Although they are different to the flu, having the symptoms of a cold-like a cough, sore throat and runny nose-can be bothersome. A severe cold can make you feel weak and ill too. Most colds are caused by viruses. Antibiotics are not effective against colds because they only fight bacteria.
Vitamin C Content. A 100-gram serving of orange or lemon provides you with 53 milligrams of vitamin C, which is 88 percent of the daily value of 60 milligrams per day. This serving equals either one small orange or slightly less than two lemons.
Although all tomatoes contribute to your vitamin C intake, there are different amounts of vitamin C in different varieties. For example, raw green tomatoes contain 23.4 milligrams, orange tomatoes contain 16 milligrams and yellow tomatoes contain 9 milligrams per 100 grams, which is slightly more than half of a large, 3-inch tomato. Sun-dried tomatoes are much richer in vitamin C, containing 39.2 milligrams per 100 grams.
