If you're looking for a single vegetable or piece of produce that can provide you with the widest range of health benefits, onion is a good place to look. While it may not be the richest source of different vitamins and minerals, onions nonetheless give a hearty mixture of different nutrients that your body needs. The bonus of natural immune system boosting properties and other benefits makes the onion something that everyone should include in his or her diet.
Onions vary in composition and dietary benefits for a number of reasons. The best onions are those that are darkest in color and which have not been stored for a long period of time. Although the fact that onions can be safely stored for much longer than most other vegetables has historically made them a good choice of crop, the longer that the vegetable is stored the more nutrients that seep out of it. Here are four important health benefits of onions.
Onions are good sources of several vitamins, and in particular vitamin A, vitamin C and vitamin E. All three of these vitamins are necessary for standard bodily processes, and vitamin C in particular can help to boost your immune system. This is one of the many reasons why onions have been used in medical procedures and to promote general good health for thousands of years.
2. Folic Acid
Folic acid is helpful in regulating certain other systems in your body. It is typically found in different types of fruits, but onions are unique in that they contain a hefty amount of folic acid and they are a vegetable. In order to mix up your intake of produce but still get your recommended dosage of this nutrient, consider using onions.
3. Anti-Bacterial Properties
Onions and garlic are both pungent in odor and flavor. This makes them preferable for many people and also makes other people choose to avoid them. However, linked in with this pungency is the fact that both of these vegetables are excellent natural antibacterial agents. By eating a diet that is heavy in onions, and particularly one that is heavy in onions that have not been cooked through thoroughly, you can boost your body's natural protection system against bacteria. This will mean that you'll be less likely to experience a variety of different types of infections.
Many types of onions are high in iron. Red onions in particular have the highest concentrations of iron. This can be helpful for a number of reasons. Iron helps to keep your blood the proper consistency and thickness. Onions can prevent anemia, or a general thinning of the blood. They can also boost the health and strength of your blood cells in a number of other ways as a result of the iron that they contain.
