Introduction
Polysaccharides generally raise blood glucose levels. In healthy individuals, although blood glucose increases after consuming polysaccharides, it does not suddenly rise beyond the normal range, primarily because the body can appropriately secrete insulin to keep the elevated blood glucose within normal limits. However, in diabetic patients who consume excessive polysaccharides, impaired pancreatic beta-cell function may lead to insufficient insulin secretion, resulting in abnormally high blood glucose levels.
Polysaccharides generally raise blood glucose levels.
Polysaccharides are typically formed by the condensation and dehydration of multiple monosaccharide molecules, and they commonly constitute a high proportion of carbohydrates. Under normal circumstances, after healthy individuals consume polysaccharides, although their blood glucose levels may rise, the increase usually stays within the normal range. This is primarily because the body can appropriately secrete insulin to keep elevated blood glucose under control. However, in diabetic patients, consuming excessive amounts of polysaccharides may lead to abnormally high blood glucose levels due to impaired pancreatic cell function—resulting in reduced insulin secretion—or insulin resistance, whereby the body's tissues respond poorly to insulin, preventing effective utilization of glucose in the bloodstream.
It is recommended to maintain a balanced, nutritious, and reasonable diet in daily life, avoiding excessive intake of foods high in sugar, fat, and calories. Combining this with appropriate physical exercise can help reduce excess body energy and may contribute to the prevention of diabetes.
