No longer the exclusive domain of small health food stores, nondairy beverages—from soy to grain to nut milks—are readily available at your local supermarket. Each with its own distinct flavor, color, texture, and nutritional profile.
Soy milk was the first milk alternative to appear on supermarket shelves approximately 20 years ago, and it’s been the leader in nondairy beverages ever since. Soy milk, extracted from the whole soy bean, has a fat and protein content similar to 1 percent cow’s milk (see chart below) and is rich in plant sterols called phytoestrogens. Although the health benefits of soy are somewhat controversial, “Some studies show the phytoestrogen component in soy milk may help protect bone health and prevent bone loss,” says Kelly Morrow, M.S., R.D., adjunct faculty member in nutrition at Bastyr University in Kenmore, Washington.
Flavors such as chocolate soy may sound tempting, but be aware: added sweeteners also up the calorie count. Since the flavor and consistency of even plain soy milk varies from brand to brand, experiment to find your favorite. And, if possible, always choose organic to avoid pesticide residues and genetically modified organisms (GMOs).
Of the grain milks, rice milk, with its light, sweet taste is a favorite among consumers. Particularly appealing to people who suffer from food allergies (since rice is often well-tolerated over many other options), rice milk is naturally low in fat, but also low in protein, and high in carbohydrates/sugar, with over three times the amount found in unflavored soy or almond milk.
Other grain milk options include fiber-rich oat milk and multi-grain blends. These milks are higher in protein than rice milk, but have a similar carbohydrate count, also making them high in overall calories.
“One of the problems with some of the nondairy milks is the sugar [carbohydrate] content,” Morrow says. “Think of it this way: each 5 grams of carbohydrate equals 1 teaspoon of sugar. Rice milk and certain other milks can have as much as 30 grams of carbohydrates per cup. For comparison, cow’s milk has about 12 grams per cup.” Additionally, the low protein content is of particular concern for growing children and adolescents, Morrow warns, and no nondairy product should ever be used to replace breast milk or infant formula.
Almond milk, the king of the nut milks, is low in overall calories, a rich source of heart-healthy monounsaturated fat, and has a delicate, nutty flavor. Almonds are naturally high in calcium and vitamin E, but lose their nutritional punch when processed and diluted to make milk. To up its nutrient profile, almond milk is usually fortified with vitamins and calcium.
