The human body consists of 70% of water
Analysis
The claim that the human body consists of 70% water is a common simplification but not entirely accurate across all individuals. Most scientific and medical sources indicate that the average adult human body contains approximately 60% water, with variations depending on age, sex, body composition, and health status. For example, men typically have a higher percentage of body water than women due to differences in fat and muscle mass. Some organs like the brain and lungs have higher water content (around 70-80%), which may contribute to the origin of the 70% figure. However, the overall body water percentage rarely reaches 70% in a typical adult. Therefore, while the claim is not entirely false, it overstates the average water content in the human body and lacks nuance.

Provides ranges (45-65%) depending on sex, showing variability below 70%.
Gives an average of roughly 60%, not 70%, supporting a lower figure.

Focuses on methods for body composition measurement, does not support the 70% claim.
Discusses water in gut lumen, not total body water percentage, not supporting the claim.
Talks about water distribution but does not confirm a 70% total body water figure.
Notes fat tissue has less water, affecting overall percentage, implying less than 70%.
