Suplemento de Vitamina C previne resfriado? | #InstanteBiotec 36


During the fall and winter see many cases
of cold and flu, and probably someone have already told you to take those
vitamin C supplements to eliminate them. But do they work? Vitamin C, or ascorbic acid, is a
essential nutrient that helps in our immune system, enhances iron absorption, acts
on the regeneration of muscles, skin, teeth and bones, in collagen formation, hormone production and metabolism in general. Moreover, it is a powerful antioxidant. Low Vitamin C can lead to scurvy,
a disease historically known to affect sailors during long voyages in which
they had no access to foods like fruits and vegetables. Too much vitamin C can result in diarrhea,
nausea, kidney stones and excess absorption of iron. As this vitamin is soluble in water when
consumption is greater than 2000 mg per day, the body eliminates the excess in the urine. The best way to get this nutrient
is through food, such as orange, pineapple, kiwi, papaya, tomato, peppers, broccoli
and spinach. According to Anvisa (Brazilian Health Agency), the recommendation is at least 45 milligrams per day. But the FDA recommends 90 milligrams per day. But how much fruit and vegetable does it correspond? 150 g of papaya contains about 95 mg
of vitamin C. 100g of broccoli contains 89 mg. And an orange, about 130 g, contains about
70 mg of vitamin C. If you include any of these vegetables in
your daily diet, you are probably consuming enough vitamin C. But do vitamin C supplements, which
we find in pharmacies in the form of capsules and tablets, fight cold? A meta-analysis conducted in 2013
comparing various studies with over 11.000 people showed that taking 200 mg of vitamin
C or more per day, did not prevent cold. Specifically for treating cold
with vitamin C, it also showed no better effects than placebo. They have also shown that taking vitamin
C did not shorten the duration of cold in an expressive way and neither has made symptoms lighter. That is, the medicine could not scientifically support this indication. Still you can buy these supplements,
although its effectiveness is unproven. This is because the law does not consider
these supplements as drugs. It means that they do not go through that
series of tests that drugs need to go to prove their effects, and the same sanitary requirements are not required in their production. This leaves the population unprotected and exposed to unsafe and low-quality products. To escape from the flu you can get the
tri- or tetravalent influenza vaccine that includes H1N1. And to not catch cold,
always sanitize your hands, avoid staying in closed environments with many people and
contacting with someone who’s already sick. If you like this video give a thumbs up
and also share it in your networks. See you next time.

  1. Gostei do vídeo, mas ele partiu do pressuposto de que eu sei pra que serve a Vit C, algo que não é verdade, nem sabia que prevenia resfriado, afinal, a Vit C previne? e o que não previne é o suplemento?
