一天中,咖啡什么时候喝更健康?
每天,很多人都会习惯喝咖啡,靠它为自己提神醒脑。困了来一杯,累了来一杯,甚至一天喝好几杯都不嫌多。但你有没有想过,同样一杯咖啡,喝的时间不同,对健康的影响可能截然不同?
01
早上喝咖啡有益代谢健康
近日,发表于《英国营养学杂志》的一项研究表明,早上喝咖啡有益代谢健康。
中南大学湘雅二医院心血管团队依托美国国家健康和营养调查数据,对1.16万名参试者的相关数据展开了深入分析,比较不同喝咖啡习惯人群的健康差异。结果发现,跟不喝咖啡的人相比,早上喝咖啡的参试者代谢综合征的患病风险下降20%;而下午或晚上喝咖啡,则无明显保护效果。
代谢综合征听起来陌生,却离我们很近。它不是单独的一种疾病,而是包括肥胖、高血脂、高血压、高血糖、高尿酸、脂肪肝等。
还有研究发现,与不喝咖啡的人相比,早上喝咖啡的人心血管病死亡风险降低31%、全因死亡风险降低16%,但其他时间喝咖啡的人相关风险并没有降低。
02
为何早上喝咖啡有益代谢?
为什么同样是喝咖啡,时间不同,效果差异这么大?研究人员分析——
·抗氧化物质起作用
咖啡富含绿原酸、多酚等抗氧化物质,早上进食后饮用,能延缓主食中碳水化合物的吸收利用,减少肝脏合成甘油三酯,改善胰岛素抵抗,降低炎症指标,而且不会影响夜间睡眠。
·不打乱昼夜节律
如果下午、晚上喝咖啡,其中的咖啡因会抑制褪黑素分泌,导致睡眠变差,进而加剧代谢紊乱。
·配套健康作息习惯
习惯早上喝咖啡的人群,大多规律吃早餐、作息稳定,三餐规律本身就能减少代谢异常叠加风险。
03
健康喝咖啡有4个要点
研究人员提醒,把咖啡“喝对时间”之前,先要“喝对方式”。
·不要空腹喝
咖啡因会刺激胃酸分泌,增加胃酸浓度,因此不建议空腹喝咖啡,最好吃完早饭后再喝。
·合理搭配更健康
搭配杂粮、蔬菜等天然食材,能进一步改善代谢。若时间紧张,喝咖啡前最好吃些富含碳水化合物的食物,如面包、包子及各种饼类等。
·记住一个推荐量
一般建议,健康人群每天摄入的咖啡因量最好控制在210毫克左右。如果按每杯150毫升咖啡含75毫克咖啡因计算,每天可以喝2~3杯。
·特殊人群少喝或不喝
儿童青少年、孕妇和哺乳期女性、骨质疏松症或消化道疾病患者、对咖啡因敏感者、失眠者,尽量不喝或少喝咖啡。

When is it healthier to drink coffee in a day?

Every day, many people get used to drinking coffee to refresh themselves and their minds. Drink a cup when you're tired, or even several cups a day. But have you ever thought that the same cup of coffee, consumed at different times, may have vastly different effects on health?

01

Drinking coffee in the morning is beneficial for metabolic health

Recently, a study published in the British Journal of Nutrition showed that drinking coffee in the morning is beneficial for metabolic health.

The cardiovascular team of Xiangya Second Hospital of Central South University conducted an in-depth analysis of relevant data from 11600 participants based on the National Health and Nutrition Examination Survey data in the United States, comparing the health differences among people with different coffee drinking habits. It was found that participants who drank coffee in the morning had a 20% lower risk of developing metabolic syndrome compared to those who did not drink coffee; Drinking coffee in the afternoon or evening has no significant protective effect.

Metabolic syndrome may sound unfamiliar, but it is very close to us. It is not a standalone disease, but includes obesity, hyperlipidemia, hypertension, hyperglycemia, hyperuricemia, fatty liver, etc.

Another study found that compared to those who do not drink coffee, those who drink coffee in the morning have a 31% lower risk of cardiovascular disease death and a 16% lower risk of all-cause death, but those who drink coffee at other times do not have a reduced risk.

02

Why is drinking coffee beneficial for metabolism in the morning?

Why is there such a big difference in the effect of drinking coffee at different times? Researchers analyze——

·Antioxidants work

Coffee is rich in antioxidants such as chlorogenic acid and polyphenols. Drinking it in the morning can delay the absorption and utilization of carbohydrates in staple foods, reduce the synthesis of triglycerides in the liver, improve insulin resistance, lower inflammation indicators, and will not affect nighttime sleep.

·Do not disrupt the circadian rhythm

If you drink coffee in the afternoon or evening, the caffeine in it will inhibit the secretion of melatonin, leading to poor sleep and exacerbating metabolic disorders.

·Supporting healthy sleep habits

People who are accustomed to drinking coffee in the morning mostly have a regular breakfast and a stable schedule. Regular meals can reduce the risk of metabolic abnormalities.

03

There are 4 key points to drinking coffee healthily

Researchers remind that before drinking coffee at the right time, it is important to drink it in the right way.

·Do not drink on an empty stomach

Caffeine can stimulate the secretion of stomach acid and increase its concentration, so it is not recommended to drink coffee on an empty stomach. It is best to drink it after breakfast.

·Reasonable combination is healthier

Pairing with natural ingredients such as grains and vegetables can further improve metabolism. If time is tight, it is best to eat carbohydrate rich foods such as bread, buns, and various types of cakes before drinking coffee.

·Remember a recommendation quantity

It is generally recommended that healthy individuals limit their daily intake of caffeine to around 210 milligrams. If calculated based on 75 milligrams of caffeine per 150 milliliters of coffee, one can drink 2-3 cups per day.

·Special groups drink less or not at all

Children and adolescents, pregnant and lactating women, patients with osteoporosis or gastrointestinal diseases, those sensitive to caffeine, and those with insomnia should try to avoid or reduce their consumption of coffee.
