Flu Prevention

Sunkist oranges can help keep your immune system in optimal condition during the pesky cold and flu season. While there is no evidence that vitamin C prevents the common cold, a published summary of research studies suggests that vitamin C may have a modest effect on shortening the duration or lessening the severity of a cold if it is consumed before the onset of illness.1 During cold and flu season it is best to up your intake of vitamin C. Remember, unlike some vitamins, vitamin C cannot be stored by the body; so, it is important to replenish regularly to stay healthy and avoid the flu this season. Just one medium orange provides more than 100% of your daily vitamin C needs.
