검증된 단계별 안내1
Understand the structure of a grain: A grain consists of three main parts - the bran (outer layer rich in fiber), the germ (nutrient-rich core containing vitamins and minerals), and the endosperm (starchy middle layer providing energy).
Learn the difference between whole grains and refined grains: Whole grains retain all three parts of the grain (bran, germ, and endosperm), while refined grains typically retain only the endosperm, removing the bran and germ during processing.
Identify the products mentioned: Brown rice and whole wheat bread are examples of whole grain products, meaning they retain all three parts of the grain.
Compare the options provided: Evaluate each option to determine which parts of the grain are retained in whole grain products. Whole grain products retain the bran, germ, and endosperm.
Conclude that the correct answer is 'Bran, germ, and endosperm,' as these are the parts retained in whole grain products like brown rice and whole wheat bread.
