Knowledge | Preparing for a Healthy Pregnancy: Reduce Toxin Exposure and Adjust Your Lifestyle Before Conception


Are You Planning to Welcome a Baby?

Improving your health and reducing potential toxin exposure before pregnancy are important foundations for a healthy pregnancy. The following expert recommendations provide a detailed preconception guide for families planning a pregnancy.

Key Foundations for Preconception Health

Joel Evans, MD, founder of the Center for Women’s Health in Stamford and author of The Whole Pregnancy Handbook, said: “Being in the best possible health is the first step toward having a healthy baby.” This includes:


Do not smoke or drink alcohol, and limit caffeine.


Maintain a healthy weight and manage chronic conditions such as diabetes.


Exercise for 30 minutes each day.


Eat a balanced diet with plenty of fruit, vegetables, and whole grains.


Schedule a preconception consultation and tell your doctor about your diet, lifestyle, medications, supplements, family history, and personal health concerns. The doctor can assess your overall health and recommend any needed vaccinations.


Folic Acid: Supporting the Baby’s Brain and Nervous System

The American College of Obstetricians and Gynecologists (ACOG) recommends that all women of reproductive age take 400 micrograms of folic acid daily.

Folic acid can significantly reduce the risk of neural tube defects such as spina bifida, which often develop before a woman knows she is pregnant.


Foods rich in folate include fortified cereals, beans, citrus fruit, spinach, and asparagus. Diet alone often does not provide the recommended amount, so a multivitamin containing folic acid is advised.


Drinking Water Safety: Do Not Overlook Heavy Metals

Most household drinking water comes from municipal systems and is generally safe, but experts note:

Lead pipes or lead solder in copper plumbing can allow heavy metals to leach into water.


High lead exposure is associated with:


Increased risks of miscarriage and preterm birth.


Low birth weight and delayed neurodevelopment.


You can request a water quality report from the local water utility or contact the health department for lead testing. If needed, install an NSF International-certified filter to remove lead and other contaminants.


Fish and Mercury: Choosing Seafood Wisely

Fish provides protein and omega-3 fatty acids that are important for fetal brain and vision development. However, some large fish, including shark, swordfish, marlin, and king mackerel, contain high mercury levels and should be avoided.


The U.S. FDA and EPA recommend:


Avoid high-mercury fish.


Eat low-mercury fish 2 times a week, no more than 340 grams total, such as shrimp, clams, salmon, snapper, catfish, and canned light tuna.


Freshwater fish caught in lakes or rivers may contain more mercury. Consult local fish advisories or the Environmental Defense Fund Seafood Selector.


Pesticide Risks and Organic Food

“Some pesticide exposures have established causal links with miscarriage, fertility problems, and abnormal fetal development,” said Ted Schettler, MD, science director of the Science and Environmental Health Network.


Recommendations:


Use natural pest-control methods in the home and garden when possible and consult the EPA’s integrated pest management guidance.


Prioritize organic produce, especially items on the EWG Dirty Dozen (12) list.


Keep children away from outdoor areas while pesticides are being applied.


Household Cleaners, Plastics, and Dry Cleaning

Some conventional cleaning products contain volatile solvents, chlorine, or ammonia that may be harmful during pregnancy. Consider natural alternatives or homemade cleaners:


Baking soda can replace powdered cleansers.


A vinegar-and-water solution can clean countertops and glass.


Experts also advise:


Do not microwave food in plastic containers or under plastic wrap. Use glassware to reduce phthalate exposure.


Handle dry-cleaned clothing carefully: the traditional dry-cleaning solvent perchloroethylene (perc) can cross the placenta and enter the fetus or breast milk.


If dry cleaning is necessary, air clothing outdoors for 48 hours until the odor has dissipated before bringing it inside.


Renovations, New Furniture, and Toxins During Nesting

During preconception and early pregnancy, take particular care with formaldehyde, benzene, and other gases released by renovation materials.

Important considerations:


Homes built before 1978 may contain lead paint, which should be removed by professionals.


Avoid furniture, carpets, and paint with strong odors. Choose low- or no-VOC products.


Consider used or solid-wood furniture instead of new composite-wood products.


“A general rule during pregnancy or preconception is to avoid anything with a harsh smell,” said Kimberly Rider, designer and author of Organic Baby.


Male Preconception Health Also Matters

Prospective fathers should not overlook their own preconception health.

According to the U.S. National Institute for Occupational Safety and Health (NIOSH), the following exposures may affect sperm quality and count and may even increase miscarriage risk:


Pesticides, fertilizers, and heavy metals such as lead, mercury, and nickel.


Radioactive materials, glycol ethers, benzene, and petrochemicals.


Perchloroethylene and other dry-cleaning chemicals.


Men should also consider a preconception consultation, improve their lifestyle, and reduce toxin exposure to help create a healthier environment for pregnancy.
