I'm quite fascinated with bacteria these days. First, there was research that indicated that bacteria might cause autoimmune diseases like lupus, MS, and rheumatoid arthritis. Then it was the bacteria in red meat, then in eggs, that contributes to heart attacks. Then it's the bacteria in the stomach that differentiates fat mice from thin ones and the bacteria in stomachs that changes after a person has gastric-bypass surgery, not just the size of the stomach. Now, researches have perhaps found that it is bacteria that causes a almost half of back pain in people who have herniated discs.
I'm wondering if everything we know about health, disease, and even obesity will be totally overhauled in coming years. Wait til we learn that obesity is an epidemic because it is a bacterial infection that alters how people metabolize food. Perhaps it's no wonder that the modern American diet industry is so relatively ineffective. They're fighting the wrong thing. Same with cholesterol and heart attacks, MS, and perhaps other things like cancer.
Really amazing how little we really understand.
And yet another good reason to get dirty and avoid antibacterial soap and antibiotics except when absolutely necessary.
