The average 70 kg adult human body is made up of approximately $7 \times 10^{27}$ atoms. While much of this mass is from organic compounds, the question of "are humans made of minerals?" reveals a fundamental truth about our composition: we are a complex combination of both organic and inorganic substances. These essential inorganic minerals play critical roles far beyond just bone structure.

While commonly cited, the claim that the human body is 75 percent water is misleading, as the percentage varies significantly based on factors like age, gender, and body fat content. The actual average for a healthy adult is closer to 60%, with infants having the highest concentration at birth.

While water is the most abundant molecule overall, when it comes to the large organic molecules known as macromolecules, one type dominates the human body. Proteins are the most abundant macromolecules, performing a diverse array of functions critical for life.

The human body is made up of approximately 50 to 70% water, with the average adult having around 60% of their total body weight comprised of this essential fluid. This percentage varies significantly based on age, gender, and body composition, with infants having a much higher proportion and older adults a lower one.

Over 60% of the average adult human body is composed of water, making the viral claim that our body contains 90% of water completely false. This common misconception dramatically overstates the actual percentage, which varies significantly depending on several key biological factors throughout a person's life.

Over 99% of the body's calcium is stored in the bones and teeth, making it the most abundant mineral in the human body. This essential element is foundational for skeletal structure, but its importance extends far beyond strong bones to influence crucial physiological processes, including muscle movement and nerve signaling.

Approximately 60% of the adult human body is water, making it the most abundant and vital nutrient for survival. Without a sufficient intake of this essential compound, all physiological processes—from regulating body temperature to transporting nutrients—would cease to function effectively.

On average, the human adult body is composed of approximately 60% water. This crucial fluid percentage is not static and varies significantly based on factors such as age, gender, and overall body composition.

The human body contains approximately seven grams of the trace element silicon, from which nutritional silica is derived. Though often overlooked, this element plays a critical role in numerous biological functions. So, do humans have silica in their bodies? The scientific consensus confirms its vital presence and function for overall health.

While the 70 percent water figure is a popular myth, the actual amount of water in the human body varies significantly, typically ranging between 50% and 75%. Factors such as age, gender, and body composition all play a crucial role in determining the true proportion of water, making the blanket statement 'your body is 70 percent water' a widespread inaccuracy.
