1.    Soy Milk

According to Medical News Today, soy milk is the most common alternative to cow’s milk. This alternative is made from soybeans. Though it may sound bland, you don’t need to worry about flavor. You can purchase fun varieties like chocolate and vanilla. You can even get it without flavoring if that’s more your speed. And it can be purchased with added vitamins and calcium. (Some brands boast more calcium than traditional cow’s milk.)

Soy milk may be beneficial when it comes to preventing heart disease because it contains isoflavones. Plus, it contains phytoestrogens, which some say may help keep hormone levels in check during menopause.

That said, there is one concern when it comes to soy milk. Soybeans are considered one of the "big eight" allergens. However, regular milk can be found on that list as well.

2.    Almond Milk

According to BodyBuilding.com, almond milk is a dairy-free option created from almonds. To make this milk, almonds are ground with water. The good thing about almond milk is that it is low in calories and often rich in vitamin E and antioxidants. However, almond milk is made with tree nuts, which is also one of the big eight allergens. So those who have nut allergies should steer clear of this option.

3.    Coconut Milk

Coconut milk has become a popular alternative to cow’s milk because of its consistency, which is much like whole milk. According to Medical News Today, this is a higher-fat option. One serving has about five grams of saturated fat, making this a choice to avoid for those who are looking for lower-fat options. Many people are said to use this option for baking, which makes it a front runner for enthusiastic cooks. Plus, it has more potassium than cow’s milk. But coconut milk is low in protein and has much less calcium than regular milk.
