如果她以前以吃草（蔬菜）为主，肯定营养不良，各种病痛随之而来，也不奇怪。
这是她自己写的
Low-fat foods and vegetarian diets have a similar problem. They typically don’t provide a full range of nutrients, such as fat-soluble vitamins and even the fats themselves, and they lack many other compounds that help the body. One good example of this is the collagen we need for our joints, bones, and skin. Collagen loss may explain why I lost 1½ inches in height when I was a vegetarian. X-rays from the mid-1990s revealed that my vegetarian-fed spinal disks had frayed-looking edges and some compaction. Fatigue and apparent intolerance to vegetarian staples like soy beans finally drove me to add meats and eggs back into my diet in 1998. Within 5 years, I regained over an inch in height. More recent images of my spine show plumper disks with clear smooth edges.
