90年代的黄河路

科技日报讯 (记者刘霞)美国科学家开展的小鼠实验显示,生酮饮食会导致受损细胞在小鼠心脏、肾脏、肺部和大脑内积聚,加速器官衰老,增加其罹患心脏病、癌症等疾病的风险。相关论文发表于17日出版的《科学进展》杂志。

生酮饮食是一种高脂肪、低碳水化合物的饮食模式,近年来在减肥和某些疾病的治疗中受到关注。然而,这项新的研究揭示了生酮饮食可能带来的负面健康效应。研究人员发现,与正常饮食的小鼠相比,接受生酮饮食的小鼠其器官中积累了更多的受损细胞。这些细胞无法正常发挥功能,可能成为疾病发展的温床。

实验结果表明,生酮饮食对心脏的影响最为显著,小鼠心脏的受损细胞数量显著增加,这可能导致心脏功能下降,增加心脏病风险。此外,生酮饮食还可能促进肾脏、肺部和大脑中细胞的老化,增加罹患癌症等疾病的风险。

科学家们警告,这些发现并不意味着生酮饮食对所有人都是有害的,但可能对那些已经患有心脏病或癌症风险较高的人群构成额外风险。他们建议,在采取任何极端饮食模式之前,应咨询医生或营养专家,并根据个人健康状况做出明智的决定。

Title: Ketogenic Diet May Accelerate Organ Aging, Study Suggests

A study conducted by American scientists has shown that a ketogenic diet can lead to the accumulation of damaged cells in the hearts, kidneys, lungs, and brains of mice, accelerating organ aging and increasing the risk of diseases such as heart disease and cancer. The related paper was published in the journal “Science Advances” on the 17th.

The ketogenic diet is a high-fat, low-carbohydrate eating pattern that has gained attention in recent years for weight loss and the treatment of certain diseases. However, this new study reveals the potential negative health effects of the ketogenic diet. Researchers found that mice fed a ketogenic diet accumulated more damaged cells in their organs compared to those on a normal diet. These cells are unable to function properly and may serve as breeding grounds for disease development.

The results of the experiment showed that the ketogenic diet had the most significant impact on the heart, with a substantial increase in the number of damaged cells in the heart, which could lead to a decline in heart function and an increased risk of heart disease. Additionally, the diet may also promote the aging of cells in the kidneys, lungs, and brain, increasing the risk of diseases such as cancer.

Scientists warn that these findings do not necessarily mean that the ketogenic diet is harmful to everyone, but it may pose additional risks for individuals who already have heart disease or a higher risk of cancer. They suggest that before adopting any extreme eating pattern, one should consult a doctor or a nutrition expert and make a wise decision based on one’s personal health condition.
