Calcium is a vital mineral that not only supports strong bones and teeth but also helps the heart beat, muscles work, and nerves function properly. According to the Cleveland Clinic, 99% of calcium is stored in bones and teeth, while the remaining 1% plays an important role in muscles, tissues, and blood.

Because the body cannot produce calcium on its own, it must come from food or supplements. While many foods are rich in calcium, some can actually drain calcium from the body and weaken bones if consumed too often.

1. Soda (Soft Drinks)
Colas and other sodas often contain phosphoric acid, which blocks calcium absorption and draws calcium from bone tissue. High sugar content further contributes to inflammation and weaker bones over time.

2. Salt (Sodium)
High sodium intake causes the body to excrete more calcium through urine. Fast food, processed snacks, and packaged meals are usually high in salt, so limiting these helps protect bone strength.

3. Caffeine (Coffee, Tea, Energy Drinks)
Too much caffeine increases calcium loss in urine. One to two cups of coffee daily is considered safe, but higher amounts may slowly reduce calcium reserves and increase fracture risks.

4. Alcohol
Excessive drinking reduces calcium absorption, lowers vitamin D levels, and weakens bone-building cells. More than one drink per day for women or two for men increases the risk of osteoporosis.

5. Red and Processed Meats
Processed meats like sausages and bacon are high in phosphorus, which can disrupt calcium balance if intake is too high and calcium intake is low. Moderation is key.

6. Spinach and Rhubarb
These vegetables are rich in oxalates, which bind to calcium and reduce absorption. Pairing them with low-oxalate, calcium-rich vegetables like kale and broccoli can help maintain healthy bones.
