Take your vitamins
Like people, vegetables that are grown for looks tend to be missing essential ingredients.
According to Science Daily,
A recent study of 43 garden crops ... suggests that their nutrient value has declined in recent decades while farmers have been planting crops designed to improve other traits.
The study was led by Dr. Donald Davis of the university's Biochemical Institute in the Department of Chemistry and Biochemistry. Dr. Davis said—
“Considered as a group, we found that six out of 13 nutrients showed apparently reliable declines between 1950 and 1999.”
These nutrients included protein, calcium, phosphorus, iron, riboflavin and ascorbic acid. The declines, which ranged from 6 percent for protein to 38 percent for riboflavin, raise significant questions about how modern agriculture practices are affecting food crops.
But they didn't check for a number of essential vitamins and minerals—
“Perhaps more worrisome would be declines in nutrients we could not study because they were not reported in 1950 — magnesium, zinc, vitamin B-6, vitamin E and dietary fiber, not to mention phytochemicals....”
