1. What are the proportions of our body weight? (The nutrients and substances)
The proportions of our body weight can vary depending on factors such as age, sex, and overall health. However, on average, the following are the approximate proportions of our body weight in terms of nutrients and substances:
1. Water: Approximately 60-70% of our body weight is water. Water is essential for various bodily functions, including digestion, circulation, and temperature regulation.
2. Protein: Protein makes up around 15-20% of our body weight. It plays a crucial role in building and repairing tissues, as well as producing enzymes, hormones, and antibodies.
3. Fat: Fat accounts for roughly 15-30% of our body weight, depending on factors like gender and body composition. While excessive fat can be detrimental to health, some amount of it is necessary for insulation, energy storage, and cushioning organs.
4. Minerals: Minerals such as calcium, phosphorus, potassium, magnesium, and others make up less than 1% of our body weight. However, they are vital for maintaining healthy bones, teeth, and bodily functions.
5. Carbohydrates: Carbohydrates constitute around 1-2% of our body weight. They are the primary source of energy for our bodies and are found in foods like grains, fruits, and vegetables.
6. Vitamins: Vitamins are required in small amounts and do not significantly contribute to body weight. However, they are essential for normal growth, development, and overall well-being.
It's important to note that these proportions may vary from person to person, and an individual's body weight can also include other substances like hormones, enzymes, and various other molecules.
