What are all the components contained in breast milk?

Question

I have heard that breastmilk contains over 400 different components. What are these exactly?

Answer 1

There are a number of breast milk components that are extremely beneficial to babies’ development. Many of these cannot be found in formula.

* Immunoglobulins: All types of immunoglobulins are found in human milk. The highest concentration is found in colostrum, the pre-milk that is only available from the breast the first three to five days of the baby's life. Secretory IGA, a type of immunoglobulin that protects the ears, nose, throat, and the GI tract, is found in high amounts in breast milk throughout the first year. Breast milk levels of IGA against specific viruses and bacteria increase in response to a maternal exposure to these organisms.

* Lactoferrin: Lactoferrin is an iron-binding protein that is found in human milk, but is not available in formulas. It limits the availability of iron to bacteria in the intestines, and alters which healthy bacteria will thrive in the gut. It is found in the highest concentrations in colostrum, but persists throughout the entire first year. It has a direct antibiotic effect on bacteria such as staphylococci and E. coli.

* Lysozyme: Human breast milk contains lysozyme (a potent digestive ingredient) at a level thirty times higher than in any formula. While other components of breast milk vary widely between well-nourished and poorly nourished mothers, the amount of lysozyme is conserved, suggesting that it is very important. It has a strong influence on the type of bacteria that inhabit the intestinal tract.

* Growth Factors: Human breast milk specifically encourages the growth of lactobacillaceae, which are helpful bacteria that can inhibit many of the disease-causing gram-negative bacteria and parasites. There is a striking difference between the bacteria found in the guts of breast and formula-fed infants. Breast-fed infants have a level of lactobacillus that is typically 10 times greater than that of formula-fed infants.

* Allergic factors: The cows' milk protein used in most formulas is a foreign protein. When babies are exposed to non-human milk, they actually develop antibodies to the foreign protein.

* Carnitine: While carnitine is present in both breast milk and formula, the carnitine in breast milk has higher bioavailability. Breast-fed babies have significantly higher carnitine levels than their counterparts. Carnitine is necessary to make use of fatty acids as an energy source.

* DHA & ARA: The main long-chain fatty acids found in human milk are still not present in many formulas in the United States. These lipids are important structural components, particularly in the substance of the brain and the retina. Significantly different amounts of these ingredients have been found in the brains and retinas of breast-fed versus formula-fed infants.

or did you want the nutrient breakdown??

# energy (750 kcal / liter)

# Lipids (38 g / liter) - The main lipids found in human breast milk are the triacyl-glycerols, phospholipids, and fatty acids including essential fatty acids. Maternal diet does not affect the amount of fat in milk but does affect the types of fat. Cholesterol is present in breast milk (more information).

# Casein (2.5 g / liter) - protein - Casein or curds are proteins with low solubility which complex with calcium. These are present in breast milk in much lower concentration than in cow's milk.

# Whey (6.4 g / liter) - protein - the whey proteins are located in the clear liquid left behind when clotted milk stands. The largest components are alpha-lactalbumen, lactoferrin, lyzozyme, albumen and immunoglobulins.

# Nonprotein Nitrogen is used in amino acid synthesis and includes the nitrogen in urea, creatine, creatinine, uric acid and ammonia. Peptides, such as epidermal growth factor, somatomedin - C and insulin are also present in this fraction. Nucleotides such as cytidine monophosphate are derived from nucleic acids and play an important role in the immune system and protein synthesis.

# Lactose (70 g / liter) carbohydrate - Lactose is the major carbohydrate in breast milk. It is composed of galactose and glucose. Lactose concentration in breast milk increases over the duration of breastfeeding.

The amount of all of these substances (except lactose) varies with the time of day of the breast milk production, the woman producing the breast milk, and whether it is at the beginning or the end of the feeding. Fats and lipids are particularly high at the end of the feeding (hind milk)

Answer 2

All the vitamins the mother consumes are found in the milk. In addition, there's great amounts of Omega-3 fatty acids known as DHA. This is vital for brain development. Then ARA is an Omega-6 for body fat growth. There's the fat itself which is geared to how much a baby needs as is the protien content. Lots of water to hydrate the baby. And calcium which is taken from the woman's supply if not enough is consumed. This is why osteporosis is higher % in women than men (it begins in pregnancy). You'd have to read up what else there is to be precise.

Answer 3

The exact integrated properties of breast milk are not entirely understood, but the nutrient content after this period is relatively consistent and draws its ingredients from the mother's food supply. If that supply is found lacking, content is obtained from the mother's bodily stores. The exact composition of breast milk varies from day to day, depending on food consumption and environment, meaning that the ratio of water to fat fluctuates. Foremilk, the milk released at the beginning of a feed, is watery, low in fat and high in carbohydrates relative to the creamier hindmilk which is released as the feed progresses. The breast can never be truly "emptied" since milk production is a continuous biological process.

Though now it is almost universally prescribed, in the 1950s the practice of breastfeeding went through a period where it was out of vogue and the use of infant formula was considered superior to breast milk.

Some components of human breastmilk absent or deficient in pasteurized cow's milk (peptides such as cystine are destroyed by pasteurization):


Vitamins (fat and water soluble)
Minerals (especially Calcium, Phosphorus, and Zinc)
Lactose (aids in Calcium absorption)
Bile Salt Stimulated Lipase (aids in digestion of fats)
Cystine
Taurine
Secretory Immunoglobulin A (sIgA)
Lactoferrin (binds Iron and makes it unavailable to bacteria in the intestines)
Lysozyme (breaks cell walls of bacteria in the GI tract)
Bifidus Factor (creates more acidic stool, inhibits growth of harmful bacteria)
Polyunsaturated Fatty Acids
Essential Fatty Acids (Linoleic, Linolenic, Arachadonic)
Whey protein
HIV (if mother is HIV+)
Toxic chemicals (if mother is exposed)
DDT
PCB
Alcohol (if mother drinks)

If you want to make your breast bigger without surgery this is a good site you should visit http://breastenlargement.toptips.org

Breasts are one of the most defining and noticeable parts of a woman’s body. They have come to symbolize a lot about women, from our sensuality to our feminity, and are now an integral part of our image-conscious culture.

However, for many women, “breasts” is more of a taboo word, only used to describe a part of their body that they would rather change. With celebrities and other “successful” women all sculpting their bodies in the image that we all perceive to be “perfect”, it’s no wonder that big, full, round breasts are a growing desire for millions of women around the world.

The only problem for many women is that getting bigger, more “perfect” breasts is not just a case of saying your prayers every night…. it’s a struggle which is both risky and financially strenuous. Right now, you have two options to get bigger breasts. The first is to get some hideous, painful and risky implants which couldn’t make your body look less plastic. Or you could try and naturally make your breasts grow.

For many women, the first option is just out of the question. And unfortunately, there are a lot of women who don’t have access to any information about how to naturally make their breasts grow bigger. This is a travesty, because making your breasts grow is one of the easiest things if you do it right.

Answer 5

Nobody knows exactly how many there are, nor what each is, nor its effects. The number is merely an estimate.

However, *some* of the components are known. These include (in no particular order) proteins, fats, sugars, vitamins, minerals, antibodies, immunoglobulins, hormones, and water.

Lift up your left breast. It's printed right there along with the nutritional content values and the bar code.

God!...must I tell you people everything!????

Answer 8

I think radios and computers have components. Do you mean nutrients????

Answer 9

confusing step. search over google or bing. just that will help!
