Currently setting a bio-social frame, research shows that nutrition represents a voluntary, conscious and educable process (Williams, 2016). Keeping the same context, we talk about nutrition as a complex process that involves digesting food and turning it into absorbable nutrients and waste disposal.

Worldwide presented statistical data shows that the following figures are in a strong conflict: while malnutrition affects 1 out of 2 inhabitants of the planet, there are about 1.5 billion overweight people and 500 million are obese (Godfray, & Garnett, 2014).

In the US, one out of three adults is overweight, a person out of three is obese and thereby only one adult out of three is in normal weight ranges. Currently 40% of non-transmissible diseases deaths are due to the consumption of high calorie foods, salt, saturated fat acids, unsaturated fat acids and sugar, while the low consumption of fruits and vegetables causes 1.5 million deaths each year (Flegal, Carroll, Ogden, & Curtin, 2010).
