Which type of vitamins must be included in the diet to support bodily processes?

Vitamins are essential organic compounds that the body requires in small amounts to support a variety of physiological processes. They play critical roles in metabolism, immune function, and cell function, and are necessary for the proper functioning of enzymes and hormones. Each vitamin has specific roles; for example, vitamins A, C, D, E, and the B vitamins contribute significantly to functions ranging from vision and skin health to energy production and red blood cell formation.

Since the body cannot synthesize most vitamins in adequate amounts, they must be obtained through diet. This underscores their necessity as integral components of nutrition and health.

Minerals, while important, are inorganic elements and therefore not classified as vitamins. Fats and proteins are macronutrients that provide energy and serve as building blocks for body tissues but do not fit the specific requirements that vitamins fulfill. Thus, including vitamins in the diet is crucial for maintaining overall health and supporting various bodily processes.
