Almond, hemp, oat, soy, and cow's milk: Which is best?

The number of people choosing nondairy, plant-based alternatives to cow's milk appears to be growing. So, how do these different milks compare nutritionally? Research from 2018 says that eating and drinking milk that comes from cows has been falling, with interest in alternative milks rising.

One of the main medical reasons why people choose plant-based milk products is to avoid symptoms of lactose intolerance or a cow milk protein allergy. Doctors estimate the incidence of this allergy is 2 to 5% in children under 3 years old. The incidence is lower in adults.
Some people may also choose plant-based milk products because they believe they are more sustainable, ethical, or healthful options compared to cow's milk.

Almond milk is one of the most widely consumed plant-based milk variety in North America, the European Union, and Australia. Researchers have suggested that almond milk is an effective alternative for children and adults who suffer with allergies or intolerances to milk. Compared to cow's milk, almond milk has less saturated fat and more unsaturated fats. The healthful fats in almond milk may help people lose weight and keep it off. Almond milk is low in calories and protein, which may not be suitable for all people, especially children.

Some manufacturers add calcium to almond milk to better resemble the nutritional content in cow's milk. People may not be able to absorb as much of this calcium as they would from dairy, so they should be sure to consume plenty of other calcium sources, such as dark green vegetables. Almond milk is available in flavored varieties. Some of these products have added sugar to extend the shelf life and improve the flavor and texture.

Unflavored hemp beverages are also low in calories and protein compared with cow's milk. There is, however, more protein in hemp beverages than in almond milk. Hemp seeds are also high in polyunsaturated fats, similarly to almond milk. Research shows that replacing saturated fats with these more healthful fats can help lower a person's overall cholesterol.
