In this article, we are going to compare cashew milk and soy milk to see how they compare in many aspects including calories, nutritional content, taste, usage, effects on weight loss, and environment.

To make this comparison as fair as possible and get a realistic picture of how cashew and soy milk compare, we’ve used USDA’s date on products that are unsweetened and that aren’t fortified or that are minimally fortified if the completely unfortified product isn’t available.

Both cashew and soy milk are dairy-free, and therefore suitable for vegans and people that stick to a plant-based diet for a variety of reasons, but there are also many differences between these plant-based drinks.

Let’s see what cashew and soy drinks are, how they are produced, and finally how they compare in various ways.

What is Cashew Milk and How It’s Made?

The market for substitute milk is growing day by day. This sector, which was formerly dominated by almond, oat, and soy products, now has a range of plant-based milk, which each offers a different taste and unique nutritional advantages.

Cashew milk seems to be an ideal compromise, offering a low-calorie alternative with a creamier texture than most nut milk. It also is packed with minerals, healthy fats, vitamins, and other plant-based elements.

Cashew milk, which is available in sweetened and unsweetened variants, may substitute for cow’s milk in the majority of recipes.

Cashew milk has a range of beneficial lipids, proteins, minerals, and vitamins, including cashews themselves.

This incredibly nutritious beverage gets the majority of its content from unsaturated fatty acids, which are known to improve heart health and give a variety of other advantages.

In comparison to handmade cashew milk, commercial varieties are often enriched with additional minerals and vitamins and they contain greater quantities of certain components overall.

What is Soy Milk and How It’s Made?

Soy is a legume that originates from Asia and is very popular to be consumed today. Soy milk is a milk derivative made from soybeans.

Since it is plant-based and offers various health benefits, soy milk has an important place, especially in plant-based nutrition. It’s often used as a dairy-free alternative for coffee, breakfast oatmeal or cereals, rice puddings, baked goods, curries and so on.

Along with almond and oat milk, soy milk is one of the most popular plant-based nut milks.

Soy milk is prepared by combining soaked soybeans into the water and filtering off the particles to leave a clear, milk-like fluid. It is considered a whole soy food.

Both sweetened and unsweetened varieties are available.

Unsweetened variants are typically made up of solely filtered water and soybeans, while certain brands may additionally include vitamins, salt, or/and minerals.
