自元月，安娜开始吃无谷蛋白食物，傈麦，小米，山药，芋头，土豆， 加白菜豆角绿菜花，和苹果香蕉，这就是我全部的食谱。可喜的是原有的过敏症状渐渐消失。可是，一两周前，渐渐的有了新的皮疹和肠胃不调症状。看来我真得去查肠炎症了。 那传说中的LEAKY GUT 可能正在引起我新的过敏。真是步步惊心！希望我不必走到完全无谷物的饮食。还是从网上买了本书

Name (ñame，ronounced nyAH-may 发音是＂那美＂)is a root vegetable that sometimes is also called wild-yam. 这类＂山药＂植物是薯科的植物，所以又叫薯蓣／薯芋（yam)，因为养分储藏在块根块茎里面，英语里面叫它们tuberiferous plant （tuberous plant）块茎植物（如土豆，芋頭、蓮藕）和tuberous root（块根植物，如红薯）。
Subterranean tuber of a true yam (Dioscorea sp.), the third most important tropical root crop after cassava and sweet potatoes. The venation and shiny, heart-shaped leaves of true yams are unmistakable compared to those of sweet potatoes and other root crops.
Tropical Yams Named After Dioscorides
Although rarely seen in North America, true yams (薯蓣， Dioscorea spp., Dioscoreaceae) are the third most important tropical "root" crop after cassava (木薯类，Manihot esculenta, Euphorbiaceae) and sweet potato (红薯类，Ipomoea batatas, Convolvulaceae). This is especially true in West Africa, parts of Central America and the Caribbean, the Pacific Islands, and Southeast Asia. Other important starchy "root" crops are taro and dasheen (芋头类，Colocasia esculenta, Araceae), the source of Polynesian poi, arrowroot (竹芋，蒟蒻薯， Maranta arundinacea, Marantaceae), and achira (蕉芋，美人蕉块茎 Canna edulis, Cannaceae).
The true yam is about 20 percent starch and as a food is very similar to a potato. The generic name commemorates Dioscorides, the ancient Greek physician and naturalist (1st Century AD). Dioscorides authored the classic De Materia Medica, a five volume reference of several thousand plant drugs that was used for 15 centuries. The most commonly cultivated edible yams are D. rotundata and D. cayensis in Africa, D. alata and D. esculenta in Asia, and D. trifida in the New World, although many cultivated varieties are known. They are climbing perennial vines with shiny, heart-shaped leaves, arising from large underground stems that are technically called tubers rather than roots. Like a potato, the tubers can be propagated by planting sections containing the "eyes" or buds; however, harvesting them is a laborious task because the tubers are deeply buried. Dioscorea is a large genus with more than 600 species. An African species called elephant's foot or Hottentot's bread (D. elephantipes) produces a massive basal stem (caudex) weighing up to 700 pounds (318 kg). The above-ground part of this caudex resembles the shell of a tortoise; hence the common name of "turtleback plant." Like other caudiciform xerophytes (desert plants with enlarged basal stems), the vine relies on carbohydrates and moisture stored in its stem during extended periods of drought. During severe drought conditions the gigantic tuberous stems are eaten as famine food by Hottentots. Luckily for the Hottentots, the tuberous stems are thoroughly cooked because they contains toxic saponins that are broken down during the heating process. Although not a common vegetable, this plant would easily take the record of "World's Largest Vegetable." Another unusual African yam is the air potato (Dioscorea bulbifera). It has small or no subterranean tubers, but instead develops large, liver-shaped aerial tubers up to four pounds (2 kg) each. In New Guinea and Melanesia special ceremonial yams weighing over 120 pounds (54 kg) are grown to reflect the grower's status in the community. The yams are used for gifts and ritualized exchanges. A yam festival is held at harvesttime during which the tubers are covered by elaborate woven masks. There are reportedly yams in tropical Asia and the South Pacific that are much larger. In fact, there is one rather dubious, unconfirmed report of an enormous yam on the island of Pohnpei that was 10 feet (3 m) in length and weighed up to 1500 pounds (680 kg). Rumors have it that at least 10 people were required to carry it. REMEMBER THAT THIS RECORD IS UNSUBSTANTIATED AND MAY NOT BE TRUE.
