…the United States is the only developed country in the world that still fluoridates its citizens’ drinking water?

10 facts you need to know about fluoride:

1. More people in the U.S. drink fluoridated water than the rest of the world combined.
2. Fluoridated countries do not have less tooth decay than non-fluoridated countries.
3. According to a 500-page scientific review, fluoride is an endocrine disruptor that can affect your bones, brain, thyroid gland, pineal gland and even your blood sugar levels.
4. Fluoride is naturally occurring in some areas, leading to high levels in certain water supplies “naturally.” Fluoridation advocates often use this to support its safety, however naturally occurring substances are not automatically safe (think of arsenic, for instance).
5. About 40 percent of American teens have dental fluorosis, a condition that refers to changes in the appearance of tooth enamel that are caused by long-term ingestion of fluoride during the time teeth are forming.
6. Infants who consume formula made with fluoridated tap water may consume up to 1,200 micrograms of fluoride, or about 100 times more than the recommended amounts.
7. The fluoride supplements sometimes prescribed to those who are not drinking fluoridated water have not been approved by the US Food and Drug Administration (FDA) for the prevention of tooth decay.
8. Water fluoridation is a form of mass medication that denies you the right to informed consent.
Many European nations have rejected fluoride for the very reason that delivering medication via the water supply would be inappropriate.
9. It is now widely recognized that fluoride’s only justifiable benefit comes from topical contact with teeth, which even the US Centers for Disease Control and Prevention (CDC) has acknowledged. Adding it to water and pills, which are swallowed, offers little, if any, benefit to your teeth.
10. Fluoride toxicity is exacerbated by conditions that occur much more frequently in low-income areas.

…Fructose, not fat, has a linear relationship with the U.S. obesity epidemic.

The incidence of overweight and obese individuals, shown by the National Health and Nutrition Examination Surveys (NHANES), has a striking relationship to fructose consumption in the United States. According to a USDA’s data below, total sugar and fructose consumption started to increase sharply in 1985, and reached a peak in 1999, which is congruent with the incidence of obesity. During 2000 through 2005, we see a slight drop in total sugar and fructose consumption, which is consistent with the leveling off of obesity rates during that same period. This drop in sugar ads up to 10 pounds of total sugar, with fructose contributing six of those pounds.

Strength and power have a positive influence on muscle endurance

Mike Furci explains this fitness tidbit in his latest “Did you know . . ” column.

Fernando J. Naclerio and fellow researchers performed a study using 14 firefighters to determine the importance of strength and power on a muscular endurance test. The physical test the firefighters were to perform for a job entry requirement was a maximum repetition test on the flat barbell bench press with 40 kg in 40 seconds.

The subjects performed a progressive test of eight sets of two to three repetitions during the first part of the study. The first and second sets were performed using a low load of 25 percent to 45 percent. The first set was always performed with a lower load than the second, which was performed using 40 kg. As subsequent sets were performed, the load was increased. The third and fourth sets were performed with a moderate load of 50 percent to 65 percent of their one-rep maximum (1 RM); the firth and sixth sets were performed with 70 percent to 80 percent of 1 RM; the seventh and eighth sets were performed with 85 percent to 100 percent of 1 RM.

To prevent fatigue from being a factor, the second part of the study (which was the max rep test) was performed 72 hours after the first part. Researchers found the 1 RM to have the greatest degree of influence in the firefighter’s performance on the 40 kg max rep bench press test. Interestingly, the degree of power produced in the progressive test using 40 kg had no correlation with the subject’s ability in the max rep test.(J Strength Cond Res.2009;23(5):1482-1488)

We’ll be writing more about this, but don’t wait until the holidays are over to start working out. Imagine how much better you’ll feel over the holidays if you’ve already started (or improved) your fitness and health program. Sure, you’ll be drinking and eating more than usual if you’re like most people, but at least you won’t regress too far.
