Gastrointestinal System (老化始于肠道)
Discover the essential functions and organs of the gastrointestinal system, from digestion to nutrient absorption. Learn how to maintain digestive health with this comprehensive guide.
The gastrointestinal system is essential for digestion, nutrient absorption, and waste elimination. It consists of organs that work together to break down food and convert it into nutrients for energy and growth. Digestion starts in the mouth, where chewing and saliva enzymes begin breaking down food. It then passes through the esophagus to the stomach, where acids and enzymes further digest it into chyme.
In the small intestine, most nutrients are absorbed. Tiny projections called villi transfer these nutrients into the bloodstream. The liver and pancreas aid this process by releasing bile and digestive enzymes. Finally, the large intestine absorbs water, compacts waste, and eliminates it through the rectum.
Maintaining the healthy of gastrointestinal system
Maintaining a healthy gastrointestinal system is crucial for overall health. Poor digestion can lead to problems like acid reflux, IBS, ulcers, and IBD. Key factors for digestive health include a fiber-rich diet, hydration, regular exercise, and stress management. Probiotic foods like yogurt and fermented vegetables also help support gut health, which plays a vital role in digestion and immunity.

坏菌增多
肠道是人体最大的免疫器官,消化道更是身体吸收营养及排除毒素的重要器官,当肠道坏菌增多,菌丛失衡,缺乏蠕动能力的肠道就容易“未老先衰”。
肠道老化
坏菌过多,肠道开始老化,人体吸收营养和排除毒素的效率大幅降低,导致发育成长受阻,毒素滞留体内,同时免疫力降低。
身体老化+ 肠道疾病
肠道坏菌会将食物的残渣转变成有害物质或毒素,引起腹泻,便秘,严重者更大幅度增加罹患大肠癌的机率。若毒素持续累积,随着人体血液循环更会增加肝、肾负担,引致身体器官老化和一箩筐疾病。
