What you don’t know! Vitamin B2 can not casually fill vitamin B2 deficiency disease is a very common disease. Vitamin B2, also known as riboflavin, is involved in the metabolism of sugar, protein and fat; maintains animal growth, normal vision and health of the skin and mucous membranes. Vitamin B2 deficiency (vitamin B2deficiency), also known as riboflavin deficiency disease (ARIBOFLAVINOSIS) also known as Yan thrush or tone sores, is due to vitamin B2 deficiency or insufficiency caused by body syndrome with scrotal inflammation, cheilitis, glossitis and stomatitis as the main manifestation. However, if you worry about vitamin B2 deficiency and abuse of vitamin B2, harmful to human health. Normally, the intake of vitamin B2 from food meets the needs of human beings. Vitamin B2 is widely found in foods such as milk, eggs, meat, animal offal, Cereals, vegetables and fruits (the content of animal food is higher than that of vegetable food). But the content of vitamin B2 in food is not too high, and there are many factors can cause its destruction, loss and utilization, so vitamin B2 is a kind of vitamin that people often lack. Vitamin B2 is a water-soluble vitamin, although excessive intake will be excreted from urine, but it can not be said that taking vitamin B2 does not have any side effects on the human body. Excessive intake of vitamin B2 will affect the absorption or utilization of other nutrients, long-term excessive intake will certainly cause harm to the body. The recommendation of vitamin B2 by Chinese Nutrition Society is 1.4mg days for adult males, 1.2mg days for females, not for unlimited recommendation. Vitamin B2 deficiency is often not a single deficiency, but also accompanied by the lack of other B nutrients. Vitamin B2 deficiency is rare. On the contrary, sometimes it is not the disease or symptoms caused by vitamin B2 deficiency, but the deficiency of vitamin B2 absorption and utilization caused by various diseases or symptoms. For example, body infection, a variety of gastrointestinal ulcers, bleeding and other issues, often lead to loss or even lack of vitamin B2; protein – energy malnutrition with vitamin B2 absorption and utilization decreased. The physiological process of human body is extremely complex, and it needs a variety of nutrients to support, and the physiological function of various nutrients is different, the body needs are also different. These nutrients interact with each other in the body, or promote each other to absorb, or resistance to each other, can not be a single reaction. Over emphasizing the physiological function of a nutrient to the body is just as wrong as over emphasizing the need for a certain food. Vitamin gastrointestinal disorders, such as diarrhea, infectious enteritis, allergic bowel syndrome, can lead to vitamin B2 deficiency. Hormonal disorders, such as thyroid hormone disturbances, can affect the use of vitamin B2. Vitamin B2 and other water soluble vitamins were lost in patients treated with diuretics and hemodialysis. Phenobarbital can increase the excretion of vitamin B2. Vitamin B2 is very sensitive to light and is rapidly oxidized and exposed to light and exposed to air. So you need vitamin B2, every time after taking the medication to tighten the bottle cap, and placed in the light.

你所不知道的!维生素B2不能随便补 维生素B2缺乏病是非常常见的疾病。维生素B2又称核黄素,它参与糖、蛋白质及脂肪代谢;维持动物生长、正常视觉及皮肤与黏膜的健康。维生素B2缺乏病(vitamin B2deficiency),又称核黄素缺乏病(ariboflavinosis)又名燕口疮或口吻疮,是由于机体内维生素B2缺乏或不足所引起以阴囊炎、唇炎、舌炎和口角炎为主要表现的综合征。但是,如果因为担忧患上维生素B2缺乏病而滥用维生素B2,对人体健康有害无益。 正常情况下,从食物中摄取的维生素B2就能满足人的需要。维生素B2广泛存在于奶类、蛋类、肉类、动物内脏、谷类、蔬菜和水果等食物中(动物性食物里的含量高于植物性食物)。但食物中维生素B2的含量不是太高,又有很多因素会导致其破坏丢失和利用不良,所以维生素B2是人们常会缺乏的一种维生素。 过量补充也有副作用 维生素B2是水溶性维生素,虽然摄入过量会从尿液中排出,但并不能说过量服用维生素B2对人体没有任何副作用。过量摄入维生素B2会影响其他营养素的吸收或利用,长期过量摄入肯定会对机体造成危害。中国营养学会关于维生素B2的推荐量为成年男性1.4mg 天,女性1.2mg 天,并非为无限量推荐。 维生素B2即使缺乏,也往往不是单一的缺乏,还会伴随其他B族营养素的缺乏,单纯维生素B2缺乏的情况很少见。相反,有时不是因为维生素B2缺乏引起的疾病或症状,而是各种疾病或症状造成维生素B2吸收利用障碍而致缺乏。比如,机体感染、各种消化道溃疡、出血等问题,往往会造成维生素B2的丢失甚至缺乏;蛋白质-能量营养不良时伴有维生素B2吸收利用减少。 人体生理过程极其复杂,需要多种营养素的支持,而且各种营养素的生理功能不同,机体的需求量也不同。这些营养素在体内相互影响,或相互促进吸收,或相互抵抗,不可能单一反应。过度强调一种营养素对身体的生理功能,就像过度强调机体需要某一种食物一样错误。 维生素 胃肠功能紊乱,如腹泻、感染性肠炎、过敏性肠综合征等可导致维生素B2的缺乏。体内激素紊乱,如甲状腺激素紊乱可影响维生素B2的利用。使用利尿剂和进行血液透析的病人,维生素B2和其他水溶性维生素丢失增加。苯巴比妥类药物会增加维生素B2的排泄。 维生素B2对光很敏感,在光照条件下且暴露于空气中会被快速氧化而失效。所以需要维生素B2者,每次服药后要把瓶盖拧紧,并置于避光阴凉干燥处储存,在有效期内服用。相关的主题文章:
