Approximately what percentage of body weight consists of minerals?

2-4%
4-6%
6-8%
8-10%

The correct answer is: 4-6%

Minerals make up a small but critical component of body weight, as they are essential for various physiological functions, including bone structure, muscle function, and enzyme activity. The majority of body weight is comprised of water, proteins, fats, and carbohydrates, but minerals contribute to overall health and metabolism. The human body generally consists of approximately 4-6% of body weight attributed to minerals. This range includes key minerals such as calcium, phosphorus, potassium, sodium, magnesium, and trace elements like iron and zinc, all of which play crucial roles in maintaining health. Understanding the role and proportion of minerals in the body is vital for nutritionists, as it underscores the importance of a balanced diet that includes sufficient mineral intake to support these bodily functions. This knowledge can guide recommendations for dietary adjustments and supplementation when necessary, to ensure individuals meet their mineral needs effectively.
