How does genetic engineering impact our food?

To put it plainly, genetically engineered (GE) foods, aka Genetically Modified Organisms (GMOs), are produced by using biotechnology to change the DNA of plants and animals by adding genes that are meant to accelerate and modify physical growth. Other ways our food becomes genetically altered is by overexposing crops to harmful pesticides and herbicides, and also by injecting animals with growth hormones.

As we pointed out last time, an obvious sign of genetic alteration is the antibiotic-resistant superbugs produced from over treating animals with antibiotics. And recent studies reveal an increase in super weeds, weeds that have grown resistant to commonly used herbicides and pesticides. In reaction, farmers are forced to use even more herbicides to combat the resistant weeds.

Extensive research reveals that harmful bacteria, chemicals and hormones are present in our food supply. Just Label It, an organization petitioning for the mandatory labeling of GE foods, estimates “…that 60%-70% of processed foods in U.S. grocery stores likely contain some GE material.”

What health risks does GE food pose to your child?

According to an excellent article in KIWI Magazine, Jeffrey Smith, author of Genetic Roulette, asserts that GMOs may greatly increase a child’s susceptibility to food allergies and autoimmune disorders because of children’s rapid growth and vulnerable immune systems. Children (compared to adults) are also likely to consume more GE foods like, corn and soy-based products, which puts them at even greater risk.

The author even touches on studies concerning babies who suffered negative reactions to breast milk. The possibility of a mother passing along GE molecules through her break milk is not a far-fetched concept, having recently reported on how what you eat greatly impacts your baby’s dietary tastes.

With ongoing research consistently drawing connections between diet and well-being, it is difficult to deny that we are only as healthy as the quality of food we put into our bodies. Additionally, the rise of superbugs and super weeds and the steep increase in childhood diagnoses like asthma, allergies and even autism makes it nearly impossible to turn a blind eye  to the potential dangers of genetically modified food.

How do you really know what you’re eating?

Maintaining a healthy diet for your child isn’t about filling them full of just any old fruits and vegetables. Knowing where your food comes from and how it is produced is critical.

The tricky thing about GMOs is that you don’t always know that you’re buying them, and the terms used on labels can be misleading. This is why organizations like Just Label It are fighting to have all GE foods labeled for accurate identification. A report from the Environmental Working Group helps to clarify some of the terms distributors use to promote sales, rather than awareness:

•            “Free range” doesn’t always mean animals were allowed to roam about freely

•            “Organic” = 95% of the ingredients are organic

•            “Made with organic ingredients” =  70% of the ingredients are organic

•            “100 percent organic” = must entirely contain organic ingredients

How can you protect your child from GMOs?

As KIWI Magazine details, there are ways you can limit your child’s exposure to GMOs.  Choose foods that are labeled as “100 percent organic”, “GMO-free”, and “USDA-certified organic.” You can also buy local; get to know organic farmers in your region to ensure you know where your food is coming from.

Overall, knowledge is the key. Stay up to date on the foods that are safe for you and your children to eat. Check out The True Food Shopper’s Guide to Avoiding GMOs published for FREE by the Center for Food Safety.

What is it about breast milk that provides such a boost to babies’ health?  Researchers are still working to answer this question.  We know that newborns take approximately 6 months to develop their immune system, making them incredibly vulnerable to disease.  During the first 10 days of life, a breastfed newborn ingests colostrum, a yellowish fluid known as “first milk,” and breast milk, both of which contain more infection-fighting white cells (also known as leukocytes) per milliliter than there are in the same volume of blood.  Macrophages and neutrophils are types of white blood cells that comprise approximately 90% of the leukocytic load, and their job is to engulf and absorb harmful bacteria.  The remaining 10% of these disease-fighting cells are lymphocytes, primarily T-cells and B-cells, which identify and eliminate invaders while developing antibodies in the newborn.  These lymphocytes produce Secretory IgA, which protect the newborn against environmental exposures and interferon, an antiviral substance.  Mother’s immunoglobulins (IgA, IgG, IgM and IgD) are also found in breast milk, and they protect babies from pathogens by coating the superficial layers of the intestines and other mucosal surfaces that serve as points of entry into baby’s body.²

Gut ecology is of special interest to those in the field of functional pediatrics because a healthy gut is typically indicative of over all health.  Research has shown that approximately 75-80% of immune function originates in the gastrointestinal tract.  Breastfed babies receive beneficial bacteria from the bifidus family that produce Gram-positive bacilli in the gut flora and discourage the multiplication of pathogens.  In contrast, babies who consume cow’s milk formula develop Gram-negative (potentially pathogenic) bacilli.  We know that complex sugars in breast milk help to feed the bifidus strains of beneficial bacteria in the infant’s gut.  Just last year researchers at UC Davis revealed that these same complex sugars are not digestible and mimic the surfaces of other cells.  This surface similarity encourages viruses and bacteria to dock with the indigestible complex sugars and not the infant’s gut cells, and this allows babies to flush out viruses and bacteria from their bodies!³

Breast milk has had approximately 200 million years of mammalian evolution to develop systems to protect the most vulnerable members of the species.  GetzWell Pediatrics supports the Surgeon General’s initiative and acknowledges that whenever possible “breast is best.”  We are a Breastfeeding Friendly Business and have a host of resources available to support breastfeeding mothers.  If families are unable to breastfeed, we are also prepared to provide individualized supplement programs to best protect their children.

A:  After the first few days of life when your baby has meconium bowel movements that are very dark and sticky, it’s normal for your newborn’s poop to begin to be very watery and seem like diarrhea.  Breast fed infants, in particular, have BMs that are loose and seedy and range in color from brown to mustard yellow to green.  A typical newborn’s poop looks a lot like grainy mustard–think Grey Poupon country style!

Q:  My newborn must have a cold because he keeps sneezing.

A:  It’s very unlikely that your baby is sick.  Newborns often sneeze quite a bit and we think of it as nature’s way of allowing your baby to blow his nose.  New babies have very small nasal passages and usually make a little bit of mucus which can produce some degree of nasal congestion.  This usually isn’t a problem, but because newborns don’t know they can breathe through their mouths, you may hear your newborn’s breathing and think it means he is having difficulty.  As long as your baby is feeding well, is content, doesn’t seem to be struggling to breathe or crying a lot (which forces babies to mouth breathe) he is likely just fine.

Q: We want to take our baby girl to a party but she is only 2 weeks old.  Is this OK?

A:  The immune system of a newborn is immature and the more people she is exposed to the greater the likelihood she may catch something which could cause her to become quite sick.  We generally stress being very careful regarding hand hygiene and potential exposure to germs for the first 60-90 days of life, when pediatricians consider a fever a sign that an infection may be serious.  Hand washing is the best way to prevent introducing illness-causing germs to your newborn; proper cleaning of your hands involves rubbing them together for 15 seconds (or 3 rounds of “Row Row Row Your Boat”) with good old soap and warm water or the use of an alcohol based hand sanitizer.

Q:  Which hand sanitizers are best?

A:  Generally we recommend an alcohol based product which is rated 0-2 on the Environmental Working Group (EWG) cosmetics database toxicity scale (http://www.cosmeticsdatabase.com) so that you’re sure to purchase something effective while avoiding highly toxic ingredients.  This is an important factor when considering what to buy for you and your baby.  EWG is a tremendous resource available to guide purchasing decisions.  Babies and small children have very thin skin and immature detoxification systems, and thus are vulnerable not only to what we feed them but also to what we use on their skin, what we clothe them in, and what they breathe.

Q:   Do I need to give my 2 month old baby Vitamin D drops?  There is not much sun in our San Francisco neighborhood and we spend most of our time indoors.

A:  Vitamin D is important to our health and many of us have insufficient levels due to lack of adequate sunlight exposure or supplementation.  The American Academy of Pediatrics (AAP) recommends all children receive a vitamin D supplement starting in the first few days of life because evidence has shown this could have life-long benefits.  Furthermore, because of the growing body of evidence that a pregnant woman’s vitamin D status is important to her developing fetus, the AAP has recommended that physicians caring for pregnant women consider vitamin D testing during pregnancy.

At GetzWell we test all new mothers’ vitamin D levels and often find they are lacking.  This is critical both for mothers’ health and directly impacts the breast feeding baby.  Once we have these results, we can tailor our recommendations to each mother and baby as part of our effort to optimize the health of our patients and families.
