Which plant-based milk is best if you avoid cow’s milk? Nutritionists have the answer

In recent years, plant-based milks have become a popular alternative to cow’s milk, with options ranging from almond to oat, rice to coconut. Each variety brings its own unique taste and nutritional profile, catering to different dietary needs and preferences. Whether you’re looking for something rich in protein, easy to digest, or full of fiber, the choices can seem endless. However, there’s one plant-based milk that stands out for its balanced nutritional profile and excellent digestibility—soy milk.

According to nutritionists, soy milk is one of the best plant-based alternatives, offering a complete protein. What does this mean? Simply put, soy milk contains all nine essential amino acids that our bodies cannot produce on their own. As nutritionist Celine Thompson explains, “It’s one of the best plant-based alternatives because the ingredient is a complete protein.”

Not only does it provide these essential amino acids, but it also has protein content comparable to cow’s milk, about 7 to 9 grams per serving—far more than almond or rice milk, which only offer about 1 gram per serving. This makes soy milk a great option for those looking to get enough protein without relying on animal products.

Why Fortified Soy Milk Is a Must

While soy milk is a nutritional powerhouse, it’s important to choose fortified soy milk—the kind that has added calcium, vitamin D, and often vitamin B12. This fortification brings the profile of soy milk closer to that of cow’s milk, especially when it comes to calcium and vitamin D intake. Amy Brownstein, a registered dietitian, points out that “fortified soy milk is designed to provide a nutrition profile that mirrors cow’s milk, ensuring you get the nutrients that are commonly found in dairy.”

If you’re looking to switch to soy milk, make sure it’s enriched to help ensure you’re getting the right amount of calcium and vitamins that support bone health and overall well-being.

Caution with Soy Milk: Moderation is Key

Despite its benefits, there are some considerations when consuming soy milk. Nutritionist Anne Guillot cautions about the isoflavones in soy milk, which are plant compounds that mimic the action of estrogen in the body. While no definitive recommendations have been made about isoflavones, Guillot suggests that “it’s best to consume no more than a quarter of a liter of soy milk a day” to avoid any potential long-term effects.

Moreover, while soy milk is rich in protein, it’s relatively low in calcium compared to cow’s milk, so it should not be relied upon as a sole source of calcium. If you’re considering switching, it’s important to balance your diet with other calcium-rich foods or supplements to ensure you’re meeting your nutritional needs.

Conclusion: The Best Choice for You

If you’re avoiding cow’s milk, soy milk offers a compelling option, especially when fortified. It provides a substantial amount of protein, essential amino acids, and is the most nutritionally complete option in the plant-based milk category. However, moderation is important, especially if you’re concerned about isoflavones, and you should always choose a fortified version to ensure you’re getting adequate calcium and vitamins.

As with any dietary choice, the key is to balance it with other nutrient-rich foods and enjoy a variety of plant-based milks to meet your nutritional goals. Whether you’re looking to improve your digestion, boost protein intake, or just try something new, soy milk might be a great addition to your diet.
