麸质对人体的危害
Dietary fiber, including bran, is an essential component of a healthy diet. However, excessive consumption of bran or other fibrous materials can have negative effects on the human body. Here are some potential hazards associated with excessive intake of bran or fiber:
1. **Digestive Issues**: Bran is rich in insoluble fiber, which can be difficult for some people to digest. Consuming too much bran can lead to bloating, gas, and abdominal discomfort. It can also cause constipation or diarrhea in some individuals.
2. **Nutrient Absorption**: Excessive consumption of bran can interfere with the absorption of certain nutrients in the digestive tract. Bran contains phytic acid, which can bind to minerals like calcium, iron, and zinc, making them less available for absorption by the body.
3. **Gut Health**: While fiber is generally beneficial for gut health, consuming too much bran can disrupt the balance of bacteria in the gut. This imbalance can lead to digestive issues, inflammation, and other gastrointestinal problems.
4. **Dehydration**: Bran absorbs water in the digestive tract, which can lead to dehydration if not enough fluids are consumed. This can result in constipation and other complications.
5. **Weight Loss**: Some people may consume large amounts of bran in an attempt to lose weight, as it can make them feel full without adding many calories. However, excessive consumption of bran for this purpose can be harmful and may lead to nutrient deficiencies and other health issues.
In conclusion, while bran and other fibrous materials are important for a healthy diet, it is crucial to consume them in moderation. Excessive intake of bran can have negative effects on digestion, nutrient absorption, gut health, hydration, and overall well-being. It is always best to consult with a healthcare provider or nutritionist before making significant changes to your diet.
麸质对人体的危害是谁提出的
麸质对人体的危害是由多个机构和研究者提出的。以下是其中一些关键信息：
1. 醉早提出者：麸质过敏的概念醉早可以追溯到19世纪末，由英国医生Samuel Wilks在1887年首次描述。
2. 现代研究：在20世纪中后期，随着食品工业的发展和人们对食物过敏认识的提高，麸质过敏和不耐受的概念逐渐被广泛接受。1968年，英国医学杂志《柳叶刀》发表了一篇关于乳糜泻的研究，指出小麦、大麦和黑麦中的麸质可能导致麸质不耐受或过敏。
3. 具体危害：
- 乳糜泻：这是一种自身免疫性疾病，患者的免疫系统错误地攻击小肠壁，导致营养吸收不良。
- 麸质敏感性：除了乳糜泻外，还有一种称为“非乳糜泻麸质敏感性”的状况，其症状包括腹胀、腹泻、便秘、头痛、疲劳等，但不会导致免疫系统攻击身体组织。
4. 权威机构：世界卫生组织（WHO）和联合国粮食及农业组织（FAO）下属的国际食品法典委员会（Codex Alimentarius）也认可了麸质过敏和不耐受的存在，并提供了相关的指导标准。
总之，麸质对人体的危害是由多个机构和研究者在不同时间点提出的，这些研究和观点共同支持了麸质过敏和不耐受的存在及其对人类健康的潜在影响。
