Today’s generation of children could aptly be called Generation A where the “A” stands for allergies. Food intolerances and of all kinds are rampant with the very first frequently becoming apparent when a formula-fed infant demonstrates an allergy to commercial milk-based formula. The typical recommendation by a conventional doctor in this case? Put baby on a soy formula such as Isomil or ProSobee immediately.
About 25% of American babies are fed soy infant formula according to the website of Dr. Sears.
Elemental infant formula might also be suggested, but these are usually reserved for preterm infants and those with specific medical problems such as severe allergies to both milk and soy. Elemental formulas also tend to be foul-tasting compared with milk or soy-based formula and babies tend to reject them for this reason.
Many parents make the switch to soy formula in haste hoping to ease the digestive discomfort their child is experiencing on commercial milk formulas not realizing the full implications of their decision.
In some cases, parents may never even try a dairy formula at all if a milk allergy already runs in the family. There is no evidence that using soy formula reduces the risk of a dairy allergy later, however. For this reason, the Committee on Nutrition of the American Academy of Pediatrics recommends against the use of soy formula in infants who are potentially allergic to cow’s milk. A milk-based formula should still be the first choice even in those situations.
The Three Reasons Why Soy Formula is So Bad for Babies
The primary problems with soy protein found in non-dairy commercial formulas are threefold: trypsin inhibitors, phytic acid, and phytoestrogens.
Trypsin Inhibitors
These are proteins found in plentiful amounts in soybeans that inhibit digestion and absorption of nutrients. They are large in size and require the application of high heat for appreciable periods of time to neutralize.
The industrialized process of producing soy infant formula deactivates the majority of trypsin inhibitors. Unfortunately, some remain and even in low amounts, they have been found to prevent normal growth in rats. Given that a baby’s brain grows at its most rapid rate the first year of life, growing to about 75% percent of adult size (it is 25% of adult size at birth), even slight retardation of growth could be devastating to the development of the brain and nervous system.
Note that protease inhibitors in soy are also an issue, as they greatly hinder the digestion of protein. Potential harm to the pancreas is another grave risk.
Phytic Acid
Phytic acid is an organic acid, which like trypsin inhibitors, is present in large amounts in soybeans. Phytates are present in the outer portion of all seeds and block the absorption of critical minerals like calcium, magnesium, iron and particularly zinc. Phytic acid is also extremely irritating to the digestive tract.
Unlike other seeds, soybeans have extremely high amounts of a type of phytic acid. This anti-nutrient is particularly resistant to deactivation. Researchers testing soy formula in 1967 found that soy formula caused zinc deficiency in every single infant who received it. Again, this is due to the mineral blocking effect of phytates within the digestive system.
Zinc is known as the intelligence mineral because it is critical for the optimal development and functioning of the brain and nervous system. As a result, deficiency of this nutrient in infants at a time when the brain is growing at its most rapid rate could have lifelong implications and possibly reduce IQ.
Phytoestrogens or Isoflavones
Phytoestrogens represent the most serious problem with soy infant formula. These estrogen-like compounds have the potential to disrupt the baby’s hormonal system for life.
According to the Weston A. Price Foundation:
Toxicologists estimate that an infant exclusively fed soy formula receives the estrogenic equivalent of at least five birth control pills per day. By contrast, almost no phytoestrogens have been detected in dairy-based infant formula or in human milk, even when the mother consumes soy products. A recent study found that babies fed soy-based formula had 13,000 to 22,0000 times more isoflavones in their blood than babies fed milk-based formula.
Soy Formula Health Problems for Boys
Flooding of an infant boy’s bloodstream with female-like hormones has the potential to cause serious developmental problems at puberty. During the first few months of life, a baby boy has testosterone levels that could be as high as that of an adult male. This “testosterone surge” readies the baby boy’s hormonal system for puberty both for normal development of the sexual organs and also patterns of male behavior.
Could soy infant formula be responsible for the increasing problem of boys where physical maturation is delayed or even completely absent with retarded development of the sexual organs?
Soy Formula Health Problems for Girls
Baby girls fed soy infant formula may suffer negative hormonal impact as well from early soy exposure. In a 2011 published study, time-to-menarche was assessed in nearly 3,000 girls.
Those girls identified as early soy-fed via soy infant formula had a 25% increased risk of menarche specifically in early adolescence.
Early sexual development in girls can herald serious problems with the reproductive system later in life such as unexplained infertility and breast cancer.
Research from 2012 published in Biology of Reproduction’s Papers-in-Press describes the effects of plant estrogens found in soy on the mouse oviduct. The study was specifically designed to model the effects of soy-based baby formula on human infants. The results of the study suggest that exposure to estrogenic chemicals in the womb or during childhood has the potential to negatively affect a woman’s fertility as an adult.
Organic Soy Formula No Protection from Soy Dangers
Some parents mistakenly believe that genetically modified soy is the main problem and that buying organic soy formula is protective for their infant.
Nothing could be further from the truth. While organic soy formula does indeed provide a better quality source of soy, organic soy still has the same problems as GMO soy. Trypsin and protease inhibitors, high levels of phytic acid, and large amounts of hormone-disrupting plant estrogens can devastate the baby’s digestive development and hormones potentially for life!
Healthy Options to Soy Formula
Parents wishing to provide the highest quality formula for their baby should breastfeeding not be an option should consider a homemade formula made from grass-fed raw cow milk.
If cow milk is a problem, goat milk formula can be tried instead. Goat milk has a slightly different fat composition and protein profile that is easier for some babies to digest. Please note that powdered goat milk is not recommended. The powdering process denatures the fragile proteins in goat milk. Powdered goat milk is not as nutritious as whole raw goat milk. Moreover, the chances are high that it will cause an allergenic response in the baby at some point.
If all dairy even if unprocessed and grass-fed is still problematic, a homemade nondairy formula based on homemade bone broth can be utilized instead.
Thousands of mothers have successfully used these homemade formulas with their babies in recent decades with excellent results!
Weaning after Formula
One more point of note. When your child is ready to be weaned off homemade formula at one year old, skip the soymilk! Soy as a food or beverage is not any more appropriate for toddlers than it is for babies! If your child is allergic to raw milk from pastured animals (best choice), wean him/her onto a nutritious milk substitute instead.

my son had sever milk protein allergy and had on NEOCATE amino acid based formula for 3 years .he allergy is over now he take normal diet but his growth is very slow .he is 6 years
old with a weight of 17 kg and height just 105cm around 3 feet 5 inches. He had a good health when on neocate.is it due to neocate that he is not growing like a normal kid.plz guide.
Interesting…from Dr. Sears website, it appears that they do NOT recommend soy formula unless otherwise instructed by one’s pediatrician: http://www.askdrsears.com/topics/feeding-eating/bottle-feeding/soy-formulas
to all you mothers out there…PLEASE do not believe EVERYTHING you read on the internet. just because some random person who you dont even know say this and that doesnt mean its true lol you know your kid best. while some information is true, biased article info like this can EXAGGERATE the facts.
pls do your own research and dont listen to everything that you read on the internet. internet is the most unreliable place you can go to regarding parenting/kids.
and think of this, millions of dollars in research and development for these formulas throughout decades…and you think they wouldnt think of these factors? you think it would still be in the market if ALL kids who takes these formulas turn out to have infertility, slow mental growth and some other things? remember not every child is the same. some kids are just unlucky to have these results.
OK I have a nephew who is now 5 so he’s gotten over this condition but when he was born he was born with lactose intolerance (his mommy is lactose intolerant). It took them 3 months to figure it out he wouldnt keep anything down and she couldn’t produce milk whatsoever so she tried soy milk formula and it worked he stopped puking and he was able to gain the weight he was supposed to. He has not develop any other allergies so I’m sorry but in her situation soy was best for him.
My son had to go on soy formula after he was born (just hours after his birth) because he kept throwing up the milk and I wasn’t producing any milk. He was diagnosed with Hypothyroidism and put on medication before he was two years old. He’s 11.5 now and is still taking a thyroid med. He’s average height for his age now but he was on target in the 75% for his age group at 18mths. I’m not sure if the soy milk had anything to do with his thyroid and height issues but I’m just happy that his doctor noticed he wasn’t growing like he should have when he was 18mths old.
My son was put on Whysoy and then Carabel due to reflux but then he and a few others also put on these formulas all have ADHD could being on this have given them this?
The article fails to mention that petrochemical based xenoestrogens, (excluding phytoestrogens) are the likely culprit responsible for women (and fish and everything else exposed) suffering negative hormonal impact related to estrogenic compounds. Phytoestrogens, including resveratrol, have documented positive impacts on cellular health. Phytoestrogens have been around for millions of years and our bodies and genome know what they are and what to do with them. On the other hand, plastic, now ubiquitous, leaches BPA and other estrogenic compounds which our bodies do not process well because they are unknown to our genome. These dangerous endocrine disruptors are responsible for the deleterious effects of estrogenics in the environment. Phytoestrogens may actually inhibit their effect by acting as an estrogen receptor site inhibitor. This was written by someone without the slightest notion of the complexity of estrogenic compounds in the environment.
This article is wrong. Soy phytoestrogens are epigenetic modulators that improve cellular longevity. Phytoestrogens are high affinity ER-beta receptor site modulators. This is a completely different biological pathway than ER-Alpha receptor site modulators like estradiol. Isn’t it odd that we would have evolved a completely different receptor site and pathway for phytoestrogens if it didn’t have some sort of alternative biological and evolutionary significance? See xenohormesis, S-Equol producers, superoxide dismutase induction via NRF2/Keap1. A number of studies indicate that infants fed soy formulas may benefit for life.
Anyone who feeds their Bub soy is an idiot. What happened to good old breast and cow milk. Soy tastes horrible apart from lacking basic nutrients.
I can’t say it was or wasn’t the formula, but I wish is known this 16 years ago. I didn’t produce breast milk. Everyone pushed soy! My daughter started puberty at 5, period at 8 and now has many symptoms of hormone issues!
