奶酪或有助於控制血糖
Mmmm, cheese - a food as nutritious as it is delicious. Or is it?
嗯，奶酪是一種既美味又營養的食物，對嗎？On the one hand, cheese is an excellent source of minerals like calcium and magnesium, vitamins A, B2 and B12, not to mention being a complete protein.
一方面，奶酪是鈣、鎂、維生素A、維生素B2和維生素B12等礦物質的良好來源，更別提它還是一種完全蛋白質。On the other hand, cheese is also a significant source of saturated fat and sodium in our diets. To lower saturated fat intake, consuming reduced-fat cheese is sometimes recommended to lower cardiovascular disease risk.
另一方面，奶酪也是飽和脂肪和鈉的重要來源。爲降低飽和脂肪的攝入量，有時也建議食用減脂奶酪以降低心血管疾病的風險。
Paradoxically, however, there is now a growing body of evidence that people who eat lots of cheese do not have a higher risk of cardiovascular diseases, including Type 2 diabetes.
但矛盾的是，越來越多的證據表明：對於食用大量奶酪的人羣而言，他們患心血管疾病的風險（包括2型糖尿病）並沒有更高。
Our research team at the University of Alberta examined the impact of both reduced- and regular-fat cheese on insulin resistance in the bodies of pre-diabetic rats. We found that both types of cheese reduced insulin resistance, which is important to maintain normal blood sugars.
我們在阿爾伯塔大學的研究小組調查了減脂奶酪和常規奶酪對糖尿病前期大鼠體內胰島素抵抗的影響。我們發現：這兩種奶酪都會降低胰島素抵抗，這對於維持正常的血糖濃度非常重要。Cheese and insulin resistance
奶酪和胰島素抵抗Insulin resistance is a condition that commonly develops with ageing and obesity, leading to high blood glucose, and risk factor of CVD and Type 2 diabetes.
胰島素抵抗通常伴隨着衰老和肥胖發生，導致高血糖，也是心血管疾病和2型糖尿病的風險因素。Our objective was to compare how consuming reduced- versus regular-fat cheese affected insulin resistance, and to explore biochemical mechanisms that might explain any observed effects.
我們的目的是對比減脂奶酪和常規奶酪對胰島素抵抗的影響，並探究能解釋已觀察影響的生化機制。We used a rat model of insulin resistance that shares many characteristics with humans. We created the model by feeding the rats high amounts of lard. After four weeks, the rats were divided into three groups: 1) lard diet, 2) lard diet and reduced-fat cheddar cheese, 3) lard diet and regular fat cheddar cheese.
我們建立了胰島素抵抗大鼠模型，該模型與人類存在很多共同特徵。通過給大鼠投喂大量豬油，我們建立了該模型。四周後，大鼠被分成三組：1）豬油飲食，2）豬油飲食和減脂切達奶酪，3）豬油飲食和常規切達奶酪。All the diets had the same total amount of fat, only the source of it varied (lard versus cheese). The rats ate these diets for eight more weeks.
所有飲食的脂肪量相同，但來源不同（豬油vs.奶酪）。接下來的八週內，研究員對大鼠投喂這些食物。The most interesting finding in our research was that both reduced- and regular-fat cheddar cheese reduced insulin resistance in the rats. This suggests that the beneficial effects of cheese might not be related to the amount of fat but to some other component, such as the protein or the calcium.
最有意思的是，減脂切達奶酪和常規切達奶酪都降低了大鼠的胰島素抵抗。這表明：奶酪的益處可能與脂肪含量無關，但與蛋白質或鈣等其它成分相關。
