Most of what we've been taught about depression and its causes is not valid. Most so called anti-depressant pharmaceuticals don’t work. And, if taken long term they can seriously undermine your health and screw up your metabolism so that it can become very difficult to unwind the mess. A mounting mass of evidence shows that antidepressants are no better than placebos when it comes to the benefits they have long thought to bestow. An amazing 20% of Americans over the age of 12 are still being stuffed full of antidepressant drugs as are older men and women who have often taken these drugs for years. One in 10 Americans still take antidepressants as well as one in four women in their 40s and 50s.  So do 13 percent of pregnant women.  Meanwhile doctors continue to prescribe them—especially selective serotonin reuptake inhibitors (SSRIs) despite a growing number of studies showing that these drugs can also put a pregnant woman at risk of giving birth to a child with severe birth defects or autism.
