Tomatoes No Longer Considered ‘Poison Apples’
Originating in Mesoamerica, tomatoes were part of the Aztecs’ diet as early as 700 A.D., but they weren’t grown in Britain until the 1590s. First arriving in southern Europe in the early 16th century via Spanish conquistadors returning from Mesoamerica, the tomato was considered a “poison apple” for nearly 200 years because some aristocrats died when the acid in tomatoes leached lead from pewter plates. Europe began embracing the tomato after the invention of pizza in Naples around the 1880s, but it took England and America a while to come around. Today, tomatoes are the world’s highest-
called volatiles (which stimulate smell receptors). “The tomato is not like many of the common fruits you might think of, like bananas or strawberries, where if I just gave you one volatile you’d say, ‘Oh, that’s a banana,’” said Harry J. Klee, crops genetics researcher and professor of horticultural sciences at the University of Florida. “There are at least 25 different volatile chemicals and aroma compounds that contribute to the flavor of a tomato. Of those volatiles, 13 are significantly reduced in the modern varieties.” Although the researchers believe it’s possible to improve the flavor of commercially produced tomatoes, there are some caveats: Commercial crop yields will drop by 10 percent; the price will increase; and they will never be as flavorful as locally produced vine varieties.
Your Diet Can Change Your DNA
Recent studies suggest what we eat could modify our genes and potentially those of future generations. Epigenetics is the study of how different biological and environmental signals affect gene expression. Rather than change DNA itself, epigenetic signals can, for example, prompt changes in the number of methyl chemical groups attached to a gene, turning it on or off. Diets are
important sources of epigenetic signals. Scientists are investigating how eating habits modify gene expression in adults and their offspring. A famous example is the Dutch Hunger Winter in 1944, when a famine struck the western Netherlands, forcing the population to live on between 400-
