Lactose, the primary carbohydrate in cow's milk, will cause digestive problems for some people. The people are intolerant (intolerant) to the lactose enzyme deficiency caused by lactose, which is necessary to break down lactose.
This makes people intolerant to produce gas, bloating and diarrhea after eating some form of cow's milk products.
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 drink made from soybeans. Soy milk is also popular among vegetarians, because the basic ingredients derived from plants.
Today, more people are deliberately choosing soy milk instead of cow's milk because it offers health benefits. But the benefits of soy is still being debated, although it is generally accepted that soy milk contains a large number of compounds that are very healthy.
The debate of soy milk and cow's milk
The main difference between soy milk and cow's milk is the source, ie plants and animals.
As reported by the 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 milk is not a source of B12 and do not provide significant calcium intake.
Since the soy milk to cow's milk substitutes, the manufacturer has offered a version of the soy milk that has been enriched, with calcium, vitamin E, B12, vitamin D and other nutrients.
While cow's milk provides carbohydrates, vitamins, minerals, and fat. All cow 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 absorption of calcium, and vitamin A. Thus, cow's milk is considered as a complete meal.
The advantage of dairy cow milk
Dairy cows undergo a process of pasteurization, which is a process in which milk is heated, kills bacteria, enzymes and proteins that is not profitable.
Cow's milk is rich in enzymes and actually contains the 22 essential amino acids, including phosphate, is essential for calcium absorption.
Raw cow's milk or cow 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 the sources of non-meat. And also contains enzymes IgG (Immunoglobulin), vitamins A, B, and C.
Research also shows that the dairy cow milk also contains enzymes and antibodies that actually make the milk less susceptible to bacteria. Lipase is also present which helps 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 is irrefutable. However, many people who care about the comparison of measured soy milk to cow's milk.
Soy milk is high in protein, and because it is made from beans also contain fiber which is much higher than cow 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.
Soy milk is fat free. Soy milk has 2 percent less fat than cow's milk, but do not contain bad 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, Suu soy can reduce bad LDL cholesterol, whereas cow's milk increase LDL cholesterol levels. Soy milk also provides additional protection for 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) as compared with cow's milk. Soy milk also contains more magnesium, copper and manganese from cow's milk.
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 require 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.
The weakness of soy milk
The main drawback is the lack of soy milk contain calcium, which is only about a quarter of the calcium contained in cow's milk. 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.
Cow's milk has a fifth of grams of amino acids is more important than soy milk. Because one of the nine essential amino acids is methionine, this can be victory for lovers of cow's milk. Cow's milk contains twice as much methionine than soy milk.
Soy milk contains riboflavin, about 60 percent less than cow milk. Riboflavin is an essential vitamin, but is also found in grains, nutritional yeast, green leafy vegetables, beans, and wheat. Therefore, cow's milk is not the necessary resources for riboflavin for people who eat a balanced diet.
Women who have breast cancer may have to limit the intake of soy protein, because several studies have pointed to the potential dangers of consuming excess soy.
Another study published in the journal Human Reproduction, found that 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 types of milk is not given to infants under one year of age. Breastmilk is the food and beverage for infants, because all sources of nutrients needed for growth and development are contained in breast milk.
