Emphasizes the importance of calcium for health, not just its chemical properties.

Incorporating calcium-rich foods like milk and cheese can help maintain healthy bones.
Common Sources
Identify foods high in calcium, rather than just stating its presence.

Leafy greens are a surprisingly good source of calcium.
Health Issues
Links the term with medical conditions caused by lack of calcium.

in the joints for example the knee and I take the cells from the cartilage and actually there there are a lot of examples of cartilage injuries in the sports in arthritis so I'm working now on diminishing those so I take hearts of cells and the important thing is actually this they have the same calcium

The surprising reason...
Even when ions like sodium, potassium or calcium are depleted in or around the muscle cell, these ions are plentiful elsewhere in the body. With a little time, they will flow back to the areas where they’re needed, sometimes with the help of active sodium and potassium pumps.

The chick has been absorbing calcium from the shell into its own bones, making itself stronger and the shell weaker. Not only that, but it also used the shells calcium to create a tool to help it break free. A hard, jagged tip on the end of its beak, an egg tooth.

based on medullary tissue found on the inside of the bone. Medullary tissue is the calcium build-up, the calcium storage basically, when an animal is pregnant, when a bird is pregnant. So here was the character that linked birds and dinosaurs.

How do vitamins work? -...
helps shape bones and improves vision by keeping the cells of the eye in check. Vitamin D gathers calcium and phosphorus so we can make bones, and vitamin E works as an antioxidant, getting rid of elements in the body that can damage cells.

their flesh and the deep sea is under saturated in calcium carbonate so it literally dissolved all the bones takes about five years but the entire skeleton of a human at those depths will vanish and what's left behind are there pairs

The science of skin...
an ingredient that strengthens bones and lets us absorb vital minerals, like calcium, iron, magnesium, phosphate, and zinc. Without it, humans experience serious fatigue and weakened bones that can cause a condition known as rickets.

Foods like potato chips, spinach, rhubarb, and beets are high in oxalate, so doctors might advise limiting them. Even though calcium is often found in stones, calcium in foods and beverages can actually help
Video examples
What causes cavities? -...
but unfortunately, our teeth aren't. While each human tooth is coated in a hardy, protective layer of enamel, it's no match for acid. That degrades the armor over time, leaching away its calcium minerals.

Quote examples
Philippe Cousteau, Jr.
American Scientist
Ocean acidification is often referred to as osteoporosis of the oceans because as acidity rises, shell building creatures such as lobster, oyster, crab, shrimp, and coral are unable to extract the calcium carbonate from the water that they need to build their shells and are thus unable to survive.

Quote examples
Friedrich Bergius
German Scientist
Even in the investigations into direct production of calcium peroxide in an alkali melt with highly compressed oxygen, it was found to be necessary to bring the high-pressure gas into contact with the suspension of lime in caustic alkali melt by agitation or some other means of mixing.

Quote examples
David Kirsch
American Scientist
Despite popular belief that watermelon is made up of only water and sugar, watermelon is actually a nutrient-dense food with a high amount of vitamins such as A and C, minerals such as iron and calcium, and is high in antioxidants.

Quote examples
Raquel Welch
American Actress
I take a multivitamin, I take extra C, I take chondroitin and glucosamine for my joints, I take calcium for my bones. And by the way, weight-bearing exercises can help ward off osteoporosis and yoga helps ward off arthritis.

Quote examples
Gro Harlem Brundtland
Norwegian Politician
Such lifestyle factors such as cigarette smoking, excessive alcohol consumption, little physical activity and low dietary calcium intake are risk factors for osteoporosis as well as for many other non-communicable diseases.

Quote examples
Lauren Wasser
I have a golden leg that I am completely proud of, but my left foot that has an open ulcer, no heel, and no toes. Over the years, my body has produced a lot of calcium, which causes my bones to grow on that foot.

Quote examples
Hannah Bronfman
American Businessman
When you really listen to what your body is telling you, it's easy to treat it well. For example, if my fingernails are weak, I know I need more calcium. If I have dry skin, I'm dehydrated or need to exfoliate.

Quote examples
Ingrid Newkirk
British Activist
Fortified plant-based milks are delicious and contain all the calcium, protein, and vitamin D of dairy products but with none of the cholesterol, lactose, hormones, or cruelty found in cow's milk.

Quote examples
Joel Fuhrman
American Scientist
High salt intake is a risk factor for osteoporosis because excess dietary sodium promotes urinary calcium loss, leading to calcium loss from bone and therefore decreased bone density.

Quote examples
Andrew Weil
American Scientist
Most American diets, even bad ones, provide more than enough calcium for bone health, especially for men.
