I am personally of the opinion (based upon some light research as well as intuition) that fluoridation of public water is a money-making scam by government contract seeking dudes at best (called “rent seeking” in economics), and very possibly a mechanism to make people docile and infertile, at worst.
Somebody once said: “Even if fluoride is so great for teeth, why would you want to drink it? You don’t swallow soap to clean your body.” That makes a lot of sense: in toothpaste is one thing, but constant digestion of it is dubious and maybe outright malicious.
I’m very uneducated about any issues with radio waves, although I have repeatedly heard that it’s best to keep high-frequency transmitters (like Wi-fi chips or cell phones) several feet away from your body. Because this is very easy for me to do, I just do that, and haven’t bothered researching it much beyond that.
So while I can’t offer too much on those two topics, there is one area that I do feel very knowledgeable and can say has changed my health dramatically: diet. I strongly encourage people to (a) get lots of saturated fats (natural fats in meat, eggs, butter, whole milk, etc.) because saturated fat is the foundation for all of our hormones. Part of the reason so many are infertile and listless today is because meat consumption has plummeted and so one’s body doesn’t have the good fats (saturated fats) for production of testosterone, HGH, pregnenolone, etc., etc. I begin most every morning with eggs and ten strips of bacon, and I eat tons of more fat throughout the day, and I am leaner than ever. I average about 500% the U.S. government’s daily allowance of fat…and my blood pressure and weight are awesome. All of the “low fat” stuff is total crap.
On the flip side (b)…avoid grains and sugars. When you’re consuming these, your metabolism reroutes to burn sugar for fuel instead of fat, and so your body just stores and stores fat. They also increase inflammation and have other deleterious effects on metabolism. If you stay under 150 carbs per day on average (certainly, feel free to indulge on the special occasion) and get your saturated fats, you’ll be amazed at how much your thinking clears up and your body firms up.
