最新研究称高果糖间接“喂养”癌细胞、成肿瘤“加速器” ！那水果还能放心吃吗

Core Viewpoint - A recent study from Columbia University indicates that fructose may indirectly promote tumor growth through liver metabolism, sparking discussions about the health implications of fruit consumption [1] Group 1: Research Findings - The study found that fructose metabolism in the liver generates lysophosphatidylcholine (LPC) and other nutrients that support tumor growth, rather than serving as a direct energy source for tumor cells [3] - Compared to glucose, fructose has a significantly lower metabolic efficiency, with tumor cells showing limited ability to directly metabolize fructose [3][4] - An experiment demonstrated that cervical cancer cells (CaSki) proliferated faster when co-cultured with liver cells in the presence of fructose, indicating that fructose's effect on tumor growth is mediated through liver metabolism [4] Group 2: Health Implications - The study raises concerns about the health risks associated with high fructose intake, particularly from processed foods containing high-fructose corn syrup, which is commonly used in beverages and snacks [4][5] - While fruits contain fructose, they also include dietary fiber and vitamins that mitigate the rapid absorption of sugar, contrasting with the quick absorption of free fructose from processed foods [6] - Experts recommend limiting added sugars, including fructose, for both cancer patients and the general public, emphasizing the importance of reading food labels to avoid high-fructose ingredients [6][7]
