The key question about vitamin C.
Vitamin C is a water-soluble vitamin that contributes a lot to our health. Since vitamin C is sensitive to heat, I had recently been wondering whether a rose hip tea brewed with boiling water still contains vitamin C.
In my research, I found that vitamin C only breaks down at a temperature of around 190 ° C. Boiling water has a temperature of 100 ° C. A rosehip tea therefore still contains vitamin C, which helps prevent colds, among other things.
Woher kommt der Begriff “Ascorbinsäure”?
Mit anderem Namen heißt das Vitamin C “Ascorbinsäure”. Der Name kommt von der Vitamin-C-Mangelerkrankung Skorbut, die besonders früher bei Matrosen auf hoher See aufgetreten ist, da sie keine frischen Früchte zu essen bekamen. Das “A” vor “scorbinsäure” weist auf die Verneinung hin. Somit lässt sich die Mangelerkrankung Skorbut durch Vitamin C verhindern.
Radical scavenger vitamin C and its effect on iron
Among other things, vitamin C is a radical scavenger. That means it destroys the free radicals that damage our cells in the body. Among other things, vitamin C acts as an antioxidant and promotes iron absorption. If a vegetarian or a vegan eats vitamin C in the form of kiwi fruit, for example, with an iron-based plant meal, he then enhances the plant food and a larger amount of iron is absorbed by the body. The non-heme iron from the plants becomes heme iron as found in animal products.
Vitamin C for smokers and for colds
Ascorbic acid is also very important for smokers because they have a higher need for vitamin C due to cigarette smoking. Smokers in particular should always pay attention to a very healthy diet.
Kiwis, acerola cherries and Camu-Camu contain high amounts of ascorbic acid and the kiwis in particular are now available all year round.
If you caught a cold or flu, you should consume a lot of vitamin C, since vitamin supports the immune system. Get kiwis in stock for a few days. If you buy too many kiwifruit, they will change their taste very strongly after four to six days and spoil.
The German Nutrition Society recommends a daily dose of 100-110 mg ascorbic acid per day. However, you do not need to worry that you are consuming too much vitamin C because it is water-soluble and the amounts that are too much are excreted in the urine.
