The human body requires nutrients and calories from meats, vegetables, grains and dairy products. These food groups provide three types of nutrients that give energy to the body: fats, carbohydrates and proteins. Fats are used for long-term energy, carbohydrates are employed for energy in the short term and proteins act as the building blocks of human tissue. Obesity and malnutrition are well-known dangers of eating an unbalanced diet, but there are other, less-known hazards.

Electrolytes are chemical compounds that conduct electrical charges. In the human body, electrolytes help the nervous system send electrical impulses as instructions for the body to operate. According to MedicineNet, common electrolytes in the human body include sodium, potassium, chloride and bicarbonate. For example, a deficiency of potassium in blood due to not eating fruits such as bananas can cause heart arrhythmia, or irregular heartbeat, which can be fatal.
Immune System Weakness
White blood cells are the building blocks of the immune system and are created in bone marrow and lymph nodes. They intercept and destroy foreign bacteria, preventing the body from becoming infected. According to Clermont College at the University of Cincinnati, a strong immune system requires a diet rich in vitamins A, C and E, as well as zinc. Without these nutrients the body cannot easily produce white blood cells. Green leafy vegetables, such as spinach and lettuce, provide vitamins C and E, while carrots provide vitamin A, which also benefits eyesight.
A poor diet can negatively affect mental and physical health. For instance, consuming a diet lacking in vitamin D can contribute to depression. According to Women to Women, you can find vitamin D in fatty fish such as salmon as well as from milk and other dairy products. Vitamin D aids in the production and transmission of critical neurotransmitters, such as serotonin and dopamine.
