虾青素的食物来源
虾青素,又称虾红素,是一种天然抗氧化剂, 是类胡萝蔔素的一种。与其他类胡萝蔔素一样,虾青素属于一种脂溶性及水溶性的色素,在虾、蟹、鲑鱼、藻类等海洋生物均可找到。虾青素的主要食物来源有:
藻类
藻类含虾青素的食物有, 海产藻类如礁膜、石莼、海带、裙带菜、紫菜、石花菜等。食用淡水藻类如雨生红球藻、地木耳、发菜等。含虾青素的食物的仅是少数几种藻类和浮游生物产生的,多数只含有虾青素的中间体β-胡萝卜素、维生素E等。其中雨生红球藻是自然界中含虾青素的食物最丰富的生物,其虾青素含量可达干重的3. 0% ,甚至更高,被誉为天然虾青素的“浓缩品”。
虾类
含虾青素的食物有,淡水虾类如克氏鳌虾(小龙虾)、青虾、河虾、草虾、基围虾等淡水虾。海水虾类:有龙虾(中国龙虾)、海虾(红虾、大红虾)、对虾(明虾)、基围虾、琵琶虾等海水虾。半咸水虾如白虾等. 不管何种虾,除含核心价值是含虾青素的食物以外,根据科学的分析,虾可食部分蛋白质占16~20%左右,营养价值很高,其肉质和鱼一样松软,易消化,但又无腥味和骨刺,同时含有丰富的矿物质(如钙、磷、铁等),海水虾类还富含碘质,对人类的健康极有裨益。
蟹类
蟹类含虾青素的食物中90%为海产,可食用的有三疣梭子蟹(海蟹)、远海梭子蟹、青蟹(又称黄甲蟹、蝤蛑)等。蟹类含虾青素的食物10%为淡水产,可食用蟹类含虾青素的食物有中华绒螯蟹也称毛蟹、螃蟹、河蟹、清水大闸蟹(如梁子湖、阳澄湖大闸蟹等举世闻名)等。一般虾、蟹类含虾青素的食物1000克的虾壳中含80-100毫克虾青素,鳌虾类含虾青素的食物是所有虾、蟹类虾青素含量最高的,鳌虾类含虾青素的食物1000克的虾壳中约含800-1000毫克虾青素。不过除了油闷大虾等少数烹饪方法能把虾青素从虾、蟹壳中滤出一部分,其大多数虾青素随虾壳、蟹壳被丢弃了。食用软壳蟹或虾皮可以摄取到虾青素。
贝类
大部分贝类是海产,少数在淡水,含虾青素的食物有:淡菜、蚶、海蚌、田螺、鲍鱼、牡蛎、环文蛤(青蛤)、河蚬、蛤仔、扇贝、青口等;贝类含虾青素的食物1000克中含虾青素在10毫克以下。但对如糖尿病、痛风、自身免疫性疾病等部分病人来说,通过食用虾、蟹、贝类等含虾青素的食物摄取虾青素是不可取的,因为虾、蟹、贝类等含虾青素的食物中同时也含糖尿病忌的多糖、痛风病人忌的高蛋白质等,虾头含有毒物质砷等,对免疫性疾病的病人来说,虾、蟹、贝类等中的部分多糖和蛋白酶是引起过敏的过敏原。这类人群最好是食用雨生红球藻提纯的虾青素。
虾、蟹类、贝类等也不能和富含维生素C的水果等同食,VC等与虾、蟹类、贝类类的矿物质发生复杂的变化,不但不利于营养的吸收,还有可能造成中毒(如虾的砷中毒)。避免的办法是VC类食物与虾、蟹类、贝类等含虾青素的食物隔餐交叉进补。
鱼类
三文鱼、鲑鱼、鳟鱼、鱼籽、大马哈鱼、金枪鱼、鲤鱼、梭鱼、鳕鱼、沙丁鱼等。鱼类含虾青素的食物:1000克中含虾青素约10-40毫克。
其他
野生禽类蛋黄(禽类摄入了藻类和菌类等含虾青素的食物)、乌龟(中华草龟)、鳖(王八)、海胆、海星、海参等。其他类含虾青素的食物:1000克中含虾青素均在10毫克以下。虾、蟹等甲壳类,扇贝、青口等贝壳类,这些动物都食用含虾青素的食物的藻类和浮游生物,甲壳类和贝壳类等含虾青素食物的动物又被鱼(三文鱼,鳟鱼)和鸟(火烈鸟,朱鹭)捕食,通过食物链传递虾青素成为人类含虾青素的食物。
从饮食健康角度来说,食物链离人类越近,含虾青素的食物生物的虾青素含量就越低,其食物来源复杂,所带给危害人类健康的副产品越多(如肺吸虫病、禽流感等);食物链离人类越远,含虾青素的食物生物的虾青素含量就越高越安全。所以从藻类提取纯虾青素是含量最高最安全的含虾青素的食物。(本文整理来源于网络)

I've seen a lot of reviews on these shoes, and a lot of complaints about the squeakiness of them, but they have yet to start squeaking on me after a week or so of wearing them. They fit, feel and look great, I would buy them again.

The sound quality is clear and hierarchical, whether it is listening to songs, calling or watching videos, it is the best choice, and I would like to recommend this headset to you

2024-01-12 08:50:33--
The scales on the shoes are the WRONG color. They are supposed to be neon green but mine came with brown scales. Do not buy from this seller.
2024-01-12 08:50:32--
1ST THIS SELLER WAS A GREAT IN REPLYING TO ALL MSGS BUT THE SHOES ARE TRASH I ORDERED THE PROM NIGHTS AND QUALITY WAS VERY VERY LOW QUALITY SELLER OFFER ME A REPLACEMENT PAIR AFTER I SUGGESTED IT AND I ASKED FOR SPACE JAMS AND AFTER WAITING 3 MORE WEEKS I RECEIVED MY REPLACEMENT PAIR WITH NO BOX.THESE SHOES WAS SO FAR OFF FROM GOOD QUALITY PICS WILL PROVE BELOW THESE SHOES LOOK LIKE THEY FELL FROM SPACE AND HIT EVERY PLANE ON THE WAY DOWN NEVER ORDER FROM THIS SELLER AGAIN
2024-01-12 08:49:14--
Okay. Quality isn’t the best. Fairly obvious not genuine, but fine for the price.
2024-01-12 08:48:51--
look more expensive than they are, but they are unlikely to last long, because inexpensive materials and a soft heel will not give them a chance to stay whole for a fairly long period, especially with an active lifestyle.
size take your usual p is not small.
2024-01-12 08:48:11--
It's a good item
2024-01-12 08:48:04--

These are really good reps, one small flaw is the “BOOST” text on the bottom of the shoe looks like a thinner font than authentic. Super comfortable and really good reps.
2024-01-04 19:01:05--
Size perfectly well, excellent delivery time The quality/price ratio is good We could hope for better quality laces.

Beyond expectations!! The seller was easy to contact and the quality is great! I’m in Chicago the product arrived in approximately 25 days.
2024-01-03 23:51:23--
It’s exactly like the picture! I have a real gucci Ophelia bag as well and it’s a strong match! The only small difference between the real and this is the gold hardware is a little more of a yellow gold, it’s such a slight difference no one else will notice unless you are holding this bag against a real one side by side looking for differences.
2024-01-03 23:48:27--
DO NOT BUY FROM THIS SELLER. they sent me fake photos and the bags tag was incorrect which is a dead give away. Refused to refund me. Don’t bother with this seller, no attempt to rectify the situation
2024-01-03 23:29:09--
It’s pretty well done for the most part. One of the stones fell out though after a few wears
2024-01-03 23:28:43--
Not my fav ring but definitely it’s what you order. Never turned green I wet my hands a lot. It arrived super fast looks alright
2024-01-03 20:13:23--
