什么食物可以让我们更凉爽

Our body temperature can be influenced by far more things beyond just physical activity or the weather. Food, for example, can cause our body temperature to both rise and fall, depending on what we eat.

除了体力活动或天气之外，我们的体温还会受到更多因素的影响。例如，食物会导致我们的体温上升和下降，这取决于我们吃什么。

According to Flo Health, whole grains such as rice make the body warmer due to the fact that they are more challenging to digest. Professor and food scientist at Washington State University Barry Swanson tells TIME, "Anything with a lot of complex carbohydrates and processed foods like rice and cereal products can be more warming than cooling." The same is true even for colder food items such as ice cream. Swanson explains saying, "The sheer temperature difference gives a cooling sensation, but when your body starts to digest, you feel warm because your body has to provide energy to digest that food product. Fat is notorious for moving slowly through the digestive system so it takes more energy to digest that fat."

根据Flo Health的说法，全谷类食物如大米会使身体更暖和，因为它们更难消化。华盛顿州立大学教授兼食品科学家巴里·斯旺森告诉《时代周刊》：“任何含有大量复杂碳水化合物和加工食品(如大米和谷类产品)的东西都可能让身体变热。”即使是冰激凌等较冷的食物也是如此。斯旺森解释说：“绝对的温差会给人一种降温的感觉，但当你的身体开始消化时，你会感到温暖，因为你的身体必须提供能量来消化食物。脂肪在消化系统中移动缓慢，因此消化脂肪需要更多的能量。”

So what's going on in our digestive tract that causes our body temperature to drop and what kinds of foods can give us a chill?

那么，我们的消化道发生了什么导致我们的体温下降，什么样的食物会让我们发冷呢?

Foods with high water content can make us cooler

含水量高的食物可以让我们更凉爽

The answer as to why you're feeling cold after a meal may be due to blood flow. Experts at Healthy Women explain that blood is routed towards the digestive tract and away from the muscles and tissue after we eat, which results in a loss of heat. Those who exercise prior to a meal may feel particularly cold after eating, as they are undergoing a simultaneous loss of heat from both digestion and the decrease in physical activity.

餐后感到冷的原因可能与血液流动有关。《健康女性》杂志的专家解释说，我们吃完东西后，血液会流向消化道，离开肌肉和组织，从而导致热量流失。饭前锻炼的人可能会在饭后感到特别冷，因为他们正在经历消化热量的流失和体育活动的减少。

Alternatively, the foods themselves may be what's causing you to reach for a blanket. Foods such as hot peppers, watermelon, and leafy greens cool the body down. Food scientist Barry Swanson explains to TIME, saying, "Most raw fruits and vegetables are 80-95% water, and anything that contains a lot of water is very easy to digest and goes through the digestive system very quickly, giving you a cooling sensation."

或者，食物本身可能是导致你伸手去拿毯子的原因。辣椒、西瓜和绿叶蔬菜等食物能使身体降温。食品科学家巴里·斯旺森(Barry Swanson)向《时代》杂志解释说：“大多数生水果和蔬菜中80-95%是水，任何含有大量水的东西都很容易消化，很快通过消化系统，给人一种凉爽的感觉。”

However, the degree to which food can decrease body temperature is quite minimal, cautions Flo Health. Therefore, major temperature shifts experienced after eating could indicate a possible health condition such as hypothyroidism, anemia, or diabetes. If you find that you're consistently feeling very cold after eating, be sure to visit with your doctor to assess for any possible underlying medical conditions.

然而，Flo Health警告说，食物降低体温的程度非常小。因此，进食后出现的主要温度变化可能表明可能存在甲状腺功能减退、贫血或糖尿病等健康状况。如果你发现饭后一直感觉很冷，一定要去看医生，以评估任何可能的潜在疾病。
