Nutrient links—the interrelationship between different dietary components

It is well known that the human body requires many different nutrients for its growth and healthy maintenance. Some nutrients are required in relatively large amounts, namely the carbohydrates, fats and proteins, whilst others are needed only in small amounts. The latter include the vitamins, minerals and trace elements. The requirement of each different nutrient has been ascertained with a reasonable degree of accuracy for the varying ages and types of mankind. For optimal health the requirements of each nutrient have to be met in the food eaten by every individual.
