Oranges are well known for their high concentration of vitamin C, but citrus fruits also contain many other vitamins and nutrients. Oranges also contain vitamin A, many B vitamins, and vitamin E, making them a regular part of a healthy, balanced diet.
Vitamin A is an important nutrient for vision and skin health. However, high doses can be toxic: an overdose can damage the skin, weaken or break bones, and induce fatigue and vomiting. Therefore, you must ensure that you do not exceed the recommended daily doses of this vitamin.
B complex vitamins
The B complex vitamins are water-soluble vitamins that play an important role in cellular metabolism. B vitamins found in oranges include: Vitamin B1, or thiamine, which helps the body metabolize protein, fat, and carbohydrates. Vitamin B2, or riboflavin, which converts carbohydrates into energy and activates vitamin B6 and folic acid. Vitamin B3, or niacin, which forms fats from carbohydrates and regulates cholesterol. And vitamin B5, or pantothenic acid, which helps the body get energy from fat, creates cholesterol, and helps stimulate the adrenal glands. Vitamin B9, or folic acid, which helps the body make red blood cells. and vitamin B6, which regulates mood and mental processes by helping to form neurotransmitters, dopamine, the hormones melatonin, and serotonin.
Vitamin C is a water-soluble vitamin that acts as an antioxidant and contributes to the overall health of the body in many different ways. Helps reduce platelet aggregation and hardening of the arteries, may protect the body against certain types of heart disease. It also strengthens blood vessels and muscles, helping the body to produce collagen, and is also a natural antihistamine. Vitamin C also contributes to healing, fights viruses, helps in the formation of bile in the liver and detoxification of the body.
Vitamin E helps the body make glucose and has antioxidant properties that may help protect the body against some cancers and heart disease. Vitamin E may also help protect against toxins from air pollution and relieve symptoms associated with PMS, cataracts, skin damage from ultraviolet light, diabetes, and some neurological disorders. Because vitamin E increases the level of activity of the immune system, it has some benefits for people with rheumatoid arthritis and asthma.
