牛奶真的能減壓?
A protein found in milk is the latest treatment for stress. The protein, lactium, appears to have a calming effect on the body by lowering blood pressure and reducing levels of cortisol, a hormone released when the body is stressed.
最近，科學家在牛奶中發現了一種新的可以減緩壓力的蛋白質，這種名爲酪蛋白水解物的蛋白質具有鎮靜作用，當人體處於壓力狀態下時，這種蛋白質可通過降低血壓、降低皮質醇（一種人處於壓力下腎上腺分泌出的壓力荷爾蒙）來有效緩解壓力。
Chronic stress is linked to a range of conditions, including depression and heart disease. Scientists first began studying the stress-busting qualities of milk over 20 years ago, spurred on by the observation that babies become calm and settled after feeding on milk.
慢性壓力和一定的健康狀況有關，如沮喪、心臟病。科學家們從20多年前就開始研究牛奶的這種減壓特質，激勵科學家們這樣做的原因是嬰兒們喝完牛奶後就會變得平靜。
Tests suggested that a protein - casein - played a key role.
試驗結果顯示，這種名爲酪蛋白的蛋白質起了關鍵作用。
But adults, with their more mature digestive system, would need to drink impossibly large quantities of milk for the same benefit. Now a French company, Ingredia Nutritional, has developed the protein into lactium, a highly concentrated form.
但是對於成年人來說，由於消化系統已經成熟，要喝大量的牛奶纔可能達到這種效果。日前，一家名爲Ingredia Nutritional的法國公司，將這種蛋白質進行了高度濃縮，製成了酪蛋白水解物。
