Scientists have conducted tests on mice showing that fasting could have many health benefits. Fasting is eating or drinking very little or nothing for a short period of time. It is usually around 24 hours but can be for a few days. The tests were carried out by scientists at universities in the USA and Italy. They found that occasional fasting in mice could reduce the risk of diabetes, heart disease, cancer and other diseases. The scientists fed mice for four days on a low-calorie, low-protein and low-carbohydrate but high-fat diet. They then gave the mice just 10% of their normal calorie intake for three days. The scientists found this diet made the pancreas in the mice work better.

科學(xué)家對(duì)老鼠進(jìn)行了實(shí)驗(yàn)，發(fā)現(xiàn)禁食有許多健康益處。禁食是指在比較短的一段時(shí)間內(nèi)，食用或飲用很少的食物或水，甚至不吃不喝。持續(xù)的時(shí)間通常是24小時(shí)，也可以持續(xù)幾天。實(shí)驗(yàn)由美國(guó)和意大利幾所大學(xué)的科學(xué)家進(jìn)行。他們發(fā)現(xiàn)，老鼠偶爾禁食可以減少糖尿病，心臟病，癌癥和其他疾病的風(fēng)險(xiǎn)?？茖W(xué)家連續(xù)四天給老鼠喂食低卡路里，低蛋白質(zhì)和低碳水化合物，但是高脂肪的飲食。然后連續(xù)三天給他們提供的熱量只有正常情況下攝入能量的10%?？茖W(xué)家發(fā)現(xiàn)，這種飲食可以讓老鼠體內(nèi)的胰腺更好地運(yùn)作。

The pancreas is an organ in the body that uses special cells called beta cells to produce the hormone insulin. The body uses insulin to break down glucose (a kind of sugar) in the blood. People with diabetes have trouble producing enough insulin so they have health problems because there is too much sugar in their blood. This can cause death. In type 1 diabetes, the pancreas stops producing insulin. In type 2 diabetes, either not enough insulin is produced or the insulin that is produced has no effect. Scientists said the mice on the fasting diet produced increased amounts of beta cells and insulin. They said their results were very promising and that tests now need to be done on humans.

胰腺是體內(nèi)一個(gè)器官，使用一種名叫β-細(xì)胞的特殊細(xì)胞來(lái)生成胰島素。身體利用胰島素來(lái)分解血液中的葡萄糖。糖尿病人不能生成足夠的胰島素，血液中血糖過(guò)多，因此會(huì)出現(xiàn)健康問(wèn)題。糖尿病嚴(yán)重者會(huì)導(dǎo)致死亡。在1型糖尿病中，胰腺停止生成胰島素。在2型糖尿病中，胰腺不能生成足夠的胰島素，或者生成的胰島素?zé)o效。科學(xué)家表示，禁食的老鼠生成的β-細(xì)胞和胰島素?cái)?shù)量都有所增加。他們表示，他們的結(jié)果非常有價(jià)值，現(xiàn)在還需要對(duì)人進(jìn)行實(shí)驗(yàn)。
