Like most citrus fruits, tangerines are rich in vitamin C, which is good for your immunity. Vitamin C works to boost your immunity by acting as an antioxidant that protects your cells from the damage caused by free radicals. Free radicals are highly reactive atoms that are produced when the substances in your body react with each other. This process is called oxidation, and the free radicals that oxidation produces can trigger cell death. Vitamin C's antioxidant power comes from its ability to scavenge free radicals and disarm their propensity for damage.

Pectin is a complex oligosaccharide that acts as an adhesive between the cell walls of tangerines and other types of fruit. A study published by the American Society of Microbiology showed that when digested, pectin is fermented within your intestines and can increase the number of beneficial microflora found in your gut.

The fibrous white tissue that is found between the segments of tangerines is called the lamella, and this membrane is rich in soluble fiber. One of the most beneficial effects of a diet high in soluble fiber is the reduction of cholesterol found in your blood. Soluble fiber lowers cholesterol by forming a thick, gel-like substance in your intestines when it is being digested. This substance slows the absorption of cholesterol and reduces the low-density lipoprotein in your blood. The dietary recommendation of soluble fiber is 10 to 25 mg per day.

Eating a well-balanced diet that is mostly fruits and vegetables is a smart way to manage your weight. The high fiber content of tangerines can help keep you feeling fuller for a longer period of time. Feeling full can impact your weight, because when you feel satiated, you are less likely to overindulge and make poor food choices.
