Soy Milk vs. Formula

It is often required by parents to choose between different types of formulas while selecting formula to feed their babies. During the first year of a baby’s life, the rapid development and growth occurs, which does not occur at a different time in the life of a person. Infants in their first year are dependent on a sole source of nutrition; therefore, it must be the ideal source. This article describes the difference between milk and soy formulas.

Soy or Milk Formula, which is better?

1. General Introduction

  • Milk-based Formula

The standard infant formula is based on cow’s milk. Cow’s milk is modified for a baby by adjusting the levels of carbohydrates, protein and fat and fortify it with additional vitamins and minerals (the majority of both soy formulas and milk to 20 calories per ounce). In the last decade, the quality of the milk food for infants classic has improved to a large extent. However, researchers have not been able to emulate the unique qualities of breast milk, which is an ideal food for human babies.

  • Soy Formula

Soy protein is produced from soybeans and is also modified by adding vitamins, minerals and other nutrients to be used in infants formula. Although soy formulas are recommended by some health experts, others say that certain compounds such as amino acids are lacking in these formulas, these helps a baby to grow. Infants who exhibit allergies lactose (sugar found in cow’s milk) may have less sensitivity to the formula on the basis of soy protein. However, up to 50% of infants who are prone to allergies also develop a negative reaction of soybean and perhaps needs a hypoallergenic formula.

2. Soy Milk vs. Formula

The healthy food choice for babies is breast milk. However, if your baby needs formula, what should you choose? It is clear from the study that babies should not be fed soy formula until it is medically necessary for example in case of lactose intolerance in babies (if this condition is very rare).

According to many research in this field, it has been proven that soy formula can cause harm to developing the endocrine system of the baby. It is often linked to the development of ADHD in children. It can lead to early onset of early puberty and development of breast tissue in the development of girls. Soy formula may contain aluminum and manganese in levels that are dangerous to a developing child.

The use of soy formula has been severely restricted in countries like the UK, France, Israel and New Zealand because of the research evidence increasingly oriented towards adverse effects on health of the formula to soy milk. The American Academy of Pediatrics (AAP) also limited the use of soy formula. According to the AAP, human milk is the ideal food source for the development of babies. They say that if there are very few cases where the soy milk is medically indicated, more than 20% of milk powder sold in the United States is the formula to soy milk. The AAP recognizes that soy formulas have adverse effects on the health of babies. It contains phytoestrogens, which can also harm the developing babies.

Some Facts about Soy Formula:

  • There are some indications for the use of milk soy powder such as infants with galactosemia or rare condition characterized by an inherited deficiency of lactase and in situations where parents prefer a vegetarian diet for their baby.
  • In infants who documented allergy to cow’s milk protein, hydrolyzed protein formula that is widely expected to be used as a soy protein allergy is present in 10-14% of these infants.
  • Infants with acute gastroenteritis and previously good can thrive on the continued use of either breast milk or diluted cow’s milk formulas based upon rehydration. Soy formulas should be used in cases where the secondary lactose intolerance develops.
  • Soy formula is not advantageous for the cow’s milk-based formula when used to supplement the babies milk.
  • Premature babies are not recommended to be fed formulas based on soy protein.
  • Soy formula has not proven to be beneficial in either the prevention or management of colic or irritability in infants.
  • Infants with enteropathy or enterocolitis induced by cow milk protein should not be fed to the soy-based formula as these infants are often susceptible to soy protein. These children should be fed two hydrolyzed protein or amino acids obtained by synthesis.
  • It has not been proven that the systematic soy-based formulas use prevents atopic disease in infants at high risk and healthy.


What other Types of Formulas?

There are different types of formula available to meet the needs of most babies. Some of them are:



Lactose-free formula It is often used in babies who are lactose intolerant. These formulas have lactose replaced by another type of sugar such as corn syrup.
Hydrolysed formula These types of powdered milk proteins are decomposed into smaller particles, which are easily digested by the infant. They are suitable for babies with allergies such as eczema or who have difficulty absorbing nutrients.
Formula for low birth weight and premature babies More calories and protein are present in these formulas. They also contain another type of fat which is easily absorbed, referred to as medium chain triglyceride or MCT.
Human Milk Fortifier The specific needs of breast-fed babies are satisfied with this product. Some of these products are mixed with breast milk and some are powered alternative to breast milk.
Metabolic Formula Babies suffering from diseases that require specialized nutrition that may require metabolic formula.
Other formulas Alternatives: New formulas are manufactured and marketed to help relieve the symptoms of baby colic and reflux. The protein content in these formula is very similar to breast milk and their composition varies slightly from regular formulas.
