Many people are switching to soy milk because of allergy to lactose, which is the main carbohydrate in cow milk. What are the advantages and disadvantages of each milk this?Lactose, the main carbohydrate in cow's milk, will cause digestive problems for some people. People who are intolerant (intolerant) to lactose by a deficiency of the enzyme lactose, which is necessary to break down lactose. This makes people intolerant to produce gas, bloating and diarrhea after eating some form of dairy cows.
Soy milk is a substitute for people who are allergic to cow's milk. Technically, soy milk is not milk as in cow's milk, but juice beverage made from soybeans. Soy milk is also popular among vegetarians, because the basic material of plant origin.
Today, more people are deliberately choosing soy milk instead of cow's milk for health benefits it offers. But the benefits of soy is still a debate, although it is generally accepted that soy milk contains a large number of compounds are very healthy.
The debate over soy milk and cow's milk
The main difference between soy milk and cow's milk is the source, ie plants and animals.
As quoted from SteadyHealth, Friday (14/05/2010), one cup of soy milk is not fortified (still pure, yet they were enriched) contains nearly 7 grams protein, 4 grams carbohydrates, 4.5 grams of fat and contain no cholesterol.
Although soy milk contains vitamin B, but this milk is not a source of B12 and does not provide significant calcium intake.
Since the soy milk made of cow's milk substitute, the producers have offered versions of soy milk that has been enriched, with calcium, vitamin E, B12, vitamin D and other nutrients.
While milk cow to provide carbohydrate, vitamins, minerals, and fats. All cow's milk contains 8 grams of protein and 12 grams of carbohydrate per cup. It is also a rich source of other nutrients.
One cup of cow's milk provides 30 percent of the daily calcium requirement of adults, and about 50 percent of vitamin B12 and riboflavin. Often fortified with vitamin D to facilitate calcium absorption, and also vitamin A. So the cow's milk is considered a complete food.
The advantage of dairy cow milk
Dairy cows experience the process of pasteurization, which is a process in which milk is heated, kills bacteria, enzymes and proteins are not profitable. Cow's milk is rich in enzymes and actually contains the 22 essential amino acids, including phosphate, which is essential for calcium absorption.
Raw cow's milk or perahan has many health benefits and is the best source of calcium. Milk is a source of vitamins, especially vitamin B12, which is an important vitamin that is hard to find from the sources of non-meat. And also contains enzymes IgG (Immunoglobulin), vitamins A, B and C.
Research also shows that the milk of dairy cows also contains enzymes and antibodies that actually make milk less susceptible to bacteria. Lipase is also present which aids digestion of fat. Another great benefit is that cow milk contains CLA (conjugated linoleic acid) or conjugated linoleic acid, which has been observed to fight cancer.
The advantages of soy milk
The health benefits of soy milk it is irrefutable. However, many people who care about the ratio of soy milk with cow's milk was measured. Soy milk is high in protein, and because it is made from peanuts also contain a much higher fiber than cow's milk.
The biggest benefit is the isoflavones from soy milk. These are chemicals that resemble the hormone estrogen. Isoflavones linked to health problems and is responsible for preventing many cancers, heart disease, osteoporosis and many other diseases.
Fat-free soy milk. Soy milk has 2 percent less fat than cow's milk, but do not contain cholesterol.
Because soy milk made from peanuts, milk contains about 9 times less saturated fat than cow milk. In addition, soy milk has 10 times more fatty acids than cow's milk, which is a healthy fat.
Cholesterol-free soy milk. In addition, soy can reduce Suu LDL cholesterol, whereas cow's milk increase LDL cholesterol levels. Soy milk also provides additional protection to the liver with phytochemicals, abundant in soy milk.
Soy milk contains four times more the amount of thiamin (vitamin B1) and almost twice the amount of niacin (vitamin B3) compared with cow's milk. Soy milk also contains more magnesium, copper and manganese from dairy cows.
Soy milk also contains 42 times the amount of manganese as well as cow's milk. Manganese is necessary for bone formation. People with anemia requires manganese for iron storage. Research has shown that men who drank two glasses of soy milk every day 70 percent lower prostate cancer. There are no similar findings about people who drink cow's milk.
Weaknesses soy milk
The major shortcoming is the lack of soy milk contain calcium, which is only about a quarter of the calcium contained in dairy cows. Many manufacturers of soy milk to add calcium to their products, but studies show that it is not as healthy as natural calcium.
The core nine amino acids in the protein necessary to sustain life, cow's milk and soy milk contain nearly identical amount.
Grams of cow's milk has the fifth amino acid is more important than soy milk. Because one of the nine essential amino acids is methionine, this may be a triumph for lovers of cow's milk. Cow's milk contains two times more methionine than soy milk.
Soy milk contains riboflavin, about 60 percent less than cow milk. Riboflavin is an essential vitamin, but also found in certain grains, nutritional yeast, green leafy vegetables, beans, and wheat. Therefore, instead of cow's milk for riboflavin resources necessary for people who eat a balanced diet.
Women who have breast cancer may need to limit the intake of soy protein, because several studies have pointed to possible dangers of consuming excess soy. Another study published in the journal Human Reproduction, found 41 million fewer sperm per milliliter of semen after eating just one serving of soy-containing foods every two days.
But keep in mind, both kinds of milk was not given to infants under the age of one year. Breast milk is the food and beverages for babies, because all sources of nutrients needed for growth and development is contained in breast milk.
