Top 5 health benefits of asparagus
1. Supports gut health
2. May ease hangovers
There is some evidence that asparagus may help ease some of the symptoms of a hangover due to both its fibre and flavonoid (protective plant compound) content. The research even suggests that asparagus may help reduce damage to the liver caused by alcohol, although further research is needed.
3. A rich source of folate
Asparagus is a rich source of folate, a vitamin which is important for making red blood cells and for cell division – the synthetic version of this vitamin is folic acid.
Folate is an essential nutrient during pregnancy because it is needed for foetal development and protects against neural tube defects including spina bifida. Just 120g of asparagus (boiled) will provide your daily reference intake (RI) (200mcg). However, the NHS recommends that women planning a pregnancy or in the first trimester of pregnancy obtain 400mcg of folic acid a day.
4. May help relieve inflammatory conditions
5. May lower blood pressure
It's understood that increasing your potassium intake while reducing salt has a positive effect on high blood pressure. Asparagus is a good source of potassium, with one portion providing about 5% of your daily reference intake (RI).
In addition to this, animal studies suggest that a natural compound in asparagus acts as an ACE inhibitor helping dilate blood vessels and lower blood pressure. It does this by preventing an enzyme in your body from producing angiotensin II, a substance that narrows blood vessels making your blood pressure higher. Although this is a promising finding, the same effects have not, to date, been replicated in humans.
Is asparagus safe for everyone?
Asparagus is high in purines, compounds that increase the body's production of uric acid and may influence conditions like kidney stones and gout. Therefore, if you've been advised to reduce levels of purines in your diet, asparagus may not be appropriate for you.
It is possible to be allergic to asparagus – if so, you may also be allergic to other members of the same botanical family, including garlic and chives.
If you are not accustomed to fibre in your diet, eating a generous portion of asparagus in one sitting may result in bloating and wind. Some people also cite having smelly urine after consuming asparagus. This is because asparagus contains a compound called asparaguisic acid which is broken down into sulfur-containing compounds, which have a strong smell.
