If Americans ate just one more serving of fruits or vegetables per day, this would save more than 30,000 lives and $5 billion in medical costs each year.
If Americans were to follow current USDA recommendations for daily consumption of fruits and vegetables, those numbers would go up to more than 127,000 lives and $17 billion saved.
The increased longevity that would result if Americans ate the recommended amount of fruits and vegetables is worth over $11 trillion.
Genetics is the study of genes, genetic variation, and heredity in living organisms. A gene is the basic physical and functional unit of heredity. Genes, which are made up of DNA, act as instructions to make molecules called proteins.
The Human Genome Project has estimated that humans have 20,000 - 25,000 genes. Every person has two copies of each gene, one inherited from each parent. Most genes are the same in all people, but less than 1% of genes are slightly different between people. Poplar tree genome suggests more than 45,000 genes.
