Stomach Function
Small Intestine
Molecular Breakdown
Nutrient Utilization and Body Function
1:19 - 2:08
How digested molecules are used for energy and building body tissues, including the role of micronutrients.

4:56 - 6:11
Explains the difference between food poisoning and feeling sick from overeating engineered foods.
Food Poisoning
Bacterial Toxins
Engineered Foods
Overeating
The Transformation of Food into Waste
6:11 - 7:35
Details the process of how food is converted into waste products, including the role of fiber and gut bacteria.

Questions This Video Answers
Why is digestion necessary?
Digestion breaks down food into smaller molecules that can be absorbed into the bloodstream and used for energy and building the body. Without digestion, the body cannot properly utilize the nutrients in food.
Why do I feel sleepy after eating?
Digesting food requires energy and blood flow to the digestive organs. This can lead to a temporary decrease in energy levels and a feeling of sleepiness, especially after consuming large, carbohydrate-rich meals.
Why does food sometimes make me feel sick?
Food can make you feel sick due to food poisoning from bacteria or viruses, or from overeating highly palatable, engineered foods that are designed to be consumed in excess.
What actually becomes poo?
Poo is primarily composed of undigested fiber, dead and living bacteria from the gut, and waste products from the breakdown of old red blood cells. Most of the food is converted into breath and energy.
