Soy milk is a fluid that is derived from soybeans, and from this point of view is not really milk. However, it is referred to as milk for its use as a substitute of the original, and because it is close in nutritional value to cow's milk. While it seems to have been first used in the east, at present, the milk is growing in popularity all over the world. It comes as a salvation to those who are lactose intolerant or have a milk allergy, and thus need to refrain from cow's milk. However, the growing popularity of this milk also raises the debate between the two. The primary difference between the two is that the former comes from a plant, while the latter is an obtained from an animal. It is a popular opinion that soy milk has been discredited by the milk industry as it poses a huge threat to them. However, as educated individuals it is easy for us to assess the facts and make informed decisions. Cows Milk Cow's milk is full of nutrients and provides you with all the required amino acids. Let's take a detailed look at the nutrients in a cup of cow's milk. A cup of regular cow's milk contains 8 grams of protein and 12 grams of carbohydrate. This quantity completes 30% of our (adults) daily calcium needs, and about half of our vitamin B12 and riboflavin requirements. Cows milk is commonly fortified with vitamin D which helps the absorption of calcium and often, vitamin A as well. Cow's milk also contains a significant amount of fat. However, this can be dealt with by using low fat, skim milk, or fat-free versions. A component of milk that is known to cause digestive problems for many people is lactose, which is a primary carbohydrate. Lactose intolerant people are deficient in the lactase enzyme that the body employs while breaking down this milk sugar. Soy Milk A commonly used soy product, soy milk is made by soaking, grinding, and straining of soybeans. An important aspect of soy milk that is highly beneficial is that it provides an alternative to people who are lactose intolerant. For vegetarians and vegans who avoid cow's milk, it provides the perfect plant source replacement. As for its nutritional value, one cup of unfortified soy milk contains approximately 7 grams protein, 4 grams carbohydrate, 4½ grams fat, and no cholesterol. It contains small quantities of B vitamins, but is not a good source of B12 and calcium. To deal with these 'deficiencies' producers offer fortified versions, which include calcium and vitamins E, B12, and D, among other nutrients. Another beneficial aspect of soy milk is that it may help people reduce the risk for heart diseases. Soybean contain plant chemicals called isoflavones, which assist in the lowering of LDL ("bad" cholesterol). The recommended amount is about 25 grams of soy protein everyday. On an average, one cup of soy milk (varies from one brand to another) provides about 7-10 grams of protein. Women who are affected by breast cancer must make cautious use of soy protein, as some studies have reflected possible harm from the consumption of excess soy. Soy Milk or Cow Milk for Infants For those parents whose infants cannot tolerate cows milk, the choice is easy. However, if your baby can tolerate both equally well, then according to the American Academy of Pediatrics (AAP), cow's milk formula is still the next best thing to breast milk. It is recommended that parents give soy formula only to infants who cannot digest cow's milk or to those whose parents wish them to follow a vegan diet. Now that we've examined both soy milk as well as the cow milk, it is for you to decide which one you will use based on your personal preference and your health objectives.
