While grapefruit doesn’t have any magical fat-burning properties, it can help dieters feel full with fewer calories. This is attributed to the plentiful amounts of soluble fiber, which take longer to digest. Having half a grapefruit or a glass of grapefruit juice before a meal may help fill you up, so you eat fewer calories during the meal.
Grapefruit is also vitamin rich offering you an extra boost of a full range of B vitamins with the exception of vitamin B12 and about 28mcg of folic acid. They also contain potassium and magnesium as well as trace amounts of iron and zinc.
For a juicy grapefruit, choose one that feels solid and weighty. Look for a shiny, smooth skin to be sure of freshness. Reject those with soft areas, large brown spots, or dull dry-looking skin. Grapefruit can keep a week or slightly longer at room temperatures of 65° or higher. For longer storage, about six to eight weeks, store the fruits in the fruit and vegetable keeper of the refrigerator.
