Driveon, if you want to get vitamin c from natural sources, you should also look into that. Orange juice isn't the only or even the best source of vitamin C. First, unless you're buying oranges and squeezing them yourself, it's pastuerized. Vitamin C is destroyed at temperatures well below those of pastuerization. Additionally, it degrades over time. So, if that container of orange juice has been sitting in the warehouse, the store, or your fridge for a week or two, there won't be much C in there at all by the time you drink it.
foods are much higher in C than oranges, for example:
Code: Select all
Amount of C
Fruit (mg per 100g of fruit)
Acerola Cherries 1677.6
Red Bell Pepper 127.7
Green Bell Pepper 80.4
Raw Peas 80.0
The nutrition content of food also can vary greatly depending on whether they are harvested in or out of their natural seasons. For example, the average amount of C found in tomatoes in the summer months is 26 mg per 100 grams of fruit. The average in the off season is only 10 mg. The citrus fruit season is winter when not so many other fresh frutis are around, which is one of the reasons it has the reputation of being very high in vitamin C.
