I’ve been thinking about this the morning as I was walking my dog, and it occurs to me that they are comparing soda drinkers to non-soda drinkers as treated group to a control group.
But there is a general assumption that a control group is relatively homogeneous and we have certainly no evidence of that fact in the non-soda drinkers group. What, exactly, are they consuming in lieu of soda? Water, purified water, distilled water, beer, wine, coffee ( fresh or instant ) , tea, or other poisonous or non-poisonous liquids?
How do the death rates of non-soda drinkers disperse by age verses that of the various soda drinkers sub groups? If there is a toxicity that shortens life span, then we should see some evidence of dose response curves shouldn’t we?
Despite trying many times, I have never developed a taste for coffe or tea, despite likening the boost from their caffeine 😟 so when driving and needing a boost, I get my caffeine from Crystal Light powdered drink mix- grape flavored, with exactly 60mg of caffeine ( a rather modest dose ) Most of the coffees from Starbucks have two or three times the sugar in a 12 ounce Coke, so I don’t drink them either for that reason. Are these Starbucks drinkers in the soda drinking group, or the more virtuous non- soda drinkers group?
Which brings up another point, are the Jolt, Red Bull and the very high caffeine drinks from Starbucks included in the soda drinkers or the non-soda drinkers groups generally?
There is serious well documented medical profession concern about cardiac deaths in young males consuming several Red Bull type of beverages. I have not seen estimates of possible numbers, but I think they are not in single, or even, double digits. I am surprised this hasn’t received bigger press coverage.
These are some of the reasons I have more questions about the originally linked study which I think asks more questions than it answers. Do I think an occasional diet soda causes a 56% greater death rate, that has not been previously recognized? I have doubts, that I know are not shared by more virtuous readers.
@Chris, I didn’t see your post as I was writing mine at the same time.🙂
I do like unsweetened tea, and yet when I look in vending machines, there are countless bottles of sweetened tea with 45->60 grams of sugar, almost 2-3 times the sugar in that standard 12 ounce Coke-Cola. Are the consumers of that sweetened tea in the non-soda drinkers group? In California your convenience stores may offer a lot of unsweetened ice tea, but take a ride across Georgia or Tennesse and look in the coolers of the convenience stores along the route...
The article we are discussing specifically did not see different cancer rates in the soda verses non-soda drinkers if my memory serves.
I must confess the only cases of pancreatic cancer I had exposure to all occurred in very thin patients, two of them were typical Indian males ( Indian as a country on the Indian continent ) very slender. My limited experience is not a statistical survey of course.
