I don't know if I asked you yet wavelength, but are you concerned with about things like aspartame, or hydrogenated fats?
Eyeball I have posted this before:
Aspartame has been unfairly demonized as well. Take this from a purely Scientific Point of view instead of a Conspiracy Theorist one. (The Science and Evidence are totally against the Anti-Aspartame misleading hysteria.
Check this link from the American Cancer Society on Aspartame.
http://www.cancer.org/docroot/PED/content/PED_1_3X_Aspartame.asp?sitearea=PEDAnd here is another from The National Cancer Institute.
http://www.cancer.gov/cancertopics/factsheet/risk/aspartameThe verdict is in on Aspartame. It is totally harmless.
A study of about half a million people, published in 2006, compared people who drank aspartame-containing beverages with those who did not. Results of the study showed that increasing levels of consumption were not associated with any risk of lymphomas, leukemias, or brain cancers in men or women. (Question 2)
Researchers examined the relationship between aspartame intake and 1,888 lymphomas or leukemias and 315 malignant brain cancers among the participants of the NIH-AARP Diet and Health Study from 1995 until 2000. Development of these cancers was not associated with estimated aspartame consumption, refuting a recent animal study with positive findings for lymphomas and leukemias and also contradicting claims regarding brain cancer risk. (Questions 3 and 8 )
