从营养学角度讲，健康不仅与营养素“吃多少”（量）有关，而且“何时吃”（时间）也有讲究。近期，日本早稻田大学尖端生命医学中心研究小组在《营养前沿》杂志发表的学术论文报告，早餐多吃蛋白质，午餐多吃纤维素，对降低血压、保持血压平稳十分有利。

From the perspective of nutrition, health is not only related to the "how much" (quantity) of nutrients, but also to "when" (time). Recently, the research team of the cutting-edge life medicine center of Waseda University in Japan reported in an academic paper published in the journal Nutrition frontier that eating more protein for breakfast and more cellulose for lunch is very beneficial to reducing blood pressure and maintaining stable blood pressure.

早吃蛋白午补纤维，控血压

Eat protein early, supplement fiber in the afternoon, and control blood pressure

研究小组利用一款与饮食和体重管理有关的应用程序，采取问卷调查方式，以2402名平均年龄45.95岁的成人（男性29.4%）为对象，根据收缩压水平将血压分为6类并进行评价（排除降压药服用者），分析研究早中晚三餐及零食的营养素摄取量与血压的关系。

Using an application related to diet and weight management, the research team took the form of questionnaire survey, and took 2402 adults with an average age of 45.95 years (male 29.4%) as the subjects. According to the systolic blood pressure level, the blood pressure was divided into 6 categories and evaluated (excluding antihypertensive drug users), and the relationship between the nutrient intake of three meals and snacks in the morning, noon and evening and blood pressure was analyzed and studied.

结果表明，早餐蛋白质和午餐纤维食物摄取量越多，血压越低。还有，午餐的钠/钾比值（钠摄取量除以可降低血压的钾摄取量）与血压有显著关联，能量和脂肪摄取仅在晚餐与血压有显著关联，零食的钠/钾比值与血压有关联，即吃午餐和零食时摄取盐分越多，血压越高；吃晚餐时，能量和脂肪摄取量越多，血压越高。研究未发现一日三餐的碳水化合物摄取量（包括零食）以及饮酒量与血压有明显关系。

The results showed that the more breakfast protein and lunch fiber food intake, the lower blood pressure. In addition, the sodium / potassium ratio of lunch (sodium intake divided by potassium intake that can reduce blood pressure) is significantly related to blood pressure, energy and fat intake is only significantly related to blood pressure at dinner, and the sodium / potassium ratio of snacks is related to blood pressure, that is, the more salt intake during lunch and snacks, the higher blood pressure; When eating dinner, the more energy and fat intake, the higher blood pressure. The study did not find a significant relationship between carbohydrate intake (including snacks) and alcohol consumption of three meals a day and blood pressure.

研究人员认为，上述研究从时间营养学的角度，阐述了营养素摄取时间对血压的影响，并为合理摄取提供了依据。通过改变钠和钾等特定营养素的摄取时间，将有助控制好高血压。

The researchers believe that the above research expounds the influence of nutrient intake time on blood pressure from the perspective of time nutrition, and provides a basis for reasonable intake. By changing the intake time of specific nutrients such as sodium and potassium, it will help to control hypertension.
