燕窝是金丝燕吐的丝状物，为哺育新一代所筑造的窝，而银耳是一种食用菌。燕窝含有大量的唾液酸。为水溶性蛋白质，含有十八种氨基酸。燕窝的主要功效是：增强免疫力，让细菌不易附着在呼吸系统粘膜上，愈合、修复受损细胞。燕窝中含有三种不同的营养物质，为特别：唾液酸Sialic acid (N-acetylneuramic acid)，表皮生长因子(EGF)和集落刺激因子(CSF)。燕窝是纯天然的滋养保健食品，它的主要作用是：燕窝中含有的唾液酸也称为燕窝酸能增强免疫力，让细菌不易附着在呼吸系统粘膜上，愈合、修复受损细胞。 银耳为门担子菌门真菌银耳的子实体，生于阔叶树腐木上。古今史著和历代医学家通过临床验证，银耳有强精补肾，滋阴润肺，生津目咳，清润益胃，补气和血，强心壮身，补脑提神，嫩肤美容，延年益寿，抗癌之功效。
此汤具有养血安胎的作用。孕妇若有习惯性流产，怀孕后食欲不振、腰痛或下腹坠胀等现象，可吃此汤养血安胎。选用的巢工厂燕网是燕窝中间“安燕”部份，是支撑蛋只及小燕的纤细网状物，口感细腻润滑，容易消化吸收。
燕窝的需求因此持续攀升也有人认为，中国人食用燕窝已有五百年多年的历史，而明代郑和是中国食用燕窝的人。据史书记载，早在郑和下西洋时，远洋船队在海上遇到了大风暴，停泊在马来群岛的一个荒岛处，食物紧缺。他们无意中发现了藏在悬崖峭壁上的燕窝。
想补胶原，不能靠燕窝关于猪皮猪蹄。在我们的日常饮食中，蹄筋和肉皮等富含胶原蛋白，但是这种大分子的蛋白人体不能直接吸收，由于胶原蛋白的三维螺旋结构决定了其具有很强大的稳定性，在人体的消化系统(胃和小肠)内转化率很低，而且脂肪含量较高，容易导致肥胖和高血脂，此外，猪蹄里所含胶原的含量与高提纯的胶原蛋白粉不可相提并论。有一种说法：吃一克小分子胶原蛋白，相当于吃一斤猪蹄。
而且不同等级品种的燕窝口感也不盡相同。现有许多燕窝商家利用水份来谋利润。同时燕窝的干度也不会达到100%，因为运输过程中太干会碎掉，特别是盏燕窝人工挑毛是会用水冲洗，软化后挑毛，然后阴干放在冰箱或有一定湿度的房间存放，印尼燕屋出来的燕窝含水量在85%左右，然后运输过程中有会慢慢损耗水份，也能保持燕窝不碎燕窝宜密封放冰箱里存放，香港买的燕窝上面会写上“储存于雪柜”我之前主要是自己吃，没有放在冰箱里，就放在类似乐扣的盒子里我出售的燕窝干度90%~95%，燕窝不能在太阳下晒及用热风吹，如果放冰箱没有密封好，太湿了，可以拿出来在空调房自然吹干，切不可在太阳下晒及用热风吹，营养会大打折扣2、颜色：天然燕窝的颜色呈白色，带点黄，绝对不能是像白纸一样的白。
As a collector and type of antiquary not disdaining a good bargain, and perhaps influenced by the lineage of shrewd bankers, from which he sprang, Lorenzo made more than one good stroke of business. From Pope Sixtus IV he managed to buy the artistic treasure of the Holy See at such a ridiculous price as to arouse protests from the Pontifical accountants. The deal, which was carried through by Lorenzo’s uncle, Giovanni Tornabuoni, caused a scandal that only the Pope’s authority managed to silence, and the Medici collection became enriched by many fine pieces. Among them, the so-called “Tazza Farnese,” now one of the finest pieces of the Naples Museum, to which the inventory of the collection gives a value of 10,000 ducats, and the rare Greek work known as the “Rape of the Palladium,” rated by the same inventory at the sum of 1500 ducats. This celebrated cameo had formerly belonged to Niccoli. Donatello copied it for one of his medallions of the Medici palace. There were other dealings between the Medici and the Holy See, but we fail to know how advantageous they may have been for either side. In the year 1460 the Medici sold a piece of tapestry to Pope Pius II for the not inconsiderable sum of 1200 golden ducats, and later on, through the above-quoted agent, Giovanni Tornabuoni, in the year 1484 several yards of common tapestry were sold to the Pope by the Medicis.
