Big Veggies, Small Nutrients

In case you didn't already have enough to worry about, a recent article by the Journal of Horticultural Science and Biotechnology asserts that today's vegetables have fewer nutrients than the ones produced 50 years ago. While today's broccoli, tomatoes, and other produce tend to be larger and more beautiful than the puny specimens of the late 1950's, they allegedly contain between 5% and 40% fewer vitamins and minerals.

One reason for this drop is the so-called "dilution effect." Today's veggies, although bigger than in those of the 1950's, contain roughly the same amount of nutrients. Consequently, their vitamins and minerals are combined with a lot more cellulose and carbohydrates, leading to far fewer nutrients per serving. As larger vegetables are selectively bred to maximize size, this dilution effect grows more and more pronounced.

Another cause that some researchers cite is the industrialization of agriculture. Apparently, monoculture and accelerated growing cycles deplete soil nutrients and ensure that produce spends less time absorbing the nutrients that do exist. Ultimately, these practices further dilute the nutrients in produce.

While dilution is endemic to most forms of agriculture, the industrialization effect can be mitigated by organic and local farming. Organics spend more time in the ground and are exposed to more nutrient-rich soil. While this results in lower yields and higher prices, it also produces vegetables that are more nutritious. In other words, while you might not be able to feed your kids the same high-quality Brussels sprouts that grossed out poor Beaver Cleaver, organic produce might just offer a comparable experience!
