6 benefits of asparagus 


1. Supports digestive health 

Asparagus is a fantastic prebiotic food that helps support the digestive system. It contains a type of prebiotic fiber called inulin, which doesn’t break down until it enters the large intestine. 


Inulin feeds the microbes in your intestine, which helps to build up friendly bacteria and improve digestion. It also helps to maintain healthy blood sugar levels. 


2. Contains many essential vitamins

Asparagus is an excellent source of vitamin K. Vitamin K plays an important role in blood clotting and is essential for bone health.


One cup of asparagus contains 91 mcg of vitamin K, 100% of the vitamin K women need each day. Men need a little more vitamin K, but a cup of asparagus still provides 75% of the recommended daily allowance.


Asparagus contains vitamins B1, B2, B3, B5, and B6! B vitamins provide you with energy and help the body deal with stress and anxiety. Asparagus is high in the essential nutrient phosphorus, which also improves energy. 


Asparagus is a great source of folate. Folate, also known as vitamin B9, is very important for a healthy pregnancy. Folate plays a key role in preventing birth defects. Folate supplements are typically made with the synthetic version of folate, folic acid. 


It’s always best to get your vitamins and minerals from whole food sources rather than a supplement. Folic acid is not as easily absorbed by the body as the folate that’s found in food. 


3. Contains antioxidants  

Antioxidant-rich foods like asparagus and other green vegetables are typically great sources of vitamin C, vitamin E, and vitamin A. 


Antioxidants work to fight free-radical damage and oxidation in the body. They play an important role in cancer prevention and support a healthy immune system.  


Asparagus is also high in sulfur, which is why it can sometimes alter the smell of your urine. Sulfur is important for building the antioxidant glutathione in your liver.

4. Natural diuretic 

Fresh asparagus has natural diuretic properties, so it has the potential to detoxify the kidneys. It’s high in potassium and low in sodium, which helps to push fluid out of the body. Asparagus also helps protect against kidney stones. 


5. Promotes healthy blood sugar levels

Asparagus contains the mineral chromium, which helps combat insulin resistance. This interesting study examines the antidiabetic properties associated with asparagus. 


Because asparagus is very low in carbohydrates, it will not spike insulin. This will keep you in ketosis and help you lose weight.


6. Supports cardiovascular health

Foods like asparagus have the potential to lower high blood pressure due to its high potassium, high magnesium, and low sodium content.


Asparagus is also rich in phytochemicals called saponins which have some promising potential health benefits. Saponins help to remove plaque from blood vessels and prevent heart disease. In this study, asparagus extract was used to prevent atherosclerosis.
