Sodium Sulfite – toxicity, side effects, diseases and ...
Sodium sulfite is a food additive meant to preserve the freshness of various items. Its use was quite rampant during the early 1960s to 1970s until the U.S. Food and Drug Administration (FDA) restricted its use in 1986. This was in response to the slew of adverse effects being noted by people who consumed fresh produce that contained sodium sulfite.
