Food is a carrier of nutrients and to get the nutrients we need, exposure to the right foods is required. This basic fact underlies the most basic nutritional principle: eat a wide variety of foods.
Although it seems like a simple and easy principle to follow, most people tend to consume the same foods over and over again. This is due to custom, time constraints, working conditions, and food desires and dislikes. However, it is clear that a monotonous intake of this type will end up causing some degree of malnutrition.
In the case of the athlete, some loss of potential in performance. Perhaps, it is because of this misunderstanding that eating a wide variety of foods is critical to optimal nutrition, coupled with the understanding that doing this is difficult, that so many athletes turn to supplements of nutrients and others nutritional products: They are trying to lessen their underlying fear that they are simply not eating well to perform well. Thus, athletes usually go from being from malnourished by food to being overfed by supplements. Neither condition will help you achieve your goals. However, it is clear that many coaches and athletes do not know how nutrients work and how the human body deals with nutritional errors.
The best way to think about optimal nutritional status is by analogy with the microeconomic theory of supply and demand. Each cell has nutritional needs. If you provide too much, it must expend energy and effort to get rid of the excess. If you give it too little, the cell malfunctions. Every cell has a demand for nutrients, and your job is to supply it with what it needs when it needs it.
