Douglas A. Palmer, Industrial Research Scientist PNT, Inc. 92122 Re: Good correlations, invaid conclusions Email Douglas A. Palmer: dpalmer@cox.net The two assumptions in this study: 1) That Northerners and Southerners eat identical diets and 2) that Southerners receive greater UV doses are unfounded and lead to an incorrect conclusion. Regarding assumption 1: One example, consumption of dairy products, correlates very highly with latitude in the continental U.S. Many epidemiological studies have shown correlations between the consumption of dairy products and prevalence of cancers such as prostate, breast and ovarian. Another, tomatoes. Examination of USDA records will show correlations of diet and state. Regarding assumption 2: From skin cancer studies it has been shown that people from Northern latitudes often receive extremely high instantaneous (burning) doses of UV during holidays resulting in very high exposures to Vitamin D. People from SOuthern latitudes tend to take in UV in much lower instantaneous doses. Remember we are NOT Doctors and have NO medical training.
