If you have heard my label reading talk, you know that I do not address the issue of food additives. My main focus is on the three ingredients which are the most over consumed in the American food supply and causing the most harm. These are the "bad" fats (saturated, hydrogenated, trans) , refined sugars/sweeteners, and refined carbohydrates/grains.
However, the Center For Science In The Public Interest (CSPI) has just updated their analysis of food additives in the latest edition of Nutrition Action Newsletter and it is available online.
So, for those who are interested, I consider CSPI's work on this over the years, fairly reliable though I do not agree 100% with their ratings. Nor am I recommending that you place the concern over avoiding these additives above and
beyond my guidelines in importance, (unless you are particularly sensitive or have a health issue/allergy with any one in particular) but to use them along with my guidelines, if you choose, as an addendum.
Also, I would add that a "safe" rating by CSPI does not equal a "recommended" rating by me. Personally, I think we should be avoiding all of these additives but clearly, some are more important to avoid then others.
Feel free to discuss any of them in the members forum.
