Abstract

Association between food and health is complex. Healthy food can promote and maintain good human health. Healthy food and nutrition is a key regulating factor for boosting the immunity and therapeutic effectiveness of a treatment strategy. Oxidative stress is well involved in the pathogenesis of diverse diseases and aging. Food always considered as good source of nutrients, protein, fat, carbohydrates, vitamins, minerals and antioxidants. Consumed as part of a normal diet, phytochemicals present in food like vitamins (vitamin C & E), minerals (like, zinc, selenium), phytoconstituents (phenolic compounds, flavonoids, carotenoids) confer additional health benefits, by virtue of their antioxidant property. A diet rich that rich in antioxidant molecule reduces the risk of several oxidative stress related diseases. Numerous antioxidant molecules isolated from food showed the curative and health promotion effect. This chapter majorly deals with the role antioxidant/pro-oxidant substances present in different foods on human body.

Good health is elemental to living a productive life, meeting basic needs and contributing to healthy society. The components of health are numerous and their interactions with food are complex. Healthy diet is essential for the success of physical and mental potential for all individuals.

A good food can support human health and improve health potential, and yet can also be an important factor influencing ill health.

In 1980s the name antioxidants came into spotlight when it identified as miracle substances for good health. Food contains numerous biomolecule (antioxidant), which prevent free radical induce diseases, increase immunity and also act as anti-aging molecule. Regular intake of fruits and vegetables has also been shown to protect human from number of diseases, and concurrent scientific investigations have confirmed that antioxidant substances present in those fruits and vegetables are playing a central role for their beneficial effect (Wahlqvist, 2013; Sen & Chakraborty, 2015). Fruits, vegetables and other food can boost the antioxidant capacity of body and thus helpful for human.
