Soy milk is an increasingly popular and healthy alternative to cow's milk. Soy milk is made by processing soy beans, and it contains all eight of the essential amino acids, so it's high in complete proteins. Here are some of the benefits of drinking soy milk.
1. Soy Milk Is Lactose Free
Lactose is a type of natural sugar found in cow's milk, as well as the milk of other animals. Many people are lactose intolerant, meaning their bodies have difficulty digesting lactose because they don't produce enough of the necessary enzyme lactose. But, soy milk doesn't contain lactose, because it's not made from cow or any other type of animal milk, but is manufactured by processing soy beans. Soy milk and other soy dairy products are a healthy alternative for those who suffer from lactose intolerance. Soy milk is also safe for those who are allergic to milk.
2. Soy Milk Is High in Protein
A serving of soy milk contains just as much complete protein as a serving of cow's milk. While soy milk naturally contains very little digestible calcium, manufacturers often fortify soy milk with digestible calcium.
The protein in soy milk is vegetable protein. Vegetable protein is known to prevent the loss of calcium in the urine, and can help protect your bones from osteoporosis.
3. Soy Milk is Good for Your Heart
Soy milk is low in saturated fats and cholesterol, so it's better for your heart than cow's milk. Soy milk and other soy products contain large amounts of polyunsaturated fats, which help lower blood cholesterol and trigylceride levels, and they're also rich in vitamins and minerals beneficial to heart and overall health.
4. Soy Milk Is High in Antioxidants
Soy milk is high in a type of antioxidant known as isoflavones. Not only do isoflavones protect your cells against the effects of aging, but they also help to lower cholesterol, prevent osteoporosis and ease menopause symptoms. Isoflavones also reduce your risk of breast, prostate and other reproductive cancers.
One serving of soy milk contains about 20 mg of isoflavones. Cow's milk contains no isoflavones at all.
5. Soy Milk Is Hormone Free
Because soy milk is manufactured from soy beans and not produced by an animal, it doesn't contain synthetic hormones and it doesn't contain natural hormones either. Cow's milk always contains hormones, whether the cows are given synthetic hormones or not. Even milk from cows not given synthetic hormones will contain the natural hormoens produced by the cow during lactation.
6. Soy Milk Is Casein Free
Casein is a type of protein found in cow's milk. Some people are allergic to casein, and those who suffer from Celiac's disease or gluten intolerance may also need to eat a casein free diet, since the chemical structure of casein is similar to that of gluten. Those with allergies or asthma may find that eating a casein free diet eases their symptoms and enhances immune function.
