Calcium – Good for Bones and More
Why is calcium so important?
You need your bones to grow and you want them to be strong in order to support the height you will gain with Super-Growth, for years and years to come. Calcium is what will make it happen.
Calcium is the most abundant mineral in the body and is found mostly in your bones, where it gives them strength. The body does not produce calcium, which means that you must get it from your daily diet. That’s why a diet rich in calcium is so important, particularly when bones are growing and developing. Even after full bone development, you still need an adequate calcium intake throughout your life to keep your bones strong and healthy.
Apart from giving strength to your bones, calcium is necessary for many body functions. Practically every cell in your body, including those in your heart, nerves and muscles, relies on calcium.
In order for your body to function properly, the level of calcium in the blood must stay relatively constant. For this to happen, you need to consume enough calcium throughout the day. Otherwise, your blood will “steal” calcium from your bones to maintain the level it requires. Think of your bones as a “bank”. If your diet is low in calcium, your blood “withdraws” the calcium it needs from your bones. When your diet is rich in calcium, you make “deposits” in your calcium “bank”. Over time, if your withdraws exceed your deposits, your bones can begin to weaken and become more susceptible to breaking.
Smoking, alcohol, and caffeine have a negative impact on bone health, especially if your calcium intake is low.
Provided you consume enough calcium, your bones will continue to grow denser until around the age of 30. After that, calcium remains a priority, because you need to maintain your bone mass to minimize gradual loss associated with aging. As you get older, you tend to shrink (especially women). This tendency can be prevented through sufficient calcium intake.
Your bones need regular physical activity to maintain their strength. Exercise helps your body store calcium in the bones, so that the calcium you get from your diet is used more efficiently.

How to Calculate a Serving
Eating milk products is your best guarantee of getting the calcium you need every day, along with other important nutrients. How many milk products you should eat depends on where you are in your life cycle.
Children aged 4 – 9 years = 2 – 3 servings/day
Youth aged 10 – 16 years = 3 – 4 servings/day
Adults aged 17 and older = 2 – 4 servings/day
What is a Serving?
One serving of milk products contains at least 275 mg of calcium. Not all milk products contain the same amount of calcium. That is why a normal helping of some milk products might give you only ¼, 1/3 or ½ serving as shown below:
1 serving = 250 ml (1 cup) milk
50 g (1” x 1” x 3”) firm cheese
2 slices processed cheese
175 g (¾ cup) yogurt
45 ml (3 Tbsp.) Parmesan cheese
½ serving = 175 ml (¾ cup) ice cream.
125 ml (½ cup) frozen yogurt or ice milk
1/3 serving = 60 ml (¼ cup) ricotta cheese
¼ serving = 125 ml (½ cup) Cottage cheese
There are a lot or good things to say about calcium, but calcium is not so powerful without its “partner” – vitamin D, which enables calcium to build strong bones. Foods rich in vitamin D are fatty fish; milk fortified with vitamin D, and fortified breakfast cereals. Vitamin D can be also manufactured by our bodies from sunlight. The amount of sun exposure needed to produce vitamin D varies with an individual’s skin color and age.
Typically, from 10 minutes to 1½ hours is needed for the body to produce enough vitamin D to reach the fill potential of this “teamwork”. This is one of the reasons why some young people increase their height incredibly during summer time. I want to warn you, however, it can be very dangerous to expose yourself to the sun for long periods of time, because you may get sunburn, heat stroke or worse.
So keep in mind – a game of volleyball on the beach may help your bones to grow!
