Question

Why does nutrition needed for human beings

Answer 1

The human body requires six essential nutrients that are found in food – carbohydrates, protein, fats, vitamins, minerals and water. These nutrients are vital since they provide energy and fuel for the body to regulate metabolic processes and build or repair tissues.

Answer 2

Without proper nutrition, your body can’t survive. When you eat a balanced diet, your body obtains the fuel and nutrients it needs to accomplish various bodily tasks. For example, your body needs minerals to make hormones, build bones and regulate your heartbeat. Examples of minerals include calcium, sodium, potassium, iron, iodine and copper. Water is another essential component of your diet. Without it, your body can’t flush out toxins, transport nutrients to cells or perform other vital bodily processes.
