While the myth that your stomach is the size of your palm is a popular one often used for portion control, the reality is far more complex. The human stomach is a muscular, hollow organ that can stretch and contract significantly, with its size varying depending on whether it is empty or full.

Over 99% of the body's total calcium supply is stored in the bones and teeth. This fact reveals that the most common mineral found in the human body is calcium, a powerhouse nutrient critical for much more than just skeletal strength.

According to the National Institutes of Health, bones consist of about 60% inorganic minerals and 30% organic materials, meaning bones are not proteins. This common misconception stems from the fact that a significant portion of the bone's organic material is, in fact, a protein known as collagen.

The small intestine, despite its name, is the longest part of the gastrointestinal tract, responsible for over 90% of nutrient absorption. It is the primary site where the final breakdown and absorption of carbohydrates, proteins, and fats take place. This critical process ensures your body gets the energy and building blocks it needs from the foods you eat.

The human digestive tract is a marvel of biological engineering, a 30-foot-long tube working tirelessly to fuel our bodies. The process of eating, and subsequently digestion, is a complex, multi-stage operation that begins long before you even take the first bite and is fundamental to our survival.

The human stomach is an incredibly elastic organ, capable of holding up to 4 liters of food and liquid, or more than 75 times its empty volume. This dynamic ability to stretch and contract completely upends the common belief that its capacity is limited to the size of a clenched fist.

According to the World Gastroenterology Organisation, digestive diseases impact more than 20% of the global population, beginning with the fundamental step of taking in food. The word for taking in food is 'ingestion,' a crucial process that precedes digestion and provides the body with the raw materials needed for energy and growth. This initial phase sets the stage for everything that follows in the complex human digestive system.

Did you know that after water, protein is the most abundant molecule in the human body, found in virtually every tissue? The question, "Does tissue have protein?", has a vastly different answer depending on whether you're referring to biological tissue or paper.

Contrary to the widespread belief that our bodies are 90% water, the average adult human body is actually composed of closer to 60% water. This common misconception vastly overstates our fluid content, which varies significantly based on age, gender, and body composition.

Did you know that water, not protein, is the largest single component of your muscle tissue? While protein is essential for building and repairing muscle, studies show that skeletal muscle consists of approximately 70% to 75% water and 18% to 23% protein. Understanding this key ratio is vital for optimizing muscle function, recovery, and overall health.
