Simple Creamy Sweet Potato Soup & About Soy Milk


Today I introduce you to Simple Creamy Sweet Potato Soup. This is a vegan and gluten-free dish because I use soy milk and don’t use cheese. But the consistency is perfect and the taste is divine. This is the best homemade soup!! (For the final presentation I drizzled some spinach puree.)


The reason I use soy milk is that I wanted to add protein to the soup. I used regular milk for my cooking when I lived in Japan. However I have used soy milk a lot in my diet since I moved to the US because there are fewer opportunities to get soy nutrients here. When I was in Japan, I had Natto, which is fermented soybeans, miso soup which is also fermented soybeans with salt and koji (the fungus Aspergillus oryzae) and used soy sauce for my cooking everyday, and I frequently had tofu dishes and soybean dishes. So I didn’t need to get nutrition from soy milk.

I want to say that soy milk is not milk. It is actually soybeans and water. But now there are many flavors of soy milk products which contain many additives to make it tasty. I think it’s better to drink these soy milk products than to drink sweet soda or sweet fatty beverages. If you don’t like these additives, you can choose Eden Organic Soymilk Unsweetened which has only two ingredients, soybeans and water. It has more of a soybean taste, but it is very healthy!

Now you can drink a glass of pure, unflavored soy milk per day because it’s not milk but just soybeans and water as I said. It is not good, however, to drink soy milk heavily like water. As I sometimes mention on the blog, we need to eat well-balanced meals to be healthier. For example egg is a highly nutritious food but we can’t live by eating only eggs because they don’t contain fiber and vitamin C. It could make you unhealthy if you ate only eggs. My point is you can’t eat huge amounts of soy even if it’s a healthy ingredient.

There are many articles that tell us that soy is a danger. If you ask me, you have to know “Appropriate quantities”. In Asia we eat large amounts of soy food and mostly live long and healthy lives. So how can we eat soy products and be healthy without risks!? Eat small portions of several kinds of food at each meal, which gives you a well-balanced meal. Read also You can Eat Anything You Want! But…

I use soy milk only for cooking soup or for my cereal about twice a week. I have 1/4 pack (3oz.) of tofu twice a week, miso soup every other day and use soy sauce for my cooking everyday. And I am totally healthy!!


My suggestion is to use several kinds of milk substitutes wisely in your meal. You can use any kind of milk for this recipe if you want but I highly recommend to use soy milk for cooking because that makes your dish nutritious and delicious!! If you can, try to use unsweetened soy milk which contains only soybeans and water for cooking. It’s very healthy!!!

The recipe is very easy!
