STEP 1/5
Prepare sweet potatoes.
STEP 2/5
Sweet potato peel is also nutritious, so please pay attention to cleaning so that you can eat the peel. I washed it with calcium powder, an eco-friendly detergent, but if you don't have it, I wash it with vinegar, wipe it once with a vegetable sponge, and rinse it several times to remove moisture.
STEP 3/5
If you add dried kelp when steaming sweet potatoes, the salt of the kelp increases the boiling point, making the sweet potatoes ripen quickly.
STEP 4/5
Put a stainless steel bowl in the pot in the middle of the pot and put the sweet potatoes. Add kelp pieces and add water to half of the sweet potato and cook with the lid closed.
STEP 5/5
Boil until water is completely in a stainless steel bowl. It took about 30 minutes.
Sweet potatoes are a representative alkaline food because they contain beta-carotene and vitamin C, and in particular, they were selected as the three major red-yellow vegetables that prevent lung cancer. Oriental medicine has the effect of strengthening the spleen and stomach, relaxing the blood, and warming the five intestines. Fiber improves bowel movements and is a good ingredient for diet. However, sweet potatoes have different blood sugar levels (GI) between steamed and roasted sweet potatoes. The blood sugar index is a measure of the rate at which blood sugar rises after eating food, ranging from 0 to 100. Foods with a high blood sugar index quickly raise blood sugar and cause excessive insulin, which can lead to accumulation of body fat and promote obesity.
