Over 90% of the protein ingested is broken down into its basic building blocks, known as amino acids, during digestion. This fundamental biological process, called proteolysis or hydrolysis, is vital for the body's ability to use dietary protein for building, repairing, and regulating tissues and cells. The breakdown of proteins is a multi-step process involving specific enzymes and conditions in the digestive tract.

Studies have shown that caffeine stimulates gastric acid secretion via bitter taste receptors, a fact that sheds light on a common digestive dilemma. Yes, **caffeine does stimulate acid production**, an effect that can lead to digestive discomfort for many, though the response varies widely among individuals.

The intricate mechanism ensures this vital nutrient, essential for nerve function and DNA synthesis, is efficiently extracted from our diet, but it requires a perfectly functioning digestive system.

Despite being insoluble in water, the human body is highly efficient at digesting and absorbing lipids through a series of specialized steps involving enzymes and emulsifiers. So, to answer the question, 'Can humans digest lipids?' the answer is a definitive yes. This complex process is vital for providing energy, absorbing fat-soluble vitamins, and building cell membranes.

Within minutes of drinking, water can begin its rapid journey through the digestive system. Instead of being "digested" like food, it is efficiently absorbed by the body, with most of this process occurring past the stomach. Understanding what happens to water once it reaches your stomach reveals the body's remarkable efficiency in maintaining hydration.
