VITAMINA C: BENEFÍCIOS, PROPRIEDADES E ALIMENTOS
"Você está resfriado? Tome uma boa dose de vitamina C!" Quantas vezes você já ouviu essa frase? A vitamina C goza de um status de superestrela entre os nutrientes que consumimos todos os dias. Vamos descobrir juntos para que serve e quais são os benefícios da vitamina C.
O que é vitamina C
A vitamina C, ou ácido ascórbico, pertence ao grupo das chamadas vitaminas hidrossolúveis, nomeadamente aquelas que não podem ser acumuladas no organismo, mas devem ser ingeridas regularmente através da dieta alimentar. Além de derreter na água, a vitamina C é sensível a altas temperaturas, por isso os benefícios da vitamina C são perdidos no caso de cozinhar em água.
O que a vitamina C faz?
A vitamina C, ou ácido ascórbico, participa de muitas reações metabólicas e da biossíntese de aminoácidos, hormônios e colágeno. A vitamina C é boa para a pele? Sim, graças aos seus fortes poderes antioxidantes, a vitamina C ajuda o corpo a proteger a nossa pele do stress oxidativo do ambiente apoiando as funções da barreira epitelial contra os agentes patogénicos, na verdade é uma ajuda na cicatrização de feridas. Além disso, outros benefícios da vitamina C são aqueles que facilitam a formação de colágeno, promovem dentes e gengivas saudáveis e aumentam as barreiras do sistema imunológico.
A vitamina C também entra em ação para o desenvolvimento harmonioso do organismo e para a reparação dos tecidos, aliás é essencial para estimular a cicatrização de feridas.
A nível cerebral, a vitamina C é responsável pela criação do neurotransmissor denominado norepinefrina, que ajuda a controlar a utilização de substâncias contidas no sangue, nomeadamente a glicose.
Alimentos com Vitamina C
A vitamina C está contida principalmente em alimentos frescos: em alguns tipos de frutas e vegetais, como laranjas, morangos, tangerinas, kiwis, limões, espinafre, brócolis, tomate e pimentão. É uma vitamina particularmente sensível à luz, ao ar e ao calor, pelo que se deteriora facilmente durante os tratamentos de armazenamento e cozedura. Para aproveitar plenamente os benefícios da vitamina C, esses alimentos devem ser armazenados no máximo 3-4 dias e consumidos crus.
Aqui está uma lista de alimentos que contêm mais vitamina C por 100 g:
- pimenta 229 mg
-groselha preta 200 mg
-pimentas 151 mg
-kiwis 85 mg
-couve de Bruxelas 81 mg
-couve-flor 59 mg
-morangos 54 mg
-espinafre 54 mg
-laranjas e limões 50 mg
A quantidade de vitamina C necessária por dia depende da sua idade. De acordo com os Institutos Nacionais de Saúde, as quantidades médias diárias recomendadas para homens são de 90 mg e para mulheres de 75 mg (durante a gravidez, 85 mg).
Deficiência de vitamina C
A falta de vitamina C, ou ácido ascórbico, causa o escorbuto, doença que no passado era muito difundida entre os marinheiros que viviam em navios e ficavam meses a fio sem comer alimentos frescos. Os sintomas do escorbuto são um quadro de apatia, anemia e falta de apetite seguido de outros sinais como sangramento nas gengivas, queda de dentes, dores musculares e sangramento subcutâneo.
Excesso de vitamina C
A ingestão excessiva de vitamina C, ou ácido ascórbico - que pode ser causada por uma alimentação desequilibrada ou pelo abuso de suplementos - pode causar problemas renais, com formação de cálculos, ou overdose de ferro, pois a vitamina C promove sua absorção.
O excesso de vitamina C pode causar sintomas como dores de cabeça, azia, vómitos, diarreia, gastrite e cólicas abdominais, mas também fraqueza, tonturas e ondas de calor repentinas.
Sometimes last month I invested my bitcoin into a trading platform hoping to get back my invested funds with profits. I was lured by a blockchain expert who claimed to work under Blockchain and as an amateur that I was, I fell for the scam. I invested quite a large amount, about 40000 USD worth of Btc and for a few days, my funds grew and generated profit until I wasn’t able to login into my account anymore. I was scared I lost my funds as I wasn’t able to contact the company for help and I was blocked from all access. I really got depressed and I really needed help but I couldn’t get help from authorities so I surfed the internet on how to get back my funds. I was lucky enough to come across Blockchainrecall.com, a group of experts who surprisingly within a space of 5 days recovered all my scammed funds back to my safety. I am here to testify to the help I got and I hope someone out there who might be in the same situation as I was would find it useful.
Investing in bitcoin has been my thing for years now. I started a few years back when I invested about 300,000 usd into a trading platform and I didn’t regret it. Few months back I was introduced to a new platform online but I didn’t notice I was being played. After I invested some cash I was expecting to make my profit but suddenly I couldn’t gain access to my account anymore. My funds including profit are all gone. I already made quite a lot of profit and I could not let it all go. I contacted an online recovery team Blockchainrecall.com who helped me recover both my invested funds and profits with a space of 5 working days. Thanks to Blockchainrecall.com for the help they give.
I’ve read many stories about people recovering their funds after losing them to scammers and I thought it was another scam, but after losing all my funds to a cryptocurrency investment scam, I had no other choice but to research a recovery platform that can help me with the recovery of my funds. I stumbled upon Bitcoin Recovery Wizard online and contacted them immediately. I was very impressed by their service and how quickly they helped me recover my cryptocurrency funds. Truly their service is top-notch. I’m highly recommending them to everyone who wishes to recover their funds.
