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.
Lemon Aid â The Need-to-Know. Lemons are packed with flavor, but (thankfully) not calories â the juice of an entire lemon has only 12 calories but a whopping third of the daily recommended value of vitamin C. But it's more than just a diet-friendly flavor-booster. In these post-scurvy days (yup, citrus fruits were the cure for scurvy back in the old days), lemons' vitamin C is still essential: It plays a role in building collagen in the body â that is, one of the key materials in blood vessels, tendons, ligaments, and bones.
