普遍认为每天至少吃3餐,但现代生活方式正逐渐打破既往进食习惯。已发现每日进食频率可能影响多种心血管代谢风险因素,但尚未深入研究其临床价值。研究显示,与进食次数较少者相比,进食次数较多者通常血脂状况更好,胰岛素抵抗及代谢综合征发病风险更低。进食频率增加使空腹时间减少,平均血糖浓度及胰岛素分泌量降低。胰岛素浓度降低使羟甲基戊二酸单酰辅酶A还原酶活性降低,从而减少肝脏胆固醇合成。由于已证实以上代谢产物与动脉硬化、脉
It is generally believed that eating at least 3 meals a day, but the modern way of life is gradually breaking the past eating habits. It has been found that the frequency of daily feeding may affect a number of cardiovascular risk factors, but its clinical value has not yet been thoroughly investigated. Studies have shown that people who eat more often have better blood lipids than those who eat less, and have a lower risk of developing insulin resistance and metabolic syndrome. Increase in eating frequency to reduce fasting time, the average blood glucose and insulin secretion decreased. Reducing insulin concentration decreases hydroxymethylglutaryl coenzyme A reductase activity, thereby reducing hepatic cholesterol synthesis. Since it has been confirmed that the above metabolites and atherosclerosis, pulse
