It can be found in some animal-based foods in its pre-made form, or found in plants in the form of beta-carotene -- a compound your body digests to form two vitamin A molecules. Yellow and dark green vegetables and fruits are good sources of the carotenes, including beta-carotene.
With the flu, you may feel very weak and fatigued for up to two or three weeks. You'll have muscle aches and periods of chills and sweats as fever comes and goes. You may also have a stuffy or runny nose, headache, and sore throat.
The flu can take many forms. Classically, the flu begins abruptly, with a fever in the 102 to 106 degree range, a flushed face, body aches, and marked lack of energy. Some people have other systemic symptoms such as dizziness or vomiting. The fever usually lasts for a day or two, but can last five days. Somewhere between day 2 and day 4 of the illness, the âwhole bodyâ symptoms begin to subside, and respiratory symptoms begin to increase.
