Yeah, fat men have lower testosterone levels. Yeah, non-smokers have lower testosterone levels.
I drink a bunch of HFCS and sugar sweetened beverages. Don't feel like it affects my weightlifting, maybe teeth mostly.
> Other demographic and clinical variables examined as potential confounders included age, sex, race/ethnicity, poverty/income ratio, BMI, serum cotinine, heavy drinker status, and physical activity MET score. BMI (weight/height2) was measured by trained technicians at the NHANES MEC physical examination [19]. Obesity was defined as a BMI ≥30 kg/m2 according to the World Health Organization criteria [20]. Heavy drinker status was defined as respondents who reported consuming alcoholic beverages ≥4 times/week in response to the question “In the past 12 months, how often did you drink any type of alcoholic beverage”? Physical activity was estimated by summing the time spent weekly engaged in activities as reported by participants, multiplied by the metabolic equivalent of task (MET) value for that activity, which yields a MET-h index. One MET is the energy expenditure of 1 kcal/kg body weight per hours [21]. MET-min/week ≥500 was considered physically active, and < 500 MET-min/week was considered non-active.
I haven't finished reading it, but they do seem to have considered these other variables (body fat by using BMI as a proxy).
Carbon dioxide lowers the pH of a drink to 4.5, which is acidic. The acid pH level erodes teeth and one shouldn't brush their teeth too soon after drinking soda because the enamel can be damaged. (Edit: acid on your teeth is always bad, brushing or not.)
Getting a soft drink from a fountain often means getting a straw for your cup as well. Using a straw to drink does help somewhat to bypass the soda from making contact with the teeth in the first place.
Use a straw, save a tooth.
And the negative effect of soft drinks on dental health is primarily from the action of acid-producing bacteria metabolizing sugar. Diet drinks aren't nearly as bad for your teeth, carbonated water barely has any effect.
Using a straw is helpful in all these cases.
Fountain soda ph6.5 to ph8.5 and is a suspension
The differences are stark.
Wait, is this true? Non-smokers have lower testosterone levels. That's weird.
