Diary of Unknown Symptoms

Mystery of the Internal Vibration

Entry for December 28, 2007


I find it very weird that for the week I’m on vacation I haven’t had one day with cold hands. I’ve been fighting this now for weeks almost on a daily basis. So what’s the difference? There’s been a lot of talk recently about the effects of Bisphenol A and how it’s easily found in plastic water bottles. When I’m at work, I drink at least two litres of water a day with a store bought plastic water bottle. Since I’ve been on vacation, I haven’t been drinking any water. I drink mostly milk or juice from a mug.

Health Effects of Bisphenol A

Bisphenol A has low acute toxicity, with an oral LD50 of 3250 mg/kg in rats, but it is an endocrine disruptor. Low doses of bisphenol A can mimic the body’s own hormones, possibly causing negative health effects. There is thus concern that long term low dose exposure to bisphenol A may induce chronic toxicity in humans.

 

Drink your water in glass, not plastic

Plastic polycarbonate bottles such as Nalgene are still popular as drinking water bottles. However polycarbonate releases a chemical known as bisphenol A also know as BPA. Whereas plastic industry safety studies find no significant health effects from typical daily doses of bisphenol A, a full 90% of government studies found harmful health effects especially to children and expecting moms, but also for male sexuality and reproduction as well.

The problem is that bisphenol A acts as a “xenoestrogen,” which just means it’s like the female hormone estrogen, except for two things: 1) it’s foreign to the body, which is what “xeno” means, and 2) it is way more harmful than our natural estrogen for everyone, male and female. Breast cancers are much more of a risk in women who carry a high burden of xenoestrogens, and both sexes are subject to a huge range of other harmful health effects. The most far-reaching effects are birth defects and miscarriages. Another effect is a disruption of beta cell function in the pancreas, which creates a pre-diabetes type condition of high blood insulin and insulin resistance.

We have previously warned our readers never to leave a plastic water bottle on a hot car seat, because the phthalates used in the manufacture of plastics leach into the water that you then drink. Phthalates are another xenoestrogen. However, with the polycarbonate bottles it has been found that even at room temperature, bisphenol A leaches into the water, and more so with increased temperature. Also with repeated use of plastics, you may notice the fine line scratches that you see on an old plastic container. These increase the surface area exposed to the liquid inside and release more of the xenoestrogens into the water.
