Question
Since vitamin C is soluble in water, any excess is excreted. Is it better to get all of your RDA at one meal or spread it out over the day? Explain your position. Many soft drinks, snack foods, and energy bare have vitamin C in them. Why do you suppose that is so? If vitamin C is excreted continually, is it possible to get too much? If copper destroys the vitamin C content of foods, would it be prudent to expect that other metals may have the same effect? If so, which metals might you suspect? How does the fact that copper metal destroys vitamin C relate to the principle of green chemistry, safer solvents and auxiliaries, if we consider a copper pan an auxiliary?Explanation / Answer
1. Since excess vitamin C is excreted, so it is beeter not to take all the amount at a single meal but to spread it out over the whole day.
2. Soft drinks, snack foods and energy bars have vitamin C in them. It is due to their content. The ingredients that have been used to make these items contain quantities of viamin C.
3. Since Vitamin C is excreted continuously, it is not possible to get too much.
4. Yes, other metals can also destroy the vitamin C content of foods. Vitamin C is actually a mild acid, such as citric acid, so the metals which are basic in character can neutralise the acidic content of vitamin C. Example, copper, zinc etc.
