Micronutrients perform a key role in almost all vital body functions like
those related to vision, immunity, bone formation, brain function and many others that
help in proper growth and maintaining good health. Deficiency of any one or more of
the micronutrients can have a negative impact on the overall health. The causes of
micronutrient deficiencies and their signs and symptoms are explained in this chapter
in a precise manner. Plant and animal food sources with high micronutrient contents
with ready-to-eat food supplements per serving size are illustrated for each
micronutrient. These can serve as a guideline for preventive measures and diet therapy.
Micronutrients are increasingly used as an adjunct therapy in managing various health
problems. Effective therapeutic uses of vitamins and minerals are exemplified for a
ready reference. Overdose of synthetic supplements of micronutrients and certain
environmental conditions may result in toxic effects. To address this, the upper limit
for micronutrient intakes and toxic effects of excess micronutrient intakes are also
described. The relevance of the yogic concept of ‘sattvic’ diet in modern nutrition and
the potential of yoga for micronutrient absorption is also highlighted. The approach of
yoga towards healthy diet and the relation between diet and psychological health is
explained based on experimental data. The importance of specific micronutrients in
health at different stages of life, from pregnancy to old age, is elucidated and remedial
measures are suggested. Lastly, evidence for micronutrient supplements as an adjunct
therapy for COVID-19 is briefly described.
