Minerals, like vitamins, can be toxic when consumed in excessive amounts. While minerals are essential for the proper functioning of the body, an excessive intake can lead to toxicity and adverse health effects. Therefore, it is important to consume minerals in appropriate quantities to maintain a healthy balance.

The correct answer is 9 - 11 kg. The human body contains various minerals such as calcium, phosphorus, potassium, sodium, and magnesium, among others. These minerals play essential roles in maintaining the body's structure, regulating fluid balance, and supporting various physiological processes. While the exact weight of minerals may vary among individuals, it is estimated that the average adult body contains approximately 9 - 11 kg of minerals.

Macro-minerals are essential minerals that are required in larger quantities by the body. The three macro-minerals included in the given list are chloride, potassium, and sodium. These minerals play important roles in various bodily functions. Chloride is necessary for maintaining fluid balance, transmitting nerve impulses, and forming stomach acid. Potassium is involved in muscle function, nerve transmission, and maintaining electrolyte balance. Sodium is crucial for regulating fluid balance, nerve function, and muscle contraction. Fluoride, on the other hand, is not a macro-mineral but a trace mineral that is important for dental health.

Food storage or preparation methods may lead to some loss of minerals, but they do not completely destroy minerals. Cooking methods like boiling, steaming, or grilling can cause some minerals to leach out into the cooking water or be lost through heat. However, the extent of mineral loss depends on factors such as cooking time, temperature, and the type of food being prepared. While there may be some loss of minerals during storage or preparation, it is not accurate to say that they are completely destroyed.

The correct answer is 50% - 60%. The average adult's body weight is generally composed of water within this range. Water is essential for various bodily functions such as digestion, circulation, and temperature regulation. It is also a major component of cells, tissues, and organs. Maintaining proper hydration levels is important for overall health and well-being.

The statement is false because the body does not lose 1.6 liters of water a day. In fact, the average adult loses about 2.5 liters of water per day through various processes such as sweating, breathing, urination, and bowel movements. Therefore, the given statement underestimates the amount of water loss by the body.
