Grade one and three soybean oil, which is better?

Now edible oil is divided into four grades, grade one oil is said salad oil before.
The difference is that process: whether decolorization and deodorization.
The two are not good or bad.

Choose which grade of oil according to your own needs, and not simply judged by the quality grade of oil.

Grade one soybean oil have light color, high smoke point, no taste, fewer impurities, more pure, but at the same time less nutrients.
Grade three soybean oil has not been decolorized and deodorized, reducing possible contamination of clay and the loss of vitamin E, color depth, it retains some peculiar smell of soybean oil.
Although there are some so-called impurities, but retain more nutrients.

Both have strengths and weaknesses.
