中新网北京6月11日电（记者XXX报道）——针对关于膳食纤维存在的误解，近期专家进行了解释。膳食纤维虽不能被胃肠道消化吸收，也不会产生能量，但这并不意味着它没有营养。相反，膳食纤维被誉为“第七大营养素”，对人体健康具有诸多益处。
专家指出，膳食纤维能够减轻血糖波动，有助于控制糖尿病患者的病情。此外，它能够促进肠道蠕动，缓解便秘，并软化大便，从而降低痔疮风险。对于经常遭受腹泻困扰的人来说，膳食纤维还具有调节肠道功能的作用。
值得注意的是，膳食纤维还能增加食物体积，让我们在摄入较少热量的情况下就能感到“吃饱”，有助于控制体重和避免热量摄入超标。同时，它还能改善肠道菌群状态，优化人体内部环境，进而促进神经递质的合成。
综上所述，膳食纤维虽不能为人体提供能量，但它所带来的健康益处不容忽视。在日常饮食中适量摄入富含膳食纤维的食物，将有助于维护人体健康。

China News, Beijing, June 11th (reported by XXX) – Recent experts have addressed common misunderstandings about dietary fiber. Although it cannot be digested and absorbed by the gastrointestinal tract and does not produce energy, this does not mean it is devoid of nutrition. In fact, dietary fiber is known as the “7th nutrient” and has numerous benefits for human health.
Experts point out that dietary fiber can mitigate fluctuations in blood sugar, which is beneficial for controlling diabetes. Additionally, it promotes intestinal motility, relieves constipation, softens stool, and reduces the risk of痔疮 (a type of skin tag or skin lesion). For those who often suffer from diarrhea, dietary fiber also has a role in regulating intestinal function.
It is noteworthy that dietary fiber can increase food volume, allowing us to feel “full” with fewer calories, helping to control weight and avoid excessive calorie intake. At the same time, it improves the state of intestinal flora, optimizes the internal environment of the human body, and promotes the synthesis of neurotransmitters.
In summary, although dietary fiber cannot provide energy to the human body, its health benefits cannot be ignored. Consuming foods rich in dietary fiber in moderation in daily meals will help maintain human health.
