| 3 | Alcohol (2 drinks/day) | Impairs osteoblast activity, the cells that build bone. | Lowalcohol wine or a flavorful mocktail. |
| 4 | Caffeinated beverages (>3 cups) | Increases calcium excretion through urine. | Decaf tea, herbal infusions, or waterrich smoothies. |
| 5 | Highfat red meat | Saturated fat hinders vitaminD activation, reducing calcium absorption. | Lean poultry, fish, or plantbased proteins like lentils. |
