Bigu is a way of eating that helps you avoid grains. Grains are parts of some plants that contain starches, like wheat, oats, and rice. Bigu means not eating these grains, and instead eating other types of foods. Eating fewer grains can help you feel better, have more energy, and can prevent many health problems. To do Bigu, you can focus on eating whole foods like fruits, vegetables, nuts, and healthy proteins. Try to buy food that is as close to its natural state as possible, and stay away from processed foods that often contain grains. Eating this way can help you to feel better and lead to a healthier lifestyle.
