Health
For an organism to survive, it must remain in good health. Diet is concerned with the nutrients that an organism receives from food. In the case of humans, a balanced diet is ensuring we have enough carbohydrate, protein, fibre, fat, and vitamins and minerals for our cells to carry out their chemical processes that keep us alive and well. To complicate matters, humans have introduced the use of drugs such as caffeine, alcohol, and nicotine, which can each cause health complications.
