Biology class presentation on calcium

NOTE: You MUST follow the outline below, ONLY!!

Create a 13 slides long presentation, based on the outline provided, and answer the questions on the following topic: Calcium absorption in human body: Do we need to use Dairy dietary sources or non-dairy?

Discuss the importance of calcium for human body, its way of absorption and bioavailability of calcium in dairy AND non-dairy products

(Our intention is to show how milk is not the absolute best source of calcium for human body)

***DO NOT USE ANY RESOURCES OTHER THAN THE ONES PROVIDED BELOW!!***

Slide 1: Topic, Introduce ourselves: Bodily calcium absorption: With an emphasis on Dairy dietary sources vs non-dairy.

Slide 2+3: Introduction: What is Caclium and why our body needs it?

Calcium (Ca)

• One of the many inorganic dietary minerals that our body needs in order to function properly.
• On average our body needs at least 200mg of calcium.
• Sources: dairy products, dark green vegetables, legumes
• Major functions in the body: Bone and tooth formation, blood clotting, nerve and muscle function
• Calcium deficiency results in —> Impaired growth, loss of bone mass

Slide 4+5: History: Have humans always been obtaining their calcium from dairy products?

Domesticating of cows and evolvement of milk drinking by humans:
