Definition
Digest refers to the process of breaking down food into smaller molecules that can be absorbed by our body. It involves mechanical (chewing) and chemical (enzymes) processes occurring in different parts of our digestive system.
Proteins that speed up chemical reactions without being consumed themselves. They play a vital role in breaking down complex nutrients during digestion.
Stomach Acid: A strong acid secreted by cells lining the stomach walls that helps with protein digestion and kills bacteria present in food.
Small Intestine: The longest part of our digestive tract where most nutrient absorption takes place, aided by various enzymes and other digestive juices.
