高纤维全麦食品也有不健康的一面：植酸会妨碍钙吸收（转）

High-fiber foods contain phytates, which prevent the body from absorbing calcium in other foods. 高纤维食品含有植酸，会阻碍身体吸收其他食品中的钙

Eating a high-fiber, whole-wheat cereal with milk, macaroni and cheese, or drinking a tall, cold glass of milk with Boston baked beans and hot dogs may be great-tasting combinations, but they do not boost bone-building nutrition.

Phytates found in whole-grains, legumes (dried beans), nuts and soy products bind the calcium of other foods eaten when they are eaten at the same time. When calcium is bound, the body cannot use it.

富含植酸的食品包括全麦、干燥的小扁豆，坚果和黄豆制品等，它们会把其他食物中的钙与植酸捆绑在一起，这样人体就无法利用那些食物中的钙。
