「易過食生菜」是廣東話易如反掌的意思，生菜究竟有多容易吃呢？生食熟食皆宜，生菜含水量高，纖維含量比較低，烹煮時間很短已足夠，而且易於咀嚼，的確適合大部份體質人士食用。從中醫角度來看，生菜屬性偏涼，味甘苦，有清熱生津、利尿通乳、消水腫的功效，由於苦味入心，很適合炎熱的夏天食用，因為帶苦的食物有清熱的功效。
除了常見的西生菜，其實生菜家族種類繁多，生菜是菊科萵苣屬的蔬菜，葉萵苣又分為結球、半結球和不結球形態，結球萵苣代表就是西生菜；常用來做沙律的牛油生菜和意大利生菜就是半結球萵苣；而不結球萵苣就有唐生菜及油麥菜。至於萵筍就是莖用萵苣，莖部肥大，其實也是生菜家族的成員。

生菜 — 性涼，有清熱生津、利尿通乳、消水腫的功效，適合小便不暢及水腫者食用，產後母乳不足或乳腺不通皆可適量食用。由於性涼，脾胃虛寒及尿頻者不宜多吃。

Lettuce can clear heat and reduce water retention
In Cantonese, “easier than eating lettuce” is a phrase used to describe something that can be done easily. So how easy is it to eat lettuce? Lettuce can be eaten raw or cooked, has high water content and low in fiber, does not require long hours of cooking. It is also easy to chew, making it suitable for individuals with body condition of all sorts.

From the perspective of Chinese medicine, lettuce is cool in nature, bittersweet in taste, able to clear heat, promote saliva secretion, diuresis and lactation, as well as reduce water retention. Its bitterness also makes it suitable for summer consumption, as the taste is effective in clearing body heat.

Other than the commonly known iceberg lettuce, there are many different varieties within its genus. Lettuce is from the Asteraceae family and the Lactuca genus, and the leafy lactuca (lettuce) is further divided into spherical, semi-spherical and non-spherical types. Iceberg lettuce is one of the spherical types; butter lettuce and Italian lettuce, commonly used in salad, are semi-spherical; whereas examples of non-spherical types are Chinese lettuce and Romaine lettuce. Meanwhile, the augustana variety is thick on its stem, but still belongs to the genus of lettuce.

Lettuce – cool in nature; can clear heat, promote saliva secretion, diuresis and lactation, as well as reduce water retention, suitable for individuals with urination and water retention problems. Mothers who are unable to produce sufficient breast milk after delivery should eat lettuce in an appropriate amount. Since it is cool in nature, individuals who are diuretic and experience asthenic cold in the spleen and stomach should not consume excessively.

在制定限量標準時，最重要的兩大考量就是每日容許攝取量（acceptable daily intake，簡稱ADI）以及國人飲食習慣。每日容許攝取量是指每人每天可以接受的劑量，這個數據是經過許多科學試驗後，找出身體能夠容忍的最大劑量（超過該劑量會開始對健康造成危害的劑量），之後考量到每個人不同的體質，再將這個劑量除以安全係數（通常是100），就會得到每日容許攝取量。～
