The nutritional health in the world is one of the most pressing issues in front of different countries today. International organizations like FAO and WHO suggest that there is an improvement of the nutritional situation in Asia and Latin America, though deterioration in sub-Saharan Africa does exist. As regards Europe and USA, we are living in the era of “overnutrition” though the situations of famine, hunger, and starvation do exist in some developing countries. Some of the noncommunicable pathologies like obesity are not only due to the excess of fatty food, but intake of unbalanced diet also contributes significantly to their pathogenesis. Obesity is also associated with cancer prevalence as excess of calories might contribute to the neovascularization. Nutrient requirements vary as a function of life style. Infants and pregnancy require more attention because these situations are more vulnerable and are at greater risk for malnutrition that might contribute to metabolic memory, responsible for the pathologies like macrosomia, obesity, type 2 diabetes, and hypertension.

The fundamental research at the cellular and molecular level is indispensable for the patient-related nutrition. The nutritional therapies, besides enteral and parenteral approaches, also include an integrated holistic approach to health by functional food or phototherapy. The nutrition/malnutrition modulates the epigenetic fingerprinting that might be implicated in different pathophysiological situations.
