Mineral Makeover: The Power of Calcium

Calcium is an essential mineral that plays a crucial role in various bodily functions. It is especially important for athletes and individuals looking to optimize their performance, as it contributes to muscle contractions, nervous system regulation, blood pressure stabilization, blood clotting, and hormone release.

Why Calcium Matters

Did you know that 99% of your body’s calcium is stored in your teeth and bones? While this may seem like a small percentage, the remaining 1% circulating in your blood is vital for maintaining overall health and supporting physical activities.

Athletes, in particular, put their bodies through intense physical demands during practices, matches, and lifting sessions. Jumping, landing, spiking, digging, and changing directions all require quick reaction times, powerful muscle contractions, and a strong skeleton. And calcium plays a key role in enabling these movements.

The Importance of Calcium for Teens and Young Adults

Adolescence is a critical period for bone formation and growth. It is during this time that peak bone density occurs, which sets the foundation for lifelong bone health. Therefore, it is crucial for teens and young adults to consume enough calcium-rich foods to support optimal bone mass and strength.

It’s worth noting that teenagers require around 1,300 milligrams of calcium daily, which is approximately 300 milligrams more than younger children or middle-aged adults. Unfortunately, this is also a period when athletes may be at risk of poor calcium intake.

Factors Affecting Calcium Deficit

Certain factors can increase an individual’s risk of calcium deficit. These include:

  • Limited caloric intake or a food-restrictive diet
  • Heavy sweating (as calcium is one of the electrolytes lost in sweat)
  • Following a vegetarian or vegan diet
  • Lactose intolerance

If you fall into any of these categories, it’s essential to ensure you’re getting enough calcium through your diet.

Calcium-Rich Foods to Include in Your Diet

To meet your daily calcium requirements, aim to include 3-4 servings of calcium-rich foods in your meals. Remember, calcium is best absorbed in smaller amounts throughout the day rather than in fewer, larger servings.

Here are some excellent sources of calcium:

Animal-based Sources

  • Mozzarella, Swiss, Parmesan, Cheddar: 1.5 oz provides 300-500 mg of calcium
  • Yogurt: 1 cup provides 400 mg of calcium
  • Ricotta: 1/2 cup provides 300 mg of calcium
  • Fish with bones (canned sardines, salmon): 3 oz provides 200-370 mg of calcium
  • Cottage Cheese: 1 cup provides 250 mg of calcium

Plant-based Sources

  • Soymilk, almond milk (fortified): 1 cup provides 200-400 mg of calcium
  • Orange juice (fortified): 1 cup provides 300 mg of calcium
  • Tofu (calcium added): 1/2 cup provides 250-750 mg of calcium
  • Spinach, collard greens, kale (cooked): 1 cup provides 20-280 mg of calcium
  • Sesame, chia seeds: 1 oz provides 200-280 mg of calcium
  • Soybeans (edamame): 1 cup provides 200 mg of calcium
  • Almonds: 1/4 cup provides 100 mg of calcium

Remember to check nutrition labels for the calcium content of the foods you consume. To quickly determine the amount of calcium, add a zero to the % daily value (DV). For example, if the DV is 10%, the food contains 100 mg of calcium.
