There exists a strong correlation between human nutrition and health, and the human genome. Each individual responds differently to diet. This is due to genetic variations in each individual. Nutritional imbalances during lactation and gestation can contribute to cardiovascular disease, obesity, diabetes, cancer and hypertension. Certain diseases that have genomic anomalies can have consequences on appetite, such as the Prader-Willi syndrome which is characterized by insatiable appetite. Such studies are explored in the domain of nutritional genomics and nutriepigenomics. A crucial area in the study of these fields is obesity. By understanding the interaction between genetic factors and dietary patterns, management of obesity can be possible with targeted dietary changes. This book brings forth some of the most innovative concepts and elucidates the unexplored aspects of genes and their effect on human nutrition. It presents researches and studies performed by experts across the globe on nutritional genomics and nutriepigenomics. With state-of-the-art inputs by acclaimed experts of this field, this book targets students and professionals.
