【脂肪都有分顏色？】- 營養生Negimen

【脂肪都有分顏色？】不少人對「脂肪」十分害怕，無論是食物中的脂肪和身體內的脂肪都希望愈少愈好。但您知道原來不同顏色的脂肪於我們體內都有不同功用的嗎？

我們常常希望減掉的是白色脂肪，一般儲存於我們的皮下和內臟附近，負責把消化後多餘的能量儲存起來，留待有需要時使用，亦為我們的內臟提供保護作用。白色脂肪亦同時是不少荷爾蒙的主要分泌合成來源，當體內的白色脂肪太少時，不少生理功能會因而受影響。

啡色脂肪則存在於鎖骨、頸部以及脊柱上，佔成人身體不到5%，能快速燃燒脂肪產生熱能。一般在新生嬰兒身上含量較多，以維持嬰兒體溫正常。普遍被認為能夠消耗白色脂肪，為體重控制的重要組織。

米色脂肪由白色脂肪於寒冷刺激下或運動後褐化產生，所以普遍混在白色脂肪之中。跟啡色脂肪一樣，可以快速燃燒脂肪並防止肥胖。

【Fats in different colors?】Many people are afraid of "fat" and wish to limit the amount of fat content no matter in food or in their own body. But did you know that fats of different colors have different functions in our bodies?

What we often want to lose is white fat, which is generally stored under our skin(subcutaneous) and near our internal organs(visceral). It is responsible for storing the excess energy after digestion and saving it for use when needed. It also provides protection for our internal organs. White fat is also the main source of secretion and synthesis of many hormones. When there is insufficient white fat in the body, many physiological functions will be affected.

Brown fat is present on the upper back, clavicles and vertebrate, which accounts for less than 5% of the adult body. It can burn fat to produce heat. Generally, it is contained in newborn babies to maintain a normal body temperature. It is generally considered to be able to consume white fat and is an important tissue for weight control.

Beige fat is produced by browning of white fat under cold stimulation or after exercise, so it is generally mixed with white fat. Like brown fat, it can burn fat quickly and prevent obesity.
