Food is largest source of exposure to BPA

Bisphenol A, or BPA, is a chemical additive that is used in many things but mainly in plastics and linings of food cans.  Up until a few years ago this was considered a harmless addition to our already high chemical exposure levels.  Then, it was found that exposure to this chemical is linked to serious side effects but you could avoid any consequences by not reusing that Poland Spring bottle, by not overheating your plastics in the microwave or by buying BPA free merchandise.  Now we are finding out that our largest exposure to BPA is our food itself.

BPA has been linked to breast cancer, heart disease, diabetes, male infertility and other health problems.  Recently a U.N. panel concluded that the BPA in the packaging of our foods is actually leaching into the food making our food the number one source of exposure.  This should not be surprising.  One only needs to see the aftermath of the oil spill in the gulf to see that chemicals can get everywhere given the opportunity.

Information is limited on BPA.  It certain amounts it poses threats to fetuses, infants and growing children.  No one is quite sure what it does to adults.  For me, that’s enough.  If you didn’t know if a gun was loaded, would you point it at someone and pull the trigger?  Hopefully not and this is similar.  Just because we don’t know if it’s dangerous and the government is unwilling to take a stand on it just yet, doesn’t mean it shouldn’t be eliminated from our food supply.

This is just another reason to eat an unprocessed, natural diet.  Because this exposure of BPA is coming from foods that are packaged it can be avoided to some degree.  Eat a diet that is high in healthy protein, fats and vegetables and fruits.  Stay away from the packaged food as much as possible. Not only will you avoid BPA but you’ll also get all the great benefits of a healthy diet!

Can What You Eat Cause Infertility?

Apparently, the answer is yes.  Recent research has shown that women who have celiac disease are much more likely to have trouble getting pregnant than women who are not gluten sensitive.

Celiac disease is a genetic disorder in which gluten, the main protein found in wheat, is not properly processed.  It causes an autoimmune reaction in the body leading to ulceration and inflammation in the gut.  Symptoms include diarrhea, gas, bloating and fatigue.  A person with celiac disease may be asymptomatic or may have very severe symptoms.  Although wheat is the main offender, gluten is also found in rye, barley and oats.

The reaction the body forms to gluten causes the lining of the small intestine to atrophy.  This problematic because this is the portion of the digestive tract that is most responsible for absorbing nutrients.  If you cannot absorb nutrients your body cannot thrive.

Women with untreated celiac disease are more likely to have problems getting pregnant.  They also will have higher incidences of miscarriage and premature births.  Believe it or not, men will also have issues with fertility if they have celiac disease.  There are also other problems associated with untreated celiac disease for women.  Dr. Sheila Crowe, a professor in the division of gastroenterology and hepatology in the department of medicine at the University of Virginia lists the following problems.

  • Later onset of menstruation
  • Earlier menopause
  • Secondary amenorrhea (a condition in which menses starts but then stops)

These menstrual problems cause a woman to ovulate less which results in a smaller chance of getting pregnant.  Men may also have trouble with fertility as mentioned above.

  • Abnormal sperm (reduced sperm count, altered shape, and reduced function)
  • Reduced testosterone levels

Dr. Crowe recommends that if you and your partner are having trouble getting pregnant, you should both be screened to see if celiac plays a role.  Remember, you may not have symptoms and still have celiac disease.  The test is a relatively simple blood test.  Be sure to continue to eat gluten throughout because if you go gluten free before the blood test it may not show up.  If the blood test comes back positive, a tissue biopsy may be performed to confirm the diagnosis.  The pathologist will look at the cellular lining of the small intestine to confirm that there is in fact atrophy.

Treatment for celiac is relatively simple.  Avoid gluten.  This is becoming more and more common place and grocery store chains are starting to carry more foods that are gluten free.  A simple diet change is enough to solve this problem.

Low Carb is Still the Way to Go

A large portion of carbohydrate products are made from grain.  The most common grain used is wheat and wheat contains large amounts of gluten.  I am huge proponent of low carbohydrate diets for overall health.  While celiac disease might cause auto-immune reactions that disrupt fertility, obesity is also a known risk factor for infertility.  Women who are obese are 43% less likely to conceive a child than normal weight or even overweight people. If you think about this in terms of evolution it makes sense.  A woman who is obese is less likely to survive child birth because of the strain it puts on the body.  It is not unreasonable to assume that the lower rates of pregnancy in obese women is some sort of protective measure, evolutionarily speaking.

Research has shown that low carbohydrate diets are more effective for losing weight and improving measurable health outcomes over the traditional low fat diet.  See our old post. If you are having trouble conceiving a child and you are significantly overweight you should try losing weight and possibly think about getting tested for celiac disease.  These are efforts you should undertake before considering fertility treatments.
