Biotechnology and potential nutritional implications for children.
The tools of biotechnology have enormous potential to develop new, safe, and nutritious foods and food products that could benefit the immediate and long-term nutritional and health needs of the pediatric population. This is especially true as more emphasis is placed on the prevention, rather than the treatment, of chronic degenerative and metabolic diseases. But the promise of biotechnology for nutritional and health benefits of children's diets must be accepted with cautious optimism. Many advances in food technology and nutritional composition of food animals and plants have already been made through biotechnology, but they represent only the beginning of the necessary research. These advances have been based on relatively little knowledge of basic human nutritional needs, particularly during the dynamic pediatric period of growth and development. More importantly, these advances have been predicated with no understanding of dietary nutrient interactions. Changing nutrient composition of foods through biotechnology may alter nutrient interactions, nutrient-gene interactions, nutrient bioavailability, nutrient potency, and nutrient metabolism. Biotechnology has the potential to produce changes in our foods and in our diet at a pace far greater than our ability to predict the significance of those changes on pediatric nutrition. The Human Genome Project, which relies on biotechnology, will revolutionize science and medicine. Pediatrics will be one of the first medical specialties to benefit from the outcome of this project as recombinant DNA manipulations will replace diet therapies for treating metabolic diseases. Somatic gene therapy eventually may be the ideal means for diagnosis, treatment, and cure of inherited diseases and metabolic disorders; however, many problems exist, especially in situations in which nutrients are involved in the complex regulation of gene expression. DNA and genes themselves do not determine the fate of an individual. The genetic material provides the potential for the individual, but this potential can be modified by environmental factors. The interaction of nutrients with genes is a major determinant in the final outcome of the individual. Biotechnology promises children a more productive and better quality of life, but achieving the full potential of this promise demands a continued diligent search for knowledge of nutrition and nutrient-gene interactions.
