BPA Free – Another Con Job?

Bisphenol A, aka BPA, has been implicated as an endocrine disruptor (affecting organs like your thyroid). In response, consumers have demanded that it be removed from products they use like hard plastic bottles. Over the past few years we’ve seen lots of stickers on these products proudly announce that they are ‘BPA Free!!!’ Many out there were happy to see this change.

For anyone who has listened to my lectures recently should remember that I warned the audience that this was likely to be nothing more than a con job. Did industry remove BPA from these products? Of course they did, doing anything less would have been lying. Were they being entirely honest? Heck no. No more BPA meant using BPS and BPF both of which I said were going to be just as bad.

This week, the journal¬†Environmental Health Perspectives released a pre-publication article saying that “Based on the current literature, BPS and BPF are as hormonally active as BPA, and have endocrine disrupting effects.” People in the plastics industry knew that these replacements for Bisphenol A were damaging to the endocrine system and if they claim they didn’t, then, frankly, they had their heads buried in the sand.

Critics of the position that toxicity from chemicals like BPA is not a major issue relating to human health are cut from the same cloth that claimed that cigarette smoking wasn’t a major cause of cancer. ‘Humans are not exposed to that much on a daily basis.’ goes the argument. Former Washington State governor, Dixie Lee Ray once said about the dangers of excessive radiation, “Everybody is exposed to radiation. A little bit more or a little bit less is of no consequence.” She even dismissed the negative health claims of the victims of the Hiroshima nuclear bomb.¬†

While this may seem over the top, it is the reality of what we as consumers face. Denial, delay, and slight of hand like the replacement of BPS and BPF for Bisphenol A. Instead of using BPA free plastic bottles, use glass or unlined metal containers. Your thyroid will thank you later.

Next time, I’ll continue the discussion on electrolytes and health.

Electrolytes – Balance is Key – Part 1

One of the most asked questions I am posed with is what supplement(s) would I want to take with me on a desert island and my answer always remains the same, electrolytes. There are others I would bring along depending on how many things I could take like Vitamin C, trace minerals and definitely B-Complex vitamins (wouldn’t want pellagra, beriberi or anemia).¬†Electrolytes though would always be number one.

A better question would be, ‘If you were dropped into a western, developed country, which supplement would you most want to make sure you have available?’ My answer would definitely be electrolytes with a bullet. The balance between two components of electrolytes, sodium and potassium, are as messed up in the Western diet as could be imagined.

Before we go much further, we need to define what electrolytes are. The standard definition is ‘any fluid that conducts, or has the ability to conduct electricity.’ Distilled water does not conduct electricity so would not be considered an electrolyte. Most soft drinks like Cola’s can be called an electrolyte but they are very poor conductors. So what about those sports drinks that are mass marketed? They probably are but they have lots of things in them like sugar and food colorings that are not helpful and for many people, detrimental. Your best choice for good electrolytes contain a balance of salts without sugars, additives or colorings.

Going back to the question of electrolytes and the Western diet, why you might ask, do I feel so strongly about its need? According to research, the average human needs 4,700 milligrams of potassium each day and 2,300 milligrams of sodium. In the typical Western diet, we get about 3,400 milligrams of sodium, slightly above recommendations, but the real kicker is that we only get about 2,400 milligrams of potassium, almost half of what we should be getting.

Today’s health monitors tell us that we need to reduce sodium intake because of its implication in coronary heart disease and in particular, high blood pressure (hypertension). Problem is, most studies done to measure the benefits of sodium reduction come up way short. Frankly, they tell us that reducing sodium intake really doesn’t do anything beneficial unless the amounts ingested are far greater than the average person takes in. Medicine seems to be stumped which astonishes me as they are missing the other side of the equation, potassium deficiency.

The DASH study is supposedly the be all reason why reducing sodium works so well but when you look at the diet, it dramatically increased potassium and magnesium, two of the minerals most deficient in the Western diet. While sodium reduction was the focus, I propose that it was the improved diets (vegetables, legumes and fruits) that helped the most as well of increasing the minerals we needed.

Every food we eat contains potassium so our bodies do not store this essential mineral very well. We don’t need to. Sodium on the other hand, is found in far fewer foods so we have evolved to retain this mineral. For millenium, salt, which is known as sodium chloride or NaCl, was an expensive commodity and not available to everyone. Today, it is loaded into almost every processed food and is a cheap condiment. Because of the West’s reliance on fast food for its convenience and easy availability, we are getting all the sodium we need. Potassium? Not so much.

Fruits, legumes and vegetables are abundant in potassium but that is what we tend to leave out of our diets. And we don’t do this for a few days a week, we do this year in and year out. Continuing to be deficient in potassium should be one of the main concerns in today’s Western diet but unfortunately it isn’t.

Next time, I will continue showing how important electrolyte balance is and what systems within the human body are most affected by imbalances.
