Women who reported consuming the most fruits and vegetables (8 to 9 servings a day for a 2,000-calorie diet) in their 20s were 40% less likely to have calcified plaque in their arteries in their 40s compared with those who ate the least amount (3 to 4 servings a day) during the same time period.
This association persisted even after researchers accounted for other lifestyle behaviors, as well as for their current-day diets, further demonstrating the role dietary patterns at younger ages may play.
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.
