Comparison of Human Milk and Formula

The following chart compares the composition of formula to that of human breast milk. Many mothers do not realize there is a difference between breast milk and formula. However, as you can see from the chart there are many differences between the two.

NUTRIENT FACTOR BREAST MILK CONTAINS FORMULA
CONTAINS
COMMENT

Fats
  • Rich in brain-building omega 3s, namely DHA and AA
  • Automatically adjusts to infant’s needs; levels decline as baby gets older
  • Rich in cholesterol
  • Nearly completely absorbed
  • Contains fat-digesting enzyme, lipase
  • No DHA
  • Doesn’t adjust to infant’s needs
  • No cholesterol
  • Not completely absorbed
  • No lipase
Fat is the most important nutrient in breastmilk; the absence of cholesterol and DHA, vital nutrients for growing brains and bodies, may predispose a child to adult heart and central nervous system diseases. Leftover, unabsorbed fat accounts for unpleasant smelling stools in formula-fed babies.

Protein
  • Soft, easily-digestible whey
  • More completely absorbed; higher in the milk of mothers who deliver preterm
  • Lactoferrin for intestinal health
  • Lysozyme, an antimicrobial
  • Rich in brain and body building protein components
  • Rich in growth factors
  • Contains sleep-inducing proteins
  • Harder-to-digest casein curds
  • Not completely absorbed, more waste, harder on kidneys
  • No lactoferrin, or only a trace
  • No lysozyme
  • Deficient or low in some brain-and body-building proteins
  • Deficient in growth factors
  • Does not contain as many sleep-inducing proteins.
Infants aren’t allergic to human milk protein.

Carbohdrates
  • Rich in lactose
  • Rich in oligosaccharides, which promote intestinal health
  • No lactose in some formulas
  • Deficient in oligosaccharides
Lactose is considered an important carbohydrate for brain development. Studies show the level of lactose in the milk of a species correlates with the size of the brain of that species.

Immune Boosters
  • Rich in living white blood cells, millions per feeding
  • Rich in immunoglobulins
  • No live white blood cells-or any other cells. Dead food has less immunological benefit.
  • Few immunoglobulins and most are the wrong kind
When mother is exposed to a germ, she makes antibodies to that germ and gives these antibodies to her infant via her milk.

Vitamins and Minerals
  • Better absorbed, especially iron, zinc, and calcium
  • Iron is 50 to 75 percent absorbed.
  • Contains more selenium (an antioxidant)
  • Not absorbed as well
  • Iron is 5 to 10 percent absorbed
  • Contains less selenium (an antioxidant)
Vitamins and minerals in breast milk enjoy a higher bioavailability-that is, a greater percentage is absorbed. To compensate, more is added to formula, which makes it harder to digest.

Enzymes and Hormones
  • Rich in digestive enzymes, such as lipase and amylase
  • Rich in many hormones: thyroid, prolactin, oxytocin, and more than fifteen others
  • Varies with mother’s diet
  • Processing kills digestive enzymes
  • Processing kills hormones, which are not human to begin with
  • Always tastes the same
Digestive enzymes promote intestinal health. Hormones contribute to the overall biochemical balance and well- being of baby.
By taking on the flavor of mother’s diet, breastmilk shapes the tastes of the child to family foods.

Cost
  • Around $600 a year in extra food for mother
  • Around $1,200 a year
  • Up to $2,500 a year for hypoallergenic formulas
  • Cost for bottles and other supplies
  • Lost income when baby is ill
