Corn and sweet potato are good medicines for promoting digestion and relaxing bowels. They have no fat, but also the calories and sugar needed for human activities. Moreover, corn can also prevent blood pressure from rising and reduce blood lipids. Sweet potato won't be fat, because it is also high in cellulose, but you can't eat too much. Corn is not suitable for people with type B blood, which will hinder fat decomposition.

Although potatoes are rustic and unremarkable, nutritionists advise dieters to eat potatoes without worrying about excess fat, because they only contain 0. 1% fat, which is far behind all hungry foods. Eating more potatoes every day can reduce fat intake, gradually metabolize excess fat and eliminate your worries.
