  • The Organic Consumers Association cites several other studies with similar findings: A Kushi Institute analysis of nutrient data from 1975 to 1997 found that average calcium levels in 12 fresh vegetables dropped 27 percent; iron levels 37 percent; vitamin A levels 21 percent, and vitamin C levels 30 percent. A similar study of British nutrient data from 1930 to 1980, published in the British Food Journal,found that in 20 vegetables the average calcium content had declined 19 percent; iron 22 percent; and potassium 14 percent. Yet another study concluded that one would have to eat eight oranges today to derive the same amount of Vitamin A as our grandparents would have gotten from one.

    I didn’t consult their methodology, but these figures aren’t too out of alignment. However, take with a grain of salt. Sure, maybe Vitamin A has decreased in oranges. They have 2 out of a recommended 900 mcg of it, you were not going to eat 450 oranges to hit your vitamin A goals for the day.


  • US based optometrists are licensed medical providers, credentialed to diagnose and treat eye disease, including prescriptions for controlled substances. They are sometimes covered by medical insurance. The major scope of practice difference is that optometrists generally may not perform invasive surgery (though there are a few states that do allow optometrists to perform LASIK or post-cataract surgery laser procedures).

    There are plenty of optometrists who work in glasses/contact lens shops and that’s all they do. I wouldn’t trust them to treat eye medical issues, at the very least because that’s not what they commonly do all day. Larger optometry groups or optometrists that work in an ophthalmology group are more suited to disease care.

    Ophthalmologists do have more training (they are medical doctors first with a 3-4 year eye specialty and sometimes a 1-2 year Fellowship training for subspecialists).
