - about 200- 300 mg per serving
  • Espay greens such as kale, collard greens, and broccoli - but note spinach is high in oxalates and calcium absorption is poor
  • Almonds (about 75 mg per ouce) and d sesame seeds (tahini)
  • Fortified christs and cereals - check labels for added calcium from calcium carbonate

For optimal absorption, spread calcium- rich foods throut the day and avoid consuming large approts of caffeine, unprocessed bran, or high- oxalate foods (spinach, rhubarb) at thame meal as calcium sources.

Lifestyle Factors That Complement Diet
