When you eat and your blood sugar rises, insulin is secreted into the blood.
當你吃東西導致血糖升高的時候，胰島素會被分泌到血液中。
It prompts your muscle and fat cells to let glucose in and jump starts the conversion of sugar to energy.
它促進你的肌肉和脂肪細胞吸收葡萄糖，并且快速開始從糖到能量的轉換。
The degree to which a unit of insulin lowers the blood sugar helps us understand something called insulin sensitivity.
單位量的胰島素降低血糖的程度能幫助我們理解所謂的胰島素敏感性。
The more a given unit of insulin lowers blood sugar, the more sensitive you are to insulin.
給定單位量的胰島素降低的血糖濃度越多，就說明你對胰島素越敏感。
If insulin sensitivity goes down, that's known as insulin resistance.
如果胰島素敏感度降低，就被稱為胰島素抗性。
The pancreas still sends out insulin, but cells, especially muscle cells,
胰腺仍然會釋放胰島素，但是細胞，特別是肌肉細胞，
are less and less responsive to it, so blood sugar fails to decrease, and blood insulin continues to rise.
對胰島素做出的反應越來越少，因此血糖濃度無法降低，而血液中胰島素還會持續增加。
Chronically consuming a lot of carbohydrates may lead to insulin resistance,
長期攝入大量碳水化合物可能會導致胰島素抗性，
and many scientists believe that insulin resistance leads to a serious condition called metabolic syndrome.
許多科學家們相信胰島素抗性會導致一種嚴重的病，叫做代謝綜合征。
That involves a constellation of symptoms, including high blood sugar,
代謝綜合征有許多癥狀，包括高血糖，
increased waist circumference, and high blood pressure.
變大的腰圍，和高血壓。
It increases the risk of developing conditions, like cardiovascular disease and type II diabetes.
它增加了患病的風險，比如心血管疾病和II型糖尿病。
And its prevalence is rapidly increasing all over the world.
代謝綜合征的患病率在全球范圍內增長迅速。
As much as 32% of the population in the U.S. has metabolic syndrome.
多達32%的美國人患有代謝綜合征。
So let's get back to your diet.
再回到你的日常飲食吧。
Whether your food tastes sweet or not, sugar is sugar, and too many carbs can be a problem.
不管你的食物嘗起來甜不甜，糖就是糖，攝入過多的碳水化合物會引發健康問題。
So maybe you'll want to take a pass on that pasta sushi roll pita burrito donut burger sandwich.
那么你也許不會再選擇吃意大利面，壽司，皮塔餅，墨西哥玉米卷，甜甜圈，漢堡和三明治了吧。
